Our verdict on the Greenhouse 4.5m虏 300x150x200 cm32394-Serial number

The Greenhouse 4.5m虏 300x150x200 cm32394-Serial number is treated using a galvanised process [1]. The 2 windows used on this particular 9′ x 4′ use a glazing material (Thickness was not specified).

Base material: steel [2]

Our experts say this has 3 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 construction like the one used on the roof of this greenhouse is rated one of the best by our panel of experts.

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

3. A galvanised 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.

Treatment

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

The galvanised treatment process used here is the best type of treatment out of 4 [3] types we’ve identified on same-size greenhouses that you’ll see getting used on 17% [4] (137 of 787) of all greenhouses analysed, as well as being used on 23% [5] (18 of 78) of the top 10% of greenhouses. You’ll also find the galvanised treatment showing up on 21% of 9′ x 4′ greenhouses (15 in total [6]), and if we compare this item against those 15 we find it’s Expert Score is 5% higher than the average score for a 9′ x 4′ galvanised greenhouse.

Cladding

The steel cladding(walls) used here is an about average form of construction for greenhouse walls out of the 2 types [7] we’ve identified on same-size greenhouses, that you’ll also see getting used on 19% (152 of 787) of all greenhouses analysed [8], as well as being used on 1% (1 of 78) of the top 10% of greenhouses [9]. You’ll also find the steel cladding showing up on 17% of 9′ x 4′ greenhouses (12 in total) [10], and if we compare this item against those 12 we find it’s Expert Score is 12% higher than the average score for a 9′ x 4′ steel greenhouse.

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 greenhouses [11]. This roofing material is used on 4% of all greenhouses analysed, and 3% of the top 10% of greenhouses. While you’ll find that the Expert Score of this greenhouse is 4 points lower than the average for 9′ x 4’s that use tongue & groove roof material (77 vs the average of 81), you can be sure it’s not due to the roofing as this one of the highest scoring materials found on 9′ x 4′ greenhouses. 3% of 9′ x 4′ greenhouses (2 in total) use tongue & groove construction for the roof.

A 12mm thick roof boarding was used on this greenhouse which is one of the best thicknesses used for a roofing material out of 2 thicknesses identified on same-size greenhouses [12]. It’s used on 4% of all greenhouses and 3% of the top 10% of greenhouses. Even though the Expert Score of this particular greenhouse is 4 points below that of the average for 9′ x 4’s that use 12mm roofing (77 vs the average of 81), you can be sure it’s not due to the roof thickness as this one of the highest scoring thicknesses available on 9′ x 4′ greenhouses. 3% of 9′ x 4′ greenhouses (2 in total) use a 12mm thick roof boarding.

Flooring

The manufactures of this greenhouse chose tongue & groove for the floor construction, we rate this the best form of floor construction and is the only type found on this size of greenhouse [13]. This type of floor construction is used on 4% of all greenhouses we analysed, and 3% of the top 10% of those greenhouses. Even though the Expert Score of this greenhouse is 4 points lower than that of the average for 9′ x 4’s floored with a tongue & groove material (77 vs the average of 81), you can be sure it’s not due to the flooring because this one of the highest scoring flooring materials available on 9′ x 4′ greenhouses. 3% of 9′ x 4′ greenhouses (2 in total) use tongue & groove 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 greenhouses [14]. It’s found on 4% of all greenhouses and used on 3% of the top 10% of greenhouses. Even though the Expert Score of this greenhouse is 4 points lower than that of the average for 9′ x 4’s floored with a 12mm material (77 vs the average of 81), you can be sure it’s not due to the flooring because this one of the highest scoring flooring thicknesses available on 9′ x 4′ greenhouses. 3% of 9′ x 4′ greenhouses (2 in total) use 12mm thick floor boarding.

It is priced at £75, this is 2992% less than this and has an Expert Score of 60, 17 points less than the Greenhouse 4.5m虏 300x150x200 cm32394-Serial number.

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.

Marlborough Greenhouses 6′ x 6′ Wooden Greenhouse with 4 windows

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 3 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. Galvanised: Galvanising steel or Zinc Galvanised steel as it is sometimes called refers to the process where steel is immersed into molten zinc. This is where a series of zinc-iron alloy forms a series layers via a metallurgical reaction between the iron and zinc, providing a robust coating which is an integral part of the steel.

Galvanised steel is among the most corrosion resistant due to its sacrificial protection and self-repairing properties. According to the Galvanizers Association they say “Hot dip galvanising offers coverage both externally and internally within hollow sections, it self-repairs when damaged, sacrifices itself to protect the base metal, is environmentally sustainable, has good impact and abrasion-resistance and a maintenance-free life of 50 years or more. Galvanised steel is widely used in applications where corrosion protection is needed and can be identified by the crystallised pattern on the surface (often called a ‘spangle’).” 

2. Steel: Is the “world’s most important engineering and construction material” according to the World Steel Accosiation. When it comes to garden structure steel is often a very strong and durable metal, although if it is untreated then it is prone to rust and corrosion. Steel is an alloy of iron mixed with less than 2% carbon and 1% manganese and small amounts of silicon, phosphorus, sulphur and oxygen. When steel comes into contact with water and oxygen there is a chemical reaction and the steel begins to revert to its original form – iron oxide (that’s Rust to the layperson). Steel must be coated in a protective layer to stop this reaction, for most garden applications this consists of powder coating or the more stable and long lasting use of galvanising the steel first.
