Wall Sheathing

M4-EXTERIOR SHEATHING – ICC ES REPORT ESR 3840

Material

The M4-Exterior Sheathing is Fiber reinforced, produced with composite materials of pure Magnesium Sulphate, expanded Perlite, other agents and strong alkali free glass fiber mesh. It is 100% Silica free. The board appears in its natural off white color as standard and has a hard and durable surface.

RESISTANT TO MOLD AND TERMITES

According ASTM D3273 resistance to growth of Mold, the M4-Exterior Sheathing achieved a rating of 10 on a scale of 0 – 10 where 10 is the best possible result. Thus concluding the PH value makes the M4 board very resistant to attack by Termites, and Mold.

FIRE RATED

M4 1/2″ Sheathing passed the ASTM E119 1-hour load bearing fire resistance rating on 2″x4″ wood studs at 100% design load, determined in accordance with the NDS.

CHLORIDE, MOISTURE ABSORPTION

The M4-Exterior Sheathing has limited moisture absorption from air humidity, compared to normal MgO boards, as the M4 board does not contain chloride, resulting in moisture absorption and more importantly NO corrosion of fasteners, aluminium windows, etc.

RACKING SHEAR

Tested according to ASTM E72, M4 1/2″ is a racking shear wall. Governed by a 0.200″ drift limit its allowable load is 458 plf on wood studs and 243 plf on steel studs.

MOISTURE RESISTANT

The board can absorb and release moisture an unlimited number of times, without changes in the board strength properties and the board has less than 0.15% moisture movement according ASTM D1037. The board is vapor permeable.

APPLICATIONS

Exterior Sheathing, SIPs, Modular Construction. For commercial and residential construction, it is a single material replacement for walls requiring racking shear, fire rating and weather barrier. At only 1/2″ it affords more interior square footage space by eliminating material layers. M4 does not rot, warp, expand or contract, is eco-friendly,non-toxic and VOC free.

Underlayment

The M4 Fire Restrictive Barrier 1/8 in. (M4 FRB)

The M4 FRB is an innovative Underlayment panel which is ASTM proven as a Water Restrictive Barrier and can boost most structural wood framed exterior wall assemblies to a 1-hour fire-rating.

How to use

Simply install a single layer of the M4 FRB boards to the exterior facing of any 7/16 in. sheathing of DOC PS1 or DOC PS2 third party approved OSB or Plywood. The M4 FRB is installed Off set to the 7/16 in. sheathing joints

What is the M4 FRB ?

M4 FRB is composed of a proprietary cement slurry bound with multiple layers of high strength, premium and alkali-resistant fiberglass mesh. Only those raw materials with the highest purity and quality are selected. Each batch goes through extensive QC testing before entering the marketplace. Our rigorous R&D
and extensive third party testing has made us a leading producer of non-combustible building products. M4 FRB is lightweight, off-white in color and has a hard and Exterior Sealed durable surface.

Fire Rated:

The M4 FRB is an innovative Underlayment panel which is ASTM proven as a Water Restrictive Barrier and can boost most structural wood framed exterior wall assemblies to a 1-hour fire-rating.

Wood studs – ASTM E119-20 1 hour Fire Rated, load-bearing construction

1-hour fire exposure from either side in fire-rated structural exterior wall assemblies to be used in Type II, III and V construction. (Allowable Axial load of 2,374 lbs/ft /34.65 kN/m specified by the 2018 NDS).

Water Restrictive Barrier

M4 FRB is factory sealed for exterior applications and tested to WRB standards ASTM E 331 and ASTM E 96. Board Seams and Joints must be sealed with liquid flashing or flashing tape fulfilling IBC as per AAMA 711 and installed per supplier instruction.

M4 FRB Other testing:

M4 Other testing:

Moisture resistant

The board can absorb and release moisture an unlimited number of times, without major softening changes in the board strength properties and the board has less than 0.15% moisture movement according to ASTM D1037-99.

Moisture absorption rate

The M4 samples were tested in a controlled climate with 94% RH and 72 F over 720 hours (30 days). Testing was performed together with samples from two significant boards suppliers. The test result of moist absorption rate was:
M4 after 3 days 15% other board suppliers 32%. equal to more than 100% higher moist absorption. After 10 days of absorption, the result was 22% for the M4.
M4 can be factory antiwater sealed (as WRB) for exterior application so water absorption is below < 5%.

Resistant to Mold and Termites

According to ASTM D3273-12 resistance to the growth of Mold, the M4-Exterior Sheathing achieved a rating of 10 on a scale of 0 – 10, where 10 is the best possible result. Thus concluding the PH value makes the M4 board very resistant to attack by Termites, and Mold.

Corrosion Resistance to Metal

The M4-Exterior Sheathing is 100% Chloride ion free and does not have halogenide as a problem as for some other sheathing product like most Mgo boards and does not corrode aluminium, copper metals and steel screws and steel. Corrosiveness test was performed per section 13.8 of ASTM C665-12 and was performed over 720 hours insted of the standard of 96 hours, none of the metals had any corrosion sign compared to the control samples not connected to the M4 after the extended 720 hours testing.
