This is a very common question that gets asked: should I invest in a glass hour or a polycarbonate greenhouse, which is best?
The answer is it depends on your needs, budget, style and long-term vision.
Both materials have their own unique advantages and disadvantages, and understanding the differences between them is essential for making an informed decision.
In this blog post, we will talk about both of them, advantages and disadvantages to help you understand making the right decisions.
Glass Greenhouse
The glass greenhouse is considered as premium quality because of its build quality, style and durability.
It is important to understand that a glass greenhouse is the most expensive in the range but will last a very long time if maintained well.
Polycarbonate Greenhouse
The polycarbonate greenhouse offers a similar outcome as the glass greenhouse or plastic greenhouse but it’s much cheaper compared to the glass greenhouse.
This can be a perfect choice for those who want a mid-range greenhouse, you can achieve a similar look as a glass house but at a much cheaper price.
Comparing Glass Greenhouse vs Polycarbonate
Durability and Strength
Glass greenhouses are known for their exceptional durability and strength. Glass panels are resistant to scratches, fading, and degradation from UV exposure, making them a long-lasting option for greenhouse construction.
However, glass is also prone to breakage, especially in areas prone to extreme weather conditions or where impacts are likely.
On the other hand, polycarbonate greenhouses are highly durable and virtually unbreakable. Polycarbonate panels are lightweight yet incredibly strong, making them resistant to impacts, hail, and high winds. This durability makes polycarbonate greenhouses an excellent choice for areas with unpredictable weather or where protection against vandalism is a concern.
Insulation and Light Transmission
Glass greenhouses offer excellent light transmission, allowing plants to receive ample sunlight for optimal growth. Additionally, glass provides superior insulation, helping to maintain stable temperatures inside the greenhouse and reducing heating costs during colder months.
However, glass may also create hot spots within the greenhouse, leading to uneven heating and potential damage to sensitive plants.
Polycarbonate greenhouses also provide excellent light transmission, with some types of polycarbonate panels offering even greater light diffusion than glass.
This helps to reduce the risk of hot spots and ensures more uniform light distribution throughout the greenhouse. Additionally, polycarbonate panels offer superior insulation compared to glass, helping to maintain stable temperatures and reduce energy costs.
Cost and Maintenance
Glass greenhouses tend to be more expensive upfront than polycarbonate greenhouses due to the higher cost of materials and installation. However, glass requires minimal maintenance over its lifespan, making it a cost-effective option in the long run.
Routine cleaning is typically the only maintenance required for glass greenhouses, helping to keep them looking clear and ensuring optimal light transmission.
Polycarbonate greenhouses are generally more affordable upfront than glass greenhouses, making them a popular choice for budget-conscious gardeners.
Polycarbonate panels are lightweight and easy to install, reducing installation costs. While polycarbonate panels may require occasional cleaning to remove dirt and debris, they are generally low-maintenance and resistant to damage, making them a cost-effective option for greenhouse construction.

Which is best?
Both glass and polycarbonate greenhouses offer unique advantages and disadvantages, and the best choice for your needs will depend on your specific requirements and budget.
Glass greenhouses are known for their exceptional durability, insulation, and light transmission, making them a popular option for serious gardeners and commercial growers. However, glass greenhouses can be expensive to install and may require additional maintenance to keep them looking clear.
Polycarbonate greenhouses are highly durable, lightweight, and cost-effective, making them an excellent choice for beginner gardeners, hobbyists, and those on a budget. While polycarbonate panels may not offer the same level of insulation as glass, they provide excellent light transmission and require minimal maintenance over their lifespan.
