Timber and Aluminium Frames
uPVC may be the most popular and widely recognized material for double glazing units, but it is by far not the only option available to you. uPVC frames are hard-wearing and strong, being able to be left with very minimal additional upkeep and immensely affordable; however, they aren’t very environmentally friendly when it comes to their manufacturing process, and the thick white frames can often clash with a properties appearance.
Timber frames are the more traditional option, with ornate detailing resulting from its professional carpentry, and is suited to any type of property. However, it is the more expensive option and requires more upkeep such as varnishing, repainting and sanding as over the years it can begin to suffer from natural wear-and-tear.
Aluminium frames are, on the other hand, very hardy and, like uPVC, can be left for a long time with very little additional upkeep needed. Perfectly suited to both traditional and modern properties, aluminium frames are made from sustainably sourced metal and is environmentally friendly in its manufacturing and can be easily recycled.

After much deliberation we decided to replace our old 1960s front door with a picture window. The door was never used as we have other doors which are used and it was just an unsightly and dated part of the house. After consulting with a very helpful and knowledgeable member of the team we planned the look and eagerly awaited the installation. The installation was done extremely professionally, you hardly knew he was there, he removed the old door and frame and took that for disposal. The cleanup afterwards was impeccable. The window with its beautiful patterned glass has totally transformed my hallway and brought my home into the 21st Century. Thank you Starglaze!
When Starglaze turned up yesterday to do our patio doors, back windows and back door, there was only one fitter to do the job. We really thought he was going to struggle to get the job done and thought he would have to return the next day but he did a fantastic job and after getting everything done, he went the extra mile and put our blinds back up for us. Nothing was too much trouble for him. We are very happy with the work and would recommend Starglaze to anyone. Thank you.
