Puretan 50: asbestos remediation
Puretan 50 is a polyurethane system for construction applications that provides waterproofing and insulation at the same time. It forms a continuous coating, applied to the required thickness by spraying on site with high-technology equipment.
The product is mainly applied for polyurethane foam over-roofing, asbestos encapsulation, asbestos-cement products and Eternit remediation. In these contexts, a layer of spray-applied polyurethane foam makes it possible to treat the roof while helping to encapsulate the material.
Puretan 50 is suitable for applications requiring waterproofing, insulation and continuous surface protection, particularly on roofs and products exposed to weathering.
Main benefits
- Consolidates the surface, improving walkability and the mechanical strength of the sheets.
- Allows rapid intervention with limited disruption to working activities.
- Encapsulates asbestos cement by embedding the fibres in the polyurethane foam layer applied to the roof.
- Produces no toxic or hazardous waste and does not require the sheets to be washed.
- Thermally insulating and waterproof product.
- Provides continuous waterproofing and thermal-acoustic insulation.
- Good compressive and tensile strength.
- Rapid application.
- Long-term durability.
- Eliminates thermal bridges through seamless application.
- High vapour permeability.
- Adapts to any shape of substrate.
- Easy application around downpipes, rooflights, vents and junctions with vertical walls.
- Excellent adhesion to materials including iron, concrete, brick, fibre cement, wood, bitumen, glass and fibreglass.
- Resistant to acids, solvents and hydrocarbons.
- Resistant to marine and industrial atmospheres.
- Resistant to fungi and microorganisms.
- Can be easily restored and repaired after accidental damage.
