Our verdict on the 3’9 x 1’6 Forest Georgian Tall Wall Lean to Greenhouse with Auto Vent
The 3’9 x 1’6 Forest Georgian Tall Wall Lean to Greenhouse with Auto Vent comes with an apex style roof, holds a 15 Years guarantee, is fit with lockable single doors that use a latch locking system, is treated using a pressure treated process [1], and makes use of certified sustainable materials. The 20 windows used on this particular 4′ x 2′ use a 2mm styrene [2] material.
Base material: wood
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 tongue & groove cladding used on this greenhouse is one the best available for greenhouses rated by our experts.
2. A pressure treated treatment like the one used on this greenhouse 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 greenhouse fairs across the market.
Cladding
The tongue & groove cladding(walls) used here is the best form of construction for greenhouse walls out of the 2 types [3] we’ve identified on same-size greenhouses, that you’ll also see getting used on 5% (40 of 787) of all greenhouses analysed [4], as well as being used on 12% (9 of 78) of the top 10% of greenhouses [5]. While you’ll find that the Expert Score of this greenhouse is 12 points lower than the average for tongue & groove clad 4′ x 2’s (75 vs the average of 87) [6], you can be sure it’s not due to the cladding as this one of the highest scoring materials found on 4′ x 2′ greenhouses. You’ll also find the tongue & groove cladding showing up on 7% of 4′ x 2′ greenhouses (2 in total).
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 4′ x 2′ greenhouses (2 in total) use 12mm thick walls [10].

Roofing
Styrene is used as the roof covering. Our experts say it’s an about average roof covering material, and is also the only kind identified on same-size greenhouses [11]. It comes fitted on 2% of greenhouses and used on 1% of the top 10% of 4′ x 2′ greenhouses. 7% of 4′ x 2′ greenhouses (2 in total) make use of a styrene material as a roof covering.

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 4′ 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. 17% of 4′ x 2′ greenhouses with windows (2 in total) use styrene windows.
The windows on this greenhouse use a 2mm thick glazing, we rate this one of the worst thicknesses for window glazing. You’ll also find this is the only thickness glazing used on same-size greenhouses [13]. Glazing this thick is found on 1% of all the windowed greenhouses we analysed and used on 2% of the top 10% of windowed greenhouses. Out of all windowed 4′ x 2′ greenhouses this is the only greenhouse to make use of 2mm windows.

Height
The height of this greenhouse is 2020mm (7′) which is 11% more than the average 4′ x 2′ greenhouse, giving you 197.0mm (0.6′) extra headroom.

Doors
The door height is 1,410.00mm (5′) tall, which after analysing all 4′ x 2′ greenhouses, matches the average exactly.
The door width is 420.00mm (1′) wide which is 27% or 112.00mm (0.4′) narrower than the average 4′ x 2′.

We found 3 4′ x 2′ greenhouses with comparable specifications. The 3’9 x 1’6 Forest Georgian Tall Wall Lean to Greenhouse with Auto Vent has an Expert Score that is 13% lower than average and is £10 less expensive than average. If you are looking for the best value or highest expert scoring greenhouses out of the 3 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 £35 with this Mercia Mini Greenhouse. It is priced at £395, this is 9% less than this and has an Expert Score of 80, 5 points higher than the 3’9 x 1’6 Forest Georgian Tall Wall Lean to Greenhouse with Auto Vent.
Highest Expert Score – With an Expert Score of 100 vs 75 for this product, the Hartwood 5′ x 2′ Victorian Tall Wall Greenhouse with Auto Vent is the best 4′ x 2′ greenhouse with comparable specifications, and is priced at £589, that’s £159 more than the 3’9 x 1’6 Forest Georgian Tall Wall Lean to Greenhouse with Auto Vent.
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 3 other options that will fill those needs.

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. ↩
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. ↩
