Protection of power line infrastructure where the fire-resistant laminate resistant laminate can be field, or factory applied to wood or combustible power poles to protect during wildfires. Protection of combustible infrastructure such as wooden rails or road bridges where the fire-resistant laminate is applied around the combustible substrate to protect during wildfires. Today's construction projects and ever-changing building codes are demanding a higher level of fire protection than ever before. The present invention provides a system and method that is required to successfully pass industry testing (including but not limited to ASTM-E119 testing) required to meet applicable building code requirements. No invention is known to have all of the features and advantages of the present invention.

FIELD OF THE INVENTION

The invention herein relates to systems and methods used in the pre-manufacturing stage, during final inline manufacturing, or post-manufacturing in the field of engineered wood products (EWP), including but not limited to oriented strand board (OSB), plywood-type panels, and the production of I-joists, wherein a multi-layered barrier of fire retardants and vapor/moisture barrier protectant is applied onto engineered wood products to enhance their durability against fire and weather when applied to at least one surface.

Preferred but not required in all applications, it is contemplated that each layer of protection applied provides the proper amount of heat and fire protection necessary to pass all industry testing and not be just a decorative film-type laminate including but not limited to poly type liners and/or foam tapes with basically no added fire protection when compared to the system and method of the invention disclosed herein.

It is further contemplated that this multi-layered barrier can be in the form of a master roll-type product for easy production and manufacturing. A master roll product has a low thickness and low weight and does not significantly affect calculations of joists' thickness and weight. In one embodiment, the thickness is in a range of 0.8 millimeters to 2 millimeters thick and an average of 1.3 millimeters thick, is dry and no does not contain any wet chemicals. In one embodiment, the range of weight is about 650 grams/square meter and under 1,000 grams/square meter. In other embodiments, the range of thickness and weight is adjustable to fulfill the requirements of an application based on conditions and customer specifications.

In one embodiment, a master roll product may also be composed of, but not limited to, one or more of the following; fire retardant chemicals, plastics, rubbers, foils, papers, silicon-coated fiberglass, cloth, paper, metal, aluminum foil, and copper foil, plastic film materials including Polyvinylchloride (PVC), Polyethylene (PE), Polyurethane (PU), Polyethylene terephthalate (PET), Polypropylene (PP), and Thermoplastic Polyurethane (TPU) and equivalents. Thus the materials alone or in combination provide functions including decoration, waterproofing, flame resistance, and wear resistance.

The present invention includes a thermal barrier for assistance in passing industry fire testing, as well as a moisture and/or vapor barrier to protect both the engineered wood product and fire retardant barrier against extreme weather to assist in the passing of certain industry testing, including but not limited to ASTM-E119 testing. The present invention will withstand both fire testing and weather durability testing necessary for engineered wood products sold and used in current residential and commercial construction markets.

The present invention system and method incorporates the use of liquid and/or solid fire resistance and fire retardant chemicals, including but not limited to intumescent type chemicals in both liquid form or dry form, including but not limited to a pre-manufactured type intumescent paper in rolls or sheet-type product. These types of products become used as a part of the application process and are laminated and secured to an engineered wood panel product or I-joist providing enhanced fire protection as well as extreme weather conditions to withstand both fire and weather durability testing, including that identified in ASTM-E119, CAN/ULC S-101, ICC-ES AC14, ICC-ES AC264, NFPA 286, NFPA 275, CAN/ULC S-124, CAN/ULC S-145 and other national and international standards

It is further contemplated that the multi-barrier system and method of the present invention will be laminated to the engineered wood panels or I-joist product. This lamination process will include but not be limited to the use of thermal adhesives or other types of chemical adhesion type methods. There is no other product or technology known that includes all the benefits and added value of the present invention, having the ability to successfully pass the required testing needed for building code approval while also allowing the present invention product to be sold and used in today's residential and commercial construction industries.

The present invention will significantly enhance today's engineered wood products (EWP) and assemblies by providing enough protection against fire and extreme weather conditions to pass required testing. Several companies have tried for several years and spent hundreds of thousands of dollars attempting to meet the harsh testing requirements necessary to manufacture a product equivalent to the present invention, incorporating both the fire-retardant properties in addition to the durability and protection against extreme weather. There is no other system and method known that has all of the benefits and advantages provided by the present invention.

The terms “multi-layered barrier of fire retardant and vapor/moisture barrier protectant” and “multi-layered barrier” as used interchangeably herein refer to the same product with no change in meaning.

Wireless digital sensors and digital electronics and communication devices may include at least every smartphone that has a 3-dimensional coordinate system. Based on this system, sensors in your smartphone detect and record changes in real time. Motion sensors detect the movement, acceleration, and rotation along the three axes of the device's coordinate system. Some examples of motion sensors are accelerometers, gravity sensors, and gyroscopes. An accelerometer records the movement of your device along the three axes of the coordinate system. The X-axis measures the movement of your device from side to side, the Y-axis measures the movement along the top and bottom (including gravity), and the Z-axis measures the movement forward and backward.

A gyroscope measures the rotation along the three axes of the device's coordinate system. It detects the exact measure of your phone's rotation in radians per second. Position sensors record the physical location of the device. They do this by identifying your phone's coordinates—taking the world around them as a frame of reference and its orientation in 3-dimensional space. Phones use them for navigation, detecting screen orientation, and much more. Examples of position sensors are proximity sensors, GPS, and magnetometers.

A magnetometer senses your phone's orientation according to the earth's magnetic field.

Examples of environmental sensors are ambient light sensors, thermometers, barometers, air-humidity sensors, etc. Ambient light sensors measure the intensity of light around the device. These sensors detect the changes in brightness of the surroundings and record their intensity.

Proximity sensors detect how close a certain object is to your phone. A quick example of this is your phone's display turning off when you pick up and answer a call. This helps save battery power and avoids accidental taps during phone calls. A Hall sensor is quite similar to a proximity sensor, except it detects changes in the magnetic fields around the device. When it senses a change in the magnetic field, it sends this data to the processor, turning off the phone's display.

This sensor is specifically used to detect the magnets in flip covers. In this example, proximity sensors work by measuring the distance between the screen and your ear, and when the distance equals a set value, it turns off the display before your ear touches the screen. Biometric sensors use physical attributes for identification and are typically used for security purposes. As physical features like fingerprints, irises, and faces are unique to a person, using them for identity authentication provides enhanced protection. Some of the biometric sensors are Fingerprint Scanners and Iris sensors. Atmospheric sensors detect several aspects of your device's surroundings like atmospheric pressure, ambient temperature, air humidity, etc. Atmospheric sensors include a Thermometer, Barometer, and Air humidity sensors of one embodiment.
