VELFAC windows – in detail

Low maintenance design

Proven to withstand the most extreme weather conditions, the external aluminium frame also never needs repainting for the lifetime of the installation.

Thermal performance

VELFAC windows offer U-values as low as 0.8W/m2K for triple glazed units. The slim frame contributes to excellent thermal (and acoustic) insulation as glass is a better insulator than the frame.

Sustainability

Sustainability is fundamental to the VELFAC design philosophy. All materials used are responsibly sourced, wood treatments are water-based, and every window unit is 93% re-usable.

Security

VELFAC 200 windows are Secured by Design approved and offer a range of security features including internal glazing beads (to prevent the external removal of glass panes), and multi-point locking systems. The external aluminium frame is also highly resistant to forced entry.

Glass options and accessories

VELFAC offers a range of glazing options to customise window performance, including a selection of opaque designs for added privacy and security. VELFAC-designed handles, hinges, restrictors and other accessories are also available.

Frame finishes

The standard VELFAC frame features polyester-powder coated external aluminium and painted or lacquered internal timber. The frame can be finished in different colours inside and out in any of the full range of RAL colours, or in a granite or anodised coating (aluminium only).

Warranties

VELFAC offers a 12 year comprehensive product warranty on all windows, and five years on all casement, sliding, and external doors.

Composite frame

The signature VELFAC frame combines durable external aluminium with natural, welcoming internal timber. By placing the moving aluminium sash directly in front of the fixed timber frame the window delivers a ‘floating sash’ effect, further emphasised by the recessed weather seal. The slim frame maximises natural light while uniform sightlines deliver an identical external appearance for every window unit, irrespective of opening function, manual or motorised operation, or whether double or triple glazed.
