We use wood fibre insulation . Apart from the obvious environmental benefits wood fibre has 3 obvious benefits. **CHANGE**
1) Overheating
Low level heat is needed to raise the internal temperature in winter. Insulation keeps this heat in. The sun produces high level heat which can lead to overheating in the summer. Conventional insulation, in structures such as roofs and timber frame buildings, can’t keep high level heat out.
Wood fibre insulation has thermal mass which ‘soaks up’ the heat from the sun helping to prevent summertime overheating.
2) Thermal performance
Good thermal performance is now prerequisite to any new build or renovation. However, breathability and overheating control must also be considered simultaneously to protect the integrity of the building fabric and insure that significant problems are not created.
3) Breathability
Over 11½ litres of moisture are produced internally by the average household each day. The external shell of a building is much like a coat, it needs to keep the rain off, but like a GORE-TEX® jacket, it must not allow moisture, produced internally, to get trapped within the building fabric. It must let it out. Pavatex® is the GORE-TEX® of buildings.
