Vcl or not

[James1]

Hi all. 

Whats your thoughts on a vcl being fitted to a detached garage/workshop plus bonus/games room in attic truss space. Garage will be timber frame with cladding. I will insulate walls and ceilengs but not sure if i should put a vcl in as well. I can see it just getting used at weekends ect and only heated some of the time. My thinking is that periods of no use/heat will actually cause condensation if i DO fit a vcl as the inside temp could be colder than outside through the day.

Yes, VCL. You can run a condensation risk analysis if you are nervous about it. It may be that at some times of the day and year in some conditions there is a condensation risk but I doubt this will be serious.
