Aluminium Windows

Slim sightlines meet new thermal performance – our aluminium window range has been carefully developed to maximise growth opportunities for installers

Alitherm 600 from Smart combines slim sightlines with the latest innovation in polyamide thermal breaking technologies in a residential and light commercial aluminium window, which is proven to perform.

With a choice of either 70mm or 53mm frame depth this includes a WER B Rating and u-values as low as 1.3W/m2K.

Available in ovolo, chamfered or square detailing and dual colour options, Alitherm 600 offers a high degree of design flexibility replicating the subtleties of traditional casement windows to statement contemporary installations.

All finishes are to a marine-grade quality polyester powder coat – as standard.
