What are Composite Windows?

Posted by Elevation | Posted Monday, November 5th, 2018 | Posted in Elevation News

If you’re looking for energy efficient windows that offer beautiful design, low maintenance and high security, you will soon find yourself considering the latest composite windows and doors.

These purpose-made products combine an exterior aluminium cladding with a solid timber core. The result is a strong, durable composite window with a low maintenance exterior finish that still offers the charm and strength of wood internally.  Elevation Windows Ltd, as distributors for the Danish company, Rationel, offer a wide range of adaptable styles and specifications.

Composite, or Aluclad, window frames are virtually maintenance free with the aluminium cladding offering both  strength and durability.

These composite windows were initially developed for the demanding climates of Scandinavia so they’re designed to minimise heat loss, with many triple glazed versions  suitable for achieving Passivhaus standards.  Rationel offer both double and triple glazing as standard options and use high quality, sustainable, engineered timber for the internal framework.  Timber is an excellent, natural, insulator which means there is no need to incorporate a thermal break…which is a necessity with an all metal window.

Rationel composite windows are supplied fully assembled, so they’re fully-glazed and factory-finished when they arrive on site for speedy and simple installation.  This has obvious benefits for builders, home owners and architects.

When it comes to achieving a modern look, Rationel composite windows are the natural choice. The modern lines of the powder-coated aluminium cladding are the perfect solution for a contemporary project.  What sets Rationel apart are the design options that will also look comfortable and well considered in more traditional settings.

Dual colour is easily achieved, with no additional cost, so if you want a dark grey outside and a soft white inside – no problem.  Rationel offer most Ral colours, so matching traditional colours is easy…or let your imagination run wild with bold colours.
