Reduce your reliance on expensive heating systems…

Owing to the continued development and improvement of the products and methods that we use, our windows will make your home more energy efficient than ever before. They will reduce your reliance on artificial heating systems which are nearly always expensive to run and harmful to the environment. Our windows achieve this by preventing internal heat from escaping, but also by allowing external warmth from the sun to pass into your home to create a naturally warmer room temperature.

Once you have settled on the kind of window you want, you can then tailor the design to your liking, including selecting the colour, glazing and hardware.

There is sure to be a combination which will effortlessly achieve the desired effect…

If you wish to turn your UPVC windows into a statement feature of your home, our colour finishes are perfect for you. Cream, Grey, Chartwell Green and Black-Brown are among the most popular and boast the same low-maintenance qualities as our most popular gloss white option. On top of this we also offer dark Red, Blue and Green colour options. All of the colours above showcase a woodgrain texture which mimics the appearance of painted wood to excellent effect.

Glass doesn’t have to be plain…

Whether you choose clear or textured glass, it’s important to put some thought into the glazing. Privacy glazing, often used for bathrooms, is a great investment for your home. The combination of both privacy and energy efficiency delivered simultaneously is offered through a range of glass designs which each create a different visual effect with textured patterns. Please ask your design consultant about the full range of textured glass and the levels of privacy that each pattern provides.

A variety of designs and styles…

Our handles are beautifully created by our experienced craftspeople who have perfected their design and functionality. You can see the numerous designs when you visit us at our York showroom.

With an ultra-secure locking system built in each handle, you can be sure your home is well protected.
