Wall Insulation: Sprayed Polyurethane Foam Interior and Exterior
Optimize the energy efficiency of your home by insulating your walls with our sprayed polyurethane foam. Whether for interior or exterior, wall insulation by sprayed foam is a high-performance solution to improve thermal efficiency and reduce energy losses. Thanks to its ability to fill the smallest gaps, sprayed polyurethane foam wall offers a uniform and durable thermal barrier, eliminating thermal bridges for maximum energy performance.
Why choose sprayed polyurethane foam for wall insulation? High thermal performance: Low thermal conductivity for maximum insulation. Air tightness: Eliminates thermal bridges and air infiltration. Rapid application: Allows insulation of large surfaces in reduced time. Versatility: Suitable for both interior and exterior wall spray insulation. Durability: The foam retains its insulating properties for decades, offering a durable and high-performance insulation solution.
Interior wall insulation by sprayed foam consisting of applying foam directly to the interior wall. Ideal method for renovations or spaces requiring rapid and effective insulation. Optimal thermal and acoustic insulation, reduction of energy losses, suitable for old houses. Sprayed wall insulation price between €20 and €50/m² depending on technique and material.
Exterior spray insulation using polyurethane foam applied to the exterior facade, before installing a protective or decorative coating. Eliminates thermal bridges, preserves interior space, and strengthens overall building waterproofing. High-performance solution to improve energy efficiency and reduce energy losses.
Cavity wall polyurethane foam injection to insulate already constructed walls by injecting foam into existing cavities. Rapid and non-invasive solution, insulation improvement without major work. Price between €15 and €30/m² for wall injection. Allows effective insulation while preserving interior space and aesthetics.
Interior wall spray insulation preserves exterior space and is ideal for renovations. Exterior wall spray insulation better eliminates thermal bridges and preserves interior space. Both solutions offer excellent thermal performance with low thermal conductivity, optimal air tightness, and increased durability for decades.

Wall Insulation FAQ
What are the advantages of wall insulation by sprayed foam?
Between €20 and €50/m², depending on the technique and material used. Sprayed polyurethane foam insulation is generally in this range, with variations depending on accessibility, necessary thickness, and surface complexity. Financial aid such as MaPrimeRénov' can significantly reduce this cost.
Yes, cavity wall polyurethane foam injection allows effective insulation without major work. This technique involves injecting foam into existing cavities of cavity walls, creating a continuous thermal barrier and eliminating thermal bridges, while preserving interior space and the aesthetics of your home.
Indirectly, because it reduces your heating and air conditioning needs, thus reducing your carbon footprint. Sprayed polyurethane foam offers high-performance insulation that significantly reduces energy consumption, thus contributing to environmental protection and energy efficiency compliant with RT 2012.
Interior wall spray insulation preserves exterior space and is ideal for renovations, while exterior wall spray insulation better eliminates thermal bridges and preserves interior space. Both solutions offer excellent thermal performance, the choice depends on your configuration and specific energy efficiency needs.
It is possible to insulate walls with polyurethane foam yourself using kits available in stores, but for optimal application compliant with standards, it is strongly recommended to call on certified professionals. Poor application can reduce the durability and effectiveness of insulation.
The necessary thickness depends on several factors: the thermal conductivity of the foam, the desired thermal resistance (R), and current standards. In general, for effective wall insulation, a thickness of 10 to 15 cm of sprayed polyurethane foam is recommended to achieve optimal energy performance and meet RT 2012 requirements.
