Our verdict on the Adley 3m x 4m Insulated Garden Room

The Adley 3m x 4m Insulated Garden Room comes with a pent style roof, holds a 15 Years guarantee, fit with double doors, and makes use of certified sustainable materials. The 3 windows used on this particular 10′ x 13′ use a single glazed glazing material (Thickness was not specified).

Base material: timber

Our experts say this has 3 stand out features. A stand out feature is something found on over 70% of the top 10% of products in a particular category or is an exceptionally good feature as rated by our panel of experts.

1. The shiplap tongue & groove cladding used on this shed is one the best available for sheds rated by our experts.

2. A 16mm thick cladding like the one used on walls of this shed is one of the best rated by our experts.

3. The epdm synthetic rubber roof covering found on this shed is rated to be one of the best by our experts.

Below is a brief overview of how some of the key points of this shed fairs across the market.

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 [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 5 points below that of the average shiplap tongue & groove clad 10′ 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 45% of 10′ x 13′ sheds (90 in total) [4].

The walls are 16mm thick and we rate this the best thickness out of the 11 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. 3% of 10′ x 13′ sheds (7 in total) use 16mm thick walls [8], and when taking the average Expert Score of those 10′ x 13′ sheds (81), the Adley 3m x 4m Insulated Garden Room is just above the average with an Expert Score of 82.

Roofing

Epdm synthetic rubber is used as the roof covering, and out of 3 types identified on same-size sheds [9], 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 10′ x 13′ sheds. 5% of 10′ x 13′ sheds (11 in total) make use of an epdm synthetic rubber material as a roof covering, with this product having an Expert Score of 8% higher than the average.

Flooring

The manufactures of this shed chose osb for the floor construction, we rate this an about average form of floor construction out of 2 types found on same-size sheds [10]. This type of floor construction is used on 20% of all sheds we analysed, and 5% of the top 10% of those sheds. 5% of 10′ x 13′ sheds (11 in total) use osb construction for the floor.

A 12mm thick floor boarding is used here, this is one of the best floor board thicknesses according to our experts out of 8 found on same-size sheds [11]. It’s found on 31% of all sheds and used on 54% of the top 10% of sheds. Even though the Expert Score of this particular shed is below the average 10′ x 13’s that use 12mm flooring (82 vs the average of 88), with it being on 54% of the top 10%, this should give you confidence in its quality. 49% of 10′ x 13′ sheds (98 in total) use 12mm thick floor boarding.

If you are looking for the best value or highest expert scoring sheds out of the 150 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 £8,975 with this Adley 15′ x 10′ Windowless Double Door Overlap Apex Workshop. It is priced at £1,284, this is 699% less than this and has an Expert Score of 77, 5 points less than the Adley 3m x 4m Insulated Garden Room.

Highest Expert Score – With an Expert Score of 95 vs 82 for this product, the Redlands 12′ x 12′ Hot Tub Shelter is the best 10′ x 13′ shed with comparable specifications, and is priced at £2,914, that’s £7,345 less than the Adley 3m x 4m Insulated Garden Room.

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.

10′ x 12’4 Yardmaster Balmoral 1012WGL Metal Shed
10′ x 13′ Yardmaster Castleton Anthracite Metal Shed

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.

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
