Klosen UK: bespoke aluminium for residential and commercial projects

Klosen UK presents itself as a professional installer with over 25 years of experience in supplying made-to-measure aluminium doors and windows for both residential and commercial properties. The company works with architects, builders, designers and homeowners to adapt its systems to new-build projects and traditional homes, with a particular presence in Peterborough and Cambridgeshire.

Its range is based on European profile brands, including Cortizo and Senior Architectural Systems, and on the option to choose between double or triple glazing on all its installations.

Aluminium doors

The door catalogue includes hinged, sliding and bifolding solutions, as well as entrance doors and slimline profile models. The company selects designs from European manufacturers to offer a variety of finishes and opening mechanisms, aimed at maximising natural light and views without compromising thermal insulation. Among the types listed are aluminium doors, bifolding doors, sliding doors, slimline sliding doors, slimline bifolding doors, entrance doors, patio doors and doors from the Cortizo and Origin brands.

Windows and curtain walling

The window range covers slimline aluminium profiles, heritage-style windows, casement, tilt & turn, flush, fixed, thermal break windows and double and triple glazed versions, with options for opening mechanism, frame finish and glass thickness. The company also sells windows from the Cortizo, Origin and SAS brands, and completes its offer with rooflights and skylights: made-to-measure flat roof windows, aluminium lantern rooflights and pyramid rooflights. For commercial projects it offers automatic doors and aluminium curtain walling.

Projects and media coverage

The company publishes case studies and completed projects, and notes that its Cortizo windows featured in a Grand Designs project in South Lincolnshire in January 2021, a home inspired by a Dutch barn in which a modern look and good insulation were sought. Among the published testimonials, customers describe the installation of several windows and sliding doors on a new build, as well as the supply of three large sliding doors after another supplier had previously cancelled.

Coverage and working process

Klosen operates from its base in Market Deeping, Lincolnshire, and usually covers a radius of around 60 miles, with a presence in towns such as Bourne, Stamford and Huntingdon, as well as London. The company states that it serves both rural settings and urban centres, from Camden Mews in London to Weston Hills in Lincolnshire. Its working method covers initial design and planning, measuring and requirements analysis, and final installation, with the stated aim that the customer is satisfied with the progress of the project.

Quotations, lead times and maintenance

The company offers free, no-obligation quotations, and explains that the price depends on the area to be covered and the designs chosen, as every window and door is made to specification. The site indicated lead times of around five or six weeks for the supply and installation of most of its products, with longer lead times possible in some cases. It recommends a prior survey of the property to advise on the most suitable products and to verify measurements. It also offers door and window maintenance services, and has downloadable brochures and a comparison between aluminium and PVC.
