Exterior Plyboard for a garden workshop

[amatureleccy]

How big is this workshop?

It is 4.8m by 3m

All, thank you very much for your input on this - I have found it really helpful. I started this off in the Carpentry forum as the original question related to the use of plywood. I am desparate not to erect something that, given the environment where it will be installed, will have a limited life span. I want this to be a one-off build project. Given my age now, it will be a blessing if it lasts 30 years.

Hence the cement board being a very realistic option. The other option I am going to look at is the corrugated Onduline sheeting. Just trying to work out how I seal it at the top and bottom to stop rodent/insect ingress - the undulations are a perfect fit for any Rat.

I might continue the conversation over in the building section now that I have moved away from plywood.

Thanks all.

SIPs?

It is 4.8m by 3m

So < 15m²

Yes. And am only contemplating using cement board cladding for the unexposed sides - I will be doing treated redwood - T&G on the seen faces. I will be painting the board with some breathable masonary paint - but havent figured out what that is yet.

SIPs?

Sorry, as my name suggests, I am not in the trade - a simple amature with nothing but an adventurous spirit - what is SIPs.

@Captain Nemesis find me an estate built prior to 1995 (taking this as the point where asbestos products began to be phased out rapidly) and I may concede, however as you are being pedantic, in construction industry terms cement asbestos board was never referred to as cement fibre board. At least not in my lifetime. And the widespread use if cement fibre boards with treated wood fibre filler for tasks such as backer board in bathrooms, water proof and fire proof cladding on buildings really is relatively recent

Maybe you should try to assist the OP by answering their questions as opposed to trying to pick arguments

SIPs are structural insulated panels - and are relatively expensive compared to more conventional approaches. Basically two layers of ply or the like bonded to an insulation core. I built a house from them in the early 1990s - the biggest plus was that they are very fast to build with but AFAIK they need s concrete base to carry the track (although today I've been working in a build where solid laminated structural timber boards have simply been angle plated onto a concrete base using nothing more than angle plates)

If you go to YouTube, there is a channel on there called Oakwood garden buildings, he uses metal roofing sheets for the sides that face fences etc. He also explains how to rivet it for a neat finish.

I live near East Grinstead and ScandiaHus have their head office nearby, I've done some work for them.

They use SIPs for their house builds. It's an interesting method, but too expensive for small projects.

That's what I found out at the time. Another major disadvantage was that due to the size and weight of the panels we needed to crane on site

My current employer has also got a timber frame workshop where they prefabricate conventional timber frame houses. In comparison it's a bit like building big sheds...

Maybe you should look back at who it is who has been trying to pick an argument.

I like the look of the roof sheets as seen in the Oakwood video. I will have to figure out some way to seal the bottom and top to make them vermin proof.

Even though they have no exposure to the weather, being close to a fence, damp, rot, insects and rodents are a major consideration. Once erected, I will not be able to access the outside so low maintenance is a major consideration.

Dont the same concerns surrounding lack of access to the building arise from lack of access to the fence?

Behind my workshop is an old fence. On the other side the of fence - on my nieghbour's property, they too have a shed. So yes, the fence will suffer but it will never perform the role of a fence and I will never be inclined to maintain it.
