The Supreme DD is a very highly insulated version of the popular Supreme retractable aluminium loft ladder, achieving a U-value of just 0.28 W/m2K. The Supreme DD is supplied as a ready to fit unit, manufactured from high strength die-cast aluminium alloy components contained within, and attached to, a specially insulated hatch box with an upper cover that 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 Supreme DD’s heavy duty spring mechanism allows you to raise and lower the ladder with a minimum of effort (operating force of less than 3kg). Large steps and pre-assembled telescopic handrail offer comfort, safety and ease of egress.
