Classic Style, Modern Performance

These heritage windows mimic the authentic look of steel windows with none of the performance drawbacks. One of the key benefits of our heritage windows is their market leading levels of thermal efficiency. These windows are double glazed as standard, helping you achieve a more comfortable Stevenage property without touching your thermostat. This could help your building better retain heat so you rely less on your central heating.

Heritage Windows Stevenage

Heritage windows are a long-lasting and affordable alternative to steek window systems. These doors feature slim sightlines associated with classic profiles but all the performance benefits of modern aluminium.

We work with Smart, a leader in the industry. Their aluminium windows can enhance the security, thermal efficiency and weatherproofing of a Stevenage home without compromising on performance.

Thanks to aluminium’s natural resistance to the effects of weathering and ageing, our heritage windows are a long-lasting installation. They will require minimal maintenance to keep them looking as good as new. Use our online quoting engine to generate a no-obligation price tailored to your specifications.

Thermally Efficient Heritage Windows

One of the key benefits of replacing steel windows with our heritage windows is their thermal efficiency. Our heritage windows are crafted with an innovative polyamide thermal break technology which creates a barrier between your Stevenage home and the outside world. A better insulated property will rely less on your central heating which could lead to minimise energy bills and a more cost efficient home.

Sustainable Steel Alternative Windows

We do not believe that updating your Stevenage property should have a negative impact on the planet. Crafted using aluminium, this material is one of the most sustainable available on the planet. Aluminium is the third most abundant material on the planet and can be recycled almost an infinite amount of times. When it gets recycled, it will not lose its structural integrity. The recycling process creates high quality aluminium which loses none of its properties and also uses just 5% of the energy it takes to create brand new aluminium profiles.

This is the second set of windows we’ve had fitted by Fenster. They are brilliant at every stage and I would highly recommend them. The staff are friendly and professional, they got the job done quickly and well, we’re very pleased with both sets of windows they fitted and would definitely use them again.

I contacted Fenster last week to see if they could help me. My French doors were failing to lock meaning we couldn’t leave the house. They sent Ben out the next morning who replaced the mechanism and also adjusted the door, closing up an annoying gap that’s been there for years. I wouldn’t hesitate to recommend Fenster to friends and family, a really helpful and efficient company.

We couldn't be more delighted with the professional service we received from Fenster Glazing. Nick turned up on time for the initial visit/quote which was fair and reasonable. After accepting the quote a survey was was carried out. The installers arrived on time and were polite and friendly. They covered everything up and left everything clean and tidy. After installation Perry called to check we were happy with the service. The quality of the french doors and windows installed were outstanding. We have no problem recommending this company. We would rate Service, installation and aftercare as 5 star.
I live in Milton Keynes, I contacted Fenster Glazing for an uPVC replacement door. From the beginning to the end, they conducted professional communication, from sales to the technicians coming to replace the door everything was perfect. I had a draught issue with my door and it is resolved now. I want to mention that I am also happy with the quality of the material of the door. I am hoping to have the same quality of service in the future if anything comes up—special thanks to Perry for dealing with everything. Ben

Highly recommended. I wanted a very specific style of doors to fit into our 1930s front porch. Fenster designed them, advised on colour & finish and they have produced exactly what I was looking for. The fitters were very polite and made sure everything was to my standards, and no mess left.
