Image 1 – Two story Touchwood home in Albany, Auckland.

1.1 The Touchwood building system consists of a construction method that incorporates a conventional style foundation, floor, roof, joinery and cladding systems with a unique pre-fabricated all-in-one solid wood wall and brace panel. 1.2 The wall panels are pre-fabricated in a factory controlled environment and consist of machined horizontal 180x43mm tongue and groove planks tied together with 70x45mm H1.2 SG8 vertical framing members and plates/lintels that suit the overall design. Braced panels are incorporated into the wall using a special adhesive that joins the wall members in a permanent lateral resistant state. 1.3 Once the foundations and floors are constructed the Touchwood walls are delivered to site and lifted into place using a crane or hiab and fixed off using screws and other proprietary hardware. Roof framing and other systems can then be installed to specific product details. 1.4 After the building has been made weather tight, the solid wood walls are finished by sanding and coating with selected low VOC paint products.

1. PRODUCT DESCRIPTION


Figure 1 – Standard 3D exterior wall section.

2.1 The Touchwood building system has been developed for new

homes and light commercial structures up to two stories with a maximum

importance level of 2 and which fall within the scope of NZS3604: 2011 Clause

1.1.2.

2.2 External design wall heights greater than 2.7m, design wind speeds

greater than 50 m/s (very high wind), and heavy roof claddings fall outside

the scope of clause 2.1 above and require specific engineering design (SED).

2.3 Although the Touchwood system can be viewed as a whole, the

technical literature in this document mainly deals with the pre-fabricated

internal/external wall panels as independent from the roof and floor, with

special consideration given to bracing and roof-to-wall-to-floor structural

connections.

2.4 Foundations, floors and roofs are outside the scope of this technical

literature and must be treated within the provisions of NZS3604: 2011, the

relevant approved standard or SED.

2.5 Wall and roof claddings including building wraps and underlays are

covered under NZBC clause E2 and need to be treated in accordance with

2. SYSTEM SCOPE


E2/AS1/VM1 and other NZBC approved systems in accordance with the manufacturers design notes and specifications. 2.6 Touchwood wall panels have limited insulation values which depend on the building as a whole and must be treated using the calculation method from NZS4218: 2004 and tables from the New Zealand Building Code (NZBC) H1/AS1. See insulation values for complete wall/insulation/cladding combinations under the Design Information section of this document. 2.7 Internal and external moisture considerations are addressed within the provisions of the NZBC E2 & E3 acceptable solutions or verification methods as applicable. Attention has however been given to the in-service moisture content of the finished walls, and the average moisture contents of structural timbers during fabrication.

New Zealand Building Code (NZBC) 3.1 Based on the relevant compliance documents referenced herein, particular material investigations, and both in-use testing and in-service history, when the Touchwood walls are designed, built and installed in accordance with this document, the relevant provisions of the following clauses of the NZBC will be met:

B1 STRUCTURE: When used in line with this document, Touchwood wall panels will meet the performance provisions of clause B1.3.1, B1.3.2, B1.3.4 and the relevant physical conditions of NZBC B1.3.3 (a), (b), (f), (g) and (h)

B2 DURABILITY: Touchwood wall panels meet the performance provisions of NZBC B2.3.1 (a) – 50 years, provided the panels have been installed and maintained in accordance with this document and other technical details and literature. Other proprietary products incorporated into the walls such as nails, plates, straps, bolts and adhesives will also meet the provisions of NZBC B2.3.1 (a) – 50 years, provided installation and maintenance have been performed in accordance with this document.

E2 EXTERNAL MOISTURE: Touchwood external wall panels will meet the performance standards of NZBC by complying with E2/AS1/VM1 or other NZBC approved cladding systems.

E3 INTERNAL MOISTURE: Touchwood wall panels will meet the performance standards of NZBC by complying with E3/AS1.

F2 HAZARDOUS BUILDING MATERIALS: When Touchwood wall panels are installed and used in accordance with this document and other relevant technical literature, they will not present a health hazard. Therefore the performance provisions of NZBC F2.3.1 will be met.

Environment of Use 3.2 Exterior Touchwood walls were developed on the basis that they be suitably covered by selected cladding systems in accordance with NZBC

3. REGULATIONS


E2/AS1. When the building is externally lined in accordance with E2/AS1, a suitable equilibrium moisture content of 12% +/-2% can be maintained within the enclosed environment to prevent water ingress and meet the durability performance requirements of NZBC.

