Building Materials Insulation
Tyvek
Different insulation materials:
Fiberglass: Made from fine glass fibers, it is commonly used in batt or blanket form.
Mineral Wool: Similar to fiberglass, it is made from molten mineral fibers.
Cellulose: Made from recycled paper, it is often used as loose-fill insulation.
Spray Foam: A liquid that expands into foam and provides excellent air sealing properties.
Rigid Foam: Panels made of materials like polystyrene, polyisocyanurate, or polyurethane.
R-Value: The R-value measures an insulation material's resistance to heat flow. A higher R-value indicates greater resistance and better insulation performance.
Application areas: Attics: Insulating the attic helps prevent heat loss or gain through the roof.
Walls: Insulating exterior walls improves energy efficiency and thermal comfort.
Floors: Insulating floors over unheated spaces (e.g., crawl spaces) reduces heat loss.
Basements: Insulation in basements or foundation walls helps maintain consistent temperatures.
