Hi all,
I’m really hoping someone can help me prevent potential condensation problems. Here are the details:
I have a single skin breeze block shed for woodworking (so plenty of tools that might rust).
Shed measures 6m x 5m.
The walls outside are rendered.
The roof is flat, made of fibreglass, sitting on top of OSB, on top of timber joists.
The joists measure 170mm deep
I’m placing 100mm thick Kingspan (TR26) insulation boards between the joists.
I only have one entry point, a standard sized door. There are no windows though I plan to put one in later on.
The walls of the shed are bare breezeblock with no insulation as of yet.
As far as I can tell, when the door is shut, there is no airflow inside the shed.
I’ve uploaded a drawing detailing how I will be doing the insulation. The Kingspan senior tech told me there needs to be at least a 50mm gap around the insulation board.
With the above set up, what is the best procedure to take to prevent condensation and moisture build up? If my tools start to rust, I'll cry.
In case it is important, the shed floor is concrete and has a Damp Proof Membrane to prevent rising damp.
My only idea is to cut rectangular holes in the fascia(?) and place vents over the holes. These holes would be at the exact same level as the space between the joints. Apart from the vents, I have no idea how to proceed.
I should add I'm very inexperienced in building/construction work.
Thanks all.
