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 walls and is the only type [3] we’ve identified on same-size summer houses, that you’ll also see getting used on 50% (368 of 741) of all summer houses analysed [4], as well as being used on 49% (36 of 74) of the top 10% of summer houses [5]. Even though the Expert Score of this particular summer house is 4 points below that of the average shiplap tongue & groove clad 13′ x 9’s (they have an average Expert Score of 81), with it being on 49% 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 13′ x 9′ summer houses (35 in total) [6].
The walls are 12mm thick and we rate this an about average thickness and is the only thickness found on same-size summer houses [7]. It is used on 78% of all summer houses [8] and is also used across 92% of the top 10% of summer houses [9] we analysed. Even though the Expert Score of this particular summer house is 6 points below the average 12mm clad 13′ x 9’s score of 83, the fact that 92% of the top 10% use a cladding this thick is reassuring as a sign of quality. 95% of 13′ x 9′ summer houses (71 in total) use 12mm thick walls [10].

Roofing
Tongue & groove is the cladding used for the roofing, our experts rate this the best form of roof material and is the only type we’ve found on same-size summer houses [11]. This roofing material is used on 69% of all summer houses analysed, and 81% of the top 10% of summer houses. Even though the Expert Score of this particular summer house is 6 points below the average of 83 for 13′ x 9’s using a tongue & groove roofing, with it being on 81% of the top 10%, you can be assured that this is a quality roof material. 93% of 13′ x 9′ summer houses (70 in total) use tongue & groove construction for the roof.
A 12.0mm thick roof boarding was used on this summer house which is one of the best thicknesses used for a roofing material out of 2 thicknesses identified on same-size summer houses [12]. It’s used on 2% of all summer houses with a further analysis of the top 10% of summer houses (74 in total) showing us that none of them use a roof of this thickness. Our data on all 13′ x 9′ summer houses shows us this is the only one to use a 12.0mm roofing solution.
Mineral felt is used as the roof covering. Our experts say it’s one of the best roof covering materials, and is also the only kind identified on same-size summer houses [13]. It comes fitted on 26% of summer houses and used on 43% of the top 10% of 13′ x 9′ summer houses. Even though the Expert Score of this particular summer house is below the average 13′ x 9’s cover their roofs with mineral felt (77 vs the average of 80), with it being on 43% of the top 10%, this should give you confidence in its quality. 12% of 13′ x 9′ summer houses (9 in total) make use of a mineral felt material as a roof covering.

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. ↩
