This week we have three or maybe four main areas of questions.  We’ve had quite a few enquiries about roof insulation this week.  We have a load of enquiries about a floor construction without using concrete.  We’ve got enquiries about fixing fixtures and fittings to walls after they’ve been insulated and then we’ve got a load of questions about render and what they can be applied to, how you care for them, how long it takes to dry and how you clean them.
