The practicality and style of each of these windows differs so we are on hand to take you through the various options and possibilities to ensure that you choose the perfect windows for your property.

A key choice to consider when looking at the design of your Genesis windows is that of joint types for the sashes and the outer frame. Many manufacturers still use outdated and unsightly standard welded joints which produce a 4mm to 5mm diagonal join which generally spoils the appearance of the window.

With Genesis your can be assured this won’t be a problem as you can choose from either the Graf weld or a fully mechanically manufactured window. The Graf weld technology produces corners that have a hairline join which is barely visible and gives an incredibly neat finish. When used in conjunction with a grained woodgrain foil the graf welded corners look particularly effective and the join cannot be seen from a couple of metres away. The other alternative construction method is to fully mechanically manufacture the frames and the sashes. Fully mechanically jointing the windows in this way is the most realistic and authentic finish that many property and homeowners choose due to the close resemblance to the manufacture of timber equivalents. The mechanical jointed option is particularly popular with owners period homes as they have had a number of successes in conservation areas, listed buildings and other regions requiring planning consent

Another customisable feature available with our Aluminium windows and PVC windows is the colour of the windows themselves and the colour of the hardware. One outstanding facility available with a Genesis window is the colour matching service. If you already have windows or other furnishings in a colour you like we can use our ‘colour matching service’ to help you replicate the colour and style you love.
