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.

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.


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.

Additional Benefits

Fire Protection

PAVATEX prevents overheating in case of fire

Homeowners need to consider the worst-case scenario: the building catching fire. They need to be prepared for what should never happen in order to protect residents and the building as best they can. House fires can even generate temperatures of more than 1,000° C.

Noise Control

PAVATEX protects against noise

Noise is not only bothersome, but also poses a risk to health. In cities in particular, people are exposed to sources of noise on a continuous basis. If you can’t get away from this noise even in your own home, this can result in serious health problems. It is therefore well worth protecting your home accordingly.
