Preparing For Winter: The Importance of a Thermally Efficient Home

Learn More Contact Us

We’re sure you won’t need reminding, but winter is fast-approaching. The nights are dragging in, and the days will soon start crisp and cold, leading to frosty evenings. There’s even the potential for snow! Something that we all yearn for but despise when it arrives.  

Something that’s always worth reminding people of, though, is the importance of thermal performance. More specifically, the thermal performance of your home. And something you might not know, is the integral part your front door and windows play. 

Join us as we raise awareness of the importance of a thermally efficient home, and the huge role that your windows and doors have in making sure that you and your loved ones, and your bank account, are protected from a potentially harsh winter ahead.

Why You Should Invest in a Thermally Efficient Home

Let’s start with the basics. When the cold months come back around (too fast for our liking), your home should be a reprieve from the bitter weather. If your home’s thermal performance isn’t up to scratch, you may find yourself spending the entire winter layered up and shivering. 

If your home’s thermal performance is high, you’ll suffer from the cold much less. You’ll save money on your heating bills as a bonus, as there’ll be fewer occasions when you need to put it on. 

Having a thermally efficient home also has environmental benefits. The less you need to put the heating on, the less energy you’ll use. Most homes in the UK are still powered or heated by gas and electricity from non-renewable sources. So, less heating equals fewer carbon emissions. 

Superior Thermal Efficiency with Low U-Values and InsuLock Technology

Now that you’re aware of the importance of thermal efficiency, you’ll be pleased to hear that we design all our products with the performance of your home in mind. 

Take our revolutionary InsuLock technology, for example. It offers almost double the insulation of traditional polyamide thermal breaks, which are what is most used in other aluminium window and door systems. It’s designed specifically to handle the ever-changing UK weather conditions, and it’s at the heart of every Endurance Aluminium product. 

It contributes to the low u-values we can offer. In case you didn’t know, u-values are a measure of thermal transmittance, which essentially describes how much heat is transferred through something. So, lower u-values mean better thermal performance. All our double-glazed products comply with Part L regulations and achieve u-values of 1.4 or lower. Opt for upgraded triple-glazing, and you could enjoy values as low as 1.0.
