Expert Installation With Great Value
Double Glazing Stevenage
At Fenster, we install high-quality double glazing in your home in Stevenage. When you choose double glazing, it comes with lots of advantages for you to consider. You will get lots of security and thermal efficiency, which saves you money on your energy bills because you don’t need to use the central heating or turn on the thermostat. It will increase your comfort and safety too. You have a choice of uPVC and aluminium windows and doors.
When you choose Fenster for double glazing, you can benefit from many different customisation options including a range of colours and finishes that can help you personalise your Stevenage home easier. Go for a vibrant colour that will help your home stand out, or you can even go for something more muted to blend in with your property. The choice is entirely yours. We install products including uPVC casement windows, flush casement windows, sliding sash windows, aluminium windows, aluminium doors, uPVC doors, composite doors, bifold doors, French doors and patio doors.
Double glazed windows can also ensure your home has less condensation because they will reduce the amount of moisture on your window or door. This is because the frames are airtight and watertight, so you will not have to worry about water or cold air seeping in. As a result, your home will be much warmer in the long run.
The double glazing that we install is very high quality and lets in floods of natural light into your home. This will save you money on your electricity bills because you won’t have to turn on the lights. Furthermore, the thick panes create a robust thermal barrier which will keep natural heat in your home in the winter, reducing rising energy costs. It also works well in the summer because it can help reduce the glare of the sun while letting in more fresh air. This will save you money on your air conditioning.
With more units being used in double glazing, it can help you feel safer from burglars because the windows have multi point locking systems and robust hinges included. This will keep you and your loved ones safer for longer. The units will also help increase your privacy levels as well, which is ideal if you live in a noisy area such as an airport or a busy road. These sounds will be reduced to a hush.
It is very low maintenance as well, so you can enjoy it for longer. All it requires is a damp cloth and soapy water, and the windows will be in pristine condition. What’s more, if you clean the windows once a month, this will make them more durable.

Thermally Efficient uPVC Windows and Doors
At Fenster, we offer double glazing for both your windows and doors. One of the main benefits is that they are thermally efficient, while you can feel very confident that they will be secure in the long run. Less energy will be used to heat or cool a room, which means you don’t have to use your central heating or the thermostat.
When you add more layers of glazing, you will save money on rising energy costs, and you can spend money on the things that matter. This way, you will have more control over your temperature, saving you money all year round. The doors contain aluminium extrusions that are separated by polyamide thermal breaks.
They are reinforced with glass fibre and a PU insulated chamber, which help you stay warmer for longer periods.
Additionally, lowering your energy usage will reduce your carbon footprint. You will save the environment and contribute to a greener planet in the process. There is something out there for everyone, so we are confident we will find something for you.
