Many homeowners and property managers ask, “What is fiberglass insulation?” Fiberglass insulation is a widely used material that helps regulate indoor temperatures and reduce energy costs. Made from tiny glass fibers, it creates a thermal barrier that keeps warm air in during winter and out during summer. For residents and business owners in Sunnyvale, TX, it’s an affordable and effective solution for enhancing indoor comfort. But how does it work, and why is it so popular? Let’s break it down.
How It Works and Where It’s Used
This insulation type works by trapping air within its fibers, which slows heat transfer. The result? Lower energy bills and less strain on heating and cooling systems.
Where Is It Used?
- Attics – Prevents heat loss and air leaks.
- Walls – Helps maintain stable indoor temperatures.
- Basements & Crawl Spaces – Reduces drafts and moisture risks.
- Commercial Buildings – Increases energy efficiency and supports sustainability.
Types of This Insulation
- Batt Insulation – Comes in pre-cut panels, ideal for attics and walls.
- Blown-in Insulation – Loose fibers that fill gaps effectively.
- Rigid Board Insulation – High-density sheets for extreme insulation needs.
Is It Safe for Homes and Businesses?
Does It Contain Asbestos? Modern products do not contain asbestos. However, older buildings might have outdated materials that should be tested before removal. Can It Get Moldy? While this insulation does not support mold growth, excessive moisture can cause mold to form in surrounding materials. Proper installation and ventilation help prevent this issue.
