FAQ’s

Everything You Need to Know About Spray Foam, Insulation, and Energy Savings in Texas

At Apex Foam Solutions, we believe an informed homeowner is a confident homeowner.

Here are answers to the most common questions our customers ask before, during, and after their insulation projects.

Spray Foam Insulation FAQs

1. What’s the difference between open cell and closed cell spray foam?

Open-cell foam is softer and more flexible, great for attics, walls, and soundproofing.

Closed-cell foam is denser and water-resistant ideal for roofs, crawl spaces, and metal buildings.

We’ll recommend the best type based on your structure and budget.

• Open-cell: typically 5.5–6 inches in attics or roof decks (R-20+).

• Closed-cell: around 2–4 inches (R-14 to R-21).

Exact thickness depends on your energy goals and local building codes.

We recommend removing old insulation first, especially if it’s dirty, moldy, or compressed.

Spray foam needs a clean surface to properly bond and seal air gaps.

Yes — once cured, spray foam is completely safe and non-toxic.

Our technicians follow strict ventilation and PPE guidelines during application to protect your home and air quality.

Properly installed spray foam can last over 50 years without losing its R-value or effectiveness  it won’t sag, settle, or deteriorate like fiberglass or cellulose.

Absolutely. Open-cell spray foam is excellent for absorbing sound between rooms, floors, or walls  perfect for home offices, media rooms, or multi-family properties.

Pricing depends on square footage, foam type, and thickness, complexity of the work.

We offer free estimates and financing options through partners like Synchrony, Hearth and greensky

Yes. Closed-cell spray foam is the best option for metal buildings, warehouses, and barns  it prevents condensation, strengthens the structure, and improves temperature control.

Attic & Fiberglass FAQs

9. Should I remove old insulation before installing spray foam or fiberglass?

Yes. Old or dirty insulation traps dust, rodents, and moisture.

We offer complete attic insulation removal and cleanup before new installation to ensure top performance.

Blown-in fiberglass is a lightweight, efficient material applied using a hose system.

It’s ideal for attics, walls, and ceilings  offering quick installation and strong R-value performance.

Most Texas homes need R-38 to R-49, which equals about 14–16 inches of fiberglass or 5–6 inches of open-cell spray foam.

Proper attic ventilation:

• Reduces heat buildup in summer 

• Prevents moisture and mold

• Extends roof life 

We install ridge vents, air hawks, 

Solar / electric fans , whirlybirds and soffit systems to improve airflow.

In some cases, yes.

For example, you can use spray foam on walls for air sealing and blown-in fiberglass in attic floors for extra R-value.

We’ll recommend the best hybrid system for your home.

Air Sealing & Moisture Control FAQs

14. How does spray foam help with moisture and air leaks?

Closed Cell Spray foam acts as an air and vapor barrier, sealing gaps that let in humid air or water vapor  protecting against mold, mildew, and energy loss.

It’s a protective coating applied over spray foam in certain areas (like attics or crawl spaces, commercial buildings) to meet fire safety codes.

We use approved materials such as DC315 to ensure full compliance.

No — if installed correctly with proper ventilation, spray foam creates a controlled environment that improves air quality and efficiency, not a “trapped” space.

Concrete Lifting & Leveling FAQs

17. How does foam concrete lifting work?

We inject specialized polyurethane foam beneath sunken concrete slabs.

The foam expands, lifting and leveling driveways, patios, or sidewalks   quickly and without messy demolition.

Most jobs are completed in 1–3 hours, and the surface is ready to use within minutes after installation.

Our polyurethane lifting foam is waterproof and long-lasting, designed to perform for decades without erosion or settling.

We offer flexible terms for residential and commercial customers.
