Rigid Coverings & Polycarbonate

Gothic Arch Greenhouses offers replacement rigid greenhouse glazing pieces in a variety of thicknesses and insulation values to suit any application.

Multi-wall Polycarbonate

Our polycarbonate is the most economical glazing material available. Very practical for a 'growing greenhouse', our twin-wall polycarbonate offers 50% more insulation than single-pane glass and diffuses sunlight which may become too strong in the summer. It is essentially unbreakable, making it very safe in a family environment. The amount of insulation that twin-wall provides will prevent the temperature in the greenhouse from changing drastically, which results in the best possible growing environment for your backyard garden.

We also offer triple-wall and five-wall polycarbonate in several thicknesses to offer the perfect amount of energy savings and have clear, bronze, and opal tints to control the amount of sunlight that enters. These provide up to 80% more insulation value over clear 6mm polycarbonates and are able to resist high winds, hail, and heavier snow loads. Five-wall greenhouse covering is ideal for colder climates, for gardeners who grow specialty plants, or for those who prefer the most energy-efficient greenhouse to reduce heating costs.

This glazing is the perfect, lightweight alternative to traditional glass glazing. In addition to being used as greenhouse glazing, it is also ideal for a wide variety of applications, including industrial roofing, office partitions, pool enclosures, patio coverings, skylights, and sunrooms. Our polycarbonates are available in clear, opal, or bronze finishes, come standard in 4’ or 6’ sizes, and are covered by a 10-year limited warranty.

Our acrylic greenhouse panels provide an excellent cover where the grower is in control and don’t have to react to changing conditions. Because these panels are resistant to yellowing, there is no need to change growing techniques to offset declining light levels. Acrylic panels have up to a 30-year life expectancy and come with a full 10-year warranty.

R-value 1.82, up to 90% light transmission


Our fiberglass roll is a flexible, economical greenhouse covering that provides excellent light transmission, withstands heavy snow and wind, and is resistant to breaking, hazing, and sagging.

R value = 1.5, approximately 70% light transmission

Corrugated Polycarbonate

Gothic Arch Greenhouses carries DynaGlas corrugated glazing systems. Dynaglas offers the same sparkling clarity as glass, but because it requires no shade-casting glazing system, DynaGlas transmits as much as 7% more light. DynaGlas Plus SolarSoft 85™ offers high light transmission (85%), but also offers 100% light diffusion, helping to spread light throughout the greenhouse and reduce shadows.

R-value = 0.83, up to 92% light transmission
