I have a barn that I am planning to create an office/workshop in. It doesnt need to be in the lap of luxury but I would like it to be relatively warm and dry.
The barn seems fairly well sealled as things are. There are no damp patches even on/after the wettest days.
I have chipped off the internal limey cement, sprayed the wall with a Unibond mix and pointed the stone with cement and unibond.
I am now planning to put a wooden floor in, this will probably just be chipboard on joists.
I know I need to put down a damp proof membrane but was wondering about the best configuration for ventillation and insulation.
The walls are about 1 foot thick but there is one block section that I can fit a vent on to and was hoping to criss cross joists to allow the air to get in at all the wood.
What then is the best way to insulate this?
I was hoping to put fibreglass insulation under the chipboard but will this stop the air flow and increase the likley hood of dry rot in the future?
If the fibreglass is below the level of the vent will i loose any heat retention through the vent.
If anyone has come across this in the past I would be very greatful to hear your experiences.
