If you're building a greenhouse or planning a seasonal upgrade, one of the first decisions you'll face is what type of greenhouse covering to use. Two popular options are SolaWrap, a high-end, long-lasting greenhouse film, and 6 mil plastic sheeting, a widely available and budget-friendly alternative.
In this FAQ blog, we answer the most common questions about both products, so you can make an informed decision for your growing needs—whether you're a backyard gardener or running a commercial operation.
SolaWrap is a durable, UV-resistant, and insulated greenhouse film made from UV-stabilized polyethylene with built-in air bubbles (similar to bubble wrap). It’s designed to last 10+ years, offering unmatched light diffusion and insulation.
SolaWrap’s price reflects its durability, insulation, and performance:
Lasts over a decade (vs 1–4 years for standard plastic)
Withstands snow, wind, and hail
Built-in thermal insulation reduces heating costs
88% light transmission and 83% light diffusion = ideal growing conditions
It’s an investment that pays off in reduced energy bills and fewer replacements.
Absolutely. SolaWrap is engineered to perform in:
Harsh winters with heavy snow loads
Hot, UV-intense summers
High-wind environments
Its rounded shape allows snow to slide off, and its triple-wall design insulates against extreme temperatures.
It’s still DIY-friendly with the instructions. You’ll use heavy duty extrusions to slide the film into the track to secure the panels in place, ensuring a tight, wind-resistant seal.
If you’re serious about year-round growing or live in a tough climate, yes. SolaWrap helps:
Extend growing seasons
Protect delicate plants
Lower heating costs
For hobbyists looking for long-term value, it’s a smart, sustainable choice.
6 mil plastic sheeting is a single-layer polyethylene film commonly used for:
Seasonal or temporary greenhouses
Low tunnels and hoop houses
DIY cold frames
It’s lightweight, affordable, and available in clear, white, or UV-treated options.
Standard 6 mil plastic (non-UV treated) may last only 6–12 months. UV-treated versions can last up to 4 years, depending on exposure and conditions.
Not all 6 mil plastic is UV-resistant—check the label or product description. Without UV stabilization, sunlight will degrade it quickly. All versions are waterproof, making them useful for:
Covering plants from rain
Sealing off sections of a greenhouse
Yes. Many growers create an air gap between two layers using a small blower fan, which adds insulation. While it helps, it still won’t match the thermal performance of SolaWrap.
6 mil polyethylene is technically recyclable, but most municipal systems don’t accept it. It also breaks down over time into microplastics if not properly disposed of.
If sustainability is a top concern, SolaWrap’s longevity makes it the greener choice, even though it’s also made from polyethylene.
It’s ideal if you need:
A budget-friendly option
A short-term growing solution
A way to experiment with greenhouse gardening before committing to a permanent structure
