Slimline Windows that Transform Your Home

As a leading home improvement company in the South West, at DM Windows we recognise the importance of constantly evolving with changes in technology and demand. One product that has shot to popularity in recent times is slimline windows.

Slimline windows are windows designed with a minimal frame profile, with the frame itself being extremely thin. This allows for a larger glass area, especially popular for the high amount of natural light that can enter a room. DM Windows install slimline windows with aluminium and uPVC frames, depending on your individual preference and requirements. Operating across Bristol, Bath, Somerset, and the surrounding areas, we possess years of industry experience and pride ourselves on exceptional customer service, quality installations, and competitive pricing.

Thrive with the mental and physical benefits of exposure to natural light

For many, the reason behind installing slimline windows is the amount of natural light that they allow to effortlessly flow into your home. Regular exposure to natural light is proven to have several mental and physical benefits, with the first being an enhanced connection with nature – which can have a positive impact on wellbeing whilst reducing stress levels. In addition, as our screen time continues to grow both in our personal and professional lives, having a plethora of night light entering your home reduces strain on your eyes.

Regular exposure to sunlight, which slimline windows help achieve, is also proven to boost energy and improve your sleep quality, as well as increasing productivity. All things considered, it’s not just your home’s aesthetic and kerb appeal that will benefit from slimline windows, but your loved ones too.

Slimline window frames in a variety of materials

At DM Windows, we install exceptional slimline windows with frames made from either aluminium or uPVC – the choice is yours.

Aluminium

Aluminium is an incredibly strong but lightweight material, enabling a slim frame to support large panes of glass. It’s also very durable, easy to clean thanks to its non-porous surface, and aesthetically pleasing, as the slim sightlines provide a contemporary look.
Aluminium profiles can be finished in a range of RAL colour options and styles to help create your dream windows, whether you're looking to enhance a new build, or older properties.

uPVC

uPVC is another great choice for a slimline window material. Strong despite being slim, they can withstand harsh weather conditions and avoid warping or bending, with their narrow frames allowing for a large amount of natural light intake. They’re also incredibly thermally efficient, helping to trap heat inside during winters and keep the house cooler in summers. It’s also an affordable option, due to its ability to be produced in bulk.
