The Contemporary Rationel Range


For outstanding architectural elegance and energy efficiency look no further than AURA and AURAPLUS triple-glazed windows and doors.

Their sleek, minimalist design and superb optical clarity is ideal for creating extensive glazed areas that let in maximum natural daylight for a pleasant modern living environment.

With its high performance triple-glazing, AURA and AURAPLUS can easily achieve the Passive House standard of energy efficiency, dramatically reducing your CO2 emissions and energy bills.

The AURA range is constructed from solid timber offering all the beauty of a natural wood finish. AURAPLUS timber composite windows have durable exterior aluminium cladding, which provides extra protection against the harshest of weather conditions and requires zero maintenance.

Both AURA and AURAPLUS ranges offer a wide variety of different styles, colours and additional glazing options to suit your project.

Energy Efficient Triple Glazing

AURA and AURAPLUS are in the forefront of modern energy-optimised windows and doors.

With high performance 52mm triple-glazing provided as standard, AURA and AURAPLUS windows achieve U values as low as 0.79, which is ideal for low energy buildings and Passive House construction.

All triple-glazed units are constructed with argon gas insulation between the panes and a warm edge spacer or ‘thermal break’, which reduces heat loss round the perimeter of the window.

In fact, our energy-optimised glazing can let in more free solar heat than is lost through the window, which significantly reduces the energy consumption required to heat your home during the winter.

With AURA and AURAPLUS you can be certain to enjoy a more comfortable living environment with no drafts or cold spots.

All Rationel glazing been approved according to the EN 1279.
