Seal Your Band Joists,

Save Energy

Prevent drafts, frozen pipes, and uneven floors by properly insulating your band joists. Atlas makes your home more comfortable and energy-efficient from the foundation up.

50%

Fewer Drafts – Warmer first floors

Up to 25%

Energy Savings – Reduce heating/cooling costs

100%

Protection – Against moisture and air leaks

A Critical Area Often Overlooked

Band joists run along the perimeter of your home where the first-floor joists sit on the foundation walls. These areas are often major sources of air leaks due to numerous framing connections, mechanical penetrations, and electrical pathways. Uninsulated band joists can lead to colder basements, icy floors, and even frozen pipes during winter.

Traditional fiberglass in these areas is often ineffective because it doesn’t stop air movement. Atlas replaces old insulation with spray foam to air-seal and insulate band joists, improving comfort, energy efficiency, and reducing strain on your heating and cooling system.

What’s Included in Your

Band Joist Upgrade?

Our service ensures complete insulation and air sealing for long-lasting comfort.

How It Works

From inspection to insulation, Atlas makes your band joists airtight and energy-efficient.

Inspection

Identify leaks, moisture, and old insulation issues.

Preparation

Remove old fiberglass and install vapor barrier.

Spray Foam Installation

Air-seal and insulate band joists for maximum performance.

Final Check

Verify insulation coverage and improved energy efficiency.

Why It Matters:

Pros vs. Cons

Neglecting band joists can create drafts, energy loss, and uncomfortable floors.

Frequently asked questions

How do I know if my band joists need insulation?

Look for drafts near the basement perimeter, cold first floors, condensation on ducts, or frozen pipes in winter.

What type of insulation do you use?

We use closed-cell spray foam, which seals air leaks, stops drafts, and outperforms traditional fiberglass.

Will insulating band joists reduce my energy bills?

Yes. Properly insulated and sealed band joists prevent heat loss and reduce the workload on your HVAC system.

Can this be done without removing drywall?

Yes. Atlas can access most band joist areas without major demolition, especially in unfinished basements or behind accessible ceilings.
