Choice of finishes

As well as fresh white, the time style beauty of FS70 can be complemented by our woodgrain finishes in either Rosewood or Antique Oak.

And you can even choose an exterior woodgrain finish combined with fresh white on the inside, so matching your decor is made easy.

Why choose us

  • Best weatherseal

    Old PVCU windows used to have a thick black or grey gasket line around the glass area. No more. FS70 has a unique discreet gasket that lets in more daylight - yet provides a full seal around the glass designed to prevent leaks and draughts permanently.

  • Any window or door you want

    Every home is unique, which is why we make every FS70 frame to order. We can use FS70 to create virtually every window configuration you want - to match your existing frames (whatever they're made of) or to update the style and appearance of your home.

    FS70 is also suitable for entrance doors, so you can give your home a complete external makeover with one, matching frame style.

  • Thermal efficiency

    FS70 is a new breed of PVC-U windows designed to exceed the government's stringent energy efficiency regulations which most old style PVC-U windows do not meet. FS70 windows and doors are manufactured with an extra thermal break chamber in the frames which significantly improves it's thermal energy rating.

  • Should you update your old PVC-U windows to FS70?

    FS70 meets the Government's energy efficiency targets - it is at least 20% more energy efficient than your old frames

    FS70 is more secure - it holds security Kitemarks from the BSI and the Police-approved Secured by Design scheme

    FS70 looks better - the slimline style of timber

    FS70 costs less - thanks to technical advances, pound for pound you'll pay 45% less for new windows today compared to 10 years ago

Energy Windows

Forget winter's chill. When it comes to keeping you warmer, new double glazing can more than halve the heat loss from your home. The bigger the air space between the two planes of glass, the less heat is lost, up to an optimum of 20mm, and the cost of replacing single or older double glazing with new regulations compliant double glazing is recoverable in future energy savings.

A Warmer and Quieter Home

PVCu has excellent insulation qualities and, together with the double glazing, it acts as an effective barrier that helps reduce heat loss and outside noise levels.

An Energy Efficient Solution
Advantages of PVCu
  • Reduces heat loss
  • Reduces outside noise levels
  • Reduces heating bills
  • Complies with new regulations
  • Emissions can be reduced by up to 70%
New Levels To Reduce Heat Loss

Thermal performance is measured in U-valves and all new PVCu framed windows and doors must now have a maximum U-valve or 2.0 W/m2K

Document L is the section of the latest government building regulations that stipulates that all new windows (and doors with 50% glazing or more) must comply to certain energy conversion levels to help reduce harmful greenhouse gas emissions.
