High strength and highly insulated wooden loft ladder.
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.
