Popular Fischer Products

Fischer's expanding foam range typically includes standard PU foam for general-purpose gap filling and insulation, ideal for window and door installation. Their fire-rated foam meets Building Regulations requirements for sealing service penetrations and maintaining fire barriers. For external applications, Fischer offers weather-resistant formulations with enhanced UV stability, preventing degradation and discolouration over time. Professional tradesmen particularly value Fischer's gun-grade foams, which provide precise control and reduced waste on larger projects.

Frequently Asked Questions

What's the difference between gun-grade and hand-held Fischer foam?

Gun-grade foam requires a professional foam gun applicator, offering superior control, reusability, and reduced waste—ideal for installers and regular users. Hand-held foam comes with an attached straw applicator, perfect for one-off jobs or emergency repairs, though typically at a higher cost per application.

How long does Fischer expanding foam take to cure?

Fischer foam typically becomes tack-free within 20-30 minutes and can be trimmed after approximately 1 hour. Full cure depends on foam depth and ambient conditions but generally occurs within 24 hours. Thicker applications may require longer curing times.

Can Fischer expanding foam be used externally?

Yes, Fischer expanding foam can be used externally, but it must be protected from direct UV exposure once cured. Trim excess foam flush and cover with paint, render, or sealant to prevent degradation and maintain weatherproofing performance.
