ExternalRendering

Thermal insulation mortar:

Special renders/plasters for the thermal insulation of buildings

Have a high content of thermally insulating light-weightcomponents

Expanded Poly Styrene (EPS)

Mineral foam glass (e.g. based on perlite / recycled glass)

Have very low thermal conductivity and a thickness of 20 100mm

Thermal insulation mortars systems are:

Composed of aligned heat-insulating base renders and water-repellent top renders / top coats

Top coats also serve to protect the system from mechanicaldamage and weathering

THERMAL INSULATION SYSTEMS ARE ALSO USED FORCOMPLEX ARCHITECTURAL STRUCTURES

Exterior insulation for highly complex

architectural structures:

Highly structured facades

(curvatures, profiles)

Mixed brickwork

Preservation of valuable historicalarchitecture (e.g. timbered buildingswith infilling)

THERMAL CONDUCTIVITY, THERMAL-TRANSFERRESISTANCE AND U-VALUE

Thermal conductivity: ; W/m.K

describe how much heat energy passes through one square meter of barrier when the

temperature differences between the 2 sides is 1C/ meter

Thermal-transfer resistance: Rx = dx / x ; m2.K/W

is calculated by dividing the thickness of the barrier by the thermal conductivity

various transfer-resistance values can be added: Rtotal = Rai + R1 + R2 ++ Rn + Rao

U-Value (Heat transfer): U = 1 / Rtotal ; W/ m2.K

is the heat transfer and describes the amount of energy lost per square meter for athermal barrier at a 1C temperature difference between inside and outside

The lower the U-Value, more energy can be saved!

APPLICATIONREGULATION AND RECOMMENDATIONS

Application with machines or manual (5-6 cm/working

step)

Drying time for TIM: 1 day per 5 mm thickness, but at

least 7days

Drying time for patching mortar: 1 day per 1 mmthickness, but at least 6 days

If humidity is high or temperatures low: drying times

have to be extended

The substrate has to be dry, dust-free, free of loosematerial and its temperature should be above 5 C.

In certain cases primer or plaster base (>5cm) are

essential/recommended

Crack delicate area (edges, openings) can beprotected by a fiber mesh

Dark colors for the finish coat should be avoided (hightemperatures -> shear stress)
