Dirty Jobs Part 3: Home Insulation

HATTIESBURG, MS (WDAM) - Sometimes, a dirty job can be right over your head. 

Armor Insulations Company and the unique, contemporary method they use to insulate homes and businesses know a thing or two about dirty jobs.

They specialize in Polyurethane Spray Foam, Blown-in, and Batt insulation for residential and commercial locations, new or weathered construction. 

While spray foam insulation is more expensive to install than fiberglass, home and business owners may notice that the benefits of SPF outweigh the greater initial cost.

Before insulating a home, workers have to protect themselves by wearing proper protective wear to avoid exposure to potentially hazardous chemicals. 

In this case, a whole body suit, a ventilated helmet and gloves are used to protect the person spraying the insulation. 

Two chemicals combine to create the foam which is later scraped until the surface is flat and even. 

Technical Information:

Open-cell foam contains tiny cells of the foam that are not completely closed.  They are broken and air fills all of the open space inside the material.  This makes the foam softer feeling than closed-cell, like a cushion or packaging material for fragile object being shipped.   Open-cell is the most common in homes.  

Closed-cell spray polyurethane foam (SPF) is one of the most advanced insulation solutions available. Closed-cell foam contains tiny foam cells that are closed and packed together. Closed-cell has higher R-value per inch (6.2 vs. 3.5), higher strength, and is more resistant to air and water leakage; it is also more expensive than open cell.  They are filled with a gas that helps the foam rise and expand and become a greater insulator, providing nearly twice the R-value of open-cell foam per inch.  The liquid state when it's applied allows the spray foam to fill fine cracks and holes that traditional fiberglass alternatives can't penetrate.
