What is Internal Wall Insulation?
Internal wall insulation (IWI) involves adding an insulating layer to the inside face of your exterior walls. It is also known as internal insulation.
Best suited for properties with solid walls, listed buildings, or homes in conservation areas where external changes are restricted or not possible.

- Mineral Wool - Non-combustible, excellent for soundproofing and insulation.
- PIR (Polyisocyanurate) Boards - Slim profile with high thermal efficiency.
- SWIP Internal Wall Insulation (IWI) - A certified system-based insulation solution for solid or cavity walls.
Why We Use SWIP Material
SWIP Internal Wall Insulation (IWI) provides a system-based approach to internal wall insulation. The system has been tested and certified to demonstrate that all components work together as designed to deliver the required performance.
The SWIP IWI System is designed for upgrading existing solid or cavity walls. It consists of thermally engineered composite studs and insulation slabs, which can be combined to provide greater thicknesses of high-performance thermal insulation than achievable by using a single thickness.
