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 summer house walls out of the 3 types [4] 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 [5], as well as being used on 49% (36 of 74) of the top 10% of summer houses [6]. You’ll also find the shiplap tongue & groove cladding showing up on 56% of 10′ x 8′ summer houses (71 in total) [7], and when taking the average Expert Score of those 10′ x 8′ summer houses (80), the 10×8 Mercia Vermont Wooden Summerhouse is just above the average with an Expert Score of 82.
The walls are 12mm thick and we rate this an about average thickness out of the 2 found on same-size summer houses [8]. It is used on 78% of all summer houses [9] and is also used across 92% of the top 10% of summer houses [10] we analysed. Even though the Expert Score of this particular summer house is 2 points below the average 12mm clad 10′ x 8’s score of 84, the fact that 92% of the top 10% use a cladding this thick is reassuring as a sign of quality. 88% of 10′ x 8′ summer houses (112 in total) use 12mm thick walls [11].

Roofing
Osb is the of construction method used for the roofing, our experts rate this one of the best forms of roof material out of the 3 types we’ve found on same-size summer houses [12]. This roofing material is used on 5% of all summer houses analysed, and 1% of the top 10% of summer houses. 2% of 10′ x 8′ summer houses (2 in total) use osb construction for the roof, with this product having an Expert Score 5% higher than the average in this regard.
A 8.0mm thick roof boarding was used on this summer house which is the worst thickness used for a roofing material out of 4 thicknesses identified on same-size summer houses [13]. It’s used on 2% of all summer houses and 1% of the top 10% of summer houses. 2% of 10′ x 8′ summer houses (2 in total) use a 8.0mm thick roof boarding, with this product having an Expert Score 5% higher than average.
Sand felt is used as the roof covering, and out of 4 types identified on same-size summer houses [14], is said to be one of the best roof covering materials. It comes fitted on 1% of summer houses and when it comes to the top 74 summer houses that make up the top 10% we find none of them make use of this kind of roof covering. According to the data we have on all summer houses, out of the the 10′ x 8’s this is the only one to use a sand felt roof covering.

Flooring
Fantastic, our experts say most of the flooring options used are among the best.
The manufactures of this summer house chose tongue & groove for the floor construction, we rate this the best form of floor construction and is the only type found on this size of summer house [15]. This type of floor construction is used on 78% of all summer houses we analysed, and 86% of the top 10% of those summer houses. Even though the Expert Score of this particular summer house is 1 point below the average of 83 for 10′ x 8’s using a tongue & groove flooring, with it being on 86% of the top 10%, you can be assured that this is a quality flooring material. 91% of 10′ x 8′ summer houses (116 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 2 found on same-size summer houses [16]. It’s found on 72% of all summer houses and used on 82% of the top 10% of summer houses. Even though the Expert Score of this particular summer house is below the average 10′ x 8’s that use 12mm flooring (82 vs the average of 84), with it being on 82% of the top 10%, this should give you confidence in its quality. 84% of 10′ x 8′ summer houses (107 in total) use 12mm thick floor boarding.

We found at least 3 summer houses 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. ↩
