London is home to a range of incredible architectural styles including Georgian terraced houses and Victorian grandeur. Many of these period properties were originally fitted with traditional timber sash windows, adding to the traditional aesthetic of these eras. In today’s modern market, people are looking for the same traditional aesthetics these iconic windows offer, but without the common issues that come with timber such as rotting and warping and costly price tag.

You can achieve this by installing uPVC flush sash windows, a great way to improve both the aesthetics and energy efficiency for your home. These windows offer a sleek and stylish look that can enhance the appearance of any property, while also providing a range of functional benefits that can make a significant difference to your home in London.

Here are just a few reasons why upgrading to uPVC flush sash windows is a great investment for your London home:

With a choice of the standard 4-chamber profile or the supreme Liniar EnergyPlus 6-chamber profiles, coupled with advanced double or triple glazing, Liniar flush sash windows are designed to cut energy bills and household carbon emissions whilst keeping your home a comfortable temperature all year round.

Our Liniar flush sash windows offer superb thermal performance by achieving u-values as low as 1.2- keeping the heat inside your property.

Low maintenance

Unlike traditional timber windows, uPVC flush sash windows won’t warp, rot or fade over time and can be easily cleaned with a simple wipe down. This means you can enjoy the benefits of your new flush sash windows without spending time on cleaning. Our Liniar windows come with a 10 year guarantee as standard, meaning that your new windows are protected.

High security

The security benefits can also be an attractive selling point to potential buyers, helping to make your home more desirable on the market. According to recent research, it has shown that on average the value of homes with newly fitted double glazed windows installed increased by 10%.

Conservation area friendly
