IQ PU Foam
SKU: Gun-grade polyurethane foam · IQCON 14123 / 14122
One-component gun-grade PU foam for insulating, sealing and filling.
About
IQ PU Foam is a one-component, moisture-curing polyurethane foam for professional construction use — insulating, sealing, bonding and filling in a single step. Dispensed through a foam gun for precise control, it self-expands to roughly 78 times its volume to fill voids economically, then cures quickly to a resilient, flexible foam that insulates against both heat and sound. It is offered in two grades: a General multi-purpose foam and a High-Strength grade with more than double the tensile and shear strength for demanding fixing and installation work.
Key Features
- One-component, moisture-curing polyurethane — gun-grade for controlled dispensing
- High yield with roughly 78× self-expansion for economical void filling
- Effective thermal and acoustic insulation
- Strong adhesion to most building substrates (excluding PTFE, PE and PP)
- Rapid cure — tack-free in about 10 minutes, ready to trim or paint within 60 minutes
- Resilient and flexible after cure, absorbing vibration and movement
- Inert and safe once fully cured
- Two grades — General and High-Strength (over 2× the tensile and shear strength)
Typical Applications
- Installing door frames and window surrounds
- Acoustic infill for partition walls and sound-sensitive areas
- Sealing wall penetrations and pipe entries
- Void filling in walls, ceilings and roof structures
- Moisture-proof filling behind cabinets and joinery
- Insulating around refrigerators, sinks and bathtubs
