The radiant barrier should be installed in a manner to minimize dust accumulation on the reflective surface. When the sun heats a roof, it's primarily the sun's radiant energy that makes the roof hot. Much of this heat travels by conduction through the roofing materials to the attic side of the roof. The hot roof material then radiates its gained heat energy onto the cooler attic surfaces, including the air ducts and the attic floor.
A radiant barrier reduces the radiant heat transfer from the underside of the roof to the other surfaces in the attic. A radiant barrier works best when it is perpendicular to the radiant energy striking it. Also, the greater the temperature difference between the sides of the radiant barrier material, the greater the benefits a radiant barrier can offer.
Radiant barriers are more effective in hot climates than in cool climates, especially when cooling air ducts are located in the attic. The reduced heat gain may even allow for a smaller air conditioning system. Floor heating systems have been around for centuries to not only keep floors warm but to help heat the cooler air near the floor caused by cold air sinking while hot air rises in a room. A radiant barrier used in conjunction with radiant floor heating can help to lock in the heat in the floor so that it doesn't escape down into a basement or the ground below.
Our reflective insulation is the ideal product for all radiant floor heating systems and serves as a vapor barrier to block moisture penetration from below. Reflective insulation is also an ideal solution for keeping floors warm and blocking heat loss through flooring even without the use of radiant floor heating systems. This in turn keeps the living spaces warmer further increasing the comfort of the living space and reducing heating costs associated with maintaining a consistent room temperature.
New Metal Walls open interior. Bubble insulation can also help block radiant heat in post frame building structures inhibiting dew point condensation problems. Our bubble insulation also does not provide a growth medium or nutritive value for fungus, insects, or rodents.
WHITE bubble reflective insulation is the ideal choice for insulating new concrete floors against loss of heat. It can be used in conjunction with, or without, radiant heat tubing to help keep floors warm. The foil side is faced downwards to eliminate the concrete from coming in contact with it which could cause the foil to corrode due to the alkaline in the fresh concrete.
The Reflective Insulation Manufacturers Association consulted a firm specializing in thermal performance to help explain how reflective insulation works in a concrete slab application. Below is a direct quote from this study:. Thermal efficiency calculations were used to generate an estimate for a typical case involving reduction in heat loss for a common concrete floor system.
The calculation is based on steady-state thermal conditions with an isothermal plane at the heating pipes and a plane between the gravel and the ground. The ground temperature was 55 degrees Fahrenheit, while the temperature of the heating pipes was degrees Fahrenheit.
The calculation assumes two inches of concrete R A reflective insulation material R The system R-value of R Reflective insulation is excellent as a basement wall insulator. It performs as a vapor retarder, resists fungus and mold, and also controls dew point problems.
R-Values are unaffected by a damp moisture basement environment unlike fiberglass insulation. Reflective insulation applications are only limited by your imagination.
Below are a few more installation applications. When installing on the attic floor, work from the outer most regions of the attic and work your way towards the middle ideally where the "roll caddy" is located. Cut the longest pieces of barrier as fits when laying out in long run sections of your attic. It will cut down time spend on cutting and positioning smaller pieces.
The resulting number is the linear feet of barrier you should cut to fit this space. This roll caddy design is an inexpensive option to help with measurement and cutting of the radiant barrier. It helps to lift and hold the roll of radiant barrier up at a workable height making it easier to measure and cut.
Make sure you inquire with your consultant about the advantages of Radiant Barrier in the Attic. You too, can have an energy efficient attic. Spray on radiant barrier is also an effective process and offers extra protection. This product will stop moisture transfer and save you considerable costs. The process includes spraying reflective paint to the underside of the roof decking.
There are many different types of sprays on the market and they do not all provide the exact protection. Therefore, it is important that consumers speak with a professional regarding the type of spray in the market that will reduce the reflection of heat.
Not all sprays are available to consumers; commercial companies maintain environmentally safe spray products that their staff is highly trained to use.
