Cladding

Great, our experts say most of the cladding options used are among the best.

The shiplap tongue & groove cladding(walls) used here is one of the best forms of construction for shed walls out of the 4 types [2] we’ve identified on same-size sheds, that you’ll also see getting used on 31% (1,373 of 4,360) of all sheds analysed [3], as well as being used on 42% (185 of 436) of the top 10% of sheds [4]. Even though the Expert Score of this particular shed is 1 point below that of the average shiplap tongue & groove clad 3′ x 11’s (they have an average Expert Score of 91), with it being on 42% of the top 10%, its use here is a reassuring sign of a high quality cladding. You’ll also find the shiplap tongue & groove cladding showing up on 33% of 3′ x 11′ sheds (153 in total) [5].

The walls are 12mm thick and we rate this the best thickness out of the 11 found on same-size sheds [6]. It is used on 54% of all sheds [7] and is also used across 58% of the top 10% of sheds [8] we analysed. Even though the Expert Score of this particular shed is 1 point below the average 12mm clad 3′ x 11’s score of 91, the fact that 58% of the top 10% use a cladding this thick is reassuring as a sign of quality. 61% of 3′ x 11′ sheds (285 in total) use 12mm thick walls [9].

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 [10]. 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 3 points below the average of 93 for 3′ x 11’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. 31% of 3′ x 11′ sheds (146 in total) use tongue & groove construction for the roof.

A 12mm thick roof boarding was used on this shed which is one of the best thicknesses used for a roofing material out of 12 thicknesses identified on same-size sheds [11]. It’s used on 29% of all sheds and 48% of the top 10% of sheds. Even though the Expert Score of this particular shed is 2 points below that of the average for 3′ x 11’s that use 12mm roofing (90 vs the average of 92), with it being on 48% of the top 10%, this should give you confidence in its quality. 28% of 3′ x 11′ sheds (129 in total) use a 12mm thick roof boarding.

Heavy duty mineral felt is used as the roof covering, and out of 3 types identified on same-size sheds [12], is said to be the best roof covering material. It comes fitted on 1% of sheds and used on 1% of the top 10% of 3′ x 11′ sheds. 2% of 3′ x 11′ sheds (9 in total) make use of a heavy duty mineral felt material as a roof covering, and when taking the average Expert Score of those 3′ x 11′ sheds (90), the Redlands 4′ x 12′ Double Door Shiplap Modular Pent Security Shed is the same with an Expert Score of 90.

Best value – If you are looking for something comparable that costs less, then you could save £355 with this Redlands 6′ x 6′ Shiplap Modular Apex Bike Shed. It is priced at £559, this is 64% less than this and has an Expert Score of 100, 10 points higher than the Redlands 4′ x 12′ Double Door Shiplap Modular Pent Security Shed.

Highest Expert Score – With an Expert Score of 100 vs 90 for this product, the Redlands 6′ x 8′ Shiplap Modular Pent Bike Shed is the best 3′ x 11′ shed with comparable specifications, and is priced at £674, that’s £240 less than the Redlands 4′ x 12′ Double Door Shiplap Modular Pent Security Shed.

High Wind Area – If you live in a particularly exposed or high wind area then having a shed with a thicker cladding and higher than average frame thickness can be preferable. We found at least 3 sheds that have a combination of features that can make them more suited to higher wind areas.

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.

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.
