Energy Efficient Windows | Energy Efficient Doors | Northern Ireland | Senator Windows Northern Ireland


Having led the way in energy-efficient windows and doors for over 30 years, Senator Windows is proud to manufacture the new Senergy Plus range. These energy efficient windows, made from lead-free PVC material, in fact exceed the energy standards set down by government. As a result, the innovative Senergy Plus window range will not only cut your heating bills but will also be your contribution to a healthier environment. With today’s global awareness of climate change, many people are looking for new ways to reduce energy and carbon emissions and the Senergy Plus range allows for you to do that.

Installing energy efficient windows and doors will work to save you money in the long run as well as being a responsible undertaking for the environment. They help to conserve heat within the home by creating a barrier from wind and rain and resisting condensation, while simultaneously allowing ‘free’ energy – in the form of heat from the sun – to warm up the home.

What is a Window Energy Rating?

Window Energy Ratings use an A-E ratings guide, similar to that used on electronic goods such as fridge-freezers and dishwashers. The existence of the ratings label allows you to make an informed decision on the window you are buying in order to know how energy efficient it is. Any further information can be attained from your helpful Senator representative.

Energy Efficient Window – How Will I Know?
All you need to do is to look for the labels! The window should have a BFRC (British Fenestration Rating Council) certificate and if it does not, then it’s not a registered Energy Efficient Window.

Had my windows and doors supplied and fitted by Senator Windows very happy with the advice I was given regarding security of windows and doors and different designs of windows I could choose from. Good Experience.

Senator Windows replaced windows at my house and I am very happy with everything. The fitter was very neat and tidy and Senator Windows provided a fantastic service to me. Would recommend Senator Windows.
We are very pleased with the complete end to end job. The quality of your sales service, product and installation was excellent. The installation crew cleaned up each day, and taking into consideration the size of the job, my wife and I were very satisfied with the end result.
