I have aquired a large double garage of the above construction with my house.
- Frame is U and W shaped open pressings, with plastic coated corigated steel walls.
The main issue at the moment is ground water running through the garage which i hope to cure by laying a course of bricks around the perimeter just inside the cladding under the lower frame member (theres about 4inchs between this and the conreate slab) and then putting in a damp proof membraine and new floor.
However once done I would like to insulate to allow me to apply occational heat to take the chill off the air and tools iwhen im working in there in winter, but also to reduce noise transfer as the often the only time I get in there is evenings when any sound just goes straight through to outside, which backs onto other houses.
Its not a proiraty and I dont want to spend too much time and money on it, but more importantly dont want to overly compromise the life of the garage by trapping and retaining damp.
Thoughts so far are, damp proof membraine, followed by glass or rockwool, over laid with a second dpm and boarded. Which is proberbly the most sound absobing. Rigid closed cell board on the back of the boarding, with air gap between steel and insulation, not sure on costs here. Or have spray foam put in onto the steel, and board over, with air gap between foam and boarding.
Boarding would proberbly be exterior grade 10mm ply or simular as although PB would be more sound proof and can be bought pre-insulated there are durabilty issues both with damp and impact and it is far less easy to secure shelving to.
