Timber Composite windows: ALDUS, Rationel AURAPLUS, Rationel FORMAPLUS

Rationel Windows (UK)

ALDUS – a window that keeps itself in balance for many years
ALDUS are energy-efficient windows and doors in timber/aluminium, made of a sturdy construction, with external aluminium cladding attached with clips. The cladding adds to the protection against wind and weather. This means natural timber on the inside and easy maintenance on the outside, year after year. ALDUS is especially suited for modern residential construction and renovation of detached houses from the last 30-50 years.

Rationel AURAPLUS – a winning window now and in the future
Our new slimly designed Rationel AURAPLUS range has many excellent features which benefit both people and the environment. They contribute energy – up to +31 kWh/m2 annually – by letting more sunlight – and thus free heat – in and not out. This means significantly reduced heating bills during the heating season as well as significant carbon dioxide savings for the family. In addition, draughts are minimised and cold air prevented from falling, to ensure a more comfortable and healthier indoor climate. Rationel AURAPLUS won the Danish Building Industry Energy Award 2010.
Rationel FORMAPLUS - the window that requires a minimum of maintenance
Rationel FORMAPLUS is made of a sturdy construction with external aluminium cladding attached with clips, which makes the window extremely resistant. This means natural timber on the inside and easy maintenance on the outside. Rationel FORMAPLUS is especially suited for refurbishment of older buildings but is also ideal if a classic façade appearance is desired.
