EXACOR Underlayment 

EXACOR sound reduction underlayment panels are specifically engineered to meet the fire-rating, sound-rating and dimensional stability requirements of most multifamily and light commercial jobsites. Made of magnesium oxide and an integrated mesh core, EXACOR underlayment panels are fire resistant. In addition, EXACOR underlayment panels can offer a base for floor coverings that eliminates the need for gypsum underlayment and installs 30% faster than gypsum underlayment.

EXACOR Wall Sheathing

EXACOR wall sheathing panels are fire-resistant, high-density, structural magnesium oxide cement panels. When used as an exterior wall sheathing, EXACOR panels can replace other sheathing materials in certain assemblies, potentially reducing the number of layers required.

EXACOR wall sheathing can be used in exterior walls of Type III construction greater than 40 feet in height above grade plane when used in accordance with the applicable NFPA 285–compliant designs as listed in ESL-1290. EXACOR sheathing is not approved for use on Type I or II buildings except as noted in ESR-4635.

  • Speed & Ease of Installation: Installs with just a single trade and can eliminate the need for gypsum underlayment
