As the cold of winter sets in, January often brings the unwelcome shock of high energy bills. If you’re looking for a cost-effective way to improve your home’s insulation, reduce heating costs, and enjoy a quieter environment, secondary glazing systems could be the solution you’ve been searching for. At Windrush Doors and Windows, our specialist glazing services help homeowners make their properties more comfortable and energy-efficient, without breaking the bank.
What is Secondary Glazing?
Secondary glazing involves adding an extra layer of glass or acrylic inside your existing window frame. Unlike full window replacement, secondary glazing is minimally invasive, more affordable, and highly effective at improving thermal insulation.
Benefits include:
- Enhanced insulation: Keeps heat in during winter and prevents drafts.
- Reduced noise: Ideal for homes near busy roads or schools.
- Lower energy bills: Improved insulation reduces the need for constant heating.
- Preservation of original windows: Perfect for period properties or listed buildings where full replacement isn’t possible.
Why Choose Specialist Glazing?
Installing secondary glazing systems requires precision to ensure a perfect seal and maximum efficiency. Our team at Windrush Doors and Windows are specialist glazing professionals, trained to fit all types of secondary glazing, including:
- Sliding or hinged panels for easy cleaning and access
- Acoustic panels for maximum noise reduction
- Custom solutions for unusual window sizes or shapes
With the right installation, secondary glazing can significantly reduce heat loss, often cutting energy bills by up to 25% in older properties.
Tips to Keep Your Home Warm in a Cost-Effective Way
While secondary glazing is a long-term solution, there are simple, economical tricks you can use alongside it to stay warm this winter:
- Use draft excluders
Fit draft stoppers to doors and windows to prevent cold air from sneaking in, especially around old frames. - Seal gaps and cracks
Inspect window and door frames for small gaps. Silicone or foam sealants are cheap, quick, and highly effective. - Heavy curtains and thermal blinds
Thick curtains trap heat, while thermal blinds offer additional insulation without blocking natural light. - Rugs and carpets
Bare floors can make rooms feel colder. Adding rugs helps retain warmth and makes your home cozier. - Smart heating strategies
Lower your thermostat slightly but use timers or smart controls to heat rooms only when needed. Even 1–2°C difference can save money without compromising comfort. - Reflective radiator panels
Installing reflective panels behind radiators ensures more heat is directed into the room rather than escaping through walls.

Make Your Home Warmer, Quieter, and More Efficient
Investing in secondary glazing systems is one of the most cost-effective ways to tackle winter cold, reduce noise, and lower energy bills, especially in older properties with single-glazed windows. Combined with simple home insulation tricks, it’s possible to enjoy a warmer, more comfortable home without spending a fortune on heating.
At Windrush Doors and Windows, our specialist glazing team can assess your property, recommend the right secondary glazing solution, and install it to the highest standard, ensuring your home is ready to face the winter chill.
