Polyurethane foam, or spray foam is a two-component insulating foam that is installed by a special reactor, either by spraying, injection or casting. Polyurethane foam is formed by the mixing and expanding of two liquid components.
Polyurethane foam is the most efficient insulator today because of its low thermal conductivity and durability. When applied by spraying, the foam adheres directly to the substrate and provides continuous, joint-free insulation and complete air tightness. The insulation stays stable over time, does not sink, shrink or shift.
Polyurethane foam is completely safe for human health. It does not contain volatile particles or emit toxic gases, which ensures a safe and healthy environment for those with allergys. When properly installed, PUR foam will remain inert throughout it's whole lifespan and will not cause harmful emissions. As a bonus, it improves the indoor climate of homes as it does not overgrow, rot or allow various bacteria or fungi to live inside of it. In terms of waste management, polyurethane foams are characterized by minimal waste generation during application.
Closed-cell foam
Closed cell polyurethane foam is a strong insulating material with a density of 33-40kg / m3. Due to its properties and closed cell content, it can be installed a much thinner layer to achieve today's heat resistance norms. Also, closed-cell foam does not require the installation of a vapor barrier or a wind barrier. Closed - sell polyurethane foam is ideal for use on foundations, basements, stone walls, floors, facades, roofs, attics, etc.
Open-cell foam
Open-cell polyurethane foam has a density of 7-12kg / m3 and is lighter and fluffier than closed-cell foam. In terms of thermal insulation, it has a 30% better performance than traditional insulation materials.
Open-cell foam, while blocking any movement of air, still allows the water vapor to pass through it but without collecting it in the insulation layer. This means that insulating with open-cell foam requires the installation of a vapor barrier.
Because of its soft and fluffy structure, open-cell foam is an ideal sound insulator. It is also ideally suited for use in wood constructions as it eliminates the risk of cracking or shrinkage caused by the movements of the wood.
Ideal for use on facades, internal and partition walls, attics, ceilings, floors, etc.
Using polyurethane foam for insulation:
- You save a lot of time - polyurethane foam installation is much faster than it is with traditional insulation materials.
- No material residue - we come with our equipment and materials and leave the workspace clean when we leave
- No need to worry about the sinking, shrinking or shifting of the insulation over time
- No joints in the insulation, which means cold bridges are excluded
- Maximum insulation with minimal layer thickness. Ideal solution in tight conditions
- Easy to install even in difficult places
- Provides significant savings on both winter heating costs and summer cooling costs
