Please Note: Because of the lightweight materials, this greenhouse is not suitable for windy or exposed areas. In these circumstances we recommend a glass greenhouse which is heavier and will remain grounded. This greenhouse is also not supplied with a floor, so for greater stability it should be constructed on an appropriate concrete or slab base.


The colossal 8x20 footprint of this Palram Glory greenhouse makes it just as suitable for commercial use as it is for owners of large gardens who want all the space they can dream of for greenhouse projects. Raise an army of vegetables with this high-quality garden building that has been designed to prioritise the needs of plants. The Glory is packed full of features that show this to be the case, such as built-in guttering that encourages a sustainable irrigation system with the addition of a water butt, and translucent glazing that diffuses harsh sunlight. There are few greenhouses on the market that could pick up the gauntlet thrown down by the Palram Glory when it comes to an appealing blend of functionality, durability, and cost. 


The sheer range of features included with the 8x20 Glory can be overwhelming, but we hope to break it down for you here. The greenhouse's four upper vents open automatically, thanks to an ingenious opener system that uses the ambient thermal energy of your greenhouse to open when the interior is overly warm, and contracts with cooler weather. A secondary mode of ventilation is provided by the louvre style vent at the side, which can let in cooler air while keeping a low profile in the greenhouse wall. 

Another welcomed design feature of the 8x20 Glory is its generous eaves height, which offers over six feet of interior headroom even at the lowest heights, reducing the need to stoop when walking inside – and providing plenty of vertical growing space ready for your homegrown plants to string up. A wide single door also contributes to the ease of accessing your greenhouse, and is ideal for larger items or wheelbarrows. The low-threshold ramp into the greenhouse makes pushing a wheelbarrow or entering by wheelchair all that bit easier.

A couple of other features that will subtly improve your experience of gardening are a brush strip that excludes draughts under the door, and an included guttering system that makes collecting any rain that falls onto the Glory's roof a doddle once a water butt is added.

Behind all of these features is the phenomenal build quality that provides a strong and durable foundation for the greenhouse. The aluminium frame used in the Glory is much thicker than lower-end models and is further supported by bars at roof's ridge and eaves. Rather than using glass – which is heavier and can be prone to shattering – the Glory utilises 10mm thick polycarbonate glazing throughout, slightly flexible and highly resistant to impact. This twin-wall glazing is semi-transparent, in order to diffuse direct sunlight and make sure that shadier spots receive more light. 


Palram have created an exciting range of accessories for those who would like to specialise their greenhouse and ready it for certain projects. For example, those planting in summer might want to consider the Shade Kit as a way to protect plants from the harshest sunlight.

Other accessories, like the Automatic Louvre Opener, simply increase the ease with which you can nurture plants. Another of our favourites is the Drip Irrigation Kit, which can be used to water plants simultaneously via up to 16 droppers. This is great for thirsty plants that thrive on daily attention, when you lack the time to water each plant individually or want to ensure a steady and even stream of water across the greenhouse.
