Addressing the climate impact of foam insulation

A polyurethane foam technology pioneer

Recognizing the need for a more durable and healthier environment for future generations, Soudal focuses on R&D and technical support, aiming its products and product development to the highest health and safety standards.

By focusing on sustainable raw materials and safe handling, Soudal plans to achieve climate neutrality. This new platform of foams has the same or even better quality and properties as the classic technology, allowing customers to seamlessly integrate them into their existing operations without loss of quality whilst supporting their aim to reach their climate protection goals.

Most durable blowing agent

Soudal was the first European company offering a complete commercial product line of closed-cell foam systems based on the 4th generation blowing agent technology, called H(C)FO. H(C)FO-based formulations guarantee a near to zero global warming potential (GWP) as well as a zero ozone depletion potential (ODP). Soudal managed to produce Soudafoam H(C)FO-blown PU systems that give a lowest possible density closed cell foam at peak performing mechanical strength and thermal insulation properties. Besides that, these foams add structural strength and an air- and water tight seamless foam layer.

Water based technology as a blowing agent

Based on an inherent natural resource, open-cell water blown systems provide a flexible and lightweight, water vapor open seamless foam layer with thermal and acoustic insulation properties.

Bio based Polyols

Soudal’s portfolio of open- and closed cell 2 component polyurethane systems all carry a polyol component that contains up to 66% bio-content, aiming to limit the use of fossil-oil based raw materials to the highest extent possible. The company’s Environmental Product Declaration (EPD) uses life-cycle analysis to assess the environmental impact of buildings and serves as a benchmark for Soudal’s environmental stewardship.

Recycled content

All Soudal two component polyurethane foam systems strive to incorporate a maximum amount of recycled content within its product whilst maintaining the highest performance parameters. Over 30% of recycled resources are used in both closed cell and open-cell systems.

Lowest emission

Soudal’s low pressure polyurethane systems generate negligible to zero isocyanate emission, which makes the systems compliant to and exempt from future REACH restrictions and regulations.

Bio based MDI

Soudal incorporates a bio-attributed methylene diphenyl diisocyanate (MDI) in its production process. The sustainability aspect lies in the mathematical assignment of plant-based feedstocks to MDI through mass balancing (ISCC PLUS standard), resulting in a significant reduction in carbon footprint compared to fossil-derived counterparts. This choice of raw materials is in line with the principles of the European Green Deal, Fit for 55, and the overarching goal of achieving carbon neutrality in the building sector by 2050.

Contact free working

All Soudal low pressure polyurethane systems are supplied in closed systems, without pumps or vaporization on the vessels and without open vessels. This avoid any operator contact with residual chemicals.
