Our verdict on the Adley 4′ x 2 Mini Greenhouse

The Adley 4′ x 2 Mini Greenhouse comes with a pent style roof; holds a 10 Years guarantee; fit with double doors; is treated using a dip treated process [1]; and makes use of made in the uk, certified sustainable materials. The windows window used on this particular 3′ x 2′ use a styrene [2] glazing material (Thickness was not specified).

Base material: timber

Our experts say this has 1 stand out feature. 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 greenhouse is one the best available for greenhouses rated by our experts.

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

Cladding

The shiplap tongue & groove cladding(walls) used here is one of the best forms of construction for greenhouse walls out of the 3 types [3] we’ve identified on same-size greenhouses, that you’ll also see getting used on 4% (32 of 787) of all greenhouses analysed [4], as well as being used on 5% (4 of 78) of the top 10% of greenhouses [5]. You’ll also find the shiplap tongue & groove cladding showing up on 7% of 3′ x 2′ greenhouses (2 in total) [6], and when taking the average Expert Score of those 3′ x 2′ greenhouses (95), the Adley 4′ x 2 Mini Greenhouse is the same with an Expert Score of 95.

The walls are 12mm thick and we rate this an about average thickness out of the 2 found on same-size greenhouses [7]. It is used on 5% of all greenhouses [8] and is also used across 13% of the top 10% of greenhouses [9] we analysed. 7% of 3′ x 2′ greenhouses (2 in total) use 12mm thick walls [10], and when taking the average Expert Score of those 3′ x 2′ greenhouses (95), the Adley 4′ x 2 Mini Greenhouse is the same with an Expert Score of 95.

Roofing

Styrene is the material used for the roofing, our experts rate this one of the worst forms of roof material out of the 2 types we’ve found on same-size greenhouses [11]. This roofing material is used on 1% of all greenhouses analysed, and 4% of the top 10% of greenhouses. Out of all 3′ x 2′ greenhouses we find this is actually the only one to use a styrene roofing.

Window

Styrene windows come installed on this greenhouse. As a glazing option, we rate it the worst out of the 2 glazing types found on 3′ x 2′ greenhouses [12]. This particular type of glazing is used on 9% of all windowed greenhouses and 12% of the top 10% of greenhouses with windows we analysed. Out of all windowed 3′ x 2′ greenhouses this is the only greenhouse to make use of styrene windows.

You Might Also Consider

We found 14 3′ x 2′ greenhouses with comparable specifications. The Adley 4′ x 2 Mini Greenhouse has an Expert Score that is 22% higher than average and is £26 less expensive than average. If you are looking for the best value or highest expert scoring greenhouses out of the 14 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 £194 with this Wilko Wooden Cold Frame Greenhouse. It is priced at £25, this is 776% less than this and has an Expert Score of 75, 20 points less than the Adley 4′ x 2 Mini Greenhouse.

The Adley 4′ x 2 Mini Greenhouse is the best scoring greenhouse available out of all 14 3′ x 2′ greenhouses we analysed.

High Wind Area – If you live in a particularly exposed or high wind area then having a greenhouse with a thicker cladding and higher than average frame thickness can be preferable. We found at least 2 greenhouses 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 greenhouses 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 1 greenhouses 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 2 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.
