Explain how the choice of enclosure materials for a building can affect construction costs and ongoing maintenance and repair costs.
What will be an ideal response?
Enclosures are built from many materials, including solid and composite wood, metal, cement, gypsum, plastic, and glass. The materials are chosen for their appearance, cost, and availability, as well as for their physical, mechanical, electrical, magnetic, thermal, optical, and acoustic properties. Degradation of enclosure materials due to decay, insect damage, or water leakage around walls and windows can result in high repair costs for building owners and serious disturbances for building occupants.
