Thermal Performance from Modern Double Glazing in Dartford 

With modern double glazing from First Glaze, you can regain control of the energy efficiency in your Dartford home. 

Older windows allow heat to escape quickly and let cold air in, making your home cold and uncomfortable and increasing your reliance on central heating.

You could be losing up to 10% of your energy through these outdated designs. Why not replace them with our advanced double glazing? 

Our windows and doors feature state-of-the-art double glazing to create a robust thermal barrier for your home. With two panes of glass and weather-resistant uPVC or aluminium frames, you’ll stay warm while using less energy.

The impact of our double glazing on your Dartford home is substantial. Our windows, for instance, can achieve an impressive Window Energy Rating (WER) of up to A+12, making us one of the market leaders. 

Additionally, our double glazing can enhance your property’s EPC rating, potentially increasing its value over time.

Ultimate Security to Keep Your Family Safe

At First Glaze, we believe that your windows and doors should always perform at their best without requiring extra effort from you. However, many older designs demand extensive maintenance. Timber windows and doors, for instance, lack weatherproofing, leading to frame cracks and colour fading over time.

That’s why we offer windows and front doors crafted from durable materials like uPVC and aluminium. These low-maintenance designs ensure longevity, lasting for decades without the need for frequent upkeep. Additionally, if you currently have wooden doors, consider upgrading to composite doors that seamlessly blend modern design with the authentic quality of timber.

When you choose First Glaze, you’re choosing quality products that you can rely on for years to come. We rigorously test every component in our windows and doors before installation to ensure optimal performance. Moreover, our comprehensive 10-year manufacturer’s guarantee ensures that you’re covered in the unlikely event of any issues. With First Glaze, you can enjoy peace of mind and effortless maintenance for your Dartford home’s windows and doors.
