Cost Effective.

Internal wall insulation provides a cost-effective alternative to external wall insulation.

Approved Materials.

Westville utilise the brand new ThermoShell IWI system, providing greater results than standard insulation.

Internal Insulation

Westville utilise the ThermoShell IWI system which is a brand-new internal wall insulation system designed for upgrading existing solid external walls. It consists of thermally engineered insulated studs and water repellent glass mineral wool insulation slabs, which can be combined to provide greater thicknesses of thermal insulation than would be achievable by using a single thickness.

What is Internal Insulation?

Internal wall insulation is the insulation of the internal surface of external (heat losing) walls. This process can provide a cost-effective alternative to external wall insulation but should only be considered following a survey of your property by fully trained insulation engineers. If you are considering a major refurbishment like a new kitchen or bathroom this can be an unmissable opportunity to insulate the walls before installing the new fitments. Likewise, if you're planning to redecorate this is also a good time to look at internal wall insulation.

Westville use EcoStuds in the IWI process, which are a composite of high-performance extruded polystyrene (XPS) insulation and Oriented Strand Board (OSB). The OSB is manufactured from timber supplied from Forest Stewardship Council (FSC) certified forests. The IWI System has been designed to simplify the process of upgrading solid masonry walls while delivering high levels of thermal performance.

Westville have a vast amount of experience installing Internal Insulation on a wide range of homes throughout the UK, helping homeowners make their property more energy efficient, protected and beautiful.
