Our verdict on the 6 x 4m Insulated Garden Room

The 6 x 4m Insulated Garden Room comes with a pent style roof, holds a 10 Years guarantee, and fit with double doors.

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 shiplap tongue & groove cladding used on this shed is one the best available for sheds rated by our experts.

2. A 72mm thick cladding like the one used on walls of this shed is one of the best rated by our experts.

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

Cladding

Fantastic, 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 walls and is the only type [1] 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 [2], as well as being used on 42% (185 of 436) of the top 10% of sheds [3]. Even though the Expert Score of this particular shed is 9 points below that of the average shiplap tongue & groove clad 20′ x 12’s (they have an average Expert Score of 84), 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 51% of 20′ x 12′ sheds (58 in total) [4].

The walls are 72mm thick and we rate this the best thickness and is the only thickness found on same-size sheds [5]. It is used on 1% of all sheds [6] and after analysing the top 436 products that make up the top 10% of sheds [7], we don’t find this thickness present on any of them. Further analysis shows us that out of all 20′ x 12′ sheds this is the only one to use 72mm thick walls [8].

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 sheds [9]. 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 10 points lower than the average for 20′ x 12’s that use osb roof material (75 vs the average of 85), you can be sure it’s not due to the roofing as this one of the highest scoring materials found on 20′ x 12′ sheds. 10% of 20′ x 12′ sheds (11 in total) use osb 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 2 thicknesses identified on same-size sheds [10]. 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 11 points below that of the average for 20′ x 12’s that use 12mm roofing (75 vs the average of 86), with it being on 48% of the top 10%, this should give you confidence in its quality. 70% of 20′ x 12′ sheds (80 in total) use a 12mm thick roof boarding.

Flooring

The manufactures of this shed chose osb for the floor construction, we rate this an about average form of floor construction and is the only type found on this size of shed [11]. This type of floor construction is used on 20% of all sheds we analysed, and 5% of the top 10% of those sheds. 17% of 20′ x 12′ sheds (19 in total) use osb construction for the floor.

A 12mm thick floor boarding is used here, this is one of the best floor board thicknesses according to our experts out of 2 found on same-size sheds [12]. It’s found on 31% of all sheds and used on 54% of the top 10% of sheds. Even though the Expert Score of this particular shed is below the average 20′ x 12’s that use 12mm flooring (75 vs the average of 86), with it being on 54% of the top 10%, this should give you confidence in its quality. 62% of 20′ x 12′ sheds (71 in total) use 12mm thick floor boarding.

You Might Also Consider

If you are looking for the best value or highest expert scoring sheds out of the 114 with comparable specifications the following might be of interest.

Best value – If you are looking for something comparable that costs less, then you could save £12,736 with this 15 x 16 WINDOWLESS Reverse Premier Pressure Treated Tongue And Groove Apex Shed With Higher Eaves And Ridge Height Double Doors + SUPER STRENGTH FRAM. It is priced at £264, this is 4831% less than this and has an Expert Score of 97, 22 points higher than the 6 x 4m Insulated Garden Room.

Highest Expert Score – With an Expert Score of 97 vs 75 for this product, the 10′ x 23′ Lotus Double Door Workshop Athracite Grey is the best 20′ x 12′ shed with comparable specifications, and is priced at £1,899, that’s £11,101 less than the 6 x 4m Insulated Garden Room.

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.
