Megaboard Sheathing delivers remarkable shear strength, fire resistance and structural performance in a single layer solution.

Fastened to steel or timber-framing studs, Megaboard Sheathing can achieve more than 3,500 PLF nominal shear capacity to resist seismic and lateral wind forces on your building.

In common with all Megaboard products, Megaboard Sheathing is non-combustible per IAMPO listings for up to 2-hour fire rating, and has exceptional load-bearing strength.

Uniquely, these exceptional composite characteristics come from a single integral panel – a lightweight solution which cannot delaminate and is resistant to water, mold and insect damage.

Features

included

Non-Combustible

Non-combustible per IAPMO listings (ASTM E136 – Non-Combustible). IBC & IRC approved for up to 2-hour fire ratings.

included

Strong

Shear capacity of more than 3,500PLF against seismic and lateral wind, plus exceptional structural load-bearing performance.

included

Quick & Simple to Install

Lightweight, durable and single trade fitted for on-site efficiency and reduced build times.

included

Water, Mold & Insect Resistant

Inorganic cementitious materials will not grow mold (per ASTM G 21 0/0), and ensure zero nutritional value for complete resistance to termites and all wood-boring insects.

included

Sound Insulating

A unique formulation which can help building designers and contractors achieve critical sound ratings, with the ability to reach 55+ STC/IIC ratings.

included

Dimensionally Accurate & Stable

Manufactured to class-leading tolerances for on- and off-site precision. Resistance to water means panels remains structural while wet, and will not delaminate, warp, expand or bow.
