The mechanical version of Genesis Flush is manufactured using traditional jointing methods to give a truly authentic alternative to expensive, high-maintenance timber windows.

Stunning traditional timber looks are only half the story. Genesis Flush has been meticulously engineered using modern materials and techniques to provide class-leading performance.

Add to that enhanced PAS 24 security, the option for double or triple glazing, and a wide range of hardware options

Our Genesis colour collection has been specially designed to help you put together the perfect colour palette for your home. Available in a wide range of colours and woodgrains, you can choose to have the same finish on the inside and outside of the window, or use colour and woodgrain on the outside, with our Smooth or Heritage white finish on the inside. The choice is yours.

When it comes to conservation areas, windows are a key feature that can change the appearance of a property. Genesis Flush has been carefully designed with this in mind. Its flush external face, simple contours, timber-style mechanical or seamless joints and heritage woodgrains and colours all add up to a truly authentic window that meets the requirements of many conservation areas and officers across the country.

Genesis and conservation … a perfect match.
