flush windows
Clean lines, timeless style and modern performance
Whether you’re upgrading tired windows or starting a new extension or development, flush windows offer the perfect balance of form and function.
Why you should consider flush windows for your home:
If your current windows are bulky, uneven or starting to look tired, flush windows offer a refined, efficient alternative. They combine elegant styling with advanced materials, helping you get more from your home.
Whether you’re upgrading as part of a window replacement project or planning a full redesign, flush frames offer a sleek solution that enhances both form and function.
With flush-fitting frames that sit level with the sash, they create a streamlined finish that suits both heritage homes and modern builds. Available in uPVC, aluminium, and timber effect options, our flush windows are designed to elevate the look and performance of your property. You can explore our full range of styles on our windows page.
- A Cleaner Look
Slim frames and flush-fitting sashes create a smooth, modern finish that sits neatly within the frame. - Improved Security
All flush windows come with multi-point locking and high-spec hardware as standard. - Energy Efficient
Options like multi-chambered profiles and triple glazing help reduce heat loss and lower energy bills. - Low Maintenance
Modern materials mean no more painting, warping or peeling. Just long-term durability with minimal effort.
Over 200+ happy client reviews
A great family run company based in Kent, but operate in a wider SE area. They did an excellent job for me in East Sussex replacing three windows: competitive, high quality windows and professional installation. A very friendly and professional company.
– Richard Eden-Green
From quote to post-install checks, everything went pretty smoothly and all those involved (Will, Seb, Sean and Dave) were polite, efficient and fixed any issues that arose quickly and well. The windows look great, are supposedly slightly higher (A+) efficiency than some competitors and have reduced the noise in the house a lot. Highly recommend.
– Stephen Casey
I found House of Glass brilliant to deal with. I needed my windows in a hurry and they delivered without any issues. The windows look great and we are very pleased with them. The team at House of Glass were very professional, friendly and I found the whole process from ordering to installation very easy. Thank you House of Glass. I would happy recommend them to anyone.

The sales staff has full knowledge of the window production and also provided related advice on home refurbishment. He quote is comprehensive. I did not choose the company because of price.

Frequently asked questions
Got a question? We’re here to help! Below you’ll find answers to some of the most common queries about our flush windows, installation process, and services. If there’s anything else you’d like to know, please don’t hesitate to get in touch with our friendly team
Are flush windows suitable for conservation areas?
Yes. Our Residence Collection flush windows are designed to replicate traditional timber, making them a great choice for period properties and conservation areas. Always check with your local authority, but many customers have had these approved with no issue.
Do flush windows only suit modern homes?
Not at all. While aluminium flush windows look fantastic on contemporary builds, uPVC and timber effect flush windows can be styled to suit everything from cottages to Georgian townhouses.
What’s the difference between flush windows and standard casement windows?
Flush windows have sashes that sit level with the outer frame, creating a cleaner, more streamlined appearance. Standard casement windows usually have a stepped look where the sash protrudes slightly.
