K-13
K-13 is a high-performance, spray-applied, thermal and acoustical finish system, consisting of natural, plant-based fibers, and specialty water-based adhesive. K-13 is spray-applied to substrates of ribbed metal decking, wood, concrete, gypsum/drywall, and can adhere to complex surfaces such as domes.


Monoglass
Monoglass is a spray-applied, non-combustible thermal and acoustic insulation composed primarily of recycled glass fibers. It’s designed to bond to various surfaces like concrete, wood, steel, and even other insulations, providing both thermal and acoustic performance. Monoglass is known for its versatility, ease of application, and ability to reduce noise and control reverberation in various environments
Sonoglass
Sonoglass is a spray-applied acoustic and thermal insulation product known for its ability to reduce noise and improve acoustics in various spaces like venues, churches, and gymnasiums. It’s a fiberglass-based material that can be applied to various surface shapes, including curved and irregular ones, and provides a more finished appearance compared to standard spray-on insulation.


CELLU-Shield
Isolatek International’s CELLU-SHIELD® is a spray applied cellulose material developed specifically to meet thermal and acoustical needs. CELLU-SHIELD is ideally suited for light gauge steel panels, concrete slab construction, underside of roof decks, cold storage facilities, or when a high thermal value (R-value) is required. In addition to its thermal properties, CELLU-SHIELD can be effectively used for acoustical treatment, due tot the material’s high noise reduction coefficient.
