There are several options when it comes to greenhouse coverings. Between glass, plastic, and fabric coverings, it can be difficult to decide which material is best suited to your unique growing project. Though there are pros and cons to each material, woven greenhouse fabric is the way to go for most operations. It’s also the choice most widely used by serious growers. Here’s why.
Here Are the Benefits of Using Woven Greenhouse Fabric:
Though glass coverings provide a certain aesthetic appeal, they aren’t necessarily the most practical choice. Glass breaks easily and is expensive to maintain. Poor weather conditions such as hail or falling tree branches can permanently damage glass (and any plants protected beneath it). Cracked panels must regularly be replaced making start-up costs, and maintenance costs higher than any other greenhouse cover. Polyethylene covers, on the other hand, are inherently flexible. They can withstand changing weather conditions and can cover almost any greenhouse shape or size. They stand up to wear and tear easily and do not require replacement regularly.
It’s More Durable
In the same vein, polyethylene covers are more durable than glass, fiberglass, acrylic, or polycarbonate coverings. Just as more flexible metals are more durable than rigid metals, flexible greenhouse covers are more durable than their rigid counterparts. BTL-12 is one of the strongest woven greenhouse covers on the market using thick, reinforced polyethylene that is weather resistant, light damage resistant, and under warranty for up to five years. They can be cleaned easily using only a hose and will not break or tear under duress.
It’s More Light Efficient
Woven greenhouse fabrics allow 80%-87% UV transfer—meaning plants receive the maximum amount of sunlight needed to grow while diffusing excess UV light. Not to mention, there is more growing space available under polyethylene cover. This is because traditional glass, fiberglass, or polycarbonate covers install over large structural ramparts. These structural elements shade parts of the garden plot—and not others—leading to light filtration inconsistencies. BTL-12, however, provides a clear covering that delivers direct sunlight with minimal obstructions.
It’s All Seasonal
Greenhouses built for aesthetic purposes have one major drawback—they are often too hot during the summer months, and not hot enough during the winter months. For this reason, woven polyethylene covers provide the ideal greenhouse cover for use all year long. Light diffuses through the fabric allowing the perfect amount of sunlight to penetrate the plants and soil in the summer. Because woven greenhouse covers retain heat more efficiently, they are also the warmer option for the long, cold winter months. Finally, woven greenhouses covers are ideal for growers who use light dep methods to mimic nature’s growing seasons. Simply fit blackout tarps over the greenhouse to control light cycles based on your growing needs.
It’s More Economical
Polyethylene is also the more economical alternative—and it is for this reason that woven greenhouse covers are the most popular greenhouse option. It is less expensive to install—the average greenhouse glass is $2.50/square foot while BTL-12 is only $0.25/square foot. It is also more heat efficient over the long-term. Polyethylene covers have been found to reduce heating costs by 40% compared to glass, fiberglass, or polycarbonate covers. This is because they reflect infrared light back into the greenhouse helping it to retain humidity and heat throughout the season. Finally, polyethylene covers can fit greenhouses of any size or shape making them ideal for space-saving economical urban gardens.
For these reasons, most serious growers choose to use woven greenhouse fabric instead of glass, fiberglass, or polycarbonate covers. They are more flexible, durable, light-efficient, seasonal, and economical than their more rigid counterparts. BTL Liners makes BTL-12, 12-mil woven greenhouse material that is one of the strongest covers on the market—and the most economical.
