Our experts say this has 2 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 mineral felt roof covering found on this shed is rated to be one of the best by our experts.
2. A pressure treated treatment like the one used on this shed is one our experts are happy to say is one of the best around.
Below is a brief overview of how some of the key points of this shed fairs across the market.
Cladding
The overlap board cladding(walls) used here is the worst form of construction for shed walls out of the 4 types [3] we’ve identified on same-size sheds, that you’ll also see getting used on 8% (357 of 4,360) of all sheds analysed [4], as well as being used on 3% (12 of 436) of the top 10% of sheds [5]. You’ll also find the overlap board cladding showing up on 19% of 4′ x 6′ sheds (69 in total) [6], and when taking the average Expert Score of those 4′ x 6′ sheds (81), the Rowlinson 4′ x 6′ Pressure Treated Overlap Apex Shed is just above the average with an Expert Score of 82.
The walls are 8mm thick and we rate this an about average thickness out of the 12 found on same-size sheds [7]. It is used on 1% of all sheds [8] and is also used across 1% of the top 10% of sheds [9] we analysed. 1% of 4′ x 6′ sheds (4 in total) use 8mm thick walls [10], and when taking the average Expert Score of those 4′ x 6′ sheds (80), the Rowlinson 4′ x 6′ Pressure Treated Overlap Apex Shed is just above the average with an Expert Score of 82.

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 sheds [11]. This roofing material is used on 18% of all sheds analysed, and 8% of the top 10% of sheds. While you’ll find that the Expert Score of this shed is 9 points lower than the average for 4′ x 6’s that use osb roof material (82 vs the average of 91), you can be sure it’s not due to the roofing as this one of the highest scoring materials found on 4′ x 6′ sheds. 19% of 4′ x 6′ sheds (70 in total) use osb construction for the roof.
Mineral felt is used as the roof covering, and out of 3 types identified on same-size sheds [12], 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 4′ x 6′ sheds. Even though the Expert Score of this particular shed is below the average 4′ x 6’s cover their roofs with mineral felt (82 vs the average of 89), with it being on 49% of the top 10%, this should give you confidence in its quality. 26% of 4′ x 6′ sheds (96 in total) make use of a mineral 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 sheds 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 sheds 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. 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. ↩
