L&W Supply is your source for the latest insulation products from traditional fiberglass batts to rigid insulation. We offer leading Fiberglass and Mineral wool insulation products to suit a variety of construction needs and you will find the two most preferred types of rigid insulation at our locations.
Fiberglass insulation is a cost-effective thermal and acoustical barrier for energy-efficient construction. Batts are available in a wide range of R-values (typically R-11 to R-38) and thicknesses to meet most thermal specifications. Easy to install, fiberglass provide excellent acoustical properties and will reduce sound transmission when installed properly in partition walls and acoustical ceiling and floor systems. Acoustical/ thermal insulation can improve STC ratings in wood stud construction by 3 to 5 points and metal stud construction by 8 to 10 points depending on the wall configuration.
Mineral Wool Insulation
Mineral wool insulation is made from natural rock and slag which makes it fire resistant, non-combustible and capable of handling temperatures in excess of 2000 °F. The superior fire performance and moisture resistance of mineral wool has also made it an attractive option for continuous insulation on the building exterior. In addition, the density of mineral wool makes it resistant to air flow and gives it outstanding acoustical performance. Using mineral wool as part of a wall or floor assembly can dramatically improve the sound performance of the partition.
XPS Extruded Polystyrene Insulation
Uses in agricultural, residential, commercial, refrigeration, new construction and remodels. Extruded Polystyrene (XPS) is a rigid thermoplastic made by mixing molten polystyrene with a blowing agent. The mixture is then extruded through a die that creates many small, rigid closed cells that provide the panel with its strength, thermal insulation and water resistant properties. XPS is an excellent choice to reduce heat loss or gain and provides a protective continuous insulation barrier. XPS is available in a wide variety of thicknesses, surface, and edge profiles.
Polyiso is the #1 insulating product available today. Polyiso can be used in residential and commercials structures, on the roof or on the wall. Using polyiso enhances a building’s performance by keeping heat loss to a minimum, blocking thermal bridging, and reducing your monthly operating cost.
Polyiso panels are available with a variety of facers:
