What Is Better Glass Or Polycarbonate Greenhouse


When it comes to choosing the right greenhouse for your garden, the decision often comes down to two popular options: glass and polycarbonate. Both have their advantages and drawbacks, making the choice a bit tricky. In this blog post, we’ll explore the benefits and downsides of glass and polycarbonate greenhouse option to help you make an informed decision. Let’s dive in!

Transparency and Light Transmission

Glass: Glass greenhouses are known for their excellent light transmission. They allow natural sunlight to penetrate with minimal distortion, which is essential for the healthy growth of plants. This can create a beautiful and bright space for your garden.

Polycarbonate: Polycarbonate greenhouses are also transparent but can scatter light to some extent. However, modern polycarbonate materials have improved light diffusion, ensuring your plants receive ample sunlight without hot spots.

Insulation and Temperature Control

Glass: Glass greenhouses tend to provide better insulation, maintaining a more stable temperature inside. This can be beneficial in extreme weather conditions, as it reduces the need for additional heating or cooling.

Polycarbonate: Polycarbonate greenhouses offer reasonable insulation, but they might require additional ventilation and shading in very hot climates to prevent overheating.

Durability and Longevity

Glass: Glass is fragile and prone to breakage. However, tempered or safety glass is available, which is more resilient and shatter-resistant. Regular glass greenhouses may need more maintenance over time.

Polycarbonate: Polycarbonate is known for its durability. It can withstand impacts, extreme weather conditions, and is less likely to break or shatter. This makes polycarbonate greenhouse a long-lasting option with minimal maintenance requirements.

Weight and Installation

Glass: Glass is heavier and more challenging to install. It may require a sturdier frame and more professional assistance during construction.

Polycarbonate: Polycarbonate is lightweight, making it easier to handle and install. It doesn’t demand an exceptionally strong structure, which can reduce installation costs.

Cost Considerations

Glass: Glass greenhouses are typically more expensive upfront due to the cost of materials and installation. However, their longevity can make them a worthwhile investment over time.

Polycarbonate: Polycarbonate greenhouses are generally more budget-friendly. While you may have lower initial costs, they might require replacements or maintenance sooner than glass greenhouses.


Glass: Glass greenhouses are relatively low-maintenance in terms of cleaning. However, you should be prepared for potential glass replacements in case of breakage.

Polycarbonate: Polycarbonate greenhouses are easy to maintain. They require occasional cleaning and are less prone to damage, reducing long-term maintenance costs.

Customisation and Design

Glass: Glass greenhouses have a classic, timeless look that many gardeners appreciate. They can enhance the overall aesthetics of your garden.

Polycarbonate: Polycarbonate glasshouses are available in a variety of styles that may be tailored to match the aesthetic of your garden. While they may not have the traditional appeal of glass, they offer versatility in design.

So, which is better: glass or polycarbonate greenhouse? The answer depends on your specific needs and priorities. Glass provides superior light transmission and insulation, making it ideal for serious gardeners willing to invest more upfront. On the other hand, polycarbonate is durable, cost-effective, and easier to install.

Consider your climate, budget, and long-term goals for your greenhouse when making the choice. Whichever you choose, both glass and polycarbonate greenhouse can provide an ideal environment for your plants to thrive and your gardening dreams to flourish.
