Timloc insulated loft doors provide quick and easy to loft space from a ceiling in areas where there may not be that much floor space. The anti-draught loft doors are designed to prevent condensation build up and uplift, with a vapour and condensation migration seal and twist catches to secure the loft door in place. This clean and simply designed Timloc insulated loft door is white in colour but it can be painted to match the aesthetics of a room or to be disguised even further. This loft door will fit neatly between 38mm thick trussed rafters as well as 600mm spaced ceiling joists. Tested by the BRE to ensure it meets Building Regulations Part L, this insulated loft door offers 0.82 U-Value. The extended opening key needs to be bought separately.
