In the modern era, the subject of energy efficiency is of immense importance. That’s why it’s always at the front, back and centre of all our products, from our UPVC windows and aluminium windows to our bi-fold doors, aluminium doors, composite front doors, patio doors, French doors, new fire doors, and conservatories. For many of our customers in East Grinstead and the surrounding areas, energy efficiency and double glazing are relatively unfamiliar subjects.
On this page, our domestic and commercial door installation company explains energy ratings, which differ from Energy Performance Certificates. Energy ratings indicate the efficiency of aluminium windows, aluminium entrance doors, composite doors, double doors, terrace doors, fire-rated doors, and conservatories.
Key things to note:
Here, we specifically look at the window energy ratings, which apply to all products we sell. UPVC and aluminium window frames have their own ratings, but a similar system is in place for bi-fold doors and composite front doors. It is a colour-coded system which can sometimes be a bit confusing because the British Fenestration Rating Council, the British Standards Institute, and CERTASS now operate three separate versions.
Each one sets out to do the same thing, but always check which one you are looking at if you’re judging by the colour alone, rather than the accompanying alphabetical grade.
Prospective customers of our domestic and commercial door installation company should note that energy ratings take into account the frame materials, design, components, and the use of double or triple-glazed windows.
It is simply not enough for windows to have just a good-quality frame build to boost energy efficiency. It is also important that properly fitted double glazing contributes to overall effectiveness. A similar principle applies to the construction of bi-folding doors, French doors, patio doors, aluminium doors, and composite front doors, as well as new fire doors, since they also contain glass.
The rating is calculated by measuring the following:
The rating typically ranges from A to E/G, but the best products will often boast A+ or A++ ratings. We encourage East Grinstead property owners looking to upgrade older windows to seek out higher ratings.
