Cladding
Outstanding, 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 [4] 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 [5], as well as being used on 42% (185 of 436) of the top 10% of sheds [6]. Even though the Expert Score of this particular shed is 4 points below that of the average shiplap tongue & groove clad 15′ x 10’s (they have an average Expert Score of 86), 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 47% of 15′ x 10′ sheds (92 in total) [7].
The walls are 12mm thick and we rate this the best thickness out of the 7 found on same-size sheds [8]. It is used on 54% of all sheds [9] and is also used across 58% of the top 10% of sheds [10] we analysed. Even though the Expert Score of this particular shed is 5 points below the average 12mm clad 15′ x 10’s score of 87, the fact that 58% of the top 10% use a cladding this thick is reassuring as a sign of quality. 56% of 15′ x 10′ sheds (109 in total) use 12mm thick walls [11].

Roofing
Tongue & groove is the cladding used for the roofing, our experts rate this the best form of roof material out of the 3 types we’ve found on same-size sheds [12]. 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 5 points below the average of 87 for 15′ x 10’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. 60% of 15′ x 10′ sheds (117 in total) use tongue & groove construction for the roof.
A 12.0mm thick roof boarding was used on this shed which is one of the best thicknesses used for a roofing material out of 10 thicknesses identified on same-size sheds [13]. It’s used on 3% of all sheds and 5% of the top 10% of sheds. Even though the Expert Score of this particular shed is 4 points below that of the average for 15′ x 10’s that use 12.0mm roofing (82 vs the average of 86), you can be sure it’s not due to the roof thickness as this one of the highest scoring thicknesses available on 15′ x 10′ sheds. 7% of 15′ x 10′ sheds (14 in total) use a 12.0mm thick roof boarding.
Mineral felt is used as the roof covering, and out of 3 types identified on same-size sheds [14], is said to be one of the best roof covering materials. It comes fitted on 22% of sheds and used on 49% of the top 10% of 15′ x 10′ sheds. Even though the Expert Score of this particular shed is below the average 15′ x 10’s cover their roofs with mineral felt (82 vs the average of 85), with it being on 49% of the top 10%, this should give you confidence in its quality. 17% of 15′ x 10′ sheds (33 in total) make use of a mineral felt material as a roof covering.

Even though the Expert Score of this particular shed is 5 points below the average of 87 for 15′ x 10’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. 59% of 15′ x 10′ sheds (115 in total) use tongue & groove 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 10 found on same-size sheds [16]. 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 15′ x 10’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. 50% of 15′ x 10′ sheds (98 in total) use 12mm 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.

We found at least 3 sheds that have options that you might find a better fit if this is a concern you have.

1. Dip Treated: Dip treating is a temporary protective base coat treatment that is mainly designed to help protect the building during transit and for around one month after it is assembled. This water-based treatment is the least time-consuming and cheapest type of wood treatment. It involves dipping the wood in a protective water-based preservative and then leaving it to dry. The action of dipping is where ‘dip treatment’ comes from.
A dip-treated garden building is not considered fully treated with wood preservatives; it’s vital to re-treat your dip-treated building, preferably with a solvent-based (or oil-based) wood treatment. Then re-treat it on an annual basis using a solvent-based (or oil-based) wood treatment.
If you don’t want to treat something on an annual basis then a pressure treated wooden building might be a better option, this is where the wood undergoes a process called tanalisation (pressure treatment) during production. This is where the timber is submerged in specialist wood preservatives (such as Tanalith E, this is actually the origin of the word ‘tanalisation’), the wood then goes into a high pressure vacuum tank to draw out excess moisture and air and force in the preservatives. This deep penetration of the exterior wood protects it from the elements and all forms of insect attack. Wood treated this way can last many years without being re-treated. The Wood Protection Association has a good article/video on this. ↩
2. Styrene (Polystyrene (High Impact) HIPS): Styrene as it is commonly known or High Impact Polystyrene (HIPS) is a very versatile form of plastic. It has a very wide range of uses but for garden buildings styrene is typically used as a budget option for windows.
Styrene is a shatter-resistant material, which is why it is ideal for situations where safety needs to be considered, such as playhouses. This benefit can be offset by a few other drawbacks, unfortunately styrene has a tendency to yellow over time (the technical term is Photoyellowing and it is caused by prolonged exposure to UV Light), the degradation of its polymers over time also causes it to become more brittle.
Another drawback of styrene is its thermal coefficient of expansion (it is 80 x 10-6), this is higher than most other glazing options. This means that as the material heats up and cools it can contract and expand more than other glazing options. This cycle can lead to a loose fit of windows over time.
According to data from the British Plastics Fedaration the physical properties of Styrene (Polystyrene (High Impact) are that it is not very good when exposed to high heat with a maximum continuous use temperature of between 60 to 80 °C. This is coupled with the fairly low range the Notched Impact Strength data shows of 10.0 – 20.0 Kj/m². ↩
3. 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. ↩
