Summary

As fuel prices rise, fossil fuel supplies become more unpredictable and we strive to reduce our CO2 emissions, every Watt saved now counts.

This Wood Information Sheet (WIS) outlines the options for improving the thermal performance of existing timber frame buildings and summarises the important issues that specifiers should consider when implementing improvements.

Key Information

Ever thighter building regulations are increasing thermal standards, the focus being on reducing CO2 emissions.

Viable options for upgrading wall insulation has not generally been justifiable, financially, except when done with substantial renovations.

Whenever insulation is upgraded, it is important to avoid creating circumstances where interstitial condensation may occur. This could lead to timber decay.

Case studies

The GlaxoSmithKline (GSK) Carbon Neutral Laboratory for Sustainable Chemistry was designed as an exemplar of sustainability in design, construction and choice of materials, and one which would be carbon neutral over its 25 year lifetime.

The building is organised as a two storey rendered block, containing the students union and associated facilities, interlocking with a four storey timber clad block, housing teaching and administration space.
