Security for your Bexleyheath home

Purpose-designed reinforcement chambers within the uPVC structure ensure the flush casement window will be able to keep you and your home safe no matter the location. We create our doors with the absolute highest standards of materials to attain our promise of security for your home.

Impermeable Structure

To make sure that your home stays as clean and as possible, our casement windows are designed to resist the strongest of weather. Drainage channels built into the uPVC creates quick drain flow and avoids water build up. Five enclosed chambers within the casement window frame also add strength and thermal efficiency to your new uPVC flush casement window.

Greener Environment for Bexleyheath

We want to create a more sustainable environment for the future. We have incorporated this desire into our flush casement windows. The total design is 100% bio-degradable, which means less material is wasted and more can be recycled.

Historic Appeal

Our casement windows are designed to resemble the windows of the 19th century. With a modernised structure for a notable design, our uPVC flush casement windows are timeless copies of classic timber window frames at a lesser price.

Gorgeous Form

Our uPVC casement windows come in a wide variety of colours and styles, meaning that you will have multiple options to compare so you can the right one for your property. A wide range of woodgrain finishes and textures ensures you will find a suitable and long-lasting replacement for timber wood frames, at a competitive price.

High Thermal Efficiency

Our uPVC flush casement windows are designed to keep you wam even in the worst of weather conditions. Our windows are designed to incorporate either double or triple glazing, depending on our preference. So that you can turn your home into an energy-saving household. Five enclosed pockets embedded into the structure of the uPVC frame further allow for improved weather performance.

Our casement windows also come standard with an extra seal flipper and a 3mm glazing pad. This is to be 100% certain warm air isn’t escaping through your new casement window frame. All of these excellent heat-saving features don’t compromise on the chosen style or outline of your new window. They are fully enclosed into the material which allows more glass and more personalized woodgrain foil textures to resemble the beauty of 19th century timber frames.
