DOLLE clickFIX® Thermo Comfort loft ladder has 70 mm thick polyurethane insulation. Polyurethane has the best insulation value, stability and quality on the market. Therefore, this DOLLE loft ladder achieves the highest insulation value on the market. The U-value is revolutionary low - only 0.38 W/m2*K. At DOLLE, we test our insulation performance - we don't just calculate it. Our loft ladders are tested as building components (not just in the centre). This way, we get the most accurate result because any draughts from the edges are included.
It is possible to design the Made-to-measure loft ladder with a casing height of up to 80 cm. Casing heights over 36 cm are fitted with an extra tread in the casing. If the casing height is above 65 cm, 2 treads must be installed to comply with building regulations. The casing is finished in white primed plywood.
We use the term " ceiling opening ". The term refers to the size of the opening in the ceiling where the loft ladder will be placed.
