Double Glazed Windows

Four Point Installations | Double Glazed Windows

Enjoy absolute comfort with lower energy bills

If you find that in your home you’re consistently losing a great deal of heat through your property’s various window apertures, getting your windows double glazed is a near-essential that will see you suffer no longer. Double glazed windows utilise two layers of glass as opposed to the traditional one, providing twice the amount of insulation and heat retention to make for a warmer, more energy efficient home.

Whether for use in your home’s existing set of windows or as part of replacement units entirely, double glazing makes for a warmer home because heat is better retained. This means you’ll be less inclined to switch on your home’s central heating and therefore will soon discover that you’ll start saving on energy bills. Creating funds which can be better implemented elsewhere.

Double Glazing Installation in the South East
"We needed a new 5 meter sliding door for our kitchen extension and a new front door. I had heard good things about 'Four point installations' and so we decided to go with them. They were competitively priced and the service was excellent throughout the process. I would definitely recommend them."

An extra layer of protection against intruders and the cold

All of the various window styles featured in our range can readily accommodate additional double glazing, meaning that practicality never needs to take priority over the style you wish to achieve with your home’s overall visual aesthetic. If you’re tired of suffering from frequent cold spots or pesky draughts, double glazing raises your home’s U-value meaning heat is successfully retained.

For those concerned with home security, the simple act of inserting another glass pane within the frame of your home’s windows can provide a much tougher time for potential intruders who attempt to break in. Keep out any unwanted guests as well as unwanted temperatures with double glazing services provided by our team.

Double glazing benefits:

  • Suitable for use in both aluminium and uPVC frames
  • Reduces your home’s energy bills (potential savings of up to £170)
  • Resistant against condensation
  • More layers of defence against intrusion
  • 10 year insurance-backed guarantee
