About us

At WindowTreat we’ve been at the forefront of innovative window treatments since 2006. We’re experts in finding bespoke solutions to some of the most common problems associated with glass, in the home and in commercial environments.

We’ll work closely with you to find the right solution for your needs – whether you’re looking for solar window treatments for comfortable living or a more productive workplace, you want to increase the thermal efficiency of your glazing and reduce your energy costs, or you want to ensure maximum security against intruders or potential attacks. We also provide specialist energy and bomb blast modelling, so you can see for yourself how you’ll benefit from our products.

Our revolutionary window solutions, attention to detail, flawless delivery and award-winning leadership team set us apart. We pride ourselves on our project management and open, honest communication at all times.

We’re highly experienced in a wide range of projects, both big and small, and we strive for excellence in all we do – from our advice to our modelling and our installation. We know trust needs to be at the heart of any working relationship, and we’re passionate about making our customers happy and delivering results that work. We don’t take shortcuts, or believe in off the shelf solutions. We take time to understand your problem and make sure we deliver the perfect outcome for you.

All of our products and installations go through rigorous quality control, and our window treatments and our workmanship have preferential warranties, so you can have complete confidence when you choose WindowTreat. 

What Our Customers Say About Us

"I'm very pleased I can use the room all the time, even in hot temperatures". 
- Jennifer, Didcot

"Just had window film installed in my conservatory and already the heat is reduced. Excellent job, installers professional and polite - and tidied up after themselves." 
- Elaine, High Wycombe

"WindowTreat had the best understanding of our glazing systems and how their products would perform. We have definitely noticed a reduction in solar gain and glare and as a result we are much more comfortable.  Delighted!" 
- Philip, London

“The difference in glare and intensity of heat was immediate and I am now able to sit in the conservatory comfortably in the afternoon when the sun is shining. It is such a transformation.” 
- Shalesh, Basingstoke

  • Ellen Lister

    “The operations manager Chris Gargett contacted me, and asked some questions about my conservatory and recommended the type of film to have fitted. He was very polite and knowledgeable of the products he offered. The installation was very professionally done, the chaps were polite and very tidy while working, and cleared up afterwards.”

  • Alain Roux

    We have been delighted with the performance and quality of the product plus GP Systems’ professional service from initial enquiry through to the single seamless, hassle free fitting achieved in one short visit.
