Polyurethane foam system
External thermal insulation
Polyurethane is a material we encounter everywhere in our daily lives. It is a highly versatile material and is the result of the chemical combination of isocyanate and polyol. Particularly in the construction sector, where thermal insulation and soundproofing are required, polyurethane foam is the ideal material and can deliver excellent results with high performance. It has no joints, which eliminates thermal bridges and significantly reduces the cooling and heating costs of buildings. It also has the lowest thermal conductivity coefficient compared to all other insulation materials.
1. Surface preparation to the required extent (cleaning, washing, local repairs, removal of loose parts, etc.)
2. Preparation of materials by preheating and stirring according to the supplier's technical data sheets.
3. The spraying process of the foam begins, during which continuous monitoring of essential parameters (temperature, pressure, material flow, etc.) is carried out to ensure proper application. It should be noted that the foam does not require a primer beforehand, as like all polyurethane materials, it has exceptionally strong adhesive properties.
4. Once the application is complete, a quality inspection is carried out using specialized equipment to detect any imperfections or problematic areas, which are then repaired.
5. If the applied material requires a final protective layer for this specific application, an appropriate material is applied.
Advantages of polyurethane foam:
The biggest advantages of using polyurethane foam are the speed of application, as most materials cure up to 80% in 20-30 seconds and can withstand traffic and rain after just a few minutes (15-30). It has faster reaction, application, and curing times compared to any other technology, allowing work to be completed very quickly (for example, thermal insulation of 400m² can be done in one day).
It is applied in 2-3 layers to the required thickness, creating a seamless surface without joints or seams, which are the main points where conventional materials tend to fail.
It can be applied to any surface, regardless of shape or difficulty of access, including protrusions or cavities.
When combined with hot spray-applied polyurea, it can quickly provide a top-tier thermal and waterproofing system, and it also has soundproofing properties.
It is an environmentally friendly product.
After the application of polyurethane foam, polyurea can be applied.
