Our modern casement windows are designed to provide your home with a reliable, year round thermal performance. A multi chambered profile works to prevent the ingress of cold air, while double glazing keeps a vacuumed pocket between your home and the chilly winter weather.
With this, the energy efficiency of your home improves over time, with the casement windows allowing your home to sit at the optimal temperature. You could even see your monthly utility bills become cheaper thanks to the enhanced thermal retention.
We fit each of our casement windows with industry leading Q-Lon weatherseals are standard. Renowned for their unrivalled, consistent performance levels, they ensure that your home is fully protected against adverse weather.
With this, you’ll never have to worry about issues including mould, rotting or the forming of damp spots. What’s more, modern trickle vents ensure that all rainwater is filtered away from the profile, preventing misted glazing or any warping of the uPVC profile.
Our casement windows come with Espagnolette locking systems as standard. These metal locks are incredibly robust and durable, as well as multipoint in design. They’ll prove incredibly difficult to damage, allowing you to feel safe in your home.
These locking systems work in tandem with galvanised steel reinforcement, dog bolts and steel hinges to ensure that these windows offer the complete home security performance. They will protect your family now and for the years to come.
