Good thermal performance	Requires protective gear during installation
Fire-resistant	May settle over time

Always wear protective clothing and a mask when installing fiberglass insulation to avoid irritation from glass fibers.

Example: Consider a typical residential attic. Installing fiberglass batts between the attic joists can dramatically reduce the amount of heat escaping from the house in the winter and entering the house in the summer.

Foam Board Insulation

Foam board insulation consists of rigid panels made from materials such as polystyrene, polyisocyanurate, or polyurethane. These panels provide high insulation value and are often used in walls, floors, and roofs.

High R-Value: Foam boards offer a high R-value per inch, making them very effective insulators.
Moisture Resistant: These boards resist moisture, making them suitable for basements and crawl spaces.
Durable: Foam board is highly durable and can provide long-lasting insulation.

Pros	Cons
High R-value	Can be more expensive
Moisture resistant	Must be properly sealed
Durable	Not flexible

Foam board insulation is also known for its use in insulating concrete forms (ICFs). ICFs are formwork for concrete that stay in place as permanent building insulation for energy-efficient, cast-in-place, reinforced concrete walls, floors, and roofs.

Spray Foam Insulation

Spray foam insulation is a versatile insulation that can be applied to various surfaces and tight spaces. It is made from a mixture of isocyanate and polyol resin, which reacts quickly to expand and contract.

Air Tight: Spray foam creates an airtight seal, preventing air leaks.
High R-Value: This insulation offers one of the highest R-values per inch.
Moisture Barrier: It also acts as a moisture barrier, reducing the risk of mold and mildew.

Pros	Cons
