1. Heavy duty frame with high gloss finish - low maintenance and extremely durable.
2. 4mm clear low ion outer pane - allows more natural heat and energy into your home.
3. 4mm softcoat inner pane - for maximum heat retention in a home.
4. 20mm cavity filled with 90% argon gas - inert argon gas reduces cold radiation.
5. Warm edge spacer bar - far less conductive than aluminium spacer bars.
6. 6 chambered 70mm sash - for ultimate thermal efficiency.
7. Concealed bubble gasket - 0% leakage, as important as the seal on a freezer.
8. 5 chambered 70mm outerframe - for maximum strength and performance.

To help you maximise energy savings and get the very best thermal efficiency indoors, we have created an A+ Plus window frame with five insulating chambers. You also have access to a sash frame with six insulating chambers and a bubble gasket that works very similarly to the seal on a fridge freezer by stopping heat from escaping. So far as the glazing is concerned, we use various selected materials to ensure that any glass provides sufficient temperature control. This stops heat from escaping and allows the warmth of the sun to get indoors.

Once UPVC started being utilised as a window material it fast became a popular choice for those on the lookout for a brand new set of replacement windows. What UPVC is so good at is eliminating heat loss and effectively utilising any heat generated in the home, plus it doesn’t need any care or attention as it is totally maintenance-free. All you literally have to do to restore its finish back to its best is give it a good wipe with a wet cloth now and again. UPVC windows really do look after themselves as well as your home.

Privacy Glazing – Your home may be located in an area where your privacy is somewhat compromised. If this is the case and you find it off-putting having people easily being able to look into your house, check out our privacy glazing. A window equipped with privacy glazing will obscure the view passers-by have when they set their eyes on your interior, without you losing any natural light of the sun.

The most fun part of buying replacement windows is selecting a coloured finish for the design. We suggest that you take your time deciding on a favourite as we have a multitude of colours available. You may want to play it safe and opt for a colour that’s reminiscent of the colour you had applied to your old windows or go wild and pick something that completely contrasts with it. Either way, our colour palette will accommodate your taste.
