Soudal FLEXIFOAM All Season Installation Foam 750ml High Elasticity 50% Blue B2 Rated

Product Overview

Soudal Flexifoam All Season gun-applied installation and sealing foam is engineered for thermal insulation and airtight sealing in a range of construction settings, including residential, commercial, and modular builds. With a polyurethane prepolymer base and B2 fire classification (DIN 4102), its performance is validated by multiple European standards, ensuring high levels of energy efficiency and acoustic dampening for professional applications. Its elasticity accommodates dimensional variation and joint movement, making it suitable for environments subject to temperature and humidity fluctuations.

What distinguishes this SKU is its dimensional elastic deformation capacity up to 50% without loss of material structure, far exceeding standard foams limited to 10%. This flexibility is crucial for installers addressing structural movement in timber buildings, frame constructions, and large-format joinery, reducing risk of sealing failure and minimizing maintenance costs. Particularly recommended for contractors managing window, door, and utility penetrations in environments where movement, vibration, or seasonal change are significant.

Key Features

• High elastic deformation ? maintains stability up to 50% dimensional movement, compared to 10% for standard PU foams


• Acoustic insulation Rstw=63 dB (EN ISO 717-1) ? effective sound dampening for partition walls, staircases, and utility penetrations


• Low secondary expansion and shrinkage <5% (FEICA TM 1004) ? preserves long-term integrity in dynamic joints


• All-season application ? sticks and cures at temperatures from -10°C to +35°C, for winter and summer use


• Water absorption <1 kg/m? (PN-EN 1609:2013) ? reduces risk of moisture penetration in exterior applications


• Thermal conductivity 34.5 mW/m?K (DIN 52612) ? supports energy-saving envelope design


• Distinctive blue color ? enables quick visual verification in multi-trade installation environments

Applications

Applied for sealing and insulating joints in window and door installations (PVC, aluminium, wood), large-format joinery (PSK, HST), cable and pipe penetrations, and partition walls in residential and commercial buildings. Suitable for timber structures, modular builds, and environments subject to vibration, mechanical stress, or thermal expansion, such as staircases and lofts. Meets requirements for projects needing acoustic insulation, air-tightness, all-season installation, and B2 fire-rated materials.
