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 4 types [2] 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 [3], as well as being used on 42% (185 of 436) of the top 10% of sheds [4]. You’ll also find the shiplap tongue & groove cladding showing up on 29% of 6′ x 9′ sheds (85 in total) [5], and when taking the average Expert Score of those 6′ x 9′ sheds (90), the Mercia Insulated Garden Room 2x3m Installed is the same with an Expert Score of 90.

The walls are 72mm thick and we rate this the best thickness out of the 13 found on same-size sheds [6]. It is used on 1% of all sheds [7] and after analysing the top 436 products that make up the top 10% of sheds [8], we don’t find this thickness present on any of them. 1% of 6′ x 9′ sheds (4 in total) use 72mm thick walls [9], and when taking the average Expert Score of those 6′ x 9′ sheds (89), the Mercia Insulated Garden Room 2x3m Installed is just above the average with an Expert Score of 90.

It comes fitted on 1% of sheds and used on 1% of the top 10% of 6′ x 9′ sheds. 1% of 6′ x 9′ sheds (2 in total) make use of an epdm synthetic rubber material as a roof covering, and when taking the average Expert Score of those 6′ x 9′ sheds (88), the Mercia Insulated Garden Room 2x3m Installed is just above the average with an Expert Score of 90.

This type of floor construction is used on 36% of all sheds we analysed, and 59% of the top 10% of those sheds. 35% of 6′ x 9′ sheds (105 in total) use tongue & groove construction for the floor.

We found 256 6′ x 9′ sheds with comparable specifications. The Mercia Insulated Garden Room 2x3m Installed has an Expert Score that is 2% higher than average and is £287 more expensive than average. If you are looking for the best value or highest expert scoring sheds out of the 256 with comparable specifications the following might be of interest.

Best value – If you are looking for something comparable that costs less, then you could save £7,349 with this Optional extra – Add top coat Alderney 7′ x 7′ Dip Treated Shed Double Door with One Opening Window Top Coat. It is priced at £151, this is 4856% less than this and has an Expert Score of 87, 2 points less than the Mercia Insulated Garden Room 2x3m Installed.

Highest Expert Score – With an Expert Score of 100 vs 90 for this product, the Oren 10′ x 6′ Shiplap Pent Bike Shed is the best 6′ x 9′ shed with comparable specifications, and is priced at £864, that’s £6,636 less than the Mercia Insulated Garden Room 2x3m Installed.

High Wind Area – If you live in a particularly exposed or high wind area then having a shed with a thicker cladding and higher than average frame thickness can be preferable. We found at least 3 sheds that have a combination of features that can make them more suited to higher wind areas.

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.

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

2. FSC Certified Timber: The Forest Stewardship Council (FSC) is an international organisation that is “dedicated to promoting responsible management of the world’s forests.” When you see the FSC certification it means the forest where this wood was sourced from is being managed in a way that preserves biological diversity, while ensuring it sustains economic viability. FSC-certified forests are managed to strict environmental, social and economic standards. FSC certified timber is comparable to Certified Timber
