Silver vs Green. Which Colour Greenhouse Should I Buy?

Buying a greenhouse is not easy. We understand this. A great deal is rightly made out of the cost and stress in buying a house or maybe a car, or even car insurance but not a greenhouse?

Green and Silver Greenhouses

Okay, the cost of a greenhouse is not that of bricks and mortar, but it can still be a significant outlay, particularly if you are retired, and are living on a fixed income.

It could be several hundreds of pounds at least, but quite possibly several thousands of pounds as well. The cost is not just in money either as a greenhouse may be an investment in a lifestyle, or an economic purchase if you are hoping to grow food to help feed you and your family.

Whatever the reason, or cost, I want to help you make one decision based on knowledge rather than intuition: silver v green!

Aluminium Greenhouses, Stronger and Lighter

When aluminium became a viable alternative to wood as a construction material for greenhouses there was only one colour, and that was silver, or more precisely, milled aluminium. Aluminium is a relatively soft metal but has the massive benefit of being very light. Not only are packaging and transport costs reduced but the ease of handling becomes a lot more user-friendly. However, once exposed to the elements aluminium starts to weather down to a dull matt grey colour. And, more importantly, it also oxidises.

Mr. Topliss, my old chemistry teacher would know exactly what this means, and I probably should, but chemistry was not my strong point. The reality is a powdery, slightly unsightly bubbling on the surface of the aluminium during the process. Think Baking Powder bubbling on the surface.

Today this process can be significantly eradicated if the aluminium is anodised. This is a process that Vitavia greenhouses adopt as their default procedure. It is worth remembering this if you chose silver, as the extra cost is not significant, but the effect is.

Powder Coating Aluminium

Powder coating aluminium, with a colour, has been the popular alternative over the last 20 years. When Halls greenhouses first introduced a green powder coated greenhouse they decided that it should be called a Highgrove greenhouse, with a nod in the direction of Prince Charles, and all things pleasing to the eye. This was an upmarket product now, without a doubt.

The cost of powder coating is not insignificant, unfortunately. Each individual piece of metal has to go into an industrial ‘oven’ to be powder coated. The finish is then baked on to get the final matt lustre that we are now familiar with. As the powder coating encapsulates the aluminium there is no oxidising. All that is required is an annual brush down with a broom and some soapy water to get the greenhouse looking as good as new.

Quote: "Why do we send valuable items like aluminium and food waste to landfill when we can turn them into new cans and renewable energy? Why use more resources than we need to in manufacturing? We must now work together to build a zero waste nation" Hilary Benn - UK Member of Parliament

Halls and Elite Greenhouses

Halls greenhouses experimented further and trialled Aubergine and Lavender amongst other colours for their 6x4 Popular Greenhouse. These were designed to appeal to the ladies or those that literally wanted a splash of colour in the garden…. all year round.

Elite Greenhouses currently offer a range of different coloured powder coated options across their entire range. Buy your Belmont Greenhouse in green, black, white, terracotta, graphite, berry, stone, olive or brown. In fact, you can choose your own RAL colour if you wish (at an extra cost).

If you want further details about powder coating techniques Hane Paint & Powder Finishers of Stirling Road in Berkshire are a great place to start.

Powder coating comes at a cost, but it has significant advantages too. I would choose a powder coated building if it was going to be within sight of the house and easily viewed through the windows. If the greenhouse was tucked away out of sight I would probably choose silver.

However, my wife’s opinion may be completely different altogether…..?
