Low-density polyethylene (LDPE) is a thermoplastic polymer made from the monomer ethylene, characterized by its low density and flexible structure. It is commonly used in various applications, including packaging films, plastic bags, containers, and insulation for electrical cables. LDPE is known for...
Duct board is a type of heating and air conditioning insulation made from fiberglass and foil. It's light, yet durable, so it...
Blown insulation, also called loose fill insulation, is commonly used to insulate existing structures that previously had no insulation, or where additional insulation is needed. It is made up of loose particles which are blown into anatticor into wall cavities, which are the spaces between the...
How Insulation Works Insulation provides a thermal-resistant barrier. The combination of dead air spaces and the product itself prevents the movement of heat and air through walls, roofs, and floors. Heat conduction is somewhat like sound. Sound does not travel directly to your ear. Instead, it...
Vapor Barrier: Vapor barriers are often recommended or even required in order to prevent interior moisture from migrating into the roof system, where it can saturate theabove-deck insulation. Vapor barriers reduce the risk of premature roofing failures by reducing condensation within the roof system,...
Vapor barrier: Next is thevapor barrier. This underlayment helps prevent the roof from developing condensation or moisture issues. Overlay board: The roofing professional will lay down an overlay board orcover boardnext, to support the torch down roofing membrane. Care must be taken to apply the...
out of the bottom edge of the roof. The shed ceiling needs a vapor barrier on the warm side of the rafters and should be as airtight as possible because the underside of the sheathing can get cold. Warm moist air from below meeting cold air will cause condensation and wet insulation. ...
insulationmoisture problems A lot of people have heard advice aboutvapor barriers and vapor retarders. Many of them have walked away confused. A big part of the problem, I think, is that they’ve been told what to do—”Put it on the warm-in-winter side,” or “Never use one”—b...
It’s crucial to clarify thatvapor barriers don’t cause moldwhen installed correctly without gaps or holes. Moisture becomes a problem only if the vapor barrier is improperly installed or in the wrong location, creating ideal conditions for mold growth. ...
A conformal coating is a protective film applied to a circuit board that creates a barrier between the contaminants and the board. It acts as an insulation layer and protects the PCB surface simultaneously. Some coatings have a hard texture, while others have a rubbery texture. The conformal co...
