Loft applications.
Roof access applications.
Compact concertina aluminium loft ladder, specially designed for small ceiling openings.
It is supplied as a ready to fit unit, consisting of a space-saving retractable ladder contained within, and attached to, a laminated wooden hatch box. The insulated trapdoor offers good energy efficiency (0.77 W/m²K) thanks to a highly insulated trapdoor with four-point locking mechanism providing a Class 4 certified airtight seal. Both sides of the trapdoor are finished in white for improved aesthetics. It is also fitted with the patented WDL sealing and insulation tap, which provides a perfect seal between the hatch box and building and saves time during installation.
Can be specified with a weather resistant upper hatch for flat roof access (maximum ceiling/ roof structure thickness of 710 mm).
