Manufacturing – Rely on us for all the technical stuff

Our factory is one of the most advanced manufacturing facilities in the UK. Our state of the art machinery and our production team are highly experienced, always looking to advance the way we work. All of our products are lovingly crafted by our dedicated staff in order for them to perform brilliantly for decades to come. They also go through multiple tests against the weather, overall performance and security.

Our windows are independently tested by the British Standards Institute, we have quality certifications for all materials, construction, security, weather tightness, operation and strength performance. Also, all our windows are tested to destruction, to ensure they meet the requirements of enhanced security.

We understand that you want your family to be safe. We were the first UK window company to achieve coveted BSI certification status and we will be the first in line for any new legislative controls or testing because, like you, we want our products to be the best they can be.
