Description

Knauf Hullboard with ECOSE Technology is a light-weight insulation board of 3.7 ounces per square foot per inch thickness with one surface designed to have either glass cloth facing applied in a fabricator’s facility or brattice cloth applied by marine insulation applicators in the field.

ECOSE Technology

ECOSE Technology is a revolutionary new binder chemistry that makes Knauf Insulation products even more sustainable than ever. It is based on rapidly renewable bio-based materials rather than nonrenewable petroleum-based chemicals traditionally used in fiberglass insulation products. ECOSE Technology reduces binder embodied energy and does not contain phenol, formaldehyde, acrylics or artificial colors.

Application

Knauf Hullboard with ECOSE Technology has a low thermal conductivity of 0.23 BTU•in./hr•sq.ft.•°F at a mean temperature of +75°F (+24°C). It is designed for use as a thermal insulation for bulkheads, beams, decks, shell plating and ducts aboard Naval, Coast Guard and domestic ships.

Features and Benefits

Hullboard is easy to fabricate and install and can be kerfed per the requirements of Military Specification MIL-I-742F to fit irregular surfaces. The product resists the effects of vibration and slumping, providing an in-place performance that meets all required standards. The product is moisture resistant and is not damaged by temporary exposure to fresh or salt water. The product also will not provide sustenance to vermin, will not rot and has no objectionable odor.

Sustainability

• Carbon negative: meaning Knauf insulation products used for thermal insulating purposes recover the energy that it took to make them in just hours or a few days, depending on the application.
• Once installed, the product continues to save energy and reduce carbon generation as long as it is in place.

Fiber glass insulation with ECOSE Technology  contains three primary ingredients:

• Sand, one of the world’s most abundant and renewable resources
• Post-consumer recycled bottle glass
• ECOSE Technology which reduces binder embodied energy by up to 70%

Application and Specification Guidelines

Knauf Hullboard is manufactured to be used by fabricators for facing with glass cloth for use on ships. The material can also be applied plain or field-finished with brattice cloth in lieu of pre-faced material for retrofit applications. The product can be kerfed either by rotary sawblade, groove cutters or hand grooving tools to accommodate I-beams, duct work or other special requirements. The board can be impaled over fasteners which are pre-welded in position between stiffeners, generally 12" (305 mm) on center and 3" (76 mm) from the longitudinal and horizontal joints of the insulation board. The fabricated boards can be finished with approved tapes and caps as per specification requirements.

Caution

Fiber glass may cause temporary skin irritation. Wear long-sleeved, loose-fitting clothing, head covering, gloves and eye protection when handling and applying material. Wash with soap and warm water after handling. Wash work clothes separately and rinse washer. A disposable mask designed for nuisance type dusts should be used where sensitivity to dust and airborne particles may cause irritation to the nose or throat. During initial heat-up to operating temperatures above +350°F (+177°C), an acrid odor and some smoke may be given off as a portion of the bonding material used in the insulation begins to undergo a controlled decomposition. If natural convection is not adequate in confined areas, forced ventilation should be provided in order to protect against any harmful fumes and vapors that might be generated.

Fiber Glass and Mold

Fiber glass insulation will not sustain mold growth. However, mold can grow on almost any material when it becomes wet and contaminated. Carefully inspect any insulation that has been exposed to water. If it shows any sign of mold it must be discarded. If the material is wet but shows no evidence of mold, it should be dried rapidly and thoroughly. If it shows signs of facing degradation from wetting, it should be replaced.
