Insulating

Soudal provides reliable insulation solutions designed to improve energy efficiency, airtightness, and acoustic performance across residential and commercial projects. Whether you’re sealing gaps around windows and doors, insulating wall cavities, or improving thermal performance around service penetrations, Soudal products help create tighter, more efficient buildings.

Our insulation range includes high-performance expanding foams and sealants engineered for fast application, strong adhesion, and long-lasting results. These solutions reduce unwanted air leakage, minimise heat loss, and help protect against moisture ingress, making them ideal for use in walls, ceilings, floors, and roof spaces.

Trusted by tradespeople and DIYers across New Zealand, Soudal insulation products are easy to apply, quick curing, and available in multiple formats to suit different job sizes. From new builds to renovations, they deliver reliable insulation performance that saves time on site and supports better living and working environments.
