Thermally Efficient House Extensions Chelmsford

Home Extension Features & Benefits

If you’re on the lookout for house extensions that can help you reduce your energy consumption, then you’re on the right track by coming here to Bluemanor. Our double glazing utilises the latest thermally efficient glazing for a naturally warm product. By trapping heat behind vacuum-sealed glass and anti-draught mechanics, you can reduce your reliance on central heating.

At the same time, this reinforced glass will also lend your double glazing a natural strength that easily outclasses competing products. This means that you can relax, safe in the knowledge that your windows are practically just as powerful as any solid wall. This is further bolstered with high-tech locking mechanisms and Yale security in the windows and doors of your home extension.

We also have a wide range of customisation options so that you can customise your product however you like. If you have a specific colour in mind, then we’ll have it. If you have a particular shape you’re after, perhaps our Victorian or Edwardian designs, then we’ll have that too. Simply get in contact with us today or head over to our quoting engine to find out more.
