With this in place, you can rest assured that you’ll be bringing a worthwhile investment to your home that will serve to stand the test of time: even after prolonged use and exposure to the elements.

Highest Level of Security

We know that feeling safe and secure in your property is one of the defining factors that enable it to feel like home.

uPVC Slimline Window Features

The cutting-edge profile of our slimline windows works to break up convection currents, trapping in pockets of warm air to keep your home heated for longer. By combining this profile with high-performance weather gaskets, they are able to achieve an A+ rated standard of thermal efficiency to keep you comfortable across the year.

Not only will this increased degree of heat retention work to keep the winter winds at bay, it could also help you to save money on your heating bills. The energy efficiency of the windows ensures a lowered reliance on your central heating to keep your property warmer, which in turn could help you to cut your heating costs and lower your carbon footprint at the same time.

The inherent design of our slimline windows allows them to achieve a stylish look without compromising on performance. Due to the use of premium grade materials, our slimline windows achieve a beautifully slim frame without reducing the overall structural integrity. With this in mind, you’ll be able to enjoy the best in function and form.

Slimmer frames also work to create a brighter and more spacious feel in any room that they are installed into. The larger glazed area allows a generous amount of natural light transfer into the room. Our windows are the ideal way to bring the outside in, while keeping the elements out.

Due to modern manufacturing techniques and premium grade materials, our slimline windows are able to achieve an impressive lifespan. For your peace of mind, they are accompanied by a comprehensive 10-year guarantee to ensure they continue to bring lasting satisfaction long after they are initially installed.

The modern uPVC used in their manufacturing process allows our slimline windows to avoid the problems that usually accompany the timber material. This means that you can avoid any cracking, warping, discolouring, twisting, or bowing out of shape that can happen when different materials get wet or age.
