Ground Floors & Concrete Soffits
The most common construction for solid ground floors in the Netherlands is for spray applied polyurethane foam to be applied directly to the base concrete.
In fact 15K tonnes of foam is used in this application alone. The foam is applied just prior to the screed being laid and It forms a seamless layer with no gaps regardless of intricate details. The depth of foam can easily be adjusted to meet whatever U-value is required and the foam has sufficient compressive strength to withstand design loads.
Typical insulation values achieved are as follows:
| Renotherm Foam Depth | U-value |
|---|---|
| 50mm | 0.22W/m2K |
| 60mm | 0.20W/m2K |
| 80mm | 0.16W/m2K |
Current U-Value requirements and SAP ratings will be achieved more easily with Renotherm
Renotherm is also ideal when spray applied to the underside of concrete soffit ceilings such as is under floor garages and car-parks. The same U-Values as those above are typically achieved which means very little loss to essential ceiling height.
