Poly-Storm™ Testing Library for Residential Construction 

PowerPolymer Lightweight Thin EF-5 Resistant Doors for Residential Construction
 
Our unique storm shelter systems with Poly-Storm™ technology are designed to resist missile impacts and wind pressures generated by EF-5 tornados at multiple critical locations. Our Poly-Storm™ designs have passed test criteria in accordance with FEMA 320 / 361 and ICC 500 Standards through the Department of Homeland Security.
 
  • Doors, walls, roof, & anchors
  • Tested to withstand 250 mph ground wind-speed tornados

PowerPolymer EF-5 Tornado Resistant Walls for Residential Construction

In comparison to carbon fiber reinforced polymer wall systems (CFRP or CF/E), our Poly-Storm™ walls localize impacts and quickly transfer impact energies through an internal self-healing, resilient lock mechanism.  Consequently, while CFRP or CF/E wall systems dramatically fail after just one EF-5 impact, our Poly-Storm™ designs will protect you and your loved ones from otherwise cataclysmic certainty, impact after impact.  PowerPolymer's thin, inconspicuous and very affordable shelters can be masked as a home office, a bedroom closet, or even a classy entertainment room.

Triple-Threat Residential Protection against Extreme Seismic-Tornado-Moisture Events

Tri-Hazards Resistance for Seismic-Tornado Threats in accordance with ASCE-07, FEMA P695, and IBC 2018

Our unique fundamental inlay has been validated as a multi-hazards mitigation system in scenarios of combined high seismicity, tornado (EF-5), and moisture (flooding).

Wood-framed shear wall structures incorporated with our technology, see figures and below, can alleviate soft story collapse, reduce inter-story drift ratios, and reduce accelerations (and consequent non-structural damage) in accordance with ASCE-07, FEMA P695, and IBC 2018.

Our uniquely formulated energy dissipation mechanism circumvents limitations of current seismic standards for residential constructions, including issues related to vertical uplift, insufficient energy transfer, and inadequate racking strength (with and without openings).

In addition, our methodology reduces timber usage as well as limits the number of wood fasteners and hold-downs during construction and implementation of our system.

Our approach ascertains new seismic design response modification factors, R-factors, for enhanced ductility and newly calculated story-force distributions.

Our studies further indicate that moisture constants for diffusivity and absorption percentage may be directly controlled, and reduced, using our thermodynamic processing techniques. The result is less moisture absorption during storm periods and flooding. The combined seismic-tornado-moisture resistant design is illustrated below.

PowerPolymer’s Multi-Hazards Safe Room System

PowerPolymer’s multi-functional safe room design incorporates moisture resistance during high storm periods and flooding, near-field seismic resistance during intense ground shaking through vibration control, and tornado resistance during EF-5 rated missile strikes from debris during 250-mph ground wind speed tornados.

Seismic Protection for Residential Structures

Bi-axial seismic loading (lateral-gravity loading) Reinforced Concrete (R/C) Seismic Shear Walls

Our technique that engenders a unique distribution of chemical bonds has also been validated for residential concrete structures located in regions of high seismicity.  Specifically, bi-axially loaded reinforced concrete shear walls that had experienced substantial seismic damage were retrofitted using our unique PowerPolymer coating system.  Our extensive experimental testing has validated the ability of our system to stabilize crack propagation via a unique energy dissipation mechanism.

The outcome of our testing: lateral load resistance of shear walls, severely damaged where only 40% of strength capacity had remained, suddenly increased by 100% following a significant increase in ductility and confinement at the critical wall base.

Tornado Protection for Residential and Commercial Structures

Tornado Safe Room Design in accordance with FEMA 320 / 361 and ICC 500

PowerPolymer’s tornado safe room design includes a patent-protected inlay that can tremendously enhance the tornado building envelope in residential structures. 
See the wall and door test set-ups figures below, (a) and (b).

The thin inlay material, only approximately ¼ inch thick, has a unique chemical composition that has been fundamentally developed from basic science over the last 13 years (starting in 2008) and that allows the walls to withstand high-debris impacts generated by EF-5 rated 250 mph ground wind speed tornados. Our wind-borne debris impact tests were conducted at the National Wind Institute (NWI) at Texas Tech University and in accordance with FEMA 320 and 361, and ICC500 (International Code Council) standards, to meet both construction and testing criteria.

The inlay may be used to protect the wall and door elements of the storm room and is placed inconspicuously between the exterior plywood during construction. 
See images below.

In door panels, the inlay is placed inconspicuously between the exterior panel of a storm door (constructed using as thin as 18-guage steel) and an  embossed veneer. Compared to conventional steel door and expensive carbon-fiber construction options, our unique lightweight functional chemistry-driven design is less than one half the cost; and, unlike carbon-fiber systems, our system passes EF-5 impacts with flying colors.  See images below.

Ballistic & Blast Protection with Design-Efficiency Insulation

Tornado-Resistant and Energy-Efficient Commercial Tilt-Up Wall Constructions
(for commercial & military applications) 


Our innovative materials system may also be utilized in thin tilt-up wall constructions for large commercial applications as a thermal-mechanical multi-functional layer.

Applied in thin multi-layer the precast concrete systems, our design: (1) enhances debris-impact resistance; (2) reduces thermal bridging (R-value); and (3) increases flexural capacity in thin concrete wall systems.

Using our system, thin precast concrete sandwich panels (PCSP) are able to retain full-composite action while remaining thermally insulative, engendering high R-value and mechanical energy transferability, in lieu of relying on industry-standard often-times three-inch thick extruded polystyrene (XPS).

Our manufacturing processing is also streamlined for efficient fabrication. Due to its large shear resistance, our materials system eliminates the need for transverse reinforcement and eliminates the otherwise subsequent thermal bridging. By supplanting the XPS foam insulation used in typical sandwich panel construction, our insulation-mechanical system: (a) dissipates energy through interfacial mobility; and (b) improves the R-value to at least R-10 (hr-ft2 – o F/ Btu) for ½-in inlay, vs R-5 per inch for XPS and about R-4 per inch for EPS to reduce energy costs by 5% – 20%.  The image below shows debris-impact resistance from 250-mph ground wind speed tornados
