Aluminium Windows

Our aluminium window range is a great alternative to uPVC. Ecotherm 50 aluminium windows offer slim sightlines, excellent thermal efficiency and lots of design options, so they’re the perfect range for the trade to offer to homeowners.

Aluminium is a great choice for domestic projects that want sleek, sophisticated style, with high-performance.

With more consumers choosing to fit their homes with aluminium bi-folding and aluminium sliding doors, offering aluminium windows gives them the chance to match their windows and doors across the property.

Because of the inherent strength of aluminium, slimmer sightlines can be achieved, for a larger glass area to maximise the daylight levels in any property.

Plus, aluminium windows have great thermal efficiency and security benefits.


Ecotherm 50 aluminium casement windows manufactured by Everglade offer comfort, warmth and style to all properties.

Available with double or triple glazing, Ecotherm 50 windows also use thermal break technology for low U-Values and improved efficiency.

The windows have been fully tested up to 1200pa for water tightness and 2400pa for wind load.

There are plenty of design options available, with casement and French casement opening styles, a full colour range and a choice of hardware options.

Plus, homeowners can rely on you for top security – Ecotherm 50 windows are PAS 24 accredited and Document Q compliant and come with high-security multi-point locking and an interlocking bead.
