Rationel is one of Europe’s leading window and door brands, supplying high quality windows to homeowners across the UK. Rationel offers two styles of windows for your home improvement window replacements: Auraplus and Formaplus.

Auraplus are the ideal window replacement solution for contemporary and modern homes. With their slim sightlines and sleek, minimal frames, Auraplus windows are a beautiful addition to any property. These windows are also made to last, with a long life expectancy of 83 years due to their external aluminium cladding. Auraplus windows also boast great thermal efficiency and noise reduction due to their excellent insulation.

Formaplus windows are the perfect addition to traditional homes, as they are designed to complement British architecture. The design of Formaplus windows with elements such as angled glazing beads and bevelled edges bring a timeless charm to this window style, perfect for classic homes. These windows are timber frames inside an aluminium covering, offering your home more thermal efficiency compared to traditional timber frames, which may rot or warp in severe weather conditions. They also come with multipoint locking systems throughout the window frame, giving you peace of mind when upgrading your home.

Rationel windows are customisable to your home’s needs and your personal aesthetic taste and can be created specifically for the measurements of your home, so the windows supplied to your home are perfectly fitted.

Here at ecoHaus, we supply Visiline ALU5 and ALU6 Windows with multiple designs available.

Visiline ALU5 and ALU5 View windows are perfect for newly built homes or modern renovations to pre-existing homes. The ALU5 range offers an airtight design with a triple gasket system to create an airtight barrier around the window, improving your property’s energy and thermal efficiency and reducing noise by creating additional soundproofing. The ALU5 View range comes with a hidden sash, allowing for slimmer sightlines for a better external view from the window and allowing you to open your home up to the outdoors with ease. Both ALU5 ranges can be personalised to your home’s needs and aesthetic, have been created with durable materials for long life and are low maintenance.

The Visiline ALU6 and ALU6 View ranges boast minimal sightlines for natural light enhancement and are triple glazed for your energy and thermal efficiency needs. Triple glazing ensures heat is kept within your home during the winter, and it is also fitted with a triple gasket system to stop heat from escaping from the window frame, similar to the ALU5 ranges. The ALU6 ranges are also compliant with PAS Security standards and can be designed to your home’s taste and aesthetic, ensuring all projects we complete with Visiline windows leave our customers satisfied.
