Greenhouse Glazing Systems
We offer many options including single tempered glass, tempered insulated double glass, twinwall polycarbonate, and fivewall polycarbonate. For those customers wanting a living and growing space, we also offer tinted, high performance and laminated glass. We can help you choose the best balance between insulating value, aesthetics, and budget to suit your needs.
Things you should know:
- Our continuous, exterior capping system secures the glazing and maintains an airtight seal – there are no gaps or clips. This greenhouse is designed to be weather resistant and energy efficient.
- All glazing options can be intermixed in the same greenhouse
- Our 3mm single tempered glass is offered with a 1/2″ overlap which is easier to ship and install. A 6mm one piece of single tempered glass is an upgraded option for those that would prefer a clean look.

Which Greenhouse Glazing System is Right for you?
Single Glass:
Single glass makes for a nice show piece in your yard. Our single glass is tempered safety glass to minimize any possibility of breakage or injury. Glass appeals to gardeners who want full light transmission to control the amount of sun in the greenhouse.
Single Glass 3MM, Insulating R-Value .96 Approximately 95% light transmission.
Double Glass:
Insulated double glass maintains superb heat insulation for all types of growing. Our double glass is tempered safety glass to minimize any possibility of breakage or injury.
Double Glass 16MM, Insulating R Value 2.1 Approximately 90% light transmission
Optional high performance Low E glass (R Value) Heat Gain = 3.45. Approximately 70% light transmission
Twinwall Polycarbonate:
Our 6mm twinwall polycarbonate is the most economical. It is a practical choice for a working 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.
Twin Wall 6MM, Insulating R-Value 1.62. Approximately 82% light transmission.
Fivewall Polycarbonate:
Our 16mm fivewall polycarbonate is the most energy efficient glazing available on the market today. It offers 50% more insulation than double glass and 80% more insulation than twinwall polycarbonate. Fivewall is ideal for colder climates and gardeners who grow specialty plants, or for those who wish to reduce long term heating costs.
Fivewall 16MM, Insulating R Value 3.0. Approximately 62% light transmission.
Upgraded Glazing Options:
6MM Full Sheet Glass: One solid sheet of tempered safety glass
in every greenhouse bay which is double the thickness for even more strength and a
beautiful seamless look.
6MM Laminated Glass: One solid sheet of laminated safety glass
in every greenhouse bay. Similar to car windshields, this safety glass will not
shatter and will remain intact even when broken. This glass type may be required
for greenhouse roof’s where building codes require, common for applications over
swimming pools, schools, and solariums. Available in single 6MM or Double Glass which is typically composed of an exterior tempered glass piece, an air gap with two layers of float/annealed 3mm glass and a laminated interlayer which blocks UV.
High Performance LOW-E: Maximizes the Insulating R-Value and reduces Relative
Heat Gain to allow for a more comfortable space. The Low-E (low emissivity) coating on the inside of the glass reflects most UV and infrared while keeping a clear view
through the glass. The Low-E coating also reflects infrared back towards the interior retaining more heat.
