The Tilbury 2'2 x 4'3 in Mill finish

The Tilbury is ideal for a limited space on the side wall of a house or at the rear of the garage. At 2'2" deep, and with 3 lengths available, 4ft, 6ft and 8ft nominally, it is surprising just how much you can grow!

The single door gives ample access in the 4ft and 6ft models while the 8ft length has a double sliding door.  

The Tilbury has a roof vent, downpipe, diagonal bracing and base plinth as standard.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.

Brand new for 2018, the old 'Classic Green' colour has now been replaced with the popular and contemporary 'Old Cottage Green' coloured finish.

This new coloured finish ensures this greenhouse will now fit all garden styles; whether you have a traditional English country garden or a modern and contemporary design, this greenhouse will blend into both beautifully.

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.

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.

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!

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 automaic 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.

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.

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 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.

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 !
