When it comes to home comfort, energy savings, and indoor air quality, few upgrades make as big of an impact as insulation. Whether you’re building a new home, remodeling, or updating an existing structure, the type of insulation you choose plays a major role in performance and efficiency.
At Sealtite Insulation & Slabjacking, we’ve been helping homeowners across Central Illinois since 2004 find the right insulation solutions for every type of home and budget. Here’s everything you need to know to choose the best insulation for yours.
Why Insulation Matters
Insulation acts as a barrier that slows the transfer of heat between the inside and outside of your home. The better your insulation, the easier it is to maintain a comfortable temperature—reducing the strain on your HVAC system and lowering energy bills.
But insulation does more than keep you warm in winter and cool in summer—it also helps:
-
Improve indoor air quality by sealing out allergens and pollutants.
-
Reduce noise between rooms and from outside.
-
Prevent moisture buildup that can lead to mold growth.
-
Strengthen your home’s structure and enhance durability.
Common Types of Home Insulation
Different areas of your home require different insulation materials and installation methods. Here are the most common options:
1. Spray Foam Insulation
Spray foam is one of the most effective and versatile insulation types available today. It expands to fill cracks and gaps, creating an airtight seal that prevents heat loss and moisture intrusion.
-
Open Cell Foam: Softer, flexible, and excellent for soundproofing interior walls and attics.

- Closed Cell Foam: Dense, moisture-resistant, and adds structural strength—ideal for exterior walls, crawl spaces, and roofs.

✅ Best for: Superior air sealing, energy savings, and long-term durability.
2. Cellulose Insulation

Made from recycled paper treated for fire and pest resistance, cellulose is an eco-friendly option that performs well in attics and wall cavities. It provides good coverage and helps reduce air leaks when installed correctly.
✅ Best for: Existing homes and retrofit projects looking for a green, cost-effective solution.
3. Fiberglass Insulation

Fiberglass insulation is one of the most widely used materials, available as batts, rolls, or loose-fill. It’s affordable, effective, and works well in attics, crawl spaces, and between studs in new construction.
✅ Best for: Homeowners seeking a reliable, budget-friendly insulation option.
4. Mineral Wool (Rock Wool) Insulation

Mineral wool is made from natural rock and recycled slag. It offers high fire resistance, soundproofing, and moisture control.
✅ Best for: Basements, exterior walls, and areas needing fire and sound protection.
How to Choose the Right Insulation for Your Home
The “best” insulation depends on your goals, home design, and budget. Here’s what to consider:
- Energy Efficiency Goals – For maximum energy savings, spray foam offers the highest performance.
- Moisture Control – Closed cell foam and mineral wool both resist water and help prevent mold.
- Sound Control – Open cell foam and mineral wool are excellent sound barriers.
- Budget – Fiberglass and cellulose provide affordable, effective insulation for large areas.
- Longevity – Spray foam has a long lifespan and maintains its performance over time, often outlasting traditional materials.
