Why Choose PUR Foam for Building Insulation?
PUR foam, or polyurethane foam, is one of the most effective and durable insulation materials used in both new builds and renovation projects. Thanks to its high thermal insulation capacity, airtightness, and moisture resistance, PUR insulation helps to:
- Reduce heat loss and save on heating costs.
- Keep the structure dry and free from mould.
- Fill even the smallest cracks and surface irregularities, creating a seamless insulation layer.
Spray-applied PUR foam adheres exceptionally well to concrete, wood, metal, and other surfaces, eliminating cold bridges, which are often a problem with traditional board insulation materials.

How Is PUR Foam Installed?
1. Preparation
- Clean the surface of dust, oil, and loose particles.
- Dry the substrate if necessary, as moisture reduces foam adhesion.
- Isolate the work area to protect surroundings from overspray.
2. Applying PUR Foam
- Use two-component PUR foam, mixed during spraying with a specialised high-pressure machine.
- The foam expands immediately and bonds to the substrate.
- Recommended insulation thickness is 10–15 cm, depending on energy efficiency requirements.
3. Adding a Protective Layer
Since PUR foam is not UV-resistant, it should be covered with soil, plaster, or other finishing materials.
A protective layer also helps prevent mechanical damage.
Important Tips for PUR Foam Insulation
- Hire a certified installer – quality depends on the correct mixing ratio and even application.
- Ensure good ventilation during and after installation, as chemical vapours are released when applying the foam.
- Make sure all surfaces are properly prepared for maximum adhesion and durability.
Why Is PUR Foam the Best Thermal Insulation Material?
- High R-value – excellent thermal insulation even with a thin layer.
- Long-lasting durability – properly installed PUR insulation can last for decades.
- Complete elimination of cold bridges – thanks to its monolithic, seamless layer.
PUR foam is a fast, effective, and long-lasting solution suitable for insulating both residential and commercial buildings.