Degradation 3.3 Given the strength, environment and compatibility of the products that make up a Touchwood wall panel, along with the test data collected by the individual manufacturers of each element of the panel, it is considered highly unlikely that any integral degradation of the wall panel will occur within a 50 year time frame.

Adhesive Laboratory Testing 3.4 It is the opinion of Uroxsys Limited, by way of experimental proof of polyurethane adhesives on timber substrates, including wood swell stresses and shear strength test data, that the adhesive used in the TWB panels will maintain its integrity for a minimum period of 50 years. In-service History 3.5 The use of adhesives to manufacture structural members for use in residential and commercial applications has long been known, as in the examples of PRF (Phenol resorcinol formaldehyde) Glue-laminated Load Bearing Beams to PRF Laminated Plywood used in structural bracing. Evidence now exists to show that moisture-curing one-component polyurethane (PUR) adhesives compare equally if not better under long term permanent load than the conventional PRF glues. It was discovered that, in a ten year bending test with glue laminated timber beams under permanent load, that the beam deflection of the polyurethane adhesive compared almost identically to the PRF based product. It was also shown that the percentage increase in deflection per year for both adhesives, after a ten year period, was negligible. According to test data, the polyurethane adhesive was consistent for both indoor and outdoor use.

Maintenance 3.6 Touchwood wall panels will not require maintenance under normal use. If any damage of the wall or brace panel occurs, immediate repair or replacement must be carried out to maintain the structural integrity of the system. 3.7 Internal wood surfaces can be maintained by cleaning, or sanding and repainting with a suitable paint product. 3.8 Regular inspections and maintenance of the buildings cladding systems must be undertaken in accordance with the manufacturer’s specifications, and repaired immediately where any damage or degradation is found. Inspections should be carried out on a yearly basis.


Materials 4.1 The following materials are supplied by Touchwood and either incorporated in the wall panels or supplied directly to site with the pre-fabricated panels.

Enclosed Framing: SG8 H1.2 (boric treated) 70x45mm timber battens at 400mm and 600mm centres connected to plates, trimmers and nogs (cladding dependant); nogs typically are not required unless specified by the cladding manufacturer; SG8 H1.2 (boric treated) 140x35mm timber top plate; SG8 H1.2 (boric treated) 45mm thick lintels ranging in heights from 190mm to 290mm. All framing timbers used to have moisture content of 12% +/- 2%.

Wall Planks: Touchwood No.1 framing grade (SG6 equivalent) rough sawn Radiata Pine (heartwood) planks are kiln dried to an average moisture content of 12%, machined into the final tongue and groove profiled form and cut to length, individually submerged in a water based weather seal protectant (Damar Aquaseal), and dried ready for incorporation in a Touchwood wall. After wall panel prefabrication the product is stored in the factory under cover until ready for use at which time the moisture content is checked and must be within a range of 10-14% before being delivered to site. The final EMC of the in-use timber is expected to be 12% +/- 2%. Plank dimensions must be equal to the measurements shown in the manufacturer’s technical literature with only a slight allowable variation of +/- 0.1mm. For the Bondurox adhesive to be fully effective the tongue and groove timber surfaces must join together with a separation of no greater than 0.3mm.

Adhesive: Bondurox C polyurethane adhesive for use under factory controlled conditions in accordance with Touchwood technical details and related manufacturers specifications and authorisations.

Structural Connections: The Touchwood system uses 100mm 10 gauge zinc plated screws in both the pre-fabrication and on-site assembly. Other fixings such as, thru-bolts, nail-on plates, straps, ceiling ties and nail plates which are used to connect walls components to floors and roofs, and can be sourced from Touchwood or supplied by a local building material merchant.

Accessories: Sarking board to match walls is provided as an alternative ceiling lining option; End cappings and 135 degree mitre caps allow for additional design flexibility.

Handling and Storage 4.2. Touchwood wall panels are custom manufactured just days before on-site assembly and are stacked flat in a dry environment prior to delivery. Support bearers must be used under the wall to prevent sagging of wall

4. MATERIALS


panels. After delivery to site, wall panels stored outside must be well covered with good ventilation and out of direct sunlight.

