Entrance doors for modern and traditional properties

At Techniglaze, our doors can be specified in a wide selection of styles and designs. For modern properties, both uPVC doors and aluminium entrance doors are excellent options. Our uPVC doors are perfect for busy homeowners. Their low maintenance finish will never need painting and with only the occasional wipe down with warm soapy water, will stay looking like new for many years. Aluminium doors are also extremely low maintenance. Available in any RAL colour, they can be personalised to your taste.

Patio doors for property enhancement projects

When you want to upgrade your home’s patio entrance, we have several options to choose from. If floor space is limited, our sliding patio doors are the perfect choice. Operating on a durable smooth sliding track system, they’ll provide years of pleasure with zero impact on the surrounding area. When you want to open up your home to the great outdoors, bifold doors are the best choice. They can be fully opened to create a seamless link between interior and exterior space or used as a normal traffic door when required.

Can you buy a uPVC door without replacing the frame?

Both uPVC and composite doors are designed as a complete unit, including the door slab, frame, and specific hinges, which means that the door cannot be installed without its corresponding frame.

What is the lifespan of a uPVC front door?

While uPVC doors are expected to last for about 20-25 years, composite and timber doors have a longer lifespan of at least 30 years. However, it can be difficult to determine when it’s time to replace your door.

Our latest reviews

Ali & Fi

We are delighted with the windows, and have already been complimented by our neighbours on the upgrade.

Tyler and Paul were very professional and showed good initiative for the inevitable adjustments that needed to be made. They were particularly considerate of our house, it’s character and our pets! Please pass on our thanks and comments as appropriate.


We are delighted with the windows. As you know we were concerned that they would look different and more “clunky” but really you can’t tell the difference except that the new ones are not falling apart!!! The guys who did the fitting were also good. They were working in freezing fog, really cold but they carried on regardless, they were extremely tidy and cleared up after themselves.

Roy Robinson

I am delighted with the recent installation, it’s good to look out of clear windows. The work was carried out professionally by two excellent gentleman.
I will not hesitate to contact you when I am ready to replace others, also would certainly recommend you to others.

Excellent customer service, range of products and attention to detail. I honestly can’t rate them highly enough. They stepped in and came to the rescue after Salisbury glass cost us 8 months of time and 100k in increased material costs.

These guys have been great to us. Helped us out at short notice after we were badly let down by another supplier. We asked for several minor details that were not standard (e.g. different locking mechanisms), and they were flexible and open to ideas. We ended up also commissioning our front door from them; it is super sturdy and beautiful. Always courteous, professional, and good payment terms.

First class service for my window repair, with tricky access issues and a large, heavy glazed unit to install. Really glad I chose this company.

I was looking for a company that could deliver a bespoke pair of roof lights in the Alitherm system. Techniglaze offered the best price and worked with us to ensure the sizes were exactly right and conducted the sales process very professionally. The product is first class and we are exceptionally pleased with the service and product. I can highly recommend Techniglaze.
