Greenhouses of all sizes are commonly found in backyards and also on large mass-production farms. Greenhouses make it easier for gardeners to grow flowers and vegetables year-round without the worry of sudden drops in temperature, frost of other natural forces that would otherwise kill your plants. Insulating a greenhouse to help maintain a steady inside temperature is both easy and effective with the right materials.
Measure the walls and ceiling of the greenhouse to determine how much bubble wrap will be needed to completely insulate the greenhouse.
Cut the bubble wrap to the appropriate size. Use a utility knife to make a clean, even cuts in the bubble wrap.
Attach the bubble wrap to the walls and ceiling using a staple gun, if the frame of the greenhouse if constructed of wood. If the frame of the greenhouse is made of a form of metal, use adhesive velcro strips to secure the bubble wrap to the walls and ceiling of the greenhouse.
Cut out areas in the bubble wrap for windows and venting systems, and ensure that you secure the bubble wrap around the outline of the window or venting system to provide the best possible insulation.
