Flat roof constructions can either be insulated as warm or cold, the difference being in where the insulation material is placed. As most fall protection anchor points are installed on the roof surface it is important to note the differences between warm and cold roof constructions.
The main difference between both roof types is the location of the insulation with respect to the joists. In a cold roof construction the insulation can be found between the joists, beneath the roof deck. A warm roof construction, on the other hand, has insulation installed on top of the roof deck, covered by a waterproofing membrane.
When installing fall protection on a warm roof construction the layer of insulation and waterproofing membrane have to be penetrated, which will result in a thermal bridge and might even cause leakage. For a cold roof construction the risk of a leak also exists, after all the roof material is being pierced in order to install a fall protection system.
A thermal bridge, or cold bridge, is a ”weak” spot in the insulation where warmth can leak to the outside. This can lead to higher costs for heating the building.
As the thermal bridge is the coldest part on the inside of the roof, a side effect can be local condensation. This can cause corrosion and rotting of the surrounding materials, resulting in higher costs for maintenance.
At XSPlatforms we are aware of the thermal bridge effect and have done everything to prevent this side effect. As a result we have developed our XSBase plate, which only requires one drilling hole, reducing the amount of thermal bridges compared with other anchors.
