Thermotech | Sash Windows in the South of Wales

Sash Windows

Sash windows are renowned for being elegant and in keeping with your traditional property. They also come with a hefty price tag. To combine the stylistic benefits of traditional sash windows with the functionality and cost of casement windows, then uPVC sash windows are the answer! What makes uPVC sash windows a viable choice for your property?

Suitable for different types of property

Aiming to replicate traditional sash windows, you may think the uPVC replacement option is only suitable for vintage properties. Think again! The functional and maintenance benefits of Thermotech’s uPVC sash windows make them suitable for anyone wanting to add a touch of elegance to their home, without adding a touch of emptiness to their bank account. Not only are they more secure than traditional wooden frames, they also prevent heat escaping, rain getting through cracks and window maintenance being a constant niggle in the back of your mind.

Helping the environment outside and inside your home

Modern replacement uPVC sash windows are stylish and good for the environment. In this way they are one of the best replacement window options. Innovative design means that they vastly improve heat retention and reduce escaping heat.

In traditional timber styles, heat can be lost through draughts and rainwater let in through cracks. uPVC sash windows don’t share these problems, as they are installed using subtle but state-of-the-art weather proofing agents for maximum effect. Not only can you save on window installation by buying this option, but you will continually save on heating bills and reduce the carbon footprint of your home.

Versatility without the maintenance worries

It is no wonder that sash windows are ever increasing in popularity – modern versions combine style and function. Those from Thermotech boast versatility and reduced maintenance. Our uPVC sash windows are easy to clean and use an innovative operating system. These windows are designed to slide vertically, either downwards or upwards.

Compared to standard sash windows, these windows are much more versatile and don’t require constant attention to rotting or warping. uPVC sash windows are much more durable due to their resistance to corrosion and weathering.
