Energy Efficient Flush Casement Windows

With energy prices continuing to soar, we know how important it is to try and lower your bills and save money. Much of the warmth we generate from our central heating is lost through inefficient windows and doors, so they are an ideal first place to start when considering home improvements.

In these modern times, it’s never been more vital to keep on top of your energy costs. With bills rising, flush casement windows can be a real help. Thanks to their double glazing and water-tight frames, our windows can maintain your home’s temperature without needing your central heating.

As well as that, cutting down on your energy usage can also make your home greener. With a reduced carbon footprint, you can do your bit to help our planet. Not only that, but VEKA use recycled uPVC so that your windows are also environmentally friendly.

Flush Casement Window Security

At Thermaframe, we know how important it is to make you feel safe in your home. That’s why we put security first in our flush casement windows. Thanks to our partnership with VEKA, your windows will contain security features that are a nightmare for unwanted visitors.

With multi-point locking mechanisms as standard, you can secure your home effectively. Additionally, the frame conceals most of the hardware so you won’t miss out on outstanding views and natural light. That way, you can enjoy a bright and airy living space with valuable peace of mind.

Areas We Cover

We are proud to offer high-quality home improvements for all homes throughout Caterham, Sevenoaks, Tonbridge, Tunbridge Wells, East Grinstead, Kent and Surrey. Whether your home is modern or traditional, we’ll be able to accommodate. Get in touch today for our highly competitive double glazing prices.
