1. The mineral felt roof covering found on this summer house is rated to be one of the best by our experts.

2. A floor that is 14mm thick is something our experts say is one of the best available for this kind of summer house.

3. A pressure treated treatment like the one used on this summer house 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 summer house fairs across the market.

Cladding

The overlap board cladding(walls) used here is the worst form of construction for summer house walls out of the 2 types [2] we’ve identified on same-size summer houses, that you’ll also see getting used on 4% (29 of 741) of all summer houses analysed [3], and sadly not present at all on any of the 74 summer houses that make up the top 10% of summer houses [4]. In fact this is the only 8′ x 12′ summer house you’ll find that uses an overlap board wall [5].

The walls are 7mm thick and we rate this the worst thickness out of the 3 found on same-size summer houses [6]. It is used on 2% of all summer houses [7] and after analysing the top 74 products that make up the top 10% of summer houses [8], we don’t find this thickness present on any of them. Further analysis shows us that out of all 8′ x 12′ summer houses this is the only one to use 7mm thick walls [9].

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 2 types we’ve found on same-size summer houses [10]. This roofing material is used on 5% of all summer houses analysed, and 1% of the top 10% of summer houses. 2% of 8′ x 12′ summer houses (2 in total) use osb construction for the roof, and when taking the average Expert Score of those 8′ x 12′ summer houses (73), the 8′ x 12′ Forest Oakley Double Door Apex Summer House is just above the average with an Expert Score of 75.

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 [11]. It’s used on 2% of all summer houses and 1% of the top 10% of summer houses. Our data on all 8′ x 12′ summer houses shows us this is the only one to use a 8.0mm 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 [12]. It comes fitted on 26% of summer houses and used on 43% of the top 10% of 8′ x 12′ summer houses. Even though the Expert Score of this particular summer house is below the average 8′ x 12’s cover their roofs with mineral felt (75 vs the average of 78), with it being on 43% of the top 10%, this should give you confidence in its quality. 17% of 8′ x 12′ summer houses (23 in total) make use of a mineral felt material as a roof covering.

It’s found on 2% of all summer houses with none of the 74 summer houses that make up the top 10% using a floor of this thickness.

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 summer houses 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.
