ArboSeal Pro B3 Gap Filling Foam Hand Held 750ml (Box of 12)

ARBOSEAL Pro B3 Gap Filling Foam Hand Held

ARBOSEAL Pro B3 Gap Filling Foam Hand Held is a one-component, ready-to-use polyurethane straw foam for general filling, sealing and insulating applications in construction. It is designed to fill holes, seal joints and penetrations, support window and door frame installation, and improve thermal and acoustic insulation performance.

Product Overview

This hand held PU foam offers good volume expansion for effective filling while maintaining low curing pressure to help reduce the risk of deformation in surrounding building elements. Once cured, the foam does not shrink, helping maintain a durable seal and minimising the risk of joint separation from the substrate.

Key Features

• One-component, ready-to-use polyurethane straw foam
• Suitable for general filling and sealing applications
• Good volume expansion for effective gap filling
• Low curing pressure to help avoid deformation of building elements
• No shrinkage after curing
• High thermal and acoustic insulation value
• Adheres well to wood, concrete, stone, plaster, metal, PVC and polystyrene

Performance Benefits

ARBOSEAL Pro B3 Gap Filling Foam Hand Held is designed to provide reliable sealing and insulation across a wide range of site applications. Its combination of volume expansion, low curing pressure and stable cured performance makes it suitable for projects where effective filling, reduced thermal bridging and dependable acoustic and thermal insulation are important.
