Our Insulation Services Batt insulation is fiberglass blanket insulation that comes in rolls or sheets and designed for easy handling. It is used between framings such as studs and joists. Batts are available in a variety of lengths, widths, and R-values. Loose fill insulation is blown-in with a machine directly into the attic. Blowing in insulation is faster than installing batts and offers better coverage by completely covering the attic floor. Spray polyurethane foam (SPF) is a spray-applied plastic that can form a continuous insulation and air-sealing barrier on walls, roofs, around corners, and on all contoured surfaces. Spray foam insulation is known to resist heat transfer extremely well and offers a highly effective solution for reducing unwanted air infiltration through cracks, seams, and joints.
