How to Improve Window Insulation for Winter

As temperatures drop outside, insulation understandably becomes a big topic. The best way to up the insulation in your home is to replace any old, inefficient windows with high-quality double glazing.

And if your home is already benefiting from windows with a low U-value (this means they are energy efficient), you can still take some steps to improve their performance even more, which will in turn save you money on heating bills.

Our team of experts have written this blog to help you get the most out of your windows during winter and beyond.

When it’s Time to Replace Your Older Windows

It’s a clear indication that your windows aren’t performing well if you’re seeing condensation in between your window panes, you’re experiencing consistent draughts, and your home is taking a long time to heat up.

Warped frames, cracked glass, and stiff hinges are also common signs that it’s time to replace your current windows.

Reduce heat loss and boost comfort within your home by replacing these poorly performing windows with energy-efficient windows from a reputable window installer.

Window Replacement vs. Window Insulation

Only insulating your older windows without replacing them won’t have a huge effect on their long-term energy efficiency, as it’s just a short-term fix. This is especially true if you only have single glazed windows as they can lose heat faster than insulation alone helps.

In this situation we would recommend a window upgrade so you can really get the benefit of increased warmth, less draughts, and lower bills.

Energy bills still remain at a high level, which means an energy efficient replacement can help cut your bills to a more manageable level. While they are an initial investment, they can pay for themselves in lower bills every month.

How to Increase Window Insulation

Even if your windows are doing a good job, it’s still worth looking into additional insulation for the winter months – so you can save as much money on your heating bills as possible.

Window Film – Easy to remove and quick to apply, window film works by adding a clear, insulating layer to the glass. It can reduce heat loss by up to a massive 30%.

Thermal Curtains & Blinds – Alongside enhancing your interior style, thicker fabrics help prevent cold air from entering your home.

Caulking & Weatherstripping – Ideal for sealing small gaps around frames, these simple measures can significantly reduce draughts before they become a problem.

Bubble Wrap Insulation – A low-cost, temporary solution that helps limit heat loss, particularly useful in rooms that are used less frequently.

Secondary Glazing – Well suited to traditional or period properties, including those in listed areas. This option adds an extra layer of insulation and also improves sound reduction.

Draught Excluders & Insulation Tape – A practical, budget-friendly way to close minor gaps and support overall energy efficiency.
