Ridge ventilation

Air circulation starts low down in our greenhouse but hot exhausted air can escape through the handsome full length ridge vents, located on both sides of the greenhouse for optimum air flow. Plants love air movement, you will be rewarded if you offer plenty of fresh air. To this end our vents are automated with heat sensitive cylinders and strong spring mechanisms. 6mm toughened clear glass panels allow maximum light and the openers allow maximum ventilation.

Accoya Framework

We are proud to manufacture with Accoya. It is an acetylated wood that has been thoroughly tested for dimensional stability and durability, guaranteed for 50 years untreated and even given a 70 year service life by TRADA. Accoya is so strong that it is used in the construction of bridges and even to line canals. Accoya is produced from fast growing renewable, well managed sources and as such has a low, even negative carbon footprint. Organically treated Accoya carries a prized FSC certification.

Wooden Greenhouses

Our modern take on traditional wooden greenhouses has been influenced by changes to the types of wood and their availability. For instance, greenhouses made of softwoods such as pine and cedar have limited life span, say 10 - 25 years and replacement may be necessary in time.

Hardwoods, such as teak or mahogany, although long-lasting have been exploited in the rainforests and are now rare so definitely ecologically unfriendly. So we have selected Accoya for our framework and boarding. This beautiful timber is from fast-growing sustainable certified wood species. It is treated with a naturally occurring non-toxic product that produces enhanced durability (50 years or more), improves hardness and unbeatable dimensional stability, perfect for traditional craft woodworking.

  • Sustainable, fast growing, certified FSC species
  • Naturally treated for a long life
  • Hard, strong and true – that’s Accoya.

Our wooden greenhouses are all made from Accoya in combination with our own custom aluminium extrusions. Despite the fact that Accoya has a 50 year Guarantee we still space incorporate a discrete aluminium plinth to keep the wood from being in contact with your base. With our strong aluminium door frame we've eliminated the problems associated with wooden greenhouse doors than have a tendency to warp due to the extreme difference in temperatures between inside and outside the greenhouse. Frameless roof vents allow water to run off without pooling whilst the neat powder coated aluminium rainwater goods capture rainwater for collection should you choose.

Water collection

A reliable source of pure water

High capacity, strong aluminium gutters will carry the rain from your greenhouse roof to provide the water that will ensure your plants will thrive. Our securely fixed gutter and downpipes which can be adjusted to length will allow you to collect this precious commodity in your waterbutt. Whether you choose to collect or discharge the water Cultivar provide the means.

Frames

Our unique glasshouse frames

Wide 750mm toughened safety glass panels set into slim aluminium frames give plants the warmth, light and ultraviolet light required for promising propagation. The frames are designed based on modern sophisticated window frame principles but miniaturized to allow more light. The glass rests between EPDM gaskets which allow the glass to expand when it gets hot but makes sure the glass is securely and snugly held in place with no rattles. The framework is powder coated in quartz grey, RAL7039, for a maintenance free finish.

Traditional look

Modern materials

Accoya is not only attractive, maturing to a grey patina, but is long lasting and dimensionally stable. The perfect tongue and groove boarding is machined to our exclusive design as we need consistency of quality and boards that will not warp, twist or bow. Twinned with automated low level ventilation the Plant House is both good looking and talented.

Low level ventilation

Full length even air flow

Automated vents located at the plinth level run the entire length of each side of the greenhouse, providing more than enough ventilation. These automated flaps will provide the very best growing conditions. The autovents react to increased air temperature to ensure that your plants are not exposed to extreme temperatures.

Eaves vents

Frameless and made from toughened safety glass

In the instance that you are building a dwarf wall on which to sit your greenhouse we offer full length eaves ventilation. These run the entire length of both sides of the greenhouse and are operated manually with a simple central opener. Like the roof ventilation these are frameless and made from 6mm toughened safety glass. The edges of the vents are polished and the corners are designed with a radius for safety. Automatic openers can be exchanged for manual openers should you desire.

Staging and shelving

Utility, practicality and versatility

Work benches have never been so thoughtfully designed and have probably never been so strong and versatile. When installed the slatted aluminium surface will support all your plants. You can choose to have the staging down one or both sides depending upon your growing plans. If you would like a softer surface then our aluminium slats can be replaced by Accoya, an aesthetically pleasing, strong and reliable alternative. If you would like a sand bed or pea gravel then that’s no problem, just call us to discuss your needs. You can also buy online a ABS Plastic Tray for the 8 and 10 foot wide models which can be used for potting up or to soak your pots.

There is also a hidden advantage, your staging can be folded down, just remove the tray and it will pivot down in a flash with the external frame. If you prefer you can unhook the staging for complete removal. This will create a space should you wish to grow tomatoes during the summer months. The shelves adopts a similar range of options and facility.

The practical and attractive framework is finished in quartz grey, RAL7039, to co-ordinate with the greenhouse.

The ultimate greenhouse door

Tight Fitting, Soft Closing with Sensible Handles, Locks, Hinges and Hold Backs

Door jammed or loose on it’s runners ? Not with a Cultivar Door. This class beating door wide enough for a wheelbarrow and on the 8 and 10ft models good for wheelchair access with a low threshold. It’s solid aluminium frame elegantly sits within a wooden Accoya framework. Glazed uppermost with toughened safety glass whilst the lower section has heavy duty Accoya wood paneling, it’s designed for a lifetime of hard work.

Not your typical greenhouse door, this one is secure, a high specification Eurolock (with spare keys), a quality handle, inside and out, hinges that will comfortably carry the weight of the door opening to 180 degrees where a push action will keep the door secured back and a pull will release when the day is done.

Safety glass throughout

Clearly the best

Forget delicate 2mm horticultural glass, broken storm damaged panes. Other than boulders there is not much that will break our 4mm toughened safety glass. Captured securely our strong frames and rigid construction will further protect the glass. Like all safety glass it will not shatter into shards but into small crystals which can be swept up. In any case it’s a one in a million chance but easily remedied by a simple replacement method. Designed to last a lifetime 4mm or 6mm toughened safety glass to British Standards is used throughout a Cultivar Greenhouse.

Small details make a big difference

All our roof and wall glazing frames have a groove, seen as a shadow line, known in the trade as a screw port. This has been designed with the grower in mind so you can fix, tie and hang plants or tools securely in position. No drilling required.

Our video shows just how easy this is using two proprietary fixings which can be bought online from the likes of amazon or ebay. A little creative thinking may suggest other solutions and uses. For instance, a simple screw with twine around the head would hold up your tomatoes or your electrician may use P-clips screwed into the groove to route your wiring.

The most important piece of information is however here. The screws should be stainless steel, self tapping, 4.2mm (no.8) gauge. The depth of the groove is 8mm, it cannot be tightened beyond this. A variety of screws may be required to suit your plans.

The parts featured in the video were purchased through ebay using the descriptions below :

  • Nylon Lacing Mushroom secured with
  • DIN7981 Pozi Panhead Self Tapping Screws – 4.2mm by 19mm

Build a base

Matching or contrasting

The traditional dwarf wall greenhouse can be given a new look for the new century. Glazed bricks in a wide choice of colours would create quite a stir if you chose to contrast your new pastime and hobby centre to the appearance of your home. Brick bases can be a sensible but long term choice for the enthusiastic gardener, a sign of serious intent.

Furthermore brick wall greenhouses give a more even temperature throughout the structure, they’re slower to heat up and slower to cool. If you are seeking this option then discuss with your builder the plans for your new greenhouse base.

This dwarf wall greenhouse page might give you some inspiration as to the sort of bricks available.
