Cavity Walls<br />

•<strong>Aircrete</strong> <strong>Aircrete</strong> blocks are used extensively in<br />

construction <strong>for</strong> :- :-<br />

–Structural Structural support<br />

–Thermal Thermal insulation<br />

•Low Low Density (Solar) blocks are ideal <strong>for</strong><br />

clear cavity solutions<br />

•Medium Medium Density (Standard) is used in<br />

partial or fully filled constructions.<br />

•See See technical literature <strong>for</strong> solutions<br />

Solar - Ideal <strong>for</strong> clear cavity solutions because <strong>of</strong><br />

thermal properties <strong>of</strong> blocks. This is further enhanced if<br />

Solar is used in both leaves <strong>of</strong> the wall.<br />

E.g. Brick Outer-50mm cavity-115mm Solar-27mm<br />

Thermalboard plus = 0.45W/mK 2<br />

or<br />

16mm render-115 Solar-50mm cavity-115mm Solar-9.5<br />

Plasterboard on dabs = 0.43W/mK 2<br />

Standard - Thickness <strong>of</strong> insulation can be reduced when<br />

using Standard compared to dense aggregate blocks.<br />

NB: Clear cavity is possible with Standard if thermal<br />

board lining is used<br />

U-values are contained in the Celcon “Book <strong>of</strong> <strong>Blocks</strong>”<br />
