Cladding

Fantastic, 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].

A 12mm thick roof boarding was used on this shed which is one of the best thicknesses used for a roofing material out of 5 thicknesses identified on same-size sheds [11]. It’s used on 29% of all sheds and 48% of the top 10% of sheds. Even though the Expert Score of this particular shed is 8 points below that of the average for 19′ x 9’s that use 12mm roofing (80 vs the average of 88), with it being on 48% of the top 10%, this should give you confidence in its quality. 73% of 19′ x 9′ sheds (107 in total) use a 12mm thick roof boarding.

Coastal Consideration – If you live in a particularly wet or harsher environment such as by the coast then you might want to consider something with a more robust pressure treatment or something made from metal or plastic, both materials that are particularly suited to such harsh environments. We’ve found at least 3 sheds that have a combination of features that can make them more suited to higher wind areas.

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 sheds that have options that you might find a better fit if this is a concern you have.

More Child Friendly – If you have children and you are looking for something that has that little extra in terms of durability then tougher glazing options might be a better option. Here we have at least 3 other options that will fill those needs.
