Cladding
Outstanding, our experts say most of the cladding options used are among the best.
The interlocking log cladding(walls) used here is the best form of construction for shed walls out of the 2 types [1] we’ve identified on same-size sheds, that you’ll also see getting used on 1% (22 of 4,360) of all sheds analysed [2], as well as being used on 2% (8 of 436) of the top 10% of sheds [3]. While you’ll find that the Expert Score of this shed is 4 points lower than the average for interlocking log clad 18′ x 13’s (80 vs the average of 84) [4], you can be sure it’s not due to the cladding as this one of the highest scoring materials found on 18′ x 13′ sheds. You’ll also find the interlocking log cladding showing up on 3% of 18′ x 13′ sheds (3 in total).
The walls are 44mm thick and we rate this the best thickness out of the 5 found on same-size sheds [5]. It is used on 1% of all sheds [6] and is also used across 1% of the top 10% of sheds [7] we analysed. While you’ll find that the Expert Score of this shed is 7 points lower than the average for 18′ x 13’s that use 44mm thick cladding (80 vs the average of 87) [8], you can be sure it’s not due to the cladding thickness as this one of the highest scoring thicknesses available on 18′ x 13′ sheds. 4% of 18′ x 13′ sheds (4 in total) use 44mm thick walls.

Roofing
Tongue & groove is the cladding used for the roofing, our experts rate this the best form of roof material out of the 2 types we’ve found on same-size sheds [9]. This roofing material is used on 34% of all sheds analysed, and 57% of the top 10% of sheds. Even though the Expert Score of this particular shed is 6 points below the average of 86 for 18′ x 13’s using a tongue & groove roofing, with it being on 57% of the top 10%, you can be assured that this is a quality roof material. 73% of 18′ x 13′ sheds (71 in total) use tongue & groove construction for the roof.

It’s used on 1% of all sheds and 3% of the top 10% of sheds. Even though the Expert Score of this particular shed is 4 points below that of the average for 18′ x 13’s that use 16mm roofing (80 vs the average of 84), you can be sure it’s not due to the roof thickness as this one of the highest scoring thicknesses available on 18′ x 13′ sheds. 3% of 18′ x 13′ sheds (3 in total) use a 16mm thick roof boarding.
Mineral felt is used as the roof covering, and out of 2 types identified on same-size sheds [11], is said to be one of the best roof covering materials.

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.

1. Untreated: Any wooden structure that is left untreated will have its lifespan dramatically shortened. This is especially the case with Douglas fir or European softwoods such as Whitewood (spruce) or Redwood (Pine), most garden buildings sold in the UK are made from such wood.
The Wood Protection Association says that “the risk of attack increases significantly if the moisture content of wood, for any reason, rises above 20%” they also talk about how more lower durability cuts of wood (known as sapwood) are getting used to build with than in years gone by. They also say that “sapwood on the other hand is a source of food for many species of fungi and insects and is always vulnerable to attack.” This risk is particularly prevalent with European softwoods.
The BS 8417 code of practice (this advises on the choice of timber species and the use and application of wood preservatives) and BS EN 350:2016 (this advises on methods for determining and classifying the durability of wood and wood-based materials against biological wood-destroying agents) says the natural durability class of such European softwoods is between 3 and 5. With class 3 listed as moderately durable, class 4 listed as slightly durable and class 5 listed as not durable. All three classes have a service life of less than 15 years in a frequently wet environment (such as a UK garden). Yet the application of a preservative treatment or modification of lower durability species is designed according to BS8605 part1 (this is the British standards specifications for external timber cladding) to extend service life to 15/30 years or more.
Having a wooden garden structure supplied as untreated is relatively rare. The vast majority of wooden buildings are supplied with some form of basic treatment, usually a short term water based dip treatment. If you buy an untreated wooden building/structure then we strongly advise that you treat it annually with a solvent-based wood treatment. For full penetration it requires 2-3 coats. It is also recommended that you treat the inside of the structure as well.
If you are wanting something that will require much less maintenance throughout the products life cycle then we would strongly suggest looking at something that is pressure treated also known as tanalised timber.
By correctly treating timber you can take a sub 15 year service life for a not very durable European softwood and extend its service life to 15/30 years or more according to the Timber Decking and Cladding Association. ↩
