Winter Window Watch: How to Spot (and Stop) Heat Loss Before the January Heating Bill Arrives

Winter Window Watch: How to Spot (and Stop) Heat Loss Before the January Heating Bill Arrives

According to the GFF (Glass and Glazing Federation), a staggering 98% of UK homes are losing energy through underperforming windows. Not only is this a damning indictment of the quality of fenestration in the United Kingdom, but it also highlights the need to make an upgrade.

The rising costs of energy, of course, are not helped by statistics like this, especially as January rolls around again and there’s even more need for properties to make use of their central heating.

See, poorly performing windows allow warm air to escape and for cold air to invade, causing uncomfortable interiors and rises in your heating bills that can be tough to stomach.

How to Spot Heat Loss in Your Windows

There are several indications you might spot in your property to assess if your windows aren’t performing up to scratch.

Cold draughts near windows are telling – feeling cold air when the windows are closed, and noticeable draughts around the window frames, sashes or handles can be common in older installations or poorly fitted systems.

Any sort of condensation between the glass panes can indicate failed double glazing, and moisture on interior glass often suggests poor thermal performance. The effects of such are damaging, as they could contribute to mould, damp, and damage to the windows.

If rooms feel noticeably colder when the heating has been switched on, if areas near the windows are significantly colder than the rest of the room, your windows could be to blame.

How to Stop Heat Loss in Your Windows

There are steps you can take to stop heat loss from your windows and improve the thermal performance that they offer.

In the short term, you could start by improving the seals of the system and their hardware. Replace worn gaskets and ensure that hinges and locks pull the windows tight to the frames.

To secure the future of your property and ensure it remains high-performing in the long run, we recommend upgrading to modern double or triple glazing. Our advanced glazing significantly reduces heat transfer and works hard to keep the warmth inside and the cold out.

Choosing thermally broken aluminium frames is also a wise choice. Thanks to advancements in aluminium fenestration, it’s no longer cold and poor performing as once typically suggested.

Post-Christmas Planning: Why Aluminium Glazing is the Sustainable New Year Resolution for Your Business

The festive season has come and gone, and (hopefully by now) the decorations have been packed away for another year. In Christmas’ wake, businesses are starting to take note of what did and didn’t work for them in 2025. While January is traditionally one of the quieter months, it can often prove to be one of the most important of the year for the planning that well-run businesses make. If you find that sustainability, efficiency and futureproofing top your priorities in 2026, there’s no better time to partner with BDC Aluminium. Turning Post-Christmas Reflection into 2026 Strategy Poorly performing businesses leave it late to act on necessary upgrades, whereas successful businesses assess and plan for improvement in the early, relatively tranquil months. This leaves them in the best position to strengthen their premises, reduce their long-term costs and improve performance across their business. With January often being when budgets are reviewed, maintenance issues are identified, and when a business might look to refresh its sustainability targets, glazing upgrades must be seen as a necessity and a way to modernise your building. Using Your End-of-Year Budget for Strategic Planning If, like many businesses, you end the year with unused capital or deferred expenditure, aluminium glazing is the perfect investment. It improves thermal efficiency and reduces heating and cooling costs, providing significant long-term value as well as an instant upgrade to your property's interior in terms of comfort for customers, visitors and staff members. Even better still, aluminium glazing enhances the aesthetics of your building and supports both sustainability and compliance. If you’re upgrading from commonly used materials like timber, uPVC or steel, you’ll also appreciate the decrease in maintenance your new windows and doors need. . Why Sustainable Aluminium? Aluminium has surpassed all competitors over recent years and has become the go-to option for modern commercial glazing, and it’s easy to see why. From a sustainability perspective, aluminium is unrivalled in terms of sustainability. The metal itself is infinitely recyclable – capable of repeated reusage without any loss of quality. Aluminium’s lengthy life cycle also makes it a much more sustainable and eco-friendly option than timber, which is prone to rotting, warping, and general degradation over time. Our high performance aluminium window products, from the Smart Alitherm 400 range to more traditional Alitherm Heritage range, are perfect for all homeowners looking for a sustainable upgrade. High-performing aluminium glazing systems serve as the perfect upgrade for your business on all fronts, providing drastic improvements in the present and with benefits that last. Plan for a Sustainable 2026 with BDC Aluminium We hope we’ve inspired you to consider upgrading your glazing, and there’s no partner better for your aluminium glazing needs than BDC Aluminium.
