Foam Adhesives

Our foam adhesives provide a high-strength, reliable bonding solution for insulation board installation and a wide range of common building materials. Using PU adhesive foam is quicker and more efficient than traditional mortar-based methods, helping professionals complete work faster while maintaining exceptional bond performance.

Foam adhesives that deliver strong, fast bonding on every project

Foam adhesives are versatile fixing products that expand slightly to fill gaps, ensuring a secure hold even on uneven surfaces. With excellent adhesion to materials such as concrete, plaster, stone, wood, steel, bricks and plasterboard, they are widely used in construction and finishing applications.

What foam adhesives are and how PU adhesive foam performs on site

PU adhesive foam (polyurethane-based) is a single component product that cures using moisture in the air. Once cured, it forms a durable, rot proof bond that withstands movement, weather exposure and long-term use. The foam structure also contributes to improved airtightness and rigidity across the fixing area.

Why polyurethane adhesive offers a more efficient installation method

Polyurethane adhesive is increasingly chosen in EWI and dry lining systems thanks to its speed, ease of applying and reduced mess compared with traditional adhesives. It also helps minimise thermal bridging, making it ideal for insulation installations.

Stronger grip on uneven or porous surfaces

PU adhesive foam works exceptionally well on rough and porous surfaces because it can expand slightly into small voids and textures, creating a more complete bond.

Shorter installation time and reduced labour costs

Fast grab and fast curing abilities help reduce overall installation time, allowing installers to progress with board fixing and finishing stages sooner.

Where adhesive foam is used across EWI and construction applications

Adhesive foam is designed for bonding:

• EPS and polystyrene insulation boards.
• Rockwool and mineral insulation products.
• Lightweight cladding elements and façade accessories.
• Dry lining and plasterboard systems.
• Decorative panels on mdf, timber, chipboard and laminate.

It is also compatible with metal, aluminium, zinc, ceramics, painted substrates and some bitumen surfaces — always check specific product details prior to installation.

How to select the right foam adhesive for your substrate and conditions

When choosing foam adhesives, consider:

• Material type — e.g. lightweight insulation, wood, steel, stone.
• Site environment — temperature, humidity and moisture levels.
• Application speed and ease required.
• Whether the area requires movement protection or flexible bonds.

Most options are easy to use by hand with a foam gun, allowing adhesive to be applied in a neat, continuous bead.

Performance factors that influence curing and long-term durability

To ensure lasting results, always place boards accurately and check for full coverage — especially when working with uneven surfaces. Allow the correct curing time and avoid disturbing elements until the bond has fully set.

For best performance:

• Cut foam overflow once hardened.
• Keep surfaces clean and free from loose dust.
• Follow manufacturer guidance on temperature and substrate suitability.
