In a time when the importance of energy efficiency and sustainability in the construction sector is becoming increasingly prominent, thermal insulation of flat roofs is crucial. Buildings are being better insulated to maximize energy efficiency.


For comprehensive roof insulation, it is essential that all components, including roof hatches, have a high insulation value. This ensures optimal insulation of the building envelope.

 

 

Standard RHT Roof Hatch: Top Insulation

Gorter®'s standard roof hatch is designed with a focus on insulation. With a proven high insulation value of Uw ≤ 0.319 W/(m²·K), you not only save on energy costs but also minimize the risk of condensation on the inside of the hatch. Additionally, this fully thermally separated roof hatch construction provides soundproofing and security against break-ins.

 

 

 

Gorter® RHTEP: Extremely Insulated Roof Hatch

For those who aim even higher in energy savings, the Gorter® 'Energy Performance' roof hatch is the ideal choice. This roof hatch excels with a thermal insulation value of Uw ≤ 0.198 W/(m²·K) for the entire roof hatch construction. The RHTEP is perfect for buildings with strict energy efficiency requirements, such as the passive house concept, where comprehensive insulation of the building envelope is essential.

 

 

Glass Roof Hatch RHTG: Natural Daylight and Excellent Insulation

If you are looking for a roof hatch that combines excellent thermal insulation with natural daylight, the Gorter® glass roof hatch is the ultimate solution. This roof hatch features HR+++ triple glazing and, like other Gorter® roof hatches, offers a fully thermally separated construction. The additional heat-reflective layer in the glass ensures a pleasant climate in the space below, and with its standard electric operation, it can also be easily used for ventilation purposes.

 

 

Certification That Stands Strong

All mentioned roof hatches by Gorter® are uniquely certified with a CE marking and a European Technical Assessment (ETA). This certifies and documents the performance of the roof hatches, including thermal insulation, in an irrefutable manner.
