How easy it is to assemble Palram – Canopia kits?

Palram – Canopia kits are specifically designed for DIY assembly. Large products can usually be assembled by two handy people. Follow the assembly instructions carefully. Work gloves are strongly recommended when sliding panels. Always wear shoes and safety goggles when working with extruded aluminium.

Can Palram – Canopia products be extended?

Only specific kits are designed to be extended and only using designated Palram – Canopia extension kits. Extendable products are noted as such on our website at the product page’s Overview tab, as well as in the assembly instructions where the “Extendable Product” mark appear on the right bottom corner of the cover.

Can the products be modified?

Our kits are designed as complete products and are not meant to be modified. Making modifications is solely at the customer’s responsibility and will void the warranty.

Is it necessary to prepare a level foundation for grounding products?

The stability and long-term usability of grounded products heavily rely on the preparation of a firm foundation for placement and fixing. Foundation must be level and sized to match the product’s dimensions with room to spare for access and ventilation. The lack of a firm foundation may result in product warping, window or door not closing properly, damaged frame and failing of the product in high winds and extreme weather conditions. The foundation must also be able to drain out the water to prevent stagnation and promotion of algae, insects etc. The surface must ba solid, such as concrete ground/slabs or asphalt. The screws and anchors must be compatible with surface type. A ground cover is highly recommended before installing any kind of foundation. If your site has high moisture content you will need to install a vapor barrier, a 6 mm black plastic.

What is polycarbonate?

Polycarbonates are a group of thermoplastic polymers. Their strength and toughness allows them to be used as either commodity and or engineering plastics. They have superior service temperature range, impact resistance and optical quality. For more information please refer to the “Why Polycarbonate?”

Does Polycarbonate provide or require UV protection?

Polycarbonate inherently absorbs up to 100% of harmful UV radiation; it provides complete protection but in order to maintain its properties and integrity for many years it needs to be protected. Palram – Canopia Polycarbonate panels for exterior use have an embedded UV protective layer that must be installed outwards facing the sun. Twin-wall or multi-wall panels have a “This side out” marking (see attached example); please make sure you install them accordingly and remove the marking after installation.

What advantages do polycarbonate greenhouses have over glass greenhouses?

Polycarbonate panels withstand extreme weather conditions due to their strength and flexibility. They do not shatter consequently they are safer than glass, which is especially important in a domestic environment and the vicinity of children and the elderly. The low weight of the panels – less than 1kg – makes the greenhouse easy to deliver, handle, assemble and also relocate – an assembled 6×8 harmony greenhouse weighs less than 45kg. Polycarbonate complete shields from the harmful effects of UV radiation and protects everything inside the greenhouse: people, plants, pots, tools etc.

What are the major differences between the greenhouses series?

Greenhouse series differ in their glazing types, frame material, size and available accessories. Clear polycarbonate provides maximum light transmission, whereas twin-wall provides high insulation and transmits 70% diffused light that protects from strong sunlight exposure. Hybrid glazing greenhouses have twin-wall roof panels and clear walls, which practically provide light diffusion and a clear view sideways. Aluminium frame is light and compact, whereas the PVC resin frame of Rion greenhouses has excellent insulation.

Is it necessary to prepare a level foundation for a greenhouse?

The stability and long-term service of a greenhouse relies heavily on the preparation of a firm foundation for placement and fixing (See further advice in “Is it necessary to prepare a level foundation for grounding products” at the General FAQ section). If you install a greenhouse on a ground with low moisture content it is highly recommended to use a ground cover or weed barrier, which will allow water to drain through the fabric while keeping weeds from growing.

How can accessories contribute to greenhouse gardening?

Greenhouse accessories can help you make the most of your greenhouse space by customising it to your specific needs; making gardening more efficient, productive and approachable. Clear floor room by using shelves, use additional vents and louvres with manual or automatic openers to stabilise heat and humidity levels. For complete accessories listing please visit our Accessories page.

How to choose a carport site?

Before installation, consider the car’s route into and out of the carport as well as your route from the car to your house and back. Mark the poles’ location on the ground and make sure the vehicle can safely enter the carport. This is very important when the entryway is curved. Make sure there is enough space for the carport itself. Walls, fences, balconies and trees could become obstacles. For complete Carports listing please visit our Carport page.

Can the carport be re-located?

Yes, the carport can be re-located, even after installation and anchoring it at its final location. Please make sure you do so with at least 2 people.

How is the patio cover installation made flexible?

The patio cover’s structure and design enables a flexible positioning of the poles and wall mounting plate; allowing you to set your required height at the wall connection, the distance from the house and between the poles at the front.
