Strength and security
Because these products are produced from extruded aluminium, a material considerably stronger than plastic (PVCu), the frames and panels are completely rigid to prevent warping, twisting or sticking and making them resistant to attack and virtually intruder proof.

Choice of finish
New Generation Aluminium is available in a wide range of colour finishes (Any RAL Colour) or authentic wood grain foils should the situation demand.

Maintain the attraction with ease
Unlike other materials, aluminium neither absorbs water, rots or rusts. Also aluminium windows and doors do not attract dirt or discolour, making them virtually maintenance free apart from the occasional wipe down with a damp cloth.


Slimline looks with security in mind
The slim line elegance of these windows and doors offer distinctive styles for both modern and traditional projects, and all offer the latest in-built security. The energy efficient Low E double-glazed sealed units are fixed in place using high security glazing beads with the addition of optional security glazing clips making them extremely difficult to de-glaze. Our window vents use the highly regarded Saracen mechanism.

Our 'New Generation Aluminium' Products includes a full range of replacement windows, entrance and patio doors, porches and conservatories, all of which offer the discerning customer a stunning slim line and robust alternative to PVCu.

Secondary Glazing Systems
Aluminium secondary glazing systems are also available for use where it is not possible to remove and replace existing windows, for example conservation areas or where buildings are listed etc.

Zellers aluminium windows, doors and conservatory systems can be installed efficiently and at competitive prices.
