Casement Windows Stevenage

Casement windows are a very popular design for your Stevenage home because they have a simple and elegant design. They will help you save money on your energy bills because they help retain natural heat in your home, reducing the need to turn on the central heating and your thermostat.

The casement windows are crafted from modern uPVC, which is a very robust material and is very easy to maintain. Their durable strength means they won’t rust, warp, or fade in tough conditions and will stand firm against the worst of the Stevenage weather.

Features & Benefits

Precise Fit Profile

Precise Fit Profile


Your windows are fitted tightly to the frame. This is part of the manufacturing process, ensuring that draughts and condensation are eliminated. Your Stevenage home will be better insulated as a result. You can even get the profiles in different sizes, such as sculptured or chamfered profiles at 70mm. These are available with either 28mm or 36mm triple glazing as well.

Weatherproof Design

Weatherproof Design

Your windows are also entirely weatherproof too because you can benefit from double or triple glazing, which will stand firm against tough conditions. uPVC windows are very easy to maintain as well because they don’t rust, warp, or fade. The windows are also thermally efficient because they trap warm air inside your home, making sure that you will save money on energy bills and that your home is insulated.





Family Friendly

Our uPVC windows are family friendly. This is because they come with secure child friendly restrictors that will stop fingers from being trapped. You will feel confident that the windows can open and close easier.

A+ Energy Rating

A+ Energy Rating

Our uPVC windows are supplied by Liniar, which are capable of giving you an A+ energy rating. This is thanks to their cost effective double glazing that will let plenty of natural light into your home. In addition to this, you will get U Values as low as 0.8 W/M2k, which will reduce your energy consumption and your carbon footprint too. The windows can trap pockets of warm air inside, and leave cold air outside, so you and your family can feel warm and comfortable in the process. They are also capable of achieving WER energy ratings.

Ultra Slim Sightlines

Low Maintenance Casement Windows

One of the most important benefits about your windows is that they are very low maintenance. This means they are easy to clean, and you can enjoy them for much longer. The only thing you need to do is wipe them with a damp cloth, and they will look as good as new. If you clean the windows once a month, then they will last for many years to come.

When you choose uPVC windows from Liniar, they can stay draught free because they include a double action bubble gasket which delivers a continuous seal in the corners, leaving the windows leak free for a long time. That way, your windows will be better equipped to handle tough weather conditions.

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.
