Cladding
Amazing, our experts say most of the cladding options used are among the best.
The tongue & groove cladding(walls) used here is the best form of construction for shed walls out of the 3 types [2] we’ve identified on same-size sheds, that you’ll also see getting used on 35% (1,543 of 4,360) of all sheds analysed [3], as well as being used on 21% (92 of 436) of the top 10% of sheds [4]. While you’ll find that the Expert Score of this shed is 7 points lower than the average for tongue & groove clad 19′ x 9’s (80 vs the average of 87) [5], you can be sure it’s not due to the cladding as this one of the highest scoring materials found on 19′ x 9′ sheds. You’ll also find the tongue & groove cladding showing up on 32% of 19′ x 9′ sheds (46 in total).
The walls are 12mm thick and we rate this the best thickness out of the 6 found on same-size sheds [6]. It is used on 54% of all sheds [7] and is also used across 58% of the top 10% of sheds [8] we analysed. Even though the Expert Score of this particular shed is 9 points below the average 12mm clad 19′ x 9’s score of 89, the fact that 58% of the top 10% use a cladding this thick is reassuring as a sign of quality. 69% of 19′ x 9′ sheds (101 in total) use 12mm thick walls [9].

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.

We found at least 3 sheds that have options that you might find a better fit if this is a concern you have.

1. Dip Treated: Dip treating is a temporary protective base coat treatment that is mainly designed to help protect the building during transit and for around one month after it is assembled. This water-based treatment is the least time-consuming and cheapest type of wood treatment. It involves dipping the wood in a protective water-based preservative and then leaving it to dry. The action of dipping is where ‘dip treatment’ comes from.
A dip-treated garden building is not considered fully treated with wood preservatives; it’s vital to re-treat your dip-treated building, preferably with a solvent-based (or oil-based) wood treatment. Then re-treat it on an annual basis using a solvent-based (or oil-based) wood treatment.
If you don’t want to treat something on an annual basis then a pressure treated wooden building might be a better option, this is where the wood undergoes a process called tanalisation (pressure treatment) during production. This is where the timber is submerged in specialist wood preservatives (such as Tanalith E, this is actually the origin of the word ‘tanalisation’), the wood then goes into a high pressure vacuum tank 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 Wood Protection Association has a good article/video on this. ↩
