Which Glazing System is Right for you?
BC Greenhouse Builders is pleased to offer many different glazing systems to personalize your greenhouse to your exact needs and preferences.


Single Pane Glass:
Single glazing is one of the most economical glazing systems and makes for a nice show piece in your yard. All our single glass is tempered safety glass to minimize any possibility of breakage or injury. The traditional look appeals to greenhouse gardens with full light transmission capable of controlling their growing variable. Single pane glass is adequate for keeping a `cool greenhouse` in mild climates.

R value = 0.9.
Approximately 95% light transmission.


Double Pane Glass:
Double glaze insulated glass offers the gardener a spectacular view of plants and flowers while maintaining a superb heat insulation for all types of growing. All our double glazed glass is tempered safety glass to minimize any possibility of breakage or injury. Insulated double glass is the best of both worlds, providing you with the aesthetically pleasing look of glass and the insulation you may require for your specialty plants.

Approximately 90% light transmission

Double glaze glass can also be upgraded to a high-performance Low E glass to help keep the greenhouse even cooler in the summer and warmer in the winter while still maintaining the light necessary for plant growth. Other high performance options are available, please contact us for more information.

Twinwall Polycarbonate:
Our 6mm twinwall polycarbonate is the most economical glazing materials. It is a practical for a `growing greenhouse` as it offers 50% more insulation than single pane glass and diffuses harmful sunlight in the summer. It is essentially unbreakable, making it very safe in a family environment. The insulation will prevent the temperature in the greenhouse from changing drastically and results in the best possible growing environment.

R value = 1.59.
Approximately 82% light transmission.


Fivewall Polycarbonate:
We are pleased to introduce the most energy efficient covering available on standard greenhouses today. Our new 16mm fivewall polycarbonate offers unbeatable insulation which is 50% more insulating than double pane glass, or 80% more efficient than 6mm or 8mm twinwall polycarbonate. Fivewall is ideal for colder climates, gardeners who grow specialty plants, or for those who prefer the most energy efficient greenhouse to reduce heating costs.

R value = 3.03.
