The upstand and cover are isolated so that there is no heat lost through the roof hatch when it is closed. Isolation values vary greatly per brand and per type of roof access. Depending on the situation, you can choose a roof access hatch with an average insulation value or a high insulation value.
For example, new manufacturing projects such as hospitals, schools, and apartment complexes often choose the roof access hatch with high insulation values. The insulation value of the roof access hatch mainly depends on the type of isolation used, the thickness of isolation, and thermal separation.

In general, the following practical rules apply to isolation: The thicker the isolation, the higher the isolation value during thermal separation.
When do you need a Roof Access Hatch?
There are several situations where you can use the Roof Access Hatch, which you can usually sort into two categories:
- Non-housing buildings such as hospitals, offices, industrial units, etc.
- Residential building
Roof access hatch for non-housing buildings
Roofing access for non-housing buildings is often installed for the purpose of carrying out maintenance on roof or roof installations, such as air processing systems, air conditioning units, etc., which require access to the roof. Until a few years ago, the locked stairs were used to access the roof, which meant that people had to start a long vertical climb from the ground floor to the roof. Long climbing and limited space at home do not make the ideal way to access the roof. In addition, unauthorized people also use locked upstairs, which results in a number of risks.
Roof access hatches for residential buildings
Roof access hatches for residential buildings serve an entirely different purpose: letting you relax on your rooftop terrace. Access to roof terraces on residential buildings, often apartments, is made easy with roof access hatches. Often, glazed roof access hatches are used to grant access to roof terraces and they let daylight into the room underneath, making the room look more attractive and spacious. Additionally, a glazed roof access hatch provides spacious access and can be easily combined with a fixed staircase.
