Question & Answers for Insulation

 R-Value measures insulation’s ability to resist heat transfer. The higher the R-Value, the better the insulation’s thermal performance. 

 For Missouri residents, the recommended attic R-Value is R-38 to R-60, depending on your home’s heating and cooling system and insulation needs.

 Measure the depth of your attic insulation in inches and multiply by the R-Value per inch for your insulation type (e.g., fiberglass, cellulose). If you’re unsure, schedule a professional assessment. 

 Yes, insulating your crawlspace helps prevent energy loss, reduces drafts, and keeps floors warm. Properly sealed and insulated crawlspaces improve energy efficiency and comfort.

 Insulation should be removed if it is damaged by water, fire, or pests, or if it has become contaminated with mold, feces, or urine. Such conditions can lead to poor air quality and health risks.

 Yes, proper attic ventilation helps regulate temperatures, reduce moisture buildup, and extend your roof’s lifespan. Ventilation ensures insulation performs effectively.

 Yes, as long as the existing insulation is in good condition and free of damage, new insulation can be added on top. Damaged insulation must be removed first.

 Drill and Fill is a process where small holes are drilled into walls, and insulation is blown into empty wall cavities to improve energy efficiency and comfort. It’s ideal for older homes with uninsulated walls.

 Baffles are installed in attics to maintain proper ventilation by preventing insulation from blocking airflow. They help eliminate moisture, prevent mold, and ensure insulation stays in place.

 Blown-in insulation (fiberglass or cellulose) is the best choice for attics. It provides excellent coverage, is easy to install, and offers high thermal performance. 

 Re-insulating improves energy efficiency, lowers energy bills, enhances indoor comfort, and reduces the workload on heating and cooling systems. Most homeowners see a 20-30% reduction in energy costs.

 Yes, insulation is effective at reducing noise transfer between rooms or from outside, making your home quieter and more comfortable.

 Yes, wet insulation loses its effectiveness and can promote mold growth. It should be removed and replaced promptly.

 Blown-in insulation may settle slightly, but when installed correctly at proper densities by certified professionals, it maintains its performance.

 Cellulose insulation is the most eco-friendly option, made from 75-85% recycled materials like paper and treated with non-toxic fire retardants.

•  High energy bills
• Uneven room temperatures
• Drafts
• Heating or cooling systems running constantly

 Retrofit insulation refers to upgrading or adding insulation to an existing home to improve energy efficiency and comfort.

 Key areas include:

• Attics
• Walls (interior and exterior)
• Crawlspaces
• Basement walls
• Floors over unheated spaces
• Cathedral ceilings
• Garage ceilings and walls

•  Fiberglass: Can irritate the skin and eyes during installation; use goggles, gloves, and masks.
• Cellulose: Eco-friendly and non-toxic.
• Proper installation minimizes risks and ensures safety for homeowners.
