Frequently Asked Questions

Yes, our solar-powered roof vents will automatically open at a set temperature.

In strong winds, it is best to dis-engage the cylinders and engage the roof vent locks. Here is a brief list of what you need to do when you want to lock your roof vents. The roof vent openers need to be de-activated BEFORE you lock your roof vents. Locking the roof vents without this could cause damage to your auto openers and potentially damage your roof vents.

• Remove the pin from the auto vent
• Once pin is removed, lift the roof vent up slightly so that the cylinder drops out of the black cup
• Unscrew the cylinder
• Repeat on all other openers
• Now you can lock them down to help prevent damage
• Keep cylinders stored in a cool place until needed, cool in fridge before refitting
• Remember to slide locks up out of the way when refitting cylinders
• If you have difficulties removing the cylinder you could remove the bracket from the vent cross bar so the opener is not connected to the frame on the window sill (vent cross bar) the bracket will need re-fitting once ready for the openers to start working.

Lets face it, as we live in the UK storms are likely! We've written a great guide around how to keep your Rhino secure in a storm. 

We've written a handy guide on the best way to insulate your greenhouse. Hint... it may involve bubble wrap!

For maximum strength and safety we use 4mm toughened safety glass on all our Rhino greenhouses.

Yes, while the 4mm toughened safety glass is much stronger than standard horticultural glass, it can still break. In the unlikely event a of a breakage, we can provide replacement panes.

As with any item left outdoors like cars, furniture and lights, there may be a small amount of colour change over time. We work closely with our paint partners to help ensure that any colour change is minimal and please note that this does not affect the performance of the product. 

Regular cleaning and polishing will help to maintain the life of the colour. For non-painted greenhouses, you can expect to see some natural colour change and blooming over time.

We have a handy guide on how to carry out regular maintenance. But you'll also need to check fixings throughout your greenhouse periodically, or after a severe storm. Clear any debris from gutters & downpipes. Clean your greenhouse at least once a year with warm soapy water (refer to greenhouse cleaning guide on website). Spray automatic roof vent openers with 3 in 1 oil or similar to prevent them seizing. 

All Rhinos are aluminium greenhouses. The use of aluminium ensures that Rhinos stand tall and stable in the face of many a storm, providing their 25 year guarantee. 

If you are moving and want to take your greenhouse with you, you can. In order to do this you'll need to detach the automatic openers from the roof vents. This will allow you to slide the roof vents off. Next the doors will need to be slid off, to do this you will first have to remove the door stops which are located on the door posts. You then need to remove the door support which attaches to the top of the door track and at the eave/gutter.

Once the doors and vents are removed you can then deglaze, you can remove the beads carefully with long nose pliers and a flat edge screwdriver, alternatively you can Stanley knife down the centre of the bead and pull the beads out and buy a new set of beads for when you re-build, please contact service@greenhousesdirect.co.uk for a quote. Once deglazed you can then remove your roof sections, once the roof is dismantled you can then take the four sections apart by undoing the base plates and fixings.
