Attic Insulation Inspection

Attic Insulation Inspection Montreal

MTL Attic Inspection Montreal. Attic is defined as the space enclosed by the building wall and is directly below the roof. As this is an area not occupied continuously by anybody.

(Except in special designs and home modifications) it is unheated. Some components of utilities such as water heaters, hot water storage, air conditioning, heating air ducts and goods storage may be located here depending on the volume of space available. The roof and the floor are insulated though often inadequately.

Modern building codes permit both vented and invented attics in all climates, if a building is otherwise correctly constructed. However, unoccupied attics should usually be ventilated to reduce the accumulation of heat and moisture that contribute to mold growth and decay of wood rafters and ceiling joists. In cold climates ventilation also helps to prevent ice-dams on the roof and leaks that they cause. In hot climates, ventilation reduces cooling loads. Call us now for more details
