The GL251 lockable drop down loft door is an innovative solution to the need for energy efficient loft space access for use in shared accommodation, offering a cost effective alternative to traditional means of access. The unobtrusive design coupled with sleek, contemporary styling makes the door an ideal match for modern decors. It is supplied with a key lock for additional security. The revolutionary design of the multi-point catch mechanism means that the GL251 door can maintain a more effective draught seal around the entire accessible opening, helping to meet the air leakage requirements of Part L of the Building Regulations and preventing the problem of moist warm air entering the roof space causing condensation and heat loss issues.
