Study Notes

Roof Structure and Insulation

Roof structure requires more thermal insulation than wall or floor structures.
Thermal insulation controls the heat flow through the exterior assemblies of a building.

Corrugated Metal Roofing

Corrugated metal roofing provides protection against rainwater.

Moisture Protection

Vapour retarder is a component of moisture protection.
Joint sealants are used in moisture protection.

Insulating Materials

Masonry cavity walls use insulating materials.
Reflective insulation uses foil-backed gypsum boards.

Roof Deck

Corrugated metal can serve as a structural roof deck.

Matching Components

Thermal protection component: controls heat flow through exterior assemblies.
Moisture protection component: vapour retarder.
Insulating material: reflective insulation (uses foil-backed gypsum boards).
Roofing component: corrugated metal roofing (provides protection against rainwater).
Type of roof deck: corrugated metal (can serve as a structural roof deck).
