ALITHERM FLUSH · BROCHURE INSPIRATION
Our Flush selection here uses the Alitherm 400 flush-sash option. A level outer appearance creates a neat finish that works with both contemporary architecture and simple cottage styling. This is distinct from the older Alitherm 800 flush-casement system; your quotation will name the exact system supplied.

View the window from outside as well as inside. A flush external sash gives a level appearance, while glazing bars, colour and pane proportions decide whether the overall effect feels contemporary or traditional. Compare a plain two-pane design with the cottage-bar option before selecting your finish.
Overall dimensions, the number of opening lights, glazing specification, decorative bars and colour combinations all affect the quotation. Installation access, the condition of the opening and the extent of making good also need to be checked.
Use our estimate to compare design preferences. Send the selected design with photographs and the number of windows required for a more useful first discussion.
