Meet the Makers
You’ll love having a Rhino in your garden - it’s the perfect environment for your plants and looks beautiful. It’s also very strong and safe for you and your family.
We care about quality. We design and manufacture the Rhino in our own UK factory and sell direct to the public. We think this makes the Rhino the best value greenhouse money can buy. See what you think.
Included as standard with the Rhino Premium 8x20 greenhouse:
- 4 Triple Roof Vents
- 5 Side Louvre Vents
- 8 Automatic Roof Vent Openers
- Storm Locks
One of our largest greenhouses, the Rhino Premium 8x20 is fitted with as as much roof ventilation as possible to help you control the temperature inside your greenhouse. Each triple roof vent is fitted with solar-powered automatic vent openers. These openers allow the vents to open and close a set temperatures, so if you go away for a couple of days you don't have to worry about your greenhouse.
Vents on our Rhino Premiums are also fitted with storm locks, allowing vents to be secured down. This is ideal when bad weather is expected, allowing the entire structure to be made airtight. Note that it is important to disengage the vents before putting the storm locks into position, to avoid causing any damage to the openers.
You can't achieve optimal ventilation without some louvre vents. Which is why our Rhinos are fitted with high quality Rhino five-blade louvre vents. These vents help you take complete control of airflow, allowing cool air to enter from the side, circulate up through the greenhouse before forcing air to escape through the roof vents.
Adequate ventilation is absolutely crucial to successful growing under glass. There is not another greenhouse on the market that has more ventilation than a Rhino. And the cherry on top? It's all included in the price.
We've produced a handy guide explaining why ventilation is so important and how to optimise your greenhouse temperature.
Keep yourself and your family safe with Rhino's combination glazing system: Toughened Safety Glass and Rubber Glazing Beads. Perfect for exposed locations and families with young children and pets.
Safety is important to us which is why we chose to include our Rhino Tuff 4mm toughened safety glass as standard with every Rhino greenhouse. We could have gone with cheaper alternatives or even horticultural or polycarbonate glazing but additional safety as well as the strength provided by our toughened safety glass made it an easy decision. Our Rhino Tuff 4mm toughened safety glass is 33% thicker than most greenhouse glass. The Grade A glass panes are designed with safety in mind, meaning breakages are less likely while ensuring that, if broken, the glass will shatter into lots of tiny pieces rather than big shards that are far more likely to cause injury. Even the edges of the glass are rounded so that you don’t cut yourself during installation.
The unique Rhino glazing system locks each pane of glass in place along its entire length, using long rubber beads. The glass cannot be blown or sucked out of the frame and pushing on the glass only locks the beads more tightly into the frame, making it ideally engineered for high winds and other extreme weather conditions. With Rhino's glazing method, each pane becomes integral to the strength of the whole frame. The Premium range also features box-section glazing bead for even greater stability, as a step up from the Classic range.
When compared with the glazing that comes as standard on most greenhouses, the Rhino ranges come up trumps every time. No dangerous horticultural glass or flimsy W-clips here; and with the smooth finish achieved by our glazing beads, there's no need for bar capping either.

If we had any doubts about the strength of a Rhino greenhouse we wouldn’t sit on the roof! The Premium range builds on the already great strength of the Rhino Classic with box section glazing bars and 3mm thick 'T' section bracing throughout.
Did you know, each Rhino frame has around 60% more aluminium than similarly priced models. But it’s not just the weight, it’s the clever design of the Rhino that provides it’s inherent strength.
We wanted to make sure that the Rhino could stand up to whatever the Great British weather may throw at it so we tested the snow loading capacity of a Rhino by putting half a tonne of sand bags on the roof!
Rhinos currently inhabit much of the UK, including windy corners from Cornwall to Scotland, and further afield in the Falklands. Customers have told us that they’ve withstood winds of 137mph – could there be a better test?
Every Rhino greenhouse includes a strong aluminium base in the price, which not only provides an incredibly strong foundation but also allows The Rhino to be erected simply onto firm, level soil – so there’s no need for an expensive concrete base.
Once The Rhino is erected, strong stainless steel ground anchors are concreted into position.
The Rhino can also be erected onto a hardstanding of concrete or paving slabs, in which case the stainless steel anchors are fixed using the expansion bolts provided.
All Rhino greenhouses now include a low threshold door and ramp within the price. There’s no longer a trip hazard at the doorway and on 8, 10 and 12ft wide models there is plenty of width for a wheelchair or wheelbarrow to enter with ease.
Every Rhino greenhouse comes with two hanging basket rails.
The roof is so strong that it can easily handle this extra load, and it’s a really useful feature. Your hanging baskets will thrive and it will also free up lots of space on your staging.
Every Rhino greenhouse also comes with large integral gutters as well as downpipes and bends so you can collect and use the natural rainwater that your plants love. Should you wish to combine both gutters into one to feed a single water butt we have a two-in-one kit for that too.
Nothing says more about the quality of a Rhino greenhouse than our 25 Year Guarantee.
A generation of gardeners can rest assured that the frame and even the powder coated colour finish are covered, in the unlikely event that the greenhouse fails.
Unlike most other greenhouse brands, our Rhinos can be erected on soil. This is only due to the strength created by its sturdy base and framework. A soil base should be level and fully compacted, freshly dug soil will shift too much and isn't suitable for use as a stable foundation.
Alternatively, as long as they're smooth and level, hardstanding bases are also suitable. Paving slabs, concrete bases and brick or block perimeter plinths can be used.

This Rhino Premium greenhouse stands at 8ft 4ins wide and 20ft 5ins long with a ridge height of 8ft 4ins.
Every Rhino greenhouse is delivered with a comprehensive set of instructions. With help at key moments, a competent DIY enthusiast can erect this size of greenhouse over a weekend.
However, this time and effort can be eliminated by using a professional installer who will quickly and efficiently erect, glaze and anchor down the greenhouse on your pre-prepared site – either soil or hardstanding. See our Guidance Notes on Site and Base Preparation and Installation.
Installer charges for this size (depending on location and exact specification) are from £485.
Tick the use recommended installer box in your basket and once you've placed an order, we will send you relevant details for independent installers local to you, should you wish you to pursue this.
