We offer a wide range of insulation materials, fixings and finish choices to make sure that the performance and the aesthetic of our systems are perfectly aligned to your needs.

Why use External wall insulation?

Our External Wall Insulation is one of the best ways to protect a building and its residents from the elements. Our systems insulate properties, reduce energy costs and keep inhabitants warmer.

In addition to retaining heat and providing buildings with a highly durable finish, our External Wall Insulation also offers the following benefits:

✓ It eliminates cold bridges in property walls
✓ It provides a new, improved look to properties in need of refurbishment
✓ It pushes the dew point out to help prevent condensation and damp
✓ It protects the structural fabric of buildings from the elements.


A wide range of our products and systems have been stringently tested and are independently certified by the BBA, providing you with the reassurance of our construction products and systems.

30 Year Expected Life

Correctly applied, our Stormshield External Wall Insulation systems have a very long lifespan, particularly if they are properly maintained, easily exceeding 30 years of constant exposure in the UK climate.
