Hybrid 6' x 6' Greenhouse - Grey Aluminium Frame & Hybrid Polycarbonate Panels
Few things in life are as satisfying as growing your own plants, be it flowers, vegetables, or herbs. Greenhouses offer an ideal growing environment to make that happen and Palram - Canopia makes ideal DIY greenhouse kits. The differences are in the details.
The Hybrid Greenhouse combines two types of polycarbonate panels to create a balanced environment for your plants. Polycarbonate is a virtually unbreakable polymer that provides the light transmission benefits of glass, but is lighter, stronger, and safer.
The diffused roof panels are made of 4mm twin-wall polycarbonate, which have twice the heat retention of single layer panels and allow the light to reach your plants at all angles for more even sunlight and growth while preventing plant burn. The side panels are translucent polycarbonate, providing over 90% light transmission, while blocking harmful UV rays.
Both the panels and the aluminium frame are engineered to be extremely durable, resistant to harsh weather, and maintain their high quality. This attention to detail continues with an integrated gutter system for drainage as well as a roof vent and hinged door to provide airflow and allow adjustment of heat, humidity, and ventilation.
We know it may feel intimidating to put together a greenhouse which is why the Hybrid is designed as a ready to assemble DIY project, with no special tools needed.
Extend your growing season and display your plants while protecting them from harsh sunlight with a hybrid-glazed greenhouse kit!

Frequently Asked Questions
1. Do your products come with a warranty?
Yes, all Gradwell Group products come with a manufacturer’s warranty for your peace of mind. Warranty periods vary depending on the product type, but most of our aluminium and GRP ranges offer 10–25 years of coverage against structural defects, corrosion, or weathering.
2. Can you deliver anywhere in the UK?
Absolutely. We offer UK-wide delivery on all products, including large or heavy items such as carports, patio covers, and conservatories. Delivery times may vary based on location and product availability, but we’ll always keep you updated every step of the way.
3. Do I need planning permission for your products?
In most cases, our products do not require planning permission—especially for carports, door canopies, patio covers, and roofline items. However, we always recommend checking with your local planning authority for large installations or if you live in a conservation area or listed building. Our team can provide specifications to assist with your application if needed.
4. Can I install the product myself or do I need a professional?
For larger structures like aluminium carports or lean-to conservatories, we recommend using a qualified installer for best results. We can also arrange professional installation services through our trusted partners.
