The Designo DD wooden loft ladder perfectly balances aesthetics with strength, quality and excellent energy efficiency. The 3-part folding heavy duty wooden loft ladder is contained within, and attached to, a highly insulated wooden hatch box with a secondary upper cover. The upper cover can be closed immediately after entering the loft, therefore preventing the flow of air. This not only helps to lock the warmth in the home or building, but also prevents moist air from flowing into the loft and condensing in the cold areas. The highly insulated lower trapdoor with 6-point locking mechanism providing an airtight seal.
The Desigo DD loft ladder 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.
