There are two main ways to secure a window or screen in place and this will depend on the sizing of the glass/perspex. If the glass/perspex is bigger than the hole in the body then a ‘S’ section rubber will be required. If the glass/perspex is smaller than the hole in the body then a Claytonrite rubber will be required.
A Claytonrite screen or window seal has a locking strip inserted into the rubber to lock it all in place. To decide which is the most suitable profile for your application you will need three important measurements, glass thickness, panel thickness and the clearance or web gap. It is advisable to take your measurements from the actual glass and panel rather than from the old rubber as rubber shrinks with age and you may not receive a true measurement. The clearance or web gap is very important because if the rubber is too big you will have difficulty in putting in your screen or window and could crack or break it. If the gap is to too small a strip of N S P Cord can be placed in one of the channels to pack out the size of the gap. Please click the link below to see a diagram explaining this.
