This brochure contains over 900 individual u-value calculations

for most common masonry wall types using the Thomas

Armstrong group’s range of concrete blocks. Although by no

means exhaustive, this set of data aims to provide solutions to

achieving a range of u-values in most scenarios.

The target u-values contained here encompass both current and

likely future requirements imposed by the Building Regulations

including zero carbon homes.

Calculations are made in good faith and are based upon the dataprovided by insulation manufacturers at the time. However, such datais liable to change without prior notice from the manufacturer and werecommend that verification calculations are carried out at the designstage based upon the very latest available data.

The calculations shown here are intended for indicative use only andThomas Armstrong Limited and its associated companies cannot beheld liable for any incidental or consequential damage or loss arisingfrom the use of this data.

We are full members of both of the UK’s leading industry associations; the

Concrete Block Association (CBA) and the Aircrete Products Association

British Precast.

Each table shows two alternative methods for achieving

the target u-value for each block type used. However,

there will be alternative options available with other

insulation types and for specific u-value calculations,

please contact our Technical Department. The

information contained here is designed to offer the

most economical solutions, keeping cavity widths to a

Reference Table of Our Block Types

† Higher strengths are available to order

Insulite Lightweight BlocksThe vast majority of raw material used in ourlightweight concrete blocks is fully recycled.In fact 90 ‐ 95% by weight of the block con‐sists of recycled material, predominantly FBA(furnace bo�om ash) from coal‐fired powersta�ons which would otherwise be landfilled.

Dense Concrete BlocksBy their nature, dense concrete blocks re‐quire a propor�on of quarried sand andgravel in order to achieve the desired tough‐ness, strength and density characteris�cs.We con�nually strive to u�lize as much recy‐cled material as possible and in fact the recy‐cled content of these blocks is around 20-25% (glass sand and reclaimed aggregates).

Airtec Aerated Concrete ProductsUp to 90% of all raw materials used in themanufacture of our Airtec products is recy‐cled material. Furthermore, Airtec is manu‐factured in the UK’s most advanced aeratedproduct facility u�lizing unique low-energyequipment. We re-use excess energy fromthe curing process throughout the site; noth‐ing is wasted.

Our Products

As a company policy we are constantlystriving to use as much recycled materialas possible which is o�en dependent onthe availability of materials, loca�on ofthe source and their effect on the qualityof the blocks.

The majority of our products are manufac‐tured under the interna�onally recog‐nized system ISO 14001 EnvironmentalManagement. We are fully commi�ed tocer�fying all of our sites to this standard.
