Reflective insulation systems consist essentially of aluminum foils together with a back - up substance. The most frequently used materials for reflective insulation are:
- Kraft paper
- Plastic film
- Polyethylene bubbles
- Cardboard
Usually reflective insulation systems operate by offering heat energy flow resistance. When heat flows in the downward direction, they work extremely well. For installation between roof rafters, floor joists, or wall studs, these types of insulation systems are generally recommended. They are installed in the same manner as isolation from battle and blanket.
Materials used for making reflective insulation consist of flanges which are meant to be stapled to wall studs or floor joists. Given that reflective insulation materials are good conductors of electricity, one must ensure that no direct contact is made with exposed electrical wiring.
Besides, for effective thermal performance, correct installation of reflective insulation is required. The operation of insulation is displayed in the above picture.4
Radiant Barrier Insulation:
A radiant barrier isolation system is a film layer facing an air space and is installed in a building’s envelope." In other words, “If a single reflective surface is used alone and faces an open space such as an attic, it is called a radiant barrier.” It is the reflective isolation system that is frequently used to permanently reduce energy costs.
These insulation systems operate by reflecting radiant heat energy. Due to changes in humidity, the performance of radiant barrier insulation systems containing pure aluminum form does not vary. Low emission and high reflection values are highly desirable in order to obtain effective radian results.
Applications:
-
Thermal insulation of the commercial and residential building.
-
To protect shipments carrying drugs and food items
-
For transportation and automotive purposes
