Benefits of Our uPVC Sash Windows


Thermally Efficient

Featuring a multichambered profile, our uPVC sash windows are extremely thermally efficient. The profile actively works to trap and retain heat throughout even the coldest months. With this, pockets of air will prevent any cold transfer in. Combined with robust double glazing, your home will remain a consistent temperature.


Heritage Features

Because of their authentic appeal, our sliding sash windows are the perfect addition to a new build in Polhill that is looking to add rustic allure. Alternatively, they are also suitable for true heritage properties. Opting for a modern product does not need to mean you lose the authentic heritage feel!


Bespoke Designs

uPVC is a highly customisable material by nature. With this, we are able to provide our sash windows in a range of different colours, foils and finishes. With Thermaframe, the design possibilities are endless! Whether you are looking to reinvent the style of your Polhill home or retain its existing style, our design team will help you make the decisions to meet your needs.


Range of Colours

With our vast palette of RAL colours available, our uPVC sash windows come in more colours than our competitors. With this we are able to offer windows that are bright, bold, neutral or pastel. If you have a vision in mind, no matter how unique it is, please let us know. Our team love a challenge!


Low Maintenance

Made from durable uPVC instead of timber, our sliding sash windows require minimal maintenance. While timber windows are known to warp, crack and distort after exposure to wet weather, uPVC will not. It will remain robust and strong. With this, you will not need to repaint or varnish your new additions.


Stunning Sightlines

Enjoy vast views out of your new windows thanks to their slim sightlines and vast panels of glazing. In the winter, stay cosy inside and watch the snow fall. In the summer, keep them open and let the summer air circulate your home!
