Greenhouse Glazing: What to Choose?

Glazing is the material that covers the greenhouse frame. The best commonly used choices are glass, plexiglass, polycarbonate and poly film.
Greenhouse glazing choice usually dictates the design, along with the price, of the greenhouse. When you consider glazing options, take into account suitability for your site, the necessary installation skill level and also your budget.
Now let’s consider 3 best choices for your greenhouse.
Glass and plexiglass
Glass and plexiglass are long-lived, strong greenhouse glazing options. Due to these materials’ rigidity, installing of either makes it necessary that you be skilled and precise. Glass is heavy and brittle. Plexiglass is a lot easier to use, but scratches and is used by just a few manufacturers.
Neither of those transparent materials diffuses light well, that is a lot less than optimal for the growing plants. Both glass and plexiglass might be expensive to repair if you reside inside an area with periodic hailstorms. Prices of those materials are moderate to high.
Polycarbonate
Polycarbonate is actually a rigid, translucent plastic obtainable in single layer and honeycomb styles, much like corrugated cardboard.
This material could be cut by using a saw and is also much easier to install than glass or plexiglass. Longevity varies, but polycarbonate is frequently warranted for 10 years. Single layer “polycarb” prices are within the mid ranges, although the more power efficient honeycomb is often pricey.
Poly film
Poly film is a thick, flexible material which is easy to install with homeowner tools and modest building skills. Its translucency diffuses light well, bouncing the accessible sunlight and reducing shadows, which aid plant growth.
Determined by your own gardening conditions, poly film lasts 6 – 8 years for the majority of growers. (Longer for many people, we’ve discovered.) It can be easily replaced when needed and is the most affordable glazing choice.
This pliable material is a great match for the greenhouses with rounded shape.
Greenhouse poly film with ultraviolet (UV) protection is our preferred glazing material for quick and easy installation, versatility and low price. Custom sized, 6-mil film, that has a 4 year guarantee is included as part of your greenhouse kit, together with complete assembly instructions.
