About Loft Access Doors
The Timloc range presents quality, loft hatches and access doors in clean simple designs that are not just easy to install and operate, but offer other features that are essential to today’s buildings, such as:
- Managed heat and air leakage
- Condensation and draught control
- Choice of insulation material performance
There’s also a choice of:
- Fire-rated or non fire-rated loft access
- Closing and locking mechanisms
All our loft access hatches and doors meet the requirements of Building Regulation Part L (England and Wales), Building Regulation Part E (Northern Ireland) and Scottish Building Standards for air tightness. Products that comply with Robust Details, 0.35 and 0.25 U value versions are also available.
The performance of loft access hatches impact the building so much that the installations into new build residential and commercial buildings have to meet specific mandatory performance regulations and standards
