2 You ll find a reliable partner in NBT and its solutions for the building envelope.

3 NBT are a leading distributor of thermal performance products and solutions that provide; thermal, moisture, acoustic and overheating control. Our specification support helps you ensure the right product specification on a given building type. Successfully used on thousands of UK-based projects; NBT solutions are tried, tested and trusted by house builders, commercial developers, housing associations and local authorities. 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 ensure that significant problems are not created. Breathability Over 11 1 / 2 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. 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. Pavatex has thermal mass which soaks up the heat from the sun helping to prevent summertime overheating.
