Why Choose Supex 100 expanding pu foam Over Ordinary Foams

Ordinary expanding pu foams shrink or sag on vertical surfaces. Supex 100 resists both issues. It bonds strongly to concrete, wood, metal, and uPVC. As a result, your seals last for years.

You gain excellent thermal insulation with a factor of 0.030 W/m.K. Soundproofing reaches up to 60 dB. Consequently, rooms stay quieter and cooler. You cut energy costs and block dust, insects, and moisture effectively.

The valve never sticks or blocks. You reuse the can smoothly. Moreover, the semi-flexible cured foam shapes easily by hand. You often skip cutting altogether.

Supex 100 expanding pu foam sealant delivers standout performance. Here are the top benefits:

• Strong adhesion bonds to most building materials instantly.

• Fast curing – tack-free in 10–12 minutes, cuttable in 15–30 minutes.
• Full cure completes in 12–24 hours.
• Low-temperature application works down to +5°C.
