Are you wasting money every year on your energy bills? As the price of gas and electricity continues to rise, it’s important for many people to limit the amount of energy that they use and reduce their carbon footprint.

To improve the process of buying windows, they are all given Thermal Rating Register Window Energy Ratings which are thoroughly tested before they are rated.

Polar Windows has a wide range of solutions including uPVC double glazed windows that will help to make your home more energy efficient, saving you money and reducing your Co2 output; we offer a choice of windows with Thermal Rating Register Window Energy Ratings from A-C.

Just by making the change from single to double-glazed windows you could reduce your carbon emissions by as much as 720kg in a year. The average house will lose 20% of its heat through it’s windows; our uPVC casement windows are ‘C’ rated under the Windows Energy Rating scheme, which could mean an annual saving of £233.55 (this is based on the average family home with 3 bedrooms and gas central heating). Our uPVC windows are one of the most eco-friendly on the market, reducing Co2 emissions; keeping heat in and icy winds out, they can save you money, keep your house warm and reduce your carbon footprint.

In addition to installing double glazed windows, the type of glass that you use in your windows can also help your home be more energy efficient. By using glass produced by Saint-Goban Planitherm (SGP) in your windows you will improve the energy efficiency of your home. The new energy efficient double-glazing from SGP, when installed in good quality window frames, will help meet the guidelines provided by the Energy Saving Trust.

Our uPVC Windows are recognised as energy efficient and include the following benefits:

  • Save money on fuel bills
  • Advanced Performance energy efficient windows achieving window energy ratings A to C
  • High performance windows reduce heat loss by 30%
  • All Polar Windows products are free from hexavalent chromium (Cr VI), years in advance of international targets
  • PVC -U profiles manufactured in accordance with BS EN 12608 are expected to last in excess of 40 years according to the British Standards Institute
  • PVC-U can be recycled over 10 times without deterioration in molecular quality and has a total life span of 400 years
  • PVC-U is a multi purpose material and glass and steel in the window unit can also be recovered
  • The PVC-U industry is committed to recycle 100% of collectable waste by 2010 as part of the Vinyl 2010 charter.

In addition, Polar Windows also includes Recycled Composite Material (RCM) reinforcements for its PVC-U window and door profiles, and we are committed to ensuring we offer sustainable solutions for future generations, by recycling and re-processing post industrial and post consumer waste. The introduction of RCM across our portfolio of window and door profiles is essential to our continued commitment to the environment.

RCM has been approved by the Waste & Resources Action Programme (WRAP) and has been added to their guide to construction products:

  • Manufactured from reclaimed composite material is fully and easily 100% recyclable
  • RCM is less conductive than steel increasing thermal efficiency making it easier to achieve a higher energy rating
  • More than 35 years life expectancy
  • Does not corrode or rust
  • User friendly, easier to install, lighter and easier to transport

At Polar Windows we operate a comprehensive environmental policy, which includes recycling a variety of materials as well as post consumer waste. Polar Windows continues to implement new procedures in order to minimise its impact on the environment. We work closely with our suppliers in order to ensure we use components and products that have minimal environmental impact and offer excellent whole life costings throughout their lifetime with minimal maintenance required.

With a wide range of styles as well as colour finishes to choose from, our uPVC windows will perfectly complement the existing style of your home, whether it’s contemporary, art-deco, ultra-modern, a traditional or period property.

Choose from a natural wood effect such as rosewood, light oak, or the classic white; whatever your style, we have the right finish to suit your home. Our colour coatings have been developed in order to bond effortlessly with the UPVC used during the manufacture of your windows, giving an incredibly smooth finish, and providing a protective coating that is low maintenance. Because our UPVC finishes won’t chip or crack you don’t need to worry about re-painting, simply wipe clean.

Colour Options

At Polar Windows we provide a number of glazing options to suit the style of your home, as well as improving your energy efficiency.

We can provide obscure (patterned) glass, available in a variety of different designs that can be used in all of our windows, doors and conservatories, where extra privacy is required, such as in entrance doors, bathrooms or a conservatory side that adjoins your neighbours.

The glass that you use in your windows can help your home be more energy efficient; by using glass produced by Saint-Goban Planitherm (SGP) in your windows you will improve the energy efficiency of your home; reducing you CO2 emissions and saving money on your heating bills. SGP glass is part of the Energy Saving Recommended (ESR) scheme and is more effective than single or standard double-glazing, it will help to:

  • Improve the energy efficiency of your home
  • Reduce the amount of energy you use
  • Save you money on your heating bills

How Planitherm Works
Planitherm is different to standard double-glazing as it works in two ways. It reduces the amount of heat lost through your windows and it also allows more heat (energy) from the sun in through the window. This effect is known as solar gain; as it comes from the sun it won’t cost you a penny!

What’s more, windows containing Planitherm can achieve the EST’s Energy Saving Recommended status, when used with a suitable framing material it will normally achieve a minimum Window Energy Rating of C and can be upgraded to B or A by the addition of Argon gas filling or warm edge spacer bar technology. Planitherm Insulating Glass Units (IGU) are manufactured by approved licensed IGU processors then fabricated and sold through approved registered window companies across the country. Installing Planitherm will help reduce your household’s energy usage and CO2 emissions.

Saint-Gobain Bio Clean:
Saint-Gobain Glass (SGG) Bioclean self-cleaning glass will revolutionise the way you clean your windows; it has been designed for external use, either in the home or commercial buildings, both new build and refurbishment projects including:

  • Windows and patio doors
  • Conservatories, balconies and overhead glazing
  • Glazed facades, exterior shop fronts and display windows, overhead and atria glazing, street furniture
  • Hard areas to reach

SGG Bioclean can be used in all environments and is particularly effective in heavily polluted areas (e.g. near industrial estates and airports) and it must be installed vertically or in an inclined position, the advantages include:

  • The Most neutral self-cleaning glass available – no tint or reflective surface – looks just like normal glass
  • Much easier cleaning – less dirt and grime adheres to the glass
  • Less frequent cleaning – windows stay cleaner for longer
  • Save Money – the cost of window cleaning is reduced
  • Ideal for hard to reach areas
  • Available in a range of colours
  • Permanent coating – lasts the lifetime of the window
  • Environmentally friendly – less frequent use of water and detergents
  • Now available with an advanced performance solar control coating.

How it Works
SGG Bioclean harnesses the power of both UV light from the sun and rain to efficiently combat dirt and grime that accumulates on the outside of the window (dried water marks, organic atmospheric pollutants, dust, sea spray and insect residues). The performance of the self-cleaning action can vary depending on the amount and the type of dirt the windows are exposed to, the total exposure to light and rain the glass will receive and the incline of the window. To activate the coating, the glass must be exposed to natural light for several days; the length of time required will depend on the season and the orientation of the glass.

How long will it take to install my new windows and doors?
It’s hard to confirm exactly how long your installation will take as every home is different. If you are living in a new property it is often easier and can be done fairly quickly, older properties can take a little longer and be more complex, timescales are variable depending how many windows and / or doors we are fitting on that day. The average family home undergoing a complete refit takes roughly 3-4 days, once we know the exact details of your requirement we can provide a more accurate estimate.
