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 maximise the effects of our replacement windows, we created an A+ Plus window frame with five insulating chambers. We also incorporate a sash frame with six insulating chambers, as well as a bubble gasket which works in the same crucial way as a seal on a fridge freezer; it stops heat from escaping. The glazing itself is inventively comprised of carefully chosen materials which control the passing of heat between inside and outside. It allows the natural warmth of the sun to pass into the house, whilst internal heat is unable to escape.

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.

Most people only expect us to offer them one type of glass, the plain glass that you will usually find in most window designs. But Mitchell Glass likes to supply its customers with alternatives such as energy-saving glass which is specifically designed to drive down the cost of fuel bills and stop heat from leaking out of the windows. The energy efficiency of the glass you choose will be specifically labelled.

Privacy Glazing - When we retreat to our homes it is often about shutting ourselves off from the outside world but it isn’t always possible when you choose to have conventional plain glass inserted into your window design. We can provide you with what we call ‘privacy glazing’ which as the name suggests will give you an element of obscurity so that people passing cannot peer into your living space. Don’t fear that you will lose any natural light as you won’t.

It is only natural to be attracted to a certain type of window design because of the colour applied to it, particularly so when buying from Mitchell Glass as produce our full stock of windows in multiple colour variations. We always recommend that you try and select a finish that shares some resemblance to the original colour but on an even grander scale so that the window installation has a hugely positive aspect on the building.
