Next 45+ Low Expansion Gun Foam 750ml Professional Single-Component Polyurethane

Product Overview

NEXT 45+ Low Expansion Gun Foam is a single-component polyurethane sealant used by professionals and contractors for thermal and acoustic insulation. Packed in a 750 ml canister with a pistol applicator, it is intended for applications such as windows, doors, parapet sealing, and cable duct insulation in residential and commercial construction. The foam cures upon contact with air moisture and delivers a consistent cell structure for stable performance.

The product distinguishes itself with its low expansion characteristic, which minimizes material waste and eliminates risk of structural deformation around sensitive joints. This property is particularly valuable for procurement in projects requiring precise gap filling, such as window installation, HVAC, and cable passthroughs. Ideal for bulk supply to installers, building maintenance teams, or contractors who need high-yield and fast-curing sealant for frequent use.
