Any soffit vents will be beyond this wall plate. If you have gable walls exterior vertical side walls of roof , install in the same manner making sure to cut out material over any and all air vents to allow for air flow. Starting at one end of your attic, install our Ultima-FOIL breathable radiant barrier over across attic floor joists, plywood decking or existing insulation.
Continue covering the attic floor by overlapping each section of radiant barrier already rolled out by 2" inches. When laying the foil insulation, it is not necessary to make it lie smooth or flat. It is also not necessary to tape the seams. You can staple the barrier in place if you wish but it's not necessary. Staple the radiant barrier to all knew walls located in your attic space overlapping each piece by 2".
A great tip related to laying the radiant barrier directly on the attic floor is to tape an outline of any underlying decking pieces you use to walk on to access various storage areas or equipment in your attic. By outlining these decking pieces with a brightly colored tape, you, and contractors or repairmen who access your attic in the future, will easily be able to see where it's safe to walk eliminating the risk of stepping in the wrong place through the ceiling drywall.
Install unfaced mass insulation between rafters ensuring a minimum of 1" ventilation space between the mass insulation and the underside of the roof decking. Check with local codes to determine if you must maintain a larger air space. If necessary, you can install vent chutes or baffles to ensure the proper air flow channel.
Unroll and staple reflective insulation to the under side of the rafters. Install furring strips to the underside of the radiant barrier every 16" perpendicular to the rafters. In the above states, you can staple the FOIL Double Bubble insulation directly to the roof decking instead of installing to the underside of the rafters as indicated above. In this installation, you do not need to secure furring strips before attaching the drywall. Radiant barriers can be extremely effective at lowering radiant heat transfers when used in exterior siding applications but again, it MUST have an air space on at least one side of the radiant barrier for it to work.
In this application, a radiant barrier is installed like a typical house wrap yet before the siding is installed, you must attach 1 X 2 furring strips over the top of the radiant barrier to which to attach the siding. This creates the required air space for the radiant barrier to be effective. Starting at one end of your attic, install our Ultima-FOIL breathable radiant barrier across attic floor joists, plywood decking or existing insulation.
A radiant barrier can be very effective at BLOCKING radiant heat when installed in conjunction with roofing and siding material, however, the radiant barrier MUST be installed with an air space on at least one side of it.
For more information on why a radiant barrier must have an air space on one side of it to be effective, please see our What is Radiant Barrier page. Metal, tile, and slate roofing systems are examples of such roofing systems where a radiant barrier can be easily incorporated. Equally as important as the air space on a radiant barrier is the requirement that a radiant barrier remain clean and dry in any application.
The radiant barrier is installed on the top of the counter battens in non-watertight applications. If the roofing material is watertight, installing the radiant barrier on top of the felt with the batten on top of it would be sufficient.
Because a radiant barrier needs an air space on at least one side, installing it directly below felt and shingles will NOT allow the radiant barrier to block any radiant heat. Instead, the heat from the shingles and felt will conduct all the way through the barrier, into the attic, and eventually in the living spaces. If an asphalt shingle roof is being installed, you should install the radiant barrier to the underside of the roof decking or roof rafters in the attic space below.
Note: Our bubble insulation products are solid vapor barriers i. R-Values indicated below vary per installation method depending on the size of the air space surrounding the product and the direction of heat flow. Because of these variables, you can achieve several different R-Values with one basic product.
Most people are familiar with extreme heat found in attic, but there is secondary method of heat transfer into a building structure; through the walls. Radiant barriers installed as house wraps during new construction projects or bubble insulation retrofitted into wall systems can block a majority of the heat that transfers through the walls into living spaces.
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.
