Book Description

This Special Digest describes timber-frame wall construction solutions that are capable of achieving very high insulation levels using existing technologies; in some cases, wall U-values as low as 0.13 W/m2K are achieved. Timber-frame insulation solutions lend themselves to going significantly beyond the thermal performance requirements of current building regulations, with the potential to address the future aim of zero-carbon housing. This Digest is written for all those involved in specifying or assessing designs, including timber-frame manufacturers, designers, architects and housebuilders.
