Glazing your greenhouse will save you about 30 per cent on energy costs, while protecting the plants inside the greenhouse from UV rays. Glaze comes in the form of flexible polythene panels or the more rigid polycarbonate panels, which are better for greenhouses requiring thicker panels. These panels slip into special channels that are attached to the frame of your greenhouse.
Erect a greenhouse frame that comes with attached glazing bar channels.
Put dishwashing soap into the glazing bar channels. This will allow the rubber glazing strips to slide in easier.
Slide the rubber glazing strips into the glazing bar channels. This will protect the panels.
