Our Internal Wall Insulation range is designed to improve thermal performance and comfort from inside the property, making it ideal for renovation, retrofit and projects where external insulation isn’t suitable.

The range includes internal insulation solutions that help reduce heat loss, manage moisture and create a stable base for internal finishes. Suitable for solid walls, problem properties and room-by-room upgrades, internal wall insulation can significantly enhance energy efficiency while maintaining control over internal build-ups and finishes.

Whether used as part of a full refurbishment or a targeted thermal upgrade, these systems are selected to work reliably with compatible plasters, fixings and accessories, supporting long-lasting performance and a high-quality internal finish.
