Cladding

Amazing, our experts say most of the cladding options used are among the best.

The shiplap tongue & groove cladding(walls) used here is one of the best forms of construction for shed walls out of the 3 types [1] we’ve identified on same-size sheds, that you’ll also see getting used on 31% (1,373 of 4,360) of all sheds analysed [2], as well as being used on 42% (185 of 436) of the top 10% of sheds [3]. Even though the Expert Score of this particular shed is 10 points below that of the average shiplap tongue & groove clad 13′ x 13’s (they have an average Expert Score of 87), with it being on 42% of the top 10%, its use here is a reassuring sign of a high quality cladding. You’ll also find the shiplap tongue & groove cladding showing up on 59% of 13′ x 13′ sheds (83 in total) [4].

The walls are 16mm thick and we rate this the best thickness out of the 6 found on same-size sheds [5]. It is used on 2% of all sheds [6] and is also used across 3% of the top 10% of sheds [7] we analysed. While you’ll find that the Expert Score of this shed is 2 points lower than the average for 13′ x 13’s that use 16mm thick cladding (77 vs the average of 79) [8], you can be sure it’s not due to the cladding thickness as this one of the highest scoring thicknesses available on 13′ x 13′ sheds. 8% of 13′ x 13′ sheds (11 in total) use 16mm 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 11 points below the average of 88 for 13′ 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. 81% of 13′ x 13′ sheds (114 in total) use tongue & groove construction for the roof.

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 [10]. 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 11 points below that of the average for 13′ x 13’s that use 12mm roofing (77 vs the average of 88), with it being on 48% of the top 10%, this should give you confidence in its quality. 74% of 13′ x 13′ sheds (104 in total) use a 12mm thick roof boarding.

Epdm synthetic rubber is used as the roof covering, and out of 2 types identified on same-size sheds [11], is said to be the best roof covering material. It comes fitted on 1% of sheds and used on 1% of the top 10% of 13′ x 13′ sheds. 8% of 13′ x 13′ sheds (11 in total) make use of an epdm synthetic rubber material as a roof covering, and when taking the average Expert Score of those 13′ x 13′ sheds (76), the Adley 4 x 3m Drayton Insulated Garden Room is just above the average with an Expert Score of 77.

Even though the Expert Score of this particular shed is 11 points below the average of 88 for 13′ x 13’s using a tongue & groove flooring, with it being on 59% of the top 10%, you can be assured that this is a quality flooring material. 76% of 13′ x 13′ sheds (107 in total) use tongue & groove construction for the floor.

It’s found on 3% of all sheds and used on 3% of the top 10% of sheds. Even though the Expert Score of this shed is 3 points lower than that of the average for 13′ x 13’s floored with a 16mm material (77 vs the average of 80), you can be sure it’s not due to the flooring because this one of the highest scoring flooring thicknesses available on 13′ x 13′ sheds. 10% of 13′ x 13′ sheds (14 in total) use 16mm thick floor 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 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
