Below is a brief overview of how some of the key points of this log cabin fairs across the market.
Cladding
Amazing, our experts say most of the cladding options used are among the best.
The interlocking log cladding(walls) used here is the best 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 72% (639 of 893) of all log cabins analysed [4], as well as being used on 98% (87 of 89) of the top 10% of log cabins [5]. You’ll also find the interlocking log cladding showing up on 81% of 20′ x 11′ log cabins (73 in total) [6], and when taking the average Expert Score of those 20′ x 11′ log cabins (86), the Forest Arley 6m x 3m Log Cabin is just above the average with an Expert Score of 90.
The walls are 45mm thick and we rate this the best thickness out of the 8 found on same-size log cabins [7]. It is used on 3% of all log cabins [8] and is also used across 2% of the top 10% of log cabins [9] we analysed. While you’ll find that the Expert Score of this log cabin is 2 points lower than the average for 20′ x 11’s that use 45mm thick cladding (90 vs the average of 92) [10], you can be sure it’s not due to the cladding thickness as this one of the highest scoring thicknesses available on 20′ x 11′ log cabins. 7% of 20′ x 11′ log cabins (6 in total) use 45mm thick walls.

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 log cabins [11]. This roofing material is used on 64% of all log cabins analysed, and 100% of the top 10% of log cabins. 82% of 20′ x 11′ log cabins (74 in total) use tongue & groove construction for the roof, and when taking the average Expert Score of those 20′ x 11′ log cabins (86), the Forest Arley 6m x 3m Log Cabin is just above the average with an Expert Score of 90.
A 19.0mm thick roof boarding was used on this log cabin which is the best thickness used for a roofing material out of 4 thicknesses identified on same-size log cabins [12]. It’s used on 7% of all log cabins and 20% of the top 10% of log cabins. 18% of 20′ x 11′ log cabins (16 in total) use a 19.0mm thick roof boarding, with this product having an Expert Score 5% higher than average.

While the Expert Score of the average polyester felt covered 20′ x 11′ log cabin is 2 points higher than this item (90 vs the average of 92), you can be sure it’s not the roof covering bring the score down as this one of the highest scoring roof coverings found on 20′ x 11′ log cabins. 7% of 20′ x 11′ log cabins (6 in total) make use of a polyester felt material as a roof covering.

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 log cabins that have a combination of features that can make them more suited to higher wind areas.

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. Pressure Treated: Considered the most durable wood treatment, this is where the wood undergoes a process called tanalisation. This is where the timber is submerged in specialist wood preservatives (such as Tanalith E, this is actually the origin of the word ‘tanalisation’), this is a unique combination of copper and organic biocide ingredients (it is the copper that gives the finished wood the slightly green colour). The wood then goes into a high pressure vacuum tank (the Wood Protection Association has a good article/video on this) 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 BS 8417 code of practice (this advises on the choice of timber species and the use and application of wood preservatives) says “ penetration to either 6 mm (15 years) or 12mm (for 30 years) has to be achieved in any exposed surface in sawn material.”
It is also worth noting that if cross cutting, notching or boring treated timber during or after installation, ALWAYS apply an end grain solvent-based (or oil-based) wood preservative treatment to the freshly exposed areas, this will maintain the integrity of the protection. NEVER put cut ends in the ground, even if end grain coated. ↩
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. ↩
