Find out moreConstructed from injection-moulded polypropylene under BS EN ISO 9001 and designed to open with a push-up motion, Glidevale AH4 loft hatches comply with the loft hatch specifications set out in Building Regulations Approved Documents L and C. As a result, they are certified to deliver superior performance.
Equipped with a complete loft hatch system that effectively seals to the ceiling, the hatch is thermally insulated and maintains loft or ceiling insulation, in turn reducing heat loss. Furthermore, the seals in the system help to minimise the chance of condensation by limiting the amount of water vapour migration.
Both domestic and commercial buildings benefit from the twin latches and anti-wind uplift mechanism that provide protection for both the hatch and the items stored in the loft space.
Please note:
Question:
I currently have a Glidevale LA1 Loft hatch is the AH4 the new equivalent in relation to size.
Answer:
As long as the dimensions match it should be ok, however, I can't say if it's a direct replacement
Question:
what are the external dimensions i.e. frame length and width?
Answer:
Trimmed Opening Size: 717mm x 555mm
Accessible Clearance Opening: 680mm x 520mm
Question:
I have previously had a Manthorpe loft hatch the opening has been cut to 550 x 720. I need a push up hatch would the AH4 be a suitable replacement or is it too small. Thanks
Answer:
The AH4 is to suit a trimmed opening size of 717mm x 555mm so is pretty close to the opening you have, may just need a little adjustment on installation.
