Designed with your project in mind

We are experienced in designing products to exactly match your requirements. Whether it’s particular load weights or opening configurations, our designers will work with you to create glazing solutions perfect for your project. Depending on your specifications, we will design products that meet the necessary parameters to ensure your project is successful.

Due diligence is given with all our products; whether this is for the acoustic insulation or snow and wind loads that our products have. We use a quality and high performing supply of Deceuninck’s profiles suitable for most applications. However, if you require a bespoke design we can easily meet whatever specifications necessary.

Ticking every box

Accreditations are extremely important to us and we are proud to offer all of our products with Secured by Design status. This highly sought after status can be used by you to impress your customers and will give them the peace of mind that their home or business is protected.

Our products all meet the Lifetime Homes standard. This is a concept which was developed to ensure that homes are accessible and inclusive for everyone. There are a range of different requirements these homes must pass including having window and door handles at a height that those with restricted movement can access. We are committed to maintaining these standards and working with housing developers to create homes suitable for all.
