Blown-in insulation creates an extra fluffy layer of effective insulation in the attic — a convenient choice that can be blown in over existing insulation or in between walls and ceiling joists without disturbing structures. SprayTight installs batt and blown-in insulation for residential, commercial, and new build construction projects across Michigan.
Blown-In Insulation
Loose-fill fiberglass or cellulose can be blown onto your attic floor, between walls, or into other spaces that may require insulation. Blown-in insulation can easily cover large areas and will fill in areas with tight spaces and angles — ideal for attics with irregular framing, wiring, and hard-to-reach corners.
Because it installs without disturbing existing structures, blown-in is one of the fastest, least invasive ways to bring an under-insulated Michigan home up to modern comfort standards and cut heating bills. Pair it with air sealing or attic spray foam for the best results, and see the types of thermal insulations to compare options.
Batt Insulation
There are many benefits to consider when choosing batt insulation for your Michigan home. It is a cost-efficient option, it offers varying degrees of sound absorption, and it can reduce energy costs. Plus, it is available in different materials and thicknesses to help achieve optimal energy efficiency.
Batt insulation — often referred to as blanket insulation — generally consists of fiberglass, mineral wool, and even denim cotton. It is pre-cut and sized to fit most standard building dimensions and is best suited for residential houses and commercial applications. Most commonly it is used between wall studs, attic rafters, and ceiling joists, insulating floors, walls, ceilings, and attics as well as basements and crawl spaces.
