Batt Insulation: A cost-effective and versatile option, batt insulation is made from fiberglass or mineral wool and comes in pre-cut panels. It’s designed for easy installation between studs, joists, and beams in walls, floors, and ceilings, offering excellent thermal resistance and sound-dampening qualities.

Fiberglass Insulation: Comprising fine glass fibers, fiberglass insulation is a popular choice for its ability to minimize heat transfer and improve energy efficiency. It’s available in batts and rolls for easy application in various areas of a home, providing a budget-friendly solution for enhancing indoor comfort and reducing utility bills.

Blown-In Insulation: Ideal for attics, crawl spaces, and hard-to-reach areas, blown-in insulation is applied using a hose that blows small insulation materials into place. This method ensures complete coverage and fills gaps and spaces with precision, significantly improving a home’s thermal efficiency and air sealing.

Spray Foam Insulation: A high-performance option, spray foam insulation expands upon application, filling cracks and crevices to create an airtight and moisture-resistant barrier. It provides superior thermal insulation and air-sealing properties, making it an excellent choice for reducing energy costs and enhancing indoor air quality.

How Does
Batt Insulation Work?

Batt insulation works by creating a thermal barrier that reduces heat transfer between the interior and exterior of a building. Typically made of fiberglass or mineral wool, batts come in pre-cut sheets that fit between wall studs, floor joists, or ceiling rafters.

During installation, the batts are carefully placed within the framing of a structure, forming a continuous layer that minimizes gaps and ensures consistent coverage. The snug fit and high-density composition of batt insulation helps prevent the conduction of heat, making it an effective and widely used method for improving a building’s thermal performance.

This versatile insulation option offers excellent thermal resistance, is easy to install, and provides a cost-effective solution for keeping your home warm in the winter and cool in the summer.
