High strength wooden loft ladder with insulated and airtight hatch box. Available Passivhaus (Passive House) certified.
Loft applications.
The Designo wooden loft ladder perfectly balances aesthetics with strength and quality. Available as a certified Passivhaus loft ladder (by the Passivhaus Institute).
The three-part folding heavy-duty wooden loft ladder is contained within, and attached to, an insulated wooden hatch box. It offers excellent energy efficiency (0.60 W/m²K) thanks to a highly insulated trapdoor with six-point locking mechanism providing a Class 4 certified airtight seal.
It is also fitted with the patented WDL sealing and insulation tape, which provides a perfect seal between the hatch box and building and saves time during installation.
