Benefits of our uPVC Sash Windows


Thermally Efficient

As mentioned, our windows are incredibly energy efficient. A multichambered profile assists in the trapping and retaining of heat. You will find your living space stays warm during the winter months, preventing the need for central heating. This makes our sliding sash windows an extremely cost effective purchase – you will find yourself saving money for years to come on energy bills.


Heritage Features

Our authentic design sliding sash windows are the perfect installation for heritage properties, or to simply add rustic charm to a new build. Having a heritage home and needing new windows does not have to mean you will lose the authentic heritage feel when you work with Thermaframe. Select a window style that will simple enhance this aesthetic.


Bespoke Designs

uPVC sash windows are extremely versatile. This is partly due to the nature of uPVC as a material, but also due to our endless design opportunities. Whatever it is that you are looking for, we are confident that we will be able to create and install it. Choose from our range of colours and customisable hardware and create your dream sliding sash windows.


Range of Colours

At Thermaframe, we have a vast palette of RAL colours for our valued customer’s to browse. Whether you are looking for something neutral, pastel, bright or bold, we will be able to create it. Authentic woodgrain foils can be used if you prefer a natural look. Improve your property’s kerb appeal with our uPVC sash windows.


Low Maintenance

As our sliding sash windows are made from uPVC instead of traditional timber, they require minimal maintenance. Unlike traditional timber profiles that warp and crack after exposure to wet weather, uPVC sash windows will not. They will not need to be varnished or painted. A simple wipe down every now and then will keep them looking brand new.


Stunning Sightlines

Enjoy vast views of your outdoor area after the installation of our sliding sash windows. Their slim sightlines allow natural light to floor your Orpington home. During the winter you can sit inside, cosy and warm, and watch the seasons pass by.
