Innovative GL250 loft access door. The multi-point catch mechanism maintains a more effective draught seal, helping to meet the air leakage requirements of the Part L Building Regulations.
Description & Key Features
The GL250 drop down loft door is an innovative solution to the need for energy efficient loft space access, offering a cost effective alternative to traditional roof space entry. The unobtrusive design coupled with sleek, contemporary styling makes the door an ideal match for modern decors.
