VELFAC 200 is the composite window most often specified in the UK: a powder-coated aluminium outer frame shields a finished timber inner frame from the weather.
Why composite construction persists
The aluminium outer face removes almost all of the external maintenance associated with timber joinery, while the internal timber face keeps the tactile quality traditional windows are prized for.
Thermal figures
A Uw from 0.8 W/m²K is genuinely strong for a residential window and compares favourably with some flagship all-aluminium systems, including the Schüco AWS 90 SI+.
Where it earns its place
VELFAC 200 is a natural fit for refurbishments of period houses in Letchworth Garden City where the brief calls for a warm interior finish and a low-maintenance external face.
For readers researching options locally, 5EC's aluminium windows and 5EC's heritage aluminium range are both worth reviewing — both are handled by 5EC, a Stevenage-based authorised supplier working across Hertfordshire.
