For growers, hobbyists, and commercial farmers alike, selecting the right greenhouse covering is a crucial decision. It influences not only plant health and yield but also your long-term costs, maintenance needs, and energy efficiency. While many opt for standard 6 mil polyethylene (poly) plastic, a premium alternative known as SolaWrap greenhouse film is changing the game. But is it worth the investment?
This blog will explore the key differences between SolaWrap and standard greenhouse plastic, covering areas such as lifespan, insulation, light transmission, durability, and overall value. Whether you’re just building your first greenhouse or thinking about upgrading, this guide will help you make an informed decision.
1. What Is Standard Greenhouse Plastic?
Standard greenhouse plastic is typically a single- or double-layer polyethylene film ranging from 4 to 6 mils in thickness. It’s widely used due to its low cost and ease of installation. Most standard plastic films are treated for UV resistance and may be designed to last 1 to 4 seasons, depending on quality and climate conditions.
Pros of Standard Greenhouse Plastic:
-
Low initial cost
-
Easy to install and replace
-
Lightweight
-
Readily available at big-box stores and online retailers
Cons:
-
Limited lifespan
-
Can degrade quickly in harsh sun or wind
-
Poor insulation compared to premium alternatives
-
Requires frequent replacement and contributes to plastic waste
2. What Is SolaWrap Greenhouse Film?
SolaWrap is a high-performance greenhouse covering made from multiple layers of polyethylene encapsulating a bubble-cell layer, which provides superior insulation and structure. Originally developed in Europe, SolaWrap has been engineered to withstand extreme weather and deliver decades of consistent performance.
Key Features of SolaWrap:
-
Bubble-cell structure for insulation
-
Light diffusion rate of 83% for even light distribution
-
10+ year lifespan (UV-stabilized)
-
Wind rating up to 100 mph
-
Snow load rating of 120 lbs per square foot
-
Can be attached with a track-and-keder system for expansion/contraction
3. Lifespan & Durability
SolaWrap wins hands-down when it comes to longevity. Standard greenhouse plastic typically needs replacement every 1-3 years, especially in sunny, windy, or snowy climates. In contrast, SolaWrap is known to last 10 years or more, with many users reporting successful use beyond 15 years.
Durability Factors to Consider:
-
UV resistance: SolaWrap’s multi-layer structure resists UV degradation significantly longer.
-
Puncture & tear resistance: The bubble-cell design prevents small tears from spreading.
-
Weather resilience: SolaWrap is engineered to withstand heavy winds, hail, and snow—conditions that quickly damage standard poly.
4. Insulation and Energy Efficiency
Standard polyethylene film provides minimal insulation, which can make greenhouses more vulnerable to outside temperature fluctuations. That means more heating in winter and cooling in summer—both of which raise energy bills.
SolaWrap’s built-in air pockets in the bubble structure act like double- or triple-pane windows, offering exceptional thermal insulation. This keeps internal temperatures more stable and reduces the cost of climate control.
Estimated Energy Savings: Growers using SolaWrap have reported energy savings of up to 40-50% compared to traditional poly-covered structures.
5. Light Transmission & Plant Growth
When it comes to growing plants, light matters—but not just how much light, but how that light is distributed.
Standard plastic films tend to allow direct sunlight, which can create hotspots and inconsistent lighting across the growing space. This can stress plants and create uneven growth.
SolaWrap is designed for 83% light transmission with full diffusion, meaning sunlight is spread evenly throughout the greenhouse. This leads to:
-
More uniform crop growth
-
Reduced leaf burn
-
Improved plant health and yields
6. Installation and Maintenance
Standard poly films are typically secured with clips, lath, or staples. They can flap in high winds and often need repairs or tightening.
SolaWrap uses a keder and track system, which allows for:
-
Easy thermal expansion and contraction
-
Stronger sealing and wind protection
-
Clean and professional installation
Maintenance is also minimal due to SolaWrap’s resistance to tearing, UV damage, and temperature extremes.
7. Sustainability and Waste Reduction
If sustainability is part of your growing philosophy, SolaWrap’s long lifespan means less plastic waste over time. Instead of discarding plastic every 4 years, you can keep your covering in place for a decade or more.
8. When Should You Choose SolaWrap?
While standard poly may be fine for temporary greenhouses or tight budgets, SolaWrap is the better choice for:
-
Commercial growers seeking reliability and energy savings
-
Year-round growing in cold or variable climates
-
Growers focused on sustainability and long-term performance
-
Anyone tired of replacing plastic every 4 years unless it's damaged due to hail, snow, etc
Final Thoughts
Is SolaWrap worth it? For many growers, the answer is yes.
Though the upfront cost is higher, the durability, insulation, energy savings, and light diffusion make SolaWrap an investment that pays off year after year. Whether you’re a seasoned farmer or a home gardener looking for lasting results, SolaWrap offers unmatched value in the greenhouse market.
