Environmentally Friendly Double-Glazed Windows

Associations & Accreditations

Most of us are trying to minimise costs and at the same time care for the environment. These two aims need not be mutually exclusive. Our range of eco double-glazed windows is good for the planet as well as your bank balance.

You’ll only be truly eco aware and save money if you choose the right double-glazed windows from a reputable supplier. New double-glazed windows are a significant cost but simply buying the cheapest won’t achieve your aims. Instead, treat the purchase as an important investment that will serve you well for many years if you make the right choice.

The Benefits of Sustainable Double-Glazed Windows

It is estimated that as much as 40% of heat loss is through doors and windows. However, this will only occur if you have old, single-glazed windows that aren’t efficient. To measure how effective new windows are, you need to be aware of three factors:

  • The thermal efficiency, which is expressed as a U value — a measure of how much heat is transferred from one side of a window to the other. A low U value indicates minimal heat transference, which will result in a warmer home in winter and a cooler one in summer, so you achieve all-year-round comfort.
  • Solar heat gain is measured as a value abbreviated to SHGC, this indicates the amount of heat from the sun’s rays that passes through the windows. Although a high value can be useful in winter to provide natural heat, it may not be so welcome in summer when you want to keep the house cool.
  • Air leakage (or draughts) applies to old or badly fitted windows and can cause discomfort in the home. The key is to look for window systems that will reduce the air transfers through the openings. Typically a system with a hinge and a gasket seal will do this better than a double glazed sliding windows system.

Eco-friendliness in windows is achieved in many ways, including using materials from sustainable sources and those that are recyclable at the end of their useful life. Top-quality windows with high thermal efficiency will also significantly reduce your energy use due to a lower reliance on artificial heating in winter and air conditioning in summer. This not only reduces emissions and the use of resources but will also save you money throughout the year.

Over the whole course of its life, an eco double-glazed window will more than pay for itself due to the savings you will make. These not only comprise the reduction in energy bills but also the long life of our products that means replacement will be required much later than for cheaper, inferior products.

Eco Windows for a Sustainable Future

Since energy prices will continue to rise and sustainability becomes ever more important, installing our eco double glazed windows is an investment that you won’t regret. Our emphasis is always on supplying the highest quality windows and installing them properly, so they perform at peak efficiency.

We offer custom-made windows, so they fit precisely with no gaps. Combined with the specially treated glass with argon gas between the panes and frames with effective seals, they have high thermal efficiency. As a result, they will help to keep you comfortable the whole year round and will save on energy costs at the same time. You can rest easy knowing all our new window installations are compliant with the 7 Star Energy Rating required under the Nationwide House Energy Rating Scheme. If you care about the planet and want to save on energy bills, contact us today to see what we can do for you.
