Below is a brief overview of how some of the key points of this greenhouse fairs across the market.

Cladding

The tongue & groove cladding(walls) used here is the best form of construction for walls and is the only type [2] we’ve identified on same-size greenhouses, that you’ll also see getting used on 5% (40 of 787) of all greenhouses analysed [3], as well as being used on 12% (9 of 78) of the top 10% of greenhouses [4]. While you’ll find that the Expert Score of this greenhouse is 1 point lower than the average for tongue & groove clad 26′ x 6’s (67 vs the average of 68) [5], you can be sure it’s not due to the cladding as this one of the highest scoring materials found on 26′ x 6′ greenhouses. You’ll also find the tongue & groove cladding showing up on 15% of 26′ x 6′ greenhouses (4 in total).

The walls are 12mm thick and we rate this an about average thickness out of the 2 found on same-size greenhouses [6]. It is used on 5% of all greenhouses [7] and is also used across 13% of the top 10% of greenhouses [8] we analysed. 15% of 26′ x 6′ greenhouses (4 in total) use 12mm thick walls [9].

It’s used on 4% of all greenhouses and 3% of the top 10% of greenhouses. Even though the Expert Score of this particular greenhouse is 1 point below that of the average for 26′ x 6’s that use 12mm roofing (67 vs the average of 68), you can be sure it’s not due to the roof thickness as this one of the highest scoring thicknesses available on 26′ x 6′ greenhouses. 15% of 26′ x 6′ greenhouses (4 in total) use a 12mm thick roof boarding.

Public-Facing – Extra security measures might be more of a concern if you’re placing your building in an area that is more public-facing than a garden. Features such as security windows or even having no windows at all, and the ability to lock all opening doors are usually much more important when you have something that is more public-facing. We found at least 3 greenhouses that have options that you might find a better fit if this is a concern you have.

1. Pressure Treated: Considered the most durable wood treatment, this is where the wood undergoes a process called tanalisation. This is where the timber is submerged in specialist wood preservatives (such as Tanalith E, this is actually the origin of the word ‘tanalisation’), this is a unique combination of copper and organic biocide ingredients (it is the copper that gives the finished wood the slightly green colour). The wood then goes into a high pressure vacuum tank (the Wood Protection Association has a good article/video on this) to draw out excess moisture and air and force in the preservatives.

This deep penetration of the exterior wood protects it from the elements and all forms of insect attack. Wood treated this way can last many years without being re-treated. The BS 8417 code of practice (this advises on the choice of timber species and the use and application of wood preservatives) says “ penetration to either 6 mm (15 years) or 12mm (for 30 years) has to be achieved in any exposed surface in sawn material.”

It is also worth noting that if cross cutting, notching or boring treated timber during or after installation, ALWAYS apply an end grain solvent-based (or oil-based) wood preservative treatment to the freshly exposed areas, this will maintain the integrity of the protection. NEVER put cut ends in the ground, even if end grain coated.
