Fiberglass batt insulation consists of pre-cut panels of insulation that come in a variety of lengths, widths, and R-values (resistance of insulation to heat flow). They can be found with or without facing; batts with facing are used on exterior walls, attics, basements, ceilings, and floors. This type of insulation is suited for standard studs and joists in a typical home.
Cellulose insulation is one of the most effective, affordable and environmentally-friendly building products on the market today. It’s produced from 75% to 85% recycled paper products that are combined with fire retarding boric acid or ammonium sulphate; which also helps prevent the formation of mold by improving air flow and serves as an excellent deterrent to insects and rodents. It can be used as wall insulation and attic insulation in existing homes and in new home constructions.
Dense Pack Insulation
Dense Pack insulation is when cellulose/fiberglass is blown into wall cavity effectively sealing the whole cavity providing excellent thermal resistance, sound proof walls and greatly retarding air flow.
There is no better way to seal your home from moisture and air, strengthen the structure of your home, save on energy bills and protect your family’s health from dangerous pollutants than spray foam insulation. Spray foam insulation is a popular choice in insulation.
Applied as a liquid, spray foam expands to 100 times its volume in seconds it fills every crack and creates an air barrier to minimize air leakage and create an airtightness seal. Spray foam is used as wall insulation and as attic insulation.
You’ll be surprised on how many holes, gaps, and cracks are found around the doors, window frames, pipes and plumbing lines, electrical outlets, attics and basements in your home or building. Adding up these small openings can be equivalent to having a window or door open. In older un-weatherized homes, it is estimated that 20-50% of heating and cooling bills are wasted on air leakage (source: Michigan Energy Options).
Spray foam insulation also meets all the qualifying requirements to receive tax credits. For more information I’ve attached the link. https://www.energystar.gov/about/federal_tax_credits
