What Are Slimline Aluminium Windows?

Slimline aluminium windows are characterised by their ultra-narrow frames and offer significant advantages over uPVC options.

Their slim frames maximise the glass area, providing extensive views and abundant natural light. The natural strength of aluminium contributes to an impressive lifespan of up to 45 years, exceeding the typical lifespan of uPVC windows by over a decade.

Sleek and modern, slimline aluminium windows offer an excellent option for contemporary homes. Their aesthetic can also rejuvenate older properties, providing a fresh, updated look with enhanced insulation.

Klosen offers customisable design elements to complement any home, including various opening styles (or fixed panes), modern locking systems, and a wide selection of handles for tailored security and style. The colour and finish options are extensive, spanning from popular greys and blacks to bolder metallics and soft pastels.

Why Choose Slimline Aluminium Windows for your property in Leicestershire?

If you have a property in the city of Leicester, such as in Clarendon Park, Knighton or Stoneygate, these windows offer plenty of benefits, including increasing the amount of natural light while reducing noise pollution.

Known for its idyllic countryside views, if you’re lucky enough to have a home in rural Leicestershire, slimline windows allow you to expand your views. It’s an ideal way to bring a modern, yet sensitive upgrade to cottages and heritage properties in beautiful locations such as Charnwood Forest.

Slimline aluminium windows offer a stylish appearance, superior thermal efficiency, and a longer lifespan than uPVC and timber options. These windows are also highly customisable, with popular choices for modern renovations including black aluminium windows and white aluminium windows.
