Weather resistant sealing band forming e.g. under-tile roofing felt on pitched roof |
摘要 |
A weather sealing band used in building construction, especially on pitched roofs as an under-tile roofing felt, is novel in comprising a polyamide sheet. Its mean vapour diffusion resistance is expressed as an air layer equivalent diffusion thickness of 0.1- 0.5 m. Preferably the actual sheet thickness is 20-250 mu m, especially 50-150 mu m. The polyamide is PA6 or PA6.6. It is thermally stabilised and may be mixed with a copolymer. UV stabilisation is included, together with fibre reinforcement.
