Aluminium Clad Composite Sliding Doors

Here at QBD we’re proud to supply both VELFAC & Rationel sliding doors. Both companies were founded in Denmark in the 1950’s and now part of the DOVISTA Group of leading window and door companies, and every year makes and delivers over 350,000 windows worldwide.

VELFAC & Rationel composite doors combine low-maintenance external aluminium with natural internal timber, and are renowned for their contemporary style, impressive durability, excellent insulation, and secure and sustainable design. The slim frame maximises natural light, and uniform sightlines give every unit an identical external appearance.

VELFAC sliding doors combines durable external aluminium internal timber. By placing the moving aluminium sash in front of the fixed timber frame the window delivers a ‘floating sash’ effect. You can choose single or double sliding doors depending on the space available, making your patio door unique to your home. VELFAC offers a lift and slide tilting door, to ensure when the door is closed the sightlines match the products across the VELFAC range.

Proven to withstand the most extreme weather conditions, the external aluminium frame never needs repainting for the lifetime of the installation.

VELFAC windows offer U-values as low as 0.8W/m2K for triple glazed units. The slim frame contributes to excellent thermal insulation, as glass is a better insulator than the frame.

The standard VELFAC frame features polyester-powder coated external aluminium and painted or lacquered internal timber. The frame can be finished in different colours inside and out in any of the full range of RAL colours.

Rationel sliding patio doors are designed to be as beautiful as the outdoor view they frame. Highly-energy efficient, they work to bring the beauty of your garden into your home but keep the heat and enjoyment throughout the winter months.

Rationel sliding exterior patio doors are available in the AURAPLUS triple glazed range. This unique profile is characterised by clean lines and a sleek frame, with additional aluminium cladding externally for exceptional durability and a life expectancy that will span decades.

With over 200 colours to choose from, and the option to have a different colour inside and out, your sliding doors will be truly bespoke to your home.
