Plastic Sheds
Modern Plastic Sheds have evolved far beyond the brittle PVC structures of the past. Our collection exclusively features High-Impact Polycarbonate (Palram Canopia) and reinforced polymer constructions. These materials are engineered to be virtually unbreakable, UV-stabilized (so they won't turn yellow or brittle in the sun), and completely maintenance-free. Unlike wood, they will never rot, rust, or require painting, making them the definitive choice for coastal locations or damp corners of the garden where organic materials fail.
Why Buy Plastic Sheds from Greenhouse Stores?
Greenhouse Stores is a specialist UK retailer supplying high-performance garden buildings designed to handle British weather conditions. Our Plastic Shed range features industry-leading models from Palram Canopia, renowned for their durability and practical design. Unlike traditional Wooden Sheds that require annual treatment, these polycarbonate buildings offer a maintenance-free solution for secure garden storage. We support our Palram collection with expert product knowledge, official UK warranties, and dedicated customer service to ensure you receive the correct storage solution for your needs.
Understanding Specifications: Polycarbonate Guide
The primary technical advantage of a plastic shed over a wooden alternative is the material stability. Palram sheds use "SkyLight" polycarbonate roof panels which appear opaque from the outside for security but transmit natural soft light into the shed during the day. Structurally, these buildings use a reinforced aluminium frame which is lightweight yet rigid, preventing the sagging often seen in felt-roofed timber sheds. For smaller items, consider our Garden Storage Boxes which use the same durable materials in a compact format.
Why We Chose This Range
“We stock Palram Canopia plastic sheds for one specific innovation: The 'Skylight' Roof. From the outside, the roof looks solid charcoal grey, keeping your valuables hidden from prying eyes. However, the polycarbonate is engineered to transmit 10% of natural sunlight into the shed. This means you don't need to fumble for a torch in the daytime, solving the 'dark cave' problem common with metal and wooden sheds.”
— Matt, Founder of Greenhouse Stores🔧 Matt's Installation Tip: The "Ballast" Requirement
Plastic sheds are significantly lighter than wood. In a high wind, they can slide or tip if not secured, even with a floor installed.
You must anchor the shed to your hard-standing base. Palram sheds come with specific anchor points in the floor. I recommend using M8 Thunderbolts (for concrete) or heavy-duty screw pegs (for paving) to lock the frame to the ground. Do not rely on the weight of your lawnmower to hold the shed down in a storm.”
Frequently Asked Questions regarding Plastic Sheds
-
Do I need a concrete base for a plastic shed?
Yes, a solid, level foundation is required. Although these sheds include a floor, the structure must sit on a hard surface like concrete, paving slabs, or decking. Placing the shed directly on grass or soil will cause the floor to shift, resulting in door misalignment and potential damage.
-
Do plastic sheds get condensation?
They can, as plastic does not "breathe" like wood. However, our Palram models feature integrated air vents at the front and rear to promote cross-flow ventilation. To minimise condensation, ensure you keep these vents clear and avoid storing wet items inside.
-
Are polycarbonate sheds secure and weather-resistant?
Yes. Palram sheds are highly weather-resistant and UV-stabilised to prevent degradation. The polycarbonate panels are virtually unbreakable and do not shatter. For security, standard models feature a latch that accepts a padlock (not included) to secure the contents against wind and unauthorised access.
-
Will the plastic turn yellow or brittle in the sun?
Not with our brands. We only stock UV-stabilized polycarbonate and HDPE sheds. Cheap PVC sheds from budget retailers often crack after a few years, but Palram sheds are tested to withstand harsh UV exposure without degrading for 10+ years.
-
Are plastic sheds fire retardant?
Yes, Palram Canopia sheds are classified as fire retardant, making them a safe choice for locations with strict fire safety regulations, such as caravan parks and campsites where wooden sheds are often prohibited.