Image 2 & 3 – From factory to site assembly.

4.3 Due to the pre-fabricated nature of Touchwood walls, orderly stacking of the panels in the factory allow them to be site-assembled without double handling which can minimise unnecessary damage or the use of excessive temporary bracing. In some cases the walls must be factory stacked in order of strength to minimise weight damage that can occur in large packets; this must take priority over site assembly processes to minimise serious damage.

5.1 This document must be read in conjunction with all Touchwood technical literature including construction details, structural calculations, design notes, test results and other relevant documents. See References Section 9 at end of this document. 5.2 This document may form part of a building consent specification with the purpose of demonstrating compliance with the NZBC, in which case this document may be the instrument of reference with respect to plans and specifications contained in the building consent file.

General 6.1 A common method used by designers when conceptualising a new Touchwood home is to consider the building as equivalent to a light timber framed building within the provisions of NZS3604: 2011. Bracing is calculated as usual from NZS3604 Section 5 using Touchwood Wall Brace (TWB) values from the formal P21 test results listed in this document and other Touchwood literature. Exterior walls and braced walls are then substituted with 113mm thick Touchwood panels and interior walls are substituted with 43mm thick

5. TECHNICAL DOCUMENTS

6. DESIGN INFORMATION


Touchwood panels; exposed posts and beams are used where required for larger openings. 6.2 When used in accordance with this document and the manufacturer’s technical literature, the Touchwood building system will substitute for the wall requirements of Section 8 of NZS3604: 2011 for buildings not requiring specific design. 6.3 The manufacturer’s technical literature contains generic construction details and design information that can be used as a starting point for designers and industry professionals. 6.4 Wall bracing elements typically range from 600mm to 2400mm wide but can exceed these dimensions where required. 6.5 The Touchwood building system does not limit the use of conventional style framing with painted plasterboard linings, and these can easily be incorporated into a Touchwood home; and visa-versa, Touchwood walls may also be designed into conventional construction methods. 6.6 Although one of the standard features of a Touchwood home are light coloured painted plasterboard ceilings, Touchwood provides the option to line ceilings with a matching 180x19mm sarking board to provide for the full wood effect. The sarking board may also be used to line over conventional type house framing. 6.7 Sound rated Touchwood walls are achieved by assembling walls in a similar fashion to those detailed in NZBC G/AS1 using Touchwood 43mm and 19mm wall planks in place of plasterboard linings. Walls must be completely separated for impact transmission to be reduced to a suitable level. Sound rated walls will only be effective if all parts of the wall are considered and special consideration should be given to door trims and openings where vibrations have a high potential for leakage. 6.8 Touchwood Solid Wood Walls must be adequately sanded to remove Damar Aquaseal dip prior to paint application. For clear finish, two coats of water based acrylic are applied as per the manufacturer’s instructions with sanding between coats. Where a blond or white wash finish is desired, the first coat should be a White Pigmented Wiping Stain applied as per manufacturer’s instructions with two top coats of acrylic clear for protection.

Structure Background 6.9 The Touchwood building system was developed in collaboration with APR Group Engineering Consultants for its primary use in residential and light commercial situations. An in-house chartered professional engineer – Paul Richardson - was selected to specialise on Touchwood related work. PR Engineering Consultants was eventually set up and has been providing professional services to Touchwood ever since. To date all Touchwood designs have been engineer approved for structural integrity and robustness. 6.10 Touchwood walls are designed to meet the relevant performance requirements of the NZBC for B1 STRUCTURE and B2 DURABILITY by the following verified design standards:

- AS/NZS1170: 2002 - NZS3602: 2003 - NZS3603: 1993


- NZS3604: 2011 - NZS3605: 2001 - NZS3640: 2003

Permanent and Imposed Loads 6.11 Touchwood walls have been designed to withstand permanent loads as both individual wall panels and as a body of interconnected walls. When walls are designed and constructed in accordance with this document, and other relevant design literature, the system as a whole notably exceeds the durability and structural performance necessities of the NZBC. 6.12 Live loads are designed in accordance with NZS3604 and where applicable AS/NZS1170. Wall Bracing Elements 6.13 Touchwood wall braces (TWB’s) are built into the wall panels during factory fabrication in accordance with BU values on the council approved bracing plans and to meet the requirements of regional wind and earthquake demands as calculated in Section 5 NZS3604: 2011. 6.14 The TWB unit values shown below were determined experimentally in the timber engineering laboratory at Ensis Rotorua in accordance with the BRANZ P21:2010 racking test evaluation technical paper.

