Sovereign’s Double Glazed Window Range

Window Styles To Choose From

Sash Windows – Very popular for traditional style homes, we can install a range of Sash windows that will fit the style of your property. These include Georgian, Edwardian and Victorian. All of which achieve highly aesthetic results. 

Tilt & Turn Windows – A versatile and practical style of window, a tilt and turn window is designed with two hinges so you can vertically tilt the window to allow air to circulate, or inwards like a traditional window to allow for ventilation. 

Bay Windows – These types of window styles allow for a great panoramic view due to the use of usually three or more window units, which is perfect for those looking to achieve plenty of natural light into their living spaces. 

Secondary Glazing – These types of windows are suited where a complete renovation of the windows are not needed, instead, secondary glazing adds a second internal window to add an extra layer of insulation and security. 


Window Materials We Offer

uPVC – Offering low maintenance with high insulation and security, uPVC windows are among the most common materials we use in our everyday installations, simply because so many modern homes use the material because of its durability, energy efficiency and effective insulation, to name a few benefits.

Timber – The ideal choice for most period properties. Effortlessly preserving your home’s aesthetic, our timber frame windows’ toughness allows for double or even triple glazing to be installed. 

Aluminium – Lasting longer than a uPVC window, aluminium frames are a good way to get extra durability without a significant extra cost. Our modern aluminium windows offer added thermal breaks to match the efficiency found in most other materials.

Composite – Using both aluminium and timber, a composite frame offers a longer lifespan than uPVC, along with simple maintenance and high security. Composite framed windows are one of the most complete windows you can get, although the cost to replace them can be a little higher.

Don’t take our word for it, see what our clients say

I recently had porch doors fitted by Sovereign Glass. The Price was very competitive. They arrived when they said they would and installed the doors without a hitch. The fitters were very considerate and polite. The doors look very good and have been much admired, the house is certainly warmer. When I Phoned to make the initial appointment I was very satisfied and we created a contract. I had patio and windows fitted the year before . When I hit a hitch with locking the door I phoned and they came within as hour corrected the hinge and explained how to avoid the problem in the future.
