Before buying any bubble wrap, measure the sides, roof and ends of the greenhouse.
Starting with the sides, fix the bubble wrap to the frame using nails, drawing pins or wire, keeping it tight for extra insulation.
When insulating the roof, fix the bubble wrap to the ridge and spread it down the glazing bars.
Cut and fasten the bubble wrap around windows, vents and louvres so they can be opened.
