Description

The RHT roof hatches with fixed stairs feature a strong and patented construction. Due to several modifications, the roof hatch is even more resistant against unexpected extreme loads, both during construction and in general use.

Proven insulation performance of the complete roof hatch

With the RHT roof hatch, the insulation value is calculated for the entire construction (Uw), not just the insulation material. The proven insulation performance of the complete hatch is Uw ≤ 0.276 W/(m²·K).
