Aluminium Windows

Ecotherm Finesse

Super slim steel look profile designed as a thermally broken replacement for old steel windows. Ecotherm Finesse incorporates slim sightlines and has the appearance inspired by the traditional old steel windows. It is ideal for listed buildings and replica refurbishment projects where planning constraints need to be considered.


A lifetime of elegance. Ecotherm windows and doors have been designed to bring a touch of luxury to your life.

Secondary glazing

Secondary glazing is ideal if you wish to keep the external appearance of your windows, but increase the thermal efficiency of the room. It can be designed to match the layout of the existing window so as not to look out of place.

Secondary glazing is perfect for use in Listed Buildings and conservation areas. Made from strong light weight aluminium, it can be made to be very slim and discreet. Considered a reversible change, secondary glazing is recommended by English Heritage and the Listed Property Owners Club.