Table 1 – Touchwood Wall Brace Units (BU’s) derived from BRANZ P21 Tests.

WIND BU’s/meter

TWD6 600 160 138 TWD9 900 152 137 TWD12 1200 164 161

6.15 Bracing units are based on wall panel heights of 2.4m. For other panel heights the brace rating is calculated by multiplying the BU value by 2.4m and dividing by the proposed average brace height in meters. 6.16 Touchwood wall panels containing braces have very high in-plane strength and are limited by the floor connections as reflected by Clause 5.4 NZS3604:2011.

Wind Speeds 6.17 Touchwood homes can be designed to suit regions of very high wind speeds of up to 50 m/s in accordance NZS3604: 2011. Extra high wind speeds greater than 50 m/s are outside the scope of this manual and require specific design to meet the performance requirements of the NZBC. 6.18 Unusually complex homes designed for very high and extra high wind speeds must be approved by PR Engineering Consultants in order to mitigate possible weak points in the structure. 6.19 Other structural systems that form part of a Touchwood home, such as foundations, floors, roofs and claddings, must also be designed for the appropriate wind speeds in order for the finished building to perform acceptably as a complete unit. Impact Resistance 6.20 Touchwood wall panels are highly resistant to impact under conditions of normal wear and tear. Due to the tough nature of solid wood, Touchwood wall panels also perform extremely well under high wear situations such as in a public space or commercial environment.

Fire Prevention 6.21 Touchwood wall panels contain combustible materials and must be adequately separated from sources of heat such as chimneys, fire-places, flues and fuel-burning appliances in accordance with the performance requirements of NZBC C2.2. Combustion appliance manufacturer’s specifications must be investigated prior to installing near Touchwood Walls.

Fire Spread 6.22 Contrary to Clause 6.23 above, Touchwood panels consist of a 43mm thick section of solid wood which (when exposed to fire) will form a


charcoal layer on the surface of the timber. The charred layer has an insulating effect such that temperatures only a short distance in from the char line will not raise sufficiently enough to impair the strength of the wood. Under NZS 3603 clause 9.4.2 solid Radiata Pine has a charring rate of 0.65mm per minute, giving the solid wood portion of the wall panel a minimum Fire Resistance Rating (FFR) of 60 minutes. This resistance to fire spread can be increased by applying a selective intumescent coating system designed especially for wood. 6.23 Interior wall surface finishes for educational buildings achieve compliance with C/AS4 and a material Group Number of 2 by using intumescent clear coatings as above. 6.24 Residential buildings closer than 1.0m to the relevant boundary require Fire Resistance Ratings (FRR) of no less than 30/30/30 as required by C/AS1 Part 5. This rating must also extend to the eaves projection (where applicable). An eaves projection closer than 650mm to the relevant boundary requires a FRR of 30/30/30 as well as the adjoining wall.

External Moisture 6.25 It is a functional requirement of the NZBC that buildings be constructed to provide adequate resistance to accumulation of outside moisture, and this is typically achieved by complying with the provisions of E2/AS1 or E2/VM1. 6.26 Touchwood walls must be protected from moisture ingress by means of an external cladding system. Selected cladding systems must be regularly inspected and maintained in accordance with E2/AS1 and the manufacturer’s requirements. 6.27 Depending on the buildings proposed location and cladding type, a drained ventilated cavity may be required as determined from the Risk Matrix assessment process in E2/AS1. It is important that air movement be restricted to the cavity and closed off from the roof & wall framing and the subfloor space with drainage to the exterior of the building located at the bottom.

