Data Sheets
Cromar Protect 1F is a Non Vapour Permeable (non-breather) membrane tailored for application beneath slating and tiled pitched roofs. This is specifically designed to be bat friendly and recommended for roofs where bats are known to roost. It serves as a high-performance underlay necessitating ventilation according to BS5250 2021 standards. Installation aligns with BS5534 2018 guidelines. This membrane effectively blocks the intrusion of dust, rain, and snow into the roof void, serving as a secondary barrier. When correctly installed, it offers temporary protection for up to 3 months until the primary barrier (slates/tiles) is in place. The lightweight material is easy to handle, and its 45m x 1m roll size facilitates convenient handling.
