Thread: Shed insulation |
24/10/2009 21:11:50 |
Hi My workshop is double skinned with two inches of loft insulation in the walls and 4 inches in the loft,with a concrete floor ,the concrete was laid on a polythene membrane to stop damp,on top of the concrete a sheet of poly thene was laid with two layers of 16mm chip board on top, the windows are double glazed ,i used glazing units whose seal had started to leak but were free. the work shop does not immediately go to the outside there is anothe part of the shed for dirty work,grinding etc so the door to my workshop is several feet from the outside atmosphere,The workshop is only heated when I am using it, but i do not get any condensation or rust,the outer dirty workshop is not insulated .I have another workshop where the floor is insulated by kingspan type insulation which is suitable for installation under concrete floors in modern housing and is capable of supporting high loads if a floor oh 16 mm ply is laid over the insulation,I t is important to insulate the floor cold and damp rise,certain heavy machine tools may not sit too well on insulation so cut a hole in the floors and insert hard wood blocks.for walls and ceiling use good quality insulation which has a fire rating,some cheaper insulation is not too fire retardent. inner walls should be 16 mm ply heavy but is difficult get through and should deter thieves.With insulated sheds block up all holes no matter how small to keep out mice and vermin,they love insulated ceilings .If a electric cable has to pass through a double shed wall, case the cable in a short length of stee tube again to prevent mice attacks, mice and electrics cause fires. by the way two layers of chipboard laid over concrete will support a Colchester master and 30 cwt of mill without affecting performance or precision. |
