Constructed with elegance and durability in mind, the premium 8′ x 20′ Palram Canopia Glory Grey Polygreenhouse (2.4m x 6m) is extremely sturdy and provides optimal conditions for plant growth. Made from high-quality 10mm twin-wall polycarbonate sheets that are impact-resistant, this 8×20 greenhouse features a robust powder-coated aluminum frame and a reinforced structure that is rust-resistant. With a wind resistance rating of up to 100km/ hr (62ml/ hr) and snow-load tested up to 100kg/ m² (20.5lbs/ ft²), it offers superior protection against harsh weather conditions.

The twin wall polycarbonate panels allow 79% light transmission, are UV-protected, and help regulate temperature by improving thermal insulation while reducing intense sunlight exposure. This ensures that plants thrive in ideal conditions, while providing a safe environment for gardeners with UV-ray protection and long-lasting panels that do not discolor under the sun. The traditional apex roof design aids in effective rainwater drainage.

Access is provided through a single door that can be installed for either left or right-hand opening, equipped with a low threshold, bottom seal, and key-operated lock to keep tools secure. Inside, the generous height allows for ample headroom and storage space for taller items. Integrated rain gutters offer a sustainable water supply for plants, while a side louvre window and 4 roof vents help regulate temperature for plants and gardeners.

Backed by a solid 10-year limited warranty and requiring minimal maintenance, this greenhouse’s pre-cut high-impact polycarbonate panels with consistent profiles ensure easy assembly. As it does not include a floor, it should be installed on a solid, level surface. Available in various sizes, an optional portable fan greenhouse heater with digital thermostat can be purchased for added convenience.

Delivery is free to most UK locations. The greenhouse comes with a 10-year limited warranty, a rust-resistant powder-coated aluminum frame, a reinforced structure, and many other features to ensure optimal growing conditions for plants while offering ease of maintenance.

FAQs

The size of the shed depends on what you plan to store or use it for. Measure the items you plan to store and consider any additional space for moving around or future storage needs. Common sizes range from small (6×8 feet) for basic storage to large (12×24 feet) for workshops or extensive storage.
Sheds are typically made from wood, metal, or plastic. Wood is aesthetically pleasing and customizable but requires more maintenance. Metal sheds are durable and secure but can be prone to rust. Plastic sheds are low-maintenance and easy to assemble but may not be as sturdy as wood or metal.

Permit requirements vary by location. Check with your local building department or zoning office. Typically, small sheds (under 120 square feet) may not require a permit, but larger ones or those with electrical installations often do.

A solid foundation is crucial for stability and longevity. Options include concrete slabs, gravel bases, or wooden platforms. Choose a foundation based on your shed’s size, material, and the ground conditions of your site.
Look for sheds with features like weather-resistant materials, proper sealing, and robust construction. Ensure the shed has a good roof overhang, proper drainage, and secure locking mechanisms to protect against theft and weather damage.
Assembly time depends on the size and complexity of the shed. Small, simple sheds can be assembled in a few hours, while larger or more complex sheds may take a full day or more. Professional installation is also an option for those who prefer not to DIY.
Maintenance depends on the material. Wooden sheds need periodic painting or staining and checking for rot or pests. Metal sheds may need rust prevention treatments. Plastic sheds require minimal maintenance, typically just cleaning as needed.
Moving a shed is possible but can be challenging, especially for larger structures. It’s easier to move a smaller shed if it has a solid base. Consider the logistics and potential costs of moving before installation. If moving is likely, a portable shed might be a better option.
Many sheds come with detailed assembly instructions, making them suitable for DIY installation, especially smaller models. However, larger or more complex sheds may require professional installation to ensure they are properly and safely assembled. Assess your skill level, available tools, and the complexity of the shed before deciding.
