Our verdict on the 7m², 14x7FT polycarbonate greenhouse with base frame – Sapin – 2 skylights, gutter – Transparent
The 7m², 14x7FT polycarbonate greenhouse with base frame – Sapin – 2 skylights, gutter – Transparent fit with sliding doors and is treated using a galvanised process [1]. The 2 windows used on this particular 14′ x 7′ use a glazing material (Thickness was not specified).
Base material: aluminium [2]
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. A 4mm thick cladding like the one used on walls of this greenhouse is one of the best rated by our experts.
2. 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
Fantastic, 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 2 [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 15% of 14′ x 7′ greenhouses (5 in total [6]), and when taking the average Expert Score of those 14′ x 7′ greenhouses (90), the 7m², 14x7FT polycarbonate greenhouse with base frame – Sapin – 2 skylights, gutter – Transparent is the same with an Expert Score of 90.

Cladding
The aluminium cladding(walls) used here is an about average form of construction for walls and is the only type [7] we’ve identified on same-size greenhouses, that you’ll also see getting used on 23% (180 of 787) of all greenhouses analysed [8], as well as being used on 6% (5 of 78) of the top 10% of greenhouses [9]. You’ll also find the aluminium cladding showing up on 41% of 14′ x 7′ greenhouses (14 in total) [10], and if we compare this item against those 14 we find it’s Expert Score is 20% higher than the average score for a 14′ x 7′ aluminium greenhouse.
The walls are 4mm thick and we rate this the best thickness out of the 2 found on same-size greenhouses [11]. It is used on 1% of all greenhouses [12] and after analysing the top 78 products that make up the top 10% of greenhouses [13], we don’t find this thickness present on any of them. Further analysis shows us that out of all 14′ x 7′ greenhouses this is the only one to use 4mm thick walls [14].

Height
The height of this greenhouse is 1900mm (6′) which is 21% less than the average 14′ x 7′ greenhouse, giving you 390.0mm (1′) less headroom.

You Might Also Consider
We found 15 14′ x 7′ greenhouses with comparable specifications. The 7m², 14x7FT polycarbonate greenhouse with base frame – Sapin – 2 skylights, gutter – Transparent has an Expert Score that is 19% higher than average and is £147 less expensive than average. If you are looking for the best value or highest expert scoring greenhouses out of the 15 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 £306 with this Outsunny Walk-in Tunnel Greenhouse Gardening Planting Shed Heavy Duty Warm House. It is priced at £93, this is 329% less than this and has an Expert Score of 87, 2 points less than the 7m², 14x7FT polycarbonate greenhouse with base frame – Sapin – 2 skylights, gutter – Transparent.
Highest Expert Score – With an Expert Score of 92 vs 90 for this product, the Outsunny 8x12ft Polycarbonate Walk-in Greenhouse Outdoor w/ Double Sliding Door is the best 14′ x 7′ greenhouse with comparable specifications, and is priced at £788, that’s £389 more than the 7m², 14x7FT polycarbonate greenhouse with base frame – Sapin – 2 skylights, gutter – Transparent.
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 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. Aluminium: Is a very stable metal that has very low corrosion rates in neutral environments (such as domestic garden buildings). The good corrosion resistance of aluminium alloys means that they are perfectly suited for outdoor and industrial environments. This resistance is caused because aluminium is a very reactive metal with a high affinity for oxygen, The reactive character of the aluminium with oxygen means an aluminium oxide film forms on the metal surface that gives it a protective character.
The most common type of aluminium alloys used for architectural structures (such as garden buildings) is the 6XXX Aluminium-magnesium-silicon.
The Aluminium Federation in the article UK Aluminium Industry Fact Sheet 2, Aluminium and Corrosion say “The 6XXX series alloys are the most common amongst aluminium alloys and are widely used in transport, engineering and architecture.” They then go on to say “Most aluminium casting alloys are classified as having good corrosion resistance, and if used for purposes involving exposure out-of-doors, they will suffer no appreciable loss of strength as a result of corrosion. Weathering tests lasting more than ten years, carried out by The Association of Light Alloy Refiners, confirm that there is little difference in the resistance to atmospheric attack of the casting alloys…” ↩
