Protek by Webbertek

Thermal / Acoustic Insulation Blanket

PROTEK is a remarkable new composite material that has been developed for applications in the transportation and construction industries where light weight, extreme heat resistance and sound attenuating material is required to meet multiple safety standards. This proprietary formulation has dramatically superior sound attenuation, heat and fire resistance characteristics compared to all conventional materials at a fraction of the weight.

PROTEK vs Fiberglass

A video demonstration of PROTEK and Fiberglass taking on a flame

PROTEK Burn Test

In this video, Scot demonstrates a sleeve/glove made of Webbertek’s PROTEK material taking a direct torch flame for an extended period of time. Our PROTEK material does not smoke and Scot’s hand is free of burns.

Fiberglass Burn Test

In this video, we demonstrate a piece of fiberglass taking the same flame as the PROTEK material from the other video. Immediately, you’ll notice toxic smoke being emitted from the fiberglass.

PROTEK in the Aviation Industry

It was developed to replace the traditional use Fiberglass in aviation applications. Fiberglass is highly toxic when burnt, retains moisture and fiberglass dust is a known health hazard. Standard Fiberglass has little noise reduction ability. Capital Aviation has been promoting and installing PROTEK 5000 now for over 5 years.

Sound Suppression

The PROTEK 5000 consists of two piles of high density fabric surrounding a center ply of aluminum foil, Alloy AA, O Temper, 0.000275 Mil that together produces a blanket that will not burn, will not produce smoke, will not retain moisture, has high noise reduction capabilities and high thermal properties.

The blanket is approximately 1/4” thick in 4’x10’ sheets. The blanket is easy to cut to size with a box knife. The weight of the blanket is approximately 5 oz/sq. ft. The weight difference between Fiberglass and PROTEK 5000 depends on the existing insulation installed in the aircraft. The weight increase in a Cessna Caravan 208B was 18 pounds and in most jets you will see a reduction in weight by switching to PROTEK 5000.

PROTEK 5000 has been installed by Capital Aviation in over 25 aircraft. The make and models are Astra 1125, Cessna Caravan 208 and 208B, Citation 560XL, 650 and 750, Falcon 20, Falcon 900B, Falcon 2000, Gulfstream GIV, Phenom 300 and Westwind.

PROTEK 5000 requires a burn test apprival for each aircraft installation. The following burn test have been passed with exceptional results for the aircraft mentioned above:

FAA FAR 23.853 Appendix F, Part I for Part 23 & 25 aircraft. FAA FAR 25.853 Appendix F, Part VI for Part 25 aircraft. See ACES test Report.

The Mesa, AZ Embraer Service installed PROTEK 5000 in a Phenom 300 in July of 2014. The net weight gain was 39 pounds. Per the owner, the cockpit noise reduction was 9 to 11 dB (actual was 57 to 59 dB in the cockpit) and the cabin noise reduction was 4 to 6 dB. Before and after noise measurements were taken by the owner.

Capital Aviation recorded on a Cessna 185 a 46 dB noise differential with reading taken inside the cabin interior and outside at the engine while running statistically at over 90% power.

Test Results and Benefits

Boeing Sound Test Results

General Dynamics Sound Test Results

Superior Heat and Fire Resistance
PROTEK exceeds the requirements of not burning through when subjected to 2000 degrees F for 4 minutes as set forth by Federal Air Regulations, FAR 25.853, Appendix F, part 7, as well as FAR 25.856
Superior Sound Attentuatuion Qualities
This proprietary formulation has dramatically superior sound attenuation compared to all conventional materials at a fraction of the weight.
Virtually Smokeless
The material is made from all natural materials and produces basically no smoke when subjected to a flame.
Rugged Bio-degradable Construction
PROTEK is flexible, moldable and will hold up to abrasive conditions. This material is less than .187 inch thickness and weighs in at 5 ounces per sq/ft.. In it’s raw state, PROTEK will not support mildew or mold growth if it is subjected to moisture.
Less Expensive
In addition to the superior performance characteristics, this material is far less expensive than any alternative material that can only approach the minimum requirements of sound attenuation, or fire and heat resistance imposed by current industry safety standards.
