For the purpose of using this attic barrier type material inside the wall, there is a perforated material in the radiant barrier format but care still is recommended to keep condensation from creating. This will reduce any heat flow, but in a cold claim, care must be practiced assuring there isn’t a collision of the vapor barrier and the wall assembly. It can be used as a barrier on exterior walls with ventilated airspace between the attic barrier material and the cladding, which will act as in a rainscreen. If that isn’t possible, attic barrier can be applied against the sheathing directly.Īttic barrier material isn’t just for attics though. At this position, both sides will have the needed airspace. The radiant attic barrier is best when installed as a barrier attic ceiling directly to the roof’s interior framing. Why? Because the reflective surface of the attic barrier would prevent heat from being absorbed and what may get absorbed couldn’t emit back as radiation. If the same material that is used as an attic barrier is made was placed between us and that window or the woodstove, we wouldn’t feel the cold or heat.
So, when we walk from the cold window to a source of heat, the radiant heat warms us. The reason we feel cold while standing next to the window on a winter’s day is because we radiate heat to the colder window. To explain how this attic energy barrier thermal-reflective insulation works, we offer the following example: The transfer radiant heat occurs sandwiched between objects that are at different temperatures, moving from hot temperature to cold temperature. One of the biggest benefits for contractors is the ease of installing the spray on versus the roll out and fasten of the original attic barrier material. While that type of attic barrier insulation was helpful in keeping homes cooler in the summer, improvements were found by using a spray on liquid foil attic paint barrier.
Homeowners could use it in conjunction with other types of attic insulation like a bat or blown-in insulation. In this manner, this highly reflective aluminum foil type of material was perpendicular to the sun’s UV rays. The application of the original radiant attic barrier came in rolls and was applied to the ceiling of the attic. An attic barrier is relatively new, yet not so new. No matter if it is winter and you’re trying to keep your house warm or summer and you’re trying to keep it cool, getting your home insulated is one of the best ways.
