My daughter has had a single storey lean-to extension built.
The roof has 4" insulation above the insulated plasterboard ceiling as per current building regs. The ceiling has 9 downlights which are supposed to be led, but she is not sure if they have installed thge right type. the electrician told my daughter's husband that prior to the ceiling being finished he should cut out the 4" insulation as a slot 4" wide between the rafters where each light goes to facilitate wiring and fixing the lights. He did this and the ceiling was plasterboarded and skimmed. The electrician cut circular holes for the downlights plus other holes adjacent to help fish the wires through. Now the lights are fixed and each one is dripping with water due to condensation because the lights are very cold and the room is heated; also a cold draught is coming through each light.
What can they do to overcome this problem, and what was the point in having a well insulated ceiling to cut it away in 9 places?
HELP!
