If it is silent, then the inspector should not treatment, so I am guessing which they Assume the code prohibits it.
This was included to the 2012 IMC requiring the duct tape to get "mentioned" but isn't construed to indicate that it needs to be labeled on the encounter on the tape as is needed UL 181A or B as utilized on UL listed manufacturing unit flexable duct or UL shown factory rigid Fiberglas duct board.
The chemical formulation of calcium silicate is Ca2SiO4. This formula signifies the ratio of calcium, silicon, and oxygen in the compound. The components of calcium silicate is crucial in determining its Qualities and for use in numerous apps for example cement, insulation, and fireproofing.
Extremely wholesome and various health and fitness Gains. Some harmful traits could be connected, but only below sure situation for example an allergic response. A-
Ca2SiO4 incorporates a crystalline framework that may vary depending on the particular sort and composition on the compound.
You might want to simply just ask for a code portion from him as an alternative to heading above their head correct from the start. It's really a great deal easier to acknowledge I am Completely wrong to the contractor than to your contractor and my boss.
The tape is to stop air leaks and I am aware Washington State Vitality Code is going in that path with leaks in heat ducts.

Ca2SiO4 doesn't have a definite boiling stage since it decomposes in advance of achieving its boiling point. When Ca2SiO4 is heated, it undergoes a series of chemical reactions that result in the release of water as well as the development of calcium oxide and silica.
This type of duct system shall be created of sheet metal not under No. 26 gage thickness and shall be continual in the air-dealing with equipment or equipment on the air outlet and inlet terminals.
