Short Description:

Our PU foam is a high-quality polyurethane-based expanding foam sealant engineered for professional-grade gap filling, insulation, and sealing. The advanced formulation expands up to 60 times its liquid volume, penetrating deep into cavities to create a durable, airtight, and water-resistant seal. The fast-curing foam adheres to most building materials, including wood, metal, concrete, brick, and stone. It provides excellent thermal and acoustic insulation. Once cured, the foam is sandable, paintable, and trimmable. Suitable for construction, renovation, plumbing, and electrical installation. Available in fire-retardant grades for enhanced safety.

Product Description

Product Overview
Our PU foam is a premium polyurethane-based expanding foam sealant designed to deliver professional-grade gap filling, thermal insulation, and acoustic sealing across a wide range of construction and renovation applications. The scientifically formulated moisture-curing composition expands up to 60 times its liquid volume upon application, actively penetrating deep into cavities, voids, and irregular gaps to create a dense, homogenous cellular structure that effectively seals and insulates. This exceptional expansion capability ensures complete fill even in hard-to-reach spaces, eliminating drafts, moisture ingress, and thermal bridging that compromise building efficiency.
✔ Substrate Versatility: Strong bonding to timber, MDF, plasterboard, concrete, brick, stone, metal, and most plastics.
✔ Fast Curing: Hardens within 10 minutes and achieves full curing within 24 hours.
✔ Dimensional Stability: Will not shrink or sag after curing; remains flexible to accommodate building movement.
✔ Precision Application: Controlled flow rates minimize waste even in tight spaces.
Available in both standard and fire-retardant formulations (classified as class B1/B2), our PU foam meets the highest safety standards. Trusted by builders, contractors, and DIY enthusiasts worldwide, it provides an efficient, durable, and reliable solution.
