Greenhouse Twinwall Bubble Insulation (4.5′ x 25′ Roll)

Measurements: 4 1/2′ W x 25′ L roll (112 square feet)
This unique twinwall bubble insulation can drastically reduce your greenhouse heating costs by as much as 45%. In addition to saving you money during the cool seasons, it will also help prevent overheating during the hot summer months. This unique bubble is only 3/16″ thick but provides 15% more insulation than other bubble over twice as thick because of the extra outer layer that traps more air inside. Twinwall bubble insulation also has clear bubbles for better light transmission, and a reinforced backing for longer life. Works well with all types of greenhouse coverings. Shown installed with bubble clips. For best results, tape sections together with the greenhouse poly patching tape (4″ or wider is recommended). Bubble should be installed on the inside of the greenhouse.
