Testing the Construction Tapes. Are They Effective or Not?
Almost everywhere that we see, construction based adhesive tapes are used. From doors and windows to the envelope and the ductwork, they are used in different materials and applications all around the world. Some of the examples of the most commonly used tapes are as follows:
However, the present-day tape products are at times possessed by phantoms from the past not long ago. The actuality of the tape-based technology ( even ten years ago from before was the kind where adhesives and solvents lost their adhesive based power, became a little breakable, deteriorated from the ultraviolet based mortification or wholly trimmed apart.
The solvents for different tapes of lower qualities might have VOCs that were extremely injurious to health. Using these tapes for construction fundamentally represented something like a gamble when it’s protected behind a dry or cladding wall.
With their frustration of the tapes not being entirely effective, brought destruction caused by the loss of energy, mold, and the process of filtration of the air.
So, what does the present day industry tell us today? How are the adhesive based tapes being used in different parts of the United States? And most fundamentally, how good have they been so far? Before answering all these questions, let us quickly observe some of the best tapes in the market.
• Rubber Tape: Assists in sealing electrical connections. The most commonly used.
• Curtain Tape: Mostly contains stiffening tapes, pleat tapes, string pocket tapes, etc.
• Garment Elastic Tape: Mostly used in the stitching of the garments.
• Mounting Tapes: The most reliable tapes for mounting different objects permanently.
Mettle Tape Testing:
We are witnessing a period of standards and advanced codes, the overall performance of the tape has been questioned a lot. As per the rule of the IBC (International Building Code), it demands different wall assemblies, as well as different inflammable materials for weather, to surpass the demands of the NFPA 285.
NFPA 285 influences the preference and usage of different flashing based products. If the tape is supposed to be pliable, it should always be identified with an Assessment Service Report as the surpassing demands of AC 148 (Acceptance measures for Flexible materials for flashing). The AC 148 assesses:
• Testing adhesions
• Increased aging
• Tensile power testing
• Water acceptance testing
• Testing in colder conditions
With improved performances in the energy sector requires it to be bonded in different buildings, there are a few manufacturers out there replying with top performance asserts for the tape. Some of these tapes which are widely used for testing are as follows:
To show these asserts, the reports of extra testing might contain ASTM E 331, which copies rain that the wall system and roof must oppose during the phase of construction where the product is completely revealed.
With respect to using the water spray at approximately 32MPH, a vacuum is further used on the backside of the wall/roof to oppress the failure. This process is chosen to regulate the perforation of the water and its acceptance in the curtain walls, doors, windows systems, and skylights.
For flashing based materials, the benchmark set for the AAMA 711 generates the performance under the subjection for increased lengths during the process of construction and observing the resistance to the weathering damage.
Acrylic based adhesives may proclaim to be certified from TAS 100 and to be approved under TAS 100, the high-performing panels and wind-driven test for rain is permanently bonded by acrylic based tapes that are revealed to 110 MPH. This type of analysis is usually crafted to check the properties of the water system.