Internal Moisture 6.28 It is critical that internal humidity be controlled in a manner that prevents condensation or penetration of moisture that could otherwise lead to fungal growth and structural damage. A Touchwood house design will achieve internal moisture control by complying with the provisions of NZBC E3/AS1. 6.29 In general, good ventilation and adequate room temperature will result in a healthy equilibrium content of moisture in the building. In most cases buildings will achieve this through the use of adequate window openings, mechanical ventilation, or both, and by complying with NZBC H1 Energy Efficiency. 6.30 An impervious finish is a standard feature of all interior surfaces to Touchwood walls and is easily achieved by the use of acrylic or oil based paint products. Extra attention should be given when specifying and applying paints in areas of high moisture generation or where water splash is common,


such as kitchens, laundries and bathrooms; moisture must not be allowed to penetrate into the wood substrate in these areas.

Energy Efficiency 6.31 Buildings designed and built in accordance with H1/AS1 and NZS4218 meet the Energy Efficiency performance requirements of the NZBC. 6.32 The thermal insulation requirements for a Touchwood building are achieved using the Calculation Method from NZS4218 by comparing the heat loss of the proposed building with that of the same building using the Schedule Method (the reference building). 6.33 Standalone exterior Touchwood walls when insulated with R1.8 70mm thick fibreglass batts will achieve a combined resistance rating of R1.96 as determined using Design navigator Construction R-value Calculator (www.design-navigator.co.nz). The total R-values for various common claddings shown in Table 2 below can be used with the calculation method for determining compliance with NZBC H1.

Sustainability 6.34 Notwithstanding the use of screws and glue, Touchwood walls are manufactured almost entirely from NZ Radiata pine; and because there will always be potential to grow forests in NZ, and assuming there is demand for solid wood buildings, the Touchwood wall system remains a viable means of supporting sustainability. 6.35 All timber used in the manufacture of Touchwood panels are locally grown and milled from Forest Stewardship Council (FSC) certified forests. The Forrest Stewardship Councils mission is to promote environmentally appropriate, socially beneficial, and economically viable management of the world's forests. 6.36 The timber content of a typical 90m2 conventionally constructed home equates to approx. 7.4m3 of NZ pine. The same house using the Touchwood system contains approx. 13.3m3 of pine, locking away almost twice the amount of CO2 thereby reducing the ever increasing concentration of atmospheric carbon.

7. CONSTRUCTION


Installation Skill Requirements 7.1 Touchwood wall panels are produced in a factory controlled environment by an authorised Touchwood manufacturer deemed competent and responsible by Frontier Solid Wood Homes Limited. During panel construction, proof of correct manufacturing techniques, in accordance with Touchwood technical literature, are documented through a series of checklists and photographs that can be referred to at a later date. 7.2 Touchwood homes must be constructed by a Licenced Building Practitioner (LBP) and personal approved by Frontier Solid Wood Homes Limited. Approved personal are given specific hands-on training about how to correctly assemble and affix Touchwood wall panels on site in accordance with approved plans and standard construction details. Approved Touchwood LBP’s are permitted to nominate other tradespeople to assist in the wall panel assembly on the basis they are supervised by the LBP.

Services 7.3 Touchwood wall planks are designed in a way such that the horizontal T&G joints form a void which can be used selectively for reticulation of electrical and communications cabling. The voids exist horizontally every 180mm allowing ample space for service cabling. End caps, posts and door jambs have similar rebates profiled into their design that allow for cabling to run vertically behind the timber member. Care must always be taken when installing members that electrical cables are not pierced during fixing. 7.4 Plumbing services will typically enter the building by coming up through the foundation structure and behind the joinery fittings. Dummy walls can be easily constructed where more room is required or where services originate from above a fixture. 7.5 Service holes up to 100mm square (or round) are permitted through the horizontal T&G wall planks without adversely affecting the structure of the panel, with the exception that holes in TWB’s are positioned no closer than 200mm from a brace edge and provided that holes do not cut through any vertical framing members. Holes that are cut or drilled on site must be sealed by the contractor, using a suitable product, to prevent moisture ingress. 7.6 Other holes up to 19mm in diameter are permitted through timber framing members as provided for in NZS3604: 2011 Clause 8.5.1.6.

Joinery 7.7 Exterior windows and doors are installed in accordance with NZBC E2/AS1, the approved building consent documents, and the manufacturers specific instructions, depending on the type of wall cladding system used.

Fit for Purpose 7.8 In the opinion of Frontier Solid Wood Homes Ltd (Touchwood), based on reference to compliance document, in-service history, experimental testing and existing data, the Touchwood building system is deemed fit for purpose and meets the requirements of the NZBC.
