Arctic Insulation Contractors • May 26, 2025

When it comes to improving energy efficiency, soundproofing, and indoor comfort, open-cell spray foam insulation is a top choice. This lightweight, cost-effective insulation expands to fill spaces and create a seamless air barrier, making it ideal for homes and businesses looking for an affordable yet high-performance insulation solution.


At Arctic Insulation Contractors, we specialize in expert open-cell spray foam installation, ensuring our customers experience enhanced comfort and energy savings year-round.

What is Open-Cell Spray Foam Insulation?

Open-cell spray foam is a low-density, expanding foam that fills cracks, gaps, and cavities while remaining soft and flexible. Unlike closed-cell spray foam, open-cell foam has a spongy texture due to the open nature of its air pockets, which contributes to its excellent soundproofing and breathability.


This insulation type is perfect for interior applications where flexibility and cost-effectiveness are key.

Benefits of Open-Cell Spray Foam Insulation

1. Cost-Effective Insulation Solution

Open-cell spray foam is more affordable than closed-cell insulation, making it a budget-friendly option for homeowners and businesses looking for energy-efficient insulation.

2. Excellent Soundproofing

Thanks to its structure, open-cell spray foam provides superior noise reduction, making it an excellent choice for:


  • Interior walls
  • Office spaces
  • Apartment buildings
  • Home theaters

3. Airtight Seal for Energy Savings

Open-cell foam expands to seal gaps and cracks, preventing drafts and air leaks that cause energy waste. This results in lower heating and cooling costs year-round.

4. Environmentally Friendly & Breathable

Open-cell spray foam allows for moisture permeability, which helps prevent trapped condensation that could lead to mold growth. Its eco-friendly composition also makes it a sustainable insulation choice.

5. Flexible and Lightweight

Unlike closed-cell foam, open-cell spray foam remains soft and flexible, allowing for natural structural movement without compromising insulation performance.

Best Applications for Open-Cell Spray Foam

Open-cell spray foam is ideal for various indoor applications, including:


  • Interior Walls – Reduces noise transmission between rooms.
  • Attics & Ceilings – Fills gaps and improves energy efficiency.
  • Basements – Helps regulate temperature and prevent moisture buildup.
  • Crawl Spaces – Improves air circulation and prevents cold drafts.
