Can I get some advice from those of you that have layouts in their lofts?
I have a large layout (just track & stock only atm) in my loft which is a modern truss roof with a layer of black cloth type material between the roof spars and the tiles on the outside.
My problem is probably a common one: Temperature.
In the winter with a small electric heater and an open hatch I can keep temperatures to above 5c at worst overnight and make them habitable during the day. It's during summer I have the problems. Temperatures will reach 40c up there on the warmest days and I am concerned about long term damage to stock and buckling of track, not to say it is totally impossible to work up there at those sorts of temps.
My options seem to be1) Roof light to let heat out. Expensive and may not work well enough to be worth the outlay. 2) Portable A/C unit but the cheaper ones need good ventilation which I obviously don't have. 3) Some sort of insulation in the roof between the trusses to keep the temps down in summer and up in winter. Again, expensive and not a DIY option as far as I know. One loft extension company warned me that the material has to be a special sort to prevent the roof sweating.
I can't see any other options but has anybody else had my problem and actually solved it? I don't mind throwing a bit of money at it for a workable solution.
