Endorsed by the RHS:
The Royal Horticultural Society (RHS) is the UK’s foremost gardening charity, dedicated to making gardening a way of life for all. With a mission to enhance lives through plants, the RHS aims to foster healthier lifestyles, build stronger communities, and create vibrant, sustainable environments. By supporting the gardening journey of individuals at all stages, the RHS strives to make the UK greener and more beautiful. Only the finest licensed products and carefully selected partners receive the RHS endorsement, which recognises Gabriel Ash’s unwavering commitment to quality craftsmanship, attention to detail, and premium materials in their greenhouse designs. Gabriel Ash greenhouses have proudly been RHS-endorsed for over a decade.
Base:
The RHS Portico is supplied with Cedar panels at the bottom level and an aluminium base plinth as standard. However it can also be adapted to be built onto a low dwarf wall, if preferred.
Doors:
The RHS Portico features a central porch entrance with a single hinged door as standard. You are able to choose which way the door opens – to the right or to the left. We will contact you on receipt of your order to discuss this.
Glass:
Toughened safety glass to BS6206 is fitted as standard to all Gabriel Ash greenhouses.
Roof Vents & Louvres:
The Gabriel Ash range of greenhouses do not have roof vents, but rather, sash windows to the sides of the greenhouse. The number increases with the size of greenhouse (please note the following are nominal sizes).
- 14ft & 16ft long with six windows
- 18ft, 21ft & 24ft long with ten windows
Louvres can be added to your order according to your preferences.
Automatic Ventilation:
The Classic and RHS collections are supplied with unique full ridge automatic ventilation. Gabriel Ash Classic and RHS greenhouses have a unique automatic ridge ventilation system which runs the full length of your greenhouse. This provides ventilation at the highest point in the greenhouse where it is needed. This system is operated automatically by wax filled actuators. When it is warm the wax in the cylinders expands pushing the vent up. As above, louvres can also be added to increase ventilation, if required.
Shelving/Staging:
The Gabriel Ash Folding Cedar Shelving and staging is made from solid Western Red Cedar and is usually positioned along the rear of the structure. The shelving is positioned at eye-level and the staging as waist/kitchen counter height. Both the staging and shelving can be folded away when not required, maximising the internal space. Please Note: On all structures with a Dwarf Wall the folding staging will not fold down. This still allows for a large amount of storage under the staging.
Rainwater Collection:
The greenhouse is provided with metal gutters and 1½” (40mm) downpipes that collect rainwater from the roof, preventing runoff and allowing for efficient collection. These standard aluminium pipes are easily adapted to fit water butts.
Panelling:
The RHS Collection is supplied with Cedar panels at the bottom level as standard.
Fixings:
High quality solid brass and stainless steel fixtures.
Finials:
Finials are supplied as standard with the RHS Portico and are positioned on each gable end and the entrance porch.
Blinds:
The Gabriel Ash roller blinds are grey in colour and are specifically designed for greenhouse use, offering a combination of practical shading and easy functionality. These blinds are crafted from durable synthetic materials and are made to fit neatly within Gabriel Ash’s greenhouse structures. This helps to maintain a cooler interior environment, which protects plants from excessive heat during warmer months.
These blinds use a spring-loaded mechanism for convenient adjustment, allowing for flexibility in temperature and light control. They are tailored to fit the cedar framework of Gabriel Ash’s greenhouse models, and are part of their RHS-endorsed collection, aligning with high standards in quality and eco-conscious materials.
Treatment:
Western Red Cedar contains its own natural preservatives, giving your greenhouse a long life span without the need for treatment. Cedar will mellow to a silvery grey over time; if you wish to prevent your greenhouse from greying and maintain or change its original colour we can provide treatments or there are several proprietary brands on the market that are suitable. Western Red Cedar absorbs stains and oils readily. Should you choose to treat your Classic or RHS greenhouse you will not need to get up on the roof of your greenhouse since these are protected by aluminium cappings.
Warranty:
The greenhouse is provided with a 12-year warranty.
