Features & Benefits

Precise Fit Profile

Precise Fit Profile

Your windows are securely fastened to the frame. This prevents draughts and condensation throughout the manufacturing process. As a result, your Letchworth home will be more insulated. The profiles come in a variety of sizes, including 70mm sculptured or chamfered profiles. You can also choose between 28mm and 36mm triple glazing.


Weatherproof Design

Weatherproof Design

Our double and triple glazed windows and doors are impervious to water and will withstand even the most severe weather. Windows made of uPVC are very low-maintenance because they won’t rot, warp, or fade. The thermal efficiency of the windows guarantees cost savings on heating and cooling and adequate insulation for the building.





Family Friendly

Family Friendly

When it comes to family homes, our casement windows are the perfect option. These windows are carefully designed to minimise finger trapping risks and they also have child friendly restrictors. As a result, you can rest assured that the windows will be much less of a hassle to operate with curious little ones or pets around.

A+ Energy Rating

A+ Energy Rating

Liniar, the provider of our uPVC windows, guarantees that they will meet or exceed the requirements for an A+ energy rating. When you couple cutting-edge double glazing with this profile, you have a weatherproof structure that keeps warm air inside and cold air out.
Due to the multi-chambered profile of the windows, your home will be kept at a more comfortable temperature year round. When you opt for triple glazing, you’ll get both low U Values (as low as 0.8 W/m2K).

Ultra Slim Sightlines

Ultra Slim Sightlines

uPVC casement windows offer a wide field of vision while maintaining a minimal frame profile, making for a truly breath taking vista. This way, your indoor and outdoor spaces may flow together without any interruptions. Your Letchworth home will look more big and open as a result of this. In addition, the minimal sightlines will let the most light into the home, reducing the need for artificial lighting.

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.
