A range of performance timber & aluminium clad windows with double or triple glazed options
Energy PlusA range of quality performance timber windows made from engineered northern European redwood. Our Energy Plus range includes flush casement, lipped casement, sliding sash and tilt and turn, top hung and top sliding windows, all available in  over 200+ RAL colours, factory finished with breathable micropore paint.

Energy Plus windows provide the perfect solution for self-build, restoration projects and new  installations alike. The modern glass and glazing provide excellent performance whilst strong slim timber sits beautifully in conservation areas or sensitive property developments. 

The  units use tough and warp resistant timber that gives the windows a strong back bone to support the performance glazing. We use low U-Value glass argon filled sealed units, with all joints sealed with warm edge space bar separating the glazing;  stopping draughts  ensuring heat transfer across the double glazing is minimal.
