Retrofit Insulation Systems for Old Buildings with New Timber Frame Extension

In the UK, 1 in 4 of our homes are pre-1919 'solid' wall construction. In the drive towards energy efficiency and carbon savings, we are all being encouraged to

insulate our homes but care must be taken with older buildings as they need to maintain vapour permeability, i.e. to manage moisture, therefore any insulation

solution must also be vapour permeable to avoid the problems that we now know are associated with trapped moisture.

 At Tŷ-Mawr we have developed a number of systems using environmentally-friendly materials that both respect and support the nature of these buildings as 

well as the planet. The systems are now all registered with Local Authority Building Control.
