With the Energy Performance roof hatch, Gorter continues the success of its entirely, thermally separated roof hatches. This roof hatch has an exceptional insulation value, with an insulation value of Uw ≤ 0,198 W/(m².K) for the entire roof hatch construction.
The new Gorter® WAEI Fire rated floor door was tested by Efectis in December 2016 according to European EN 1634-1:2014 standard. The test established that the hinged steel floor door is Fire rated for 120 minutes and amply meets the required standard.
The success of the Gorter glazed roof hatches continues following the launch of the new RHTG roof hatch fitted with triple insulating glass known as triple glazing. Glazed roof hatches are often used to access roof terraces and roof gardens and, in this new type of glazing complemented by yet another size option, they offer even more advantages!
