Apartment construction demands insulation that does more than resist heat transfer. Party walls need fire ratings. Floor/ceiling assemblies need STC ratings. Bathrooms need moisture resistance. Prestige supplies the full range — fiberglass batts for exterior walls and floors, and mineral wool for the assemblies where fire and sound performance are non-negotiable.
IBC requires 1- or 2-hour fire ratings at unit separations. Mineral wool (SAFB) is UL-listed for use in tested assemblies that meet these requirements without additional layers of drywall.
Most jurisdictions require STC 50+ for floor/ceiling assemblies in multifamily. Mineral wool AFB in the joist cavity is the most cost-effective way to achieve compliant STC ratings.
Zone 4+ requires R-15 HD for 2×4 exterior walls and R-21 for 2×6. We stock both in volume to match your framing schedule.
IBC-compliant party walls typically use mineral wool (SAFB) in the stud cavity combined with drywall on each side. The specific UL assembly determines stud spacing and layer count. We stock mineral wool for these assemblies.
Yes. We stock mineral wool AFB in standard thicknesses for joist-cavity applications. These assemblies typically achieve STC 50–54 depending on the decking and ceiling system.
No minimum. Whether it’s 10 bags for a punch list or 500 bags for a full building, we quote any quantity.
