Castle Balvenie Greenhouse

Castle Balvenie 5ft 3in x 6ft 3in

The Castle Balvenie is one of the best proportioned greenhouses in our range. At 5'3" wide it is ideal for smaller gardens. The double doors give ample access over the low threshold. This is a unique design which avoids the trip hazard of a metal base plinth found on many other types of small greenhouse.

The Balvenie has a range of other features as standard that you don't normally find ... for instance it has a door lock, tubular bracing at the ridge for additional strength, diagonal bracing on the sides and the roof to keep it square and sturdy, and high eaves which make it a comfortable greenhouse for taller gardeners too! The downpipesare a standard feature which are generally an additional cost item with other greenhouses on the market.

Exclusively available from GBC in either plain aluminium finish or 'Old Cottage Green' coloured finish, please click on the 'where can I see one' tab on this page to find out where your nearest display site is or follow the links through to buy this building online today.

The Balvenie 5'3

The Balvenie is one of the best proportioned greenhouses in our range. At 5'3" wide it is ideal for smaller gardens. The double doors give ample access over the low threshold. This is a unique design which avoids the trip hazard of a metal base plinth found on many other types of small greenhouse.

The Balvenie has a range of other features as standard that you don't normally find ... for instance it has a door lock ( ever more important in this day and age ), tubular bracing at the ridge for additional strength, diagonal bracing on the sides and the roof to keep it square and sturdy, and high eaves which make it a comfortable greenhouse for taller gardeners too ! The downpipes are a standard feature which are generally an additional cost item with other greenhouses on the market.

Double box section corner bars

The Castle range is sturdy, strong and will last a lifetime. Part of the reason for its strength is illustrated here - the corner bars ( uprights and eave slopes ) have a double box section arrangement which adds a huge amount of rigidity to each profile.

Compare this to the cheap aluminium framework on other greenhouses which may fold up in bad weather conditions.

Castle staging

Castle staging is available to fit all models in the range or, given that is freestanding, it can be used in any greenhouse or other garden building.

Four widths are available : 12" (31cm) , 18" (47cm),  24" ( 57.5cm) and 30" ( 75cm)

We have a choice of two tier (31", 77 cm high )or three tier (37", 93 cm high )in each width.

Framework can be mill finish as pictured or 'Old Cottage Green'.

2ft (57.5cm ) and 4ft ( 113.5 cm ) long packs are available for the 3 smaller widths. The 30" wide staging is available 4ft long only.

Using a combination of different lengths and widths you can optimise the use of the space inside your new greenhouse.

If bought at the same time as your new Castle or Peak greenhouse there is no delivery charge but if you wish to buy the items separately there will be a small charge to pay per delivery.

'Chartley' Integral staging and shelving

This optional staging and shelving has been designed for the Castle greenhouse range and helps maximise the working area within the greenhouse. You can set the height of the staging when first installed to suit your needs and, if necessary, adjust that level at a later date.

The cantilever supports leave the space beneath the staging free from staging legs and therefore easy to sweep out and use for storage.

It's available in plain mill finish or in 'Old Cottage Green' coloured finish.

*Please note - all green finish buildings are now supplied in 'Old Cottage Green'. The previous 'Classic Green' colour has been discontinued*

Low threshold entry

Walk into most other suppliers' greenhouses and you'll have to step over a base plinth which restricts your ease of entry. This is because their metal bases are sold as an extra item for your greenhouse frame to sit on top of.

Not so with our Castle greenhouses where an integral 4inch ( 100mm ) high base plinth is provided as part of the kit. This is suitable to install on any firm, level area. In the doorway, however, we use a threshold plate at ground level so that the doors are taller and you can walk in without restriction. This is a far better design feature than most other suppliers.

Shown here on a single door Castle greenhouse, the principle is just the same with our double door models.

*Please note - all green finish buildings are now supplied in 'Old Cottage Green'. The previous 'Classic Green' colour has been discontinued*

Door lock

In this day and age, when garden tools and equipment cost so much ( not to mention the value of your plants ) it's important to provide some basic security with your greenhouse.

This lock is a standard feature of this model and is supplied with two keys.

Rainwater pipes and outlets

All that precious rainwater going to waste ?

Castle greenhouses have a downpipe set as a standard feature, something found generally on only the more expensive greenhouses.

Freestanding greenhouses have two stop ends for the integral gutters, two 90 degree outlets, downpipes, retaining clips and a 45 degree knuckle to turn the pipe towards a barrel ( not included ) or just to direct the water away from the framework.

Lean-to models have one downpipe and the associated components.

You will need to provide adequate storage vessels ...plastic barrels for instance. At GBC we can supply these for you, just ask for details of prices!

Tubular roof braces

Castle greenhouses have diagonal bracing in the sides and roof to keep the framework square and sturdy but they also have additional tubular roof bracing which gives extra strength and rigidity to the whole structure.

Roof vents and automatic openers

All of our Castle greenhouses include at least one manually operated roof vent and, the bigger the greenhouse gets the more we supply !  Our catalogue details how many are supplied with each model but, if you feel you need more, this isn't a problem either as we can add additional vents on most sizes.

The picture shows an automatic opener which can be supplied at additional cost.

Automatic vent openers come in many shapes and sizes but the 'Classic' shown is a good,sturdy and well proven opener.

Imagine getting up on a hot summer morning to find everything in your greenhouse has keeled over from the heat ... this is what an automatic opener will help prevent.

As the temperature rises the roof vent will open to ventilate the greenhouse and protect your valuable plants.

5 blade louvre window

An optional, and very useful, accessory is our Castle 5 blade louvre window which is glazed with toughened safety glass.

We recommend fitting them at a low level to draw air up through the greenhouse roof vents thus preventing stale air causing mildew..

Automatic openers are available, also at an additional cost, for the louvre window(s).

Available in plain mill aluminium finish or in 'Old Cottage Green'.

Nut caps

Every detail of the Castle Greenhouse range has been carefully thought out to ensure the greenhouse performs well and looks good.

One of the finishing touches which you'll generally see only on much more expensive buildings are the nut caps as pictured. ( a standard feature with Castle models )

These are in white on the aluminium finish models and black on the green ones.

Bar capping optional upgrade

The pictures here illustrate the option of PVC bar capping which is available in green or white.

It replaces the stainless steel clips which are the normal method of securing the glass.

It makes cleaning much easier and keeps the glass very secure in the framework.

Winter Insulation

Insulating aluminium greenhouses to retain heat for overwintering tender plants and starting off new seedlings can be accomplished by using bubblewrap. This is usually pegged to the frame on the roof as well as the sides and gables but a customer sent in this picture of his solution to the pegging problem :

I have fixed the bubble insulation using three lengths of 13mm aluminium tube cut to length and suspended at the ends from the roof. The bubble wrap then just feeds up and over and down in one piece. It doesn’t require any pegging at all. It then just requires about eight pegs only, to fix the cut and shaped two end pieces. The tube can remain insitu throughout the year .

His building is a 6 x 5 Castle Balvenie but the principle would apply for any other model. Don't forget to disconnect autovents before you fit the bubblewrap or you'll lose all that lovely warm air !

Waterbutt and stand

This is a great way to conserve precious rainwater. Castle greenhouses have a built in gutter and downpipes which can be connected to any rainwater butt.

We sell water butts in two sizes : a slimline 100litre butt as pictured or a 210litre butt. Each has an optional stand which is also shown in the picture.

The pictured greenhouse is from our Peak range which you can view on this website or at our branches.
