Our experts say this has 4 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 cladding used on this shed is one the best available for sheds rated by our experts.

2. The tongue & groove construction like the one used on the roof of this shed is rated one of the best by our panel of experts.

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

4. Our experts say this the tongue & groove floor material used here is one of the best available on all sheds.

Below is a brief overview of how some of the key points of this shed fairs across the market.

Cladding

The tongue & groove cladding(walls) used here is the best 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 35% (1,543 of 4,360) of all sheds analysed [4], as well as being used on 21% (92 of 436) of the top 10% of sheds [5]. While you’ll find that the Expert Score of this shed is 10 points lower than the average for tongue & groove clad 8′ x 4’s (80 vs the average of 90) [6], you can be sure it’s not due to the cladding as this one of the highest scoring materials found on 8′ x 4′ sheds. You’ll also find the tongue & groove cladding showing up on 39% of 8′ x 4′ sheds (136 in total).

Roofing

Tongue & groove is the cladding used for the roofing, our experts rate this the best form of roof material out of the 3 types we’ve found on same-size sheds [7]. This roofing material is used on 34% of all sheds analysed, and 57% of the top 10% of sheds. Even though the Expert Score of this particular shed is 13 points below the average of 93 for 8′ x 4’s using a tongue & groove roofing, with it being on 57% of the top 10%, you can be assured that this is a quality roof material. 34% of 8′ x 4′ sheds (120 in total) use tongue & groove construction for the roof.

A 12.0mm thick roof boarding was used on this shed which is one of the best thicknesses used for a roofing material out of 11 thicknesses identified on same-size sheds [8]. It’s used on 3% of all sheds and 5% of the top 10% of sheds. Even though the Expert Score of this particular shed is 10 points below that of the average for 8′ x 4’s that use 12.0mm roofing (80 vs the average of 90), you can be sure it’s not due to the roof thickness as this one of the highest scoring thicknesses available on 8′ x 4′ sheds. 2% of 8′ x 4′ sheds (6 in total) use a 12.0mm thick roof boarding.

Mineral felt is used as the roof covering, and out of 3 types identified on same-size sheds [9], 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 8′ x 4′ sheds. Even though the Expert Score of this particular shed is below the average 8′ x 4’s cover their roofs with mineral felt (80 vs the average of 89), with it being on 49% of the top 10%, this should give you confidence in its quality. 35% of 8′ x 4′ sheds (122 in total) make use of a mineral felt material as a roof covering.

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.

More Child Friendly – If you have children and you are looking for something that has that little extra in terms of durability then tougher glazing options might be a better option. Here we have at least 3 other options that will fill those needs.

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.
