Our casement windows are double glazed and fully sealed, using the very latest glass technology to provide superior insulation giving you great energy efficiency in your home. Our A+ plus casement windows bring together a window frame with 5 insulating chambers, making them extremely tough and thermally efficient.
The outermost frame of a window is the part which is mounted to the walls of your house and provides a fixing for the opening sashes to be fitted into. A window’s outer frames and sashes – often rectangular or square, but in some cases other shapes – are created from lengths of ‘profile’ which are designed to look good, perform excellently, and be easily installed into domestic properties.

For many households, the amount spent on heating costs is one of the biggest expenditures they face. However, you can reduce your reliance on expensive heating systems by replacing your outdated windows with our thermally efficient alternatives.
Once installed, heat will no longer be able to easily escape through the glass and frames of your windows and you will be able to enjoy a warmer and more comfortable home that’s cheaper to heat.
PERSONALISE THE DESIGN
Once you’ve chosen your preferred window style, we can take you through the steps to customise the design. We’ll start with coloured finishes, then move on to glazing and hardware.
An outstanding range of colour finishes…
Find a classic or on-trend colour that works for you and your home. White windows always look timeless, but our UPVC can be finished in a variety of unique shades that will inject character into your home. Some of our up and coming colours and woodgrain finishes are proving to be popular with modern homeowners, including Chartwell green and Irish Oak. The opportunities to style your windows are endless!
Create the perfect balance of privacy and style…
The glass is such an integral part of your window to get right. Depending on your preferred visibility, the glazing on your Extreme windows can be chosen in privacy or clear. For certain rooms like bathrooms, many Permaframe customers opt for our privacy glazing which still invites maximum natural light inside.
Handles that perform as well as they look…
As a Permaframe customer, you have access to several traditional and contemporary handles for your Extreme UPVC windows.
In addition to their carefully crafted designs, our handles have a secure locking system built in, providing you with the ultimate defence in terms of security.
