Gorter® Flat Roof Access Hatch RHT with Ladder

Gorter® Flat Roof Access Hatch RHT with Ladder

Gorter roof hatches with ladders provide practical and safe access to flat roofs for maintenance work as well as access to cooling installations, lift machine rooms, window cleaning installations, solar collectors, and other facilities on rooftops. Roof hatches can be installed on flat roofs with a maximum slope of 30°.

Extension ladder
Depending on the floor height, the Gorter combination of roof hatch and ladder is available with a single, double or triple extension ladder. The Gorter ladder is supplied as standard with suspension brackets for safe storage when the ladder is not in use. This combination is ideal for infrequent use of the roof hatch. For more frequent use, we recommend a roof hatch with scissor stairs or fixed staircase.

New generation Gorter RHT roof hatch
The new generation RHT roof hatches feature an extremely strong and patented construction. Thanks to several modifications, the roof hatch is even more resistant against unexpected extreme loads, both during construction and in general use.

Improved features and functionalities of the indestructible and sustainable RHT roof hatch:

Made and Designed in Holland
New and improved, patented indestructible construction
Trusted, with CE(ETA) certification
Fully standardised to metric dimensioning

Fully thermally broken
The Gorter RHT roof hatch has a fully thermally broken curb and cover, and a proven high insulation value of U_w ≤ 0.276 W/(m².K) This minimises the chance of condensation forming and guarantees energy cost savings.
