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 tongue & groove floor material is a great choice and is what we find being used by 94% of the top 10% of log cabins.
2. A 19mm thick cladding like the one used on walls of this log cabin is one of the best rated by our experts.
3. The mineral felt roof covering found on this log cabin 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 log cabin fairs across the market.
Cladding
The interlocking boards cladding(walls) used here is an about average form of construction for log cabin walls out of the 2 types [3] we’ve identified on same-size log cabins, that you’ll also see getting used on 3% (29 of 893) of all log cabins analysed [4], and sadly not present at all on any of the 89 log cabins that make up the top 10% of log cabins [5]. You’ll also find the interlocking boards cladding showing up on 4% of 13′ x 9′ log cabins (6 in total) [6].
The walls are 19mm thick and we rate this one of the best thicknesses out of the 5 found on same-size log cabins [7]. It is used on 18% of all log cabins [8] and is also used across 3% of the top 10% of log cabins [9] we analysed. While you’ll find that the Expert Score of this log cabin is 3 points lower than the average for 13′ x 9’s that use 19mm thick cladding (80 vs the average of 83) [10], you can be sure it’s not due to the cladding thickness as this one of the highest scoring thicknesses available on 13′ x 9′ log cabins. 12% of 13′ x 9′ log cabins (17 in total) use 19mm thick walls.

Roofing
Mineral felt is used as the roof covering, and out of 3 types identified on same-size log cabins [11], is said to be one of the best roof covering materials. It comes fitted on 57% of log cabins and used on 58% of the top 10% of 13′ x 9′ log cabins. Even though the Expert Score of this particular log cabin is below the average 13′ x 9’s cover their roofs with mineral felt (80 vs the average of 86), with it being on 58% of the top 10%, this should give you confidence in its quality. 62% of 13′ x 9′ log cabins (90 in total) make use of a mineral felt material as a roof covering.

Flooring
The manufactures of this log cabin 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 log cabin [12]. This type of floor construction is used on 74% of all log cabins we analysed, and 94% of the top 10% of those log cabins. Even though the Expert Score of this particular log cabin is 7 points below the average of 87 for 13′ x 9’s using a tongue & groove flooring, with it being on 94% of the top 10%, you can be assured that this is a quality flooring material. 79% of 13′ x 9′ log cabins (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 8 found on same-size log cabins [13]. It’s found on 10% of all log cabins and used on 3% of the top 10% of log cabins. Even though the Expert Score of this log cabin is 3 points lower than that of the average for 13′ x 9’s floored with a 12mm material (80 vs the average of 83), you can be sure it’s not due to the flooring because this one of the highest scoring flooring thicknesses available on 13′ x 9′ log cabins. 5% of 13′ x 9′ log cabins (8 in total) use 12mm thick floor boarding.

Window
Styrene windows come installed on this log cabin. As a glazing option, we rate it the worst out of the 4 glazing types found on 13′ x 9′ log cabins [14]. This particular type of glazing is used on 3% of all windowed log cabins with a look at the top 10% of log cabins showing us that none of them choose to install windows with this kind of glazing. 4% of 13′ x 9′ log cabins with windows (5 in total) use styrene windows, and when taking the average Expert Score of those styrene 13′ x 9′ log cabins (80), the Mercia 4 x 3m 19mm Log Cabin is the same with an Expert Score of 80.

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 log cabins that have options that you might find a better fit if this is a concern you have.

1. 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. ↩
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. ↩
