Does radiant barrier go up or down?
Research by the Florida Solar Energy Center (FSEC) found that radiant barriers work best when installed with foil-face down (towards the building interior) and applied under the roof sheathing.
Does moisture barrier go up or down?
#1 – Lay Down Moisture Barrier Experts say the plastic should be secured at a distance of about six inches up the wall.
Does radiant barrier need air space on both sides?
The problem here is that for a radiant barrier to work, it must have an air gap on one side or the other. If they staple this stuff to the underside of the rafters in an attic, it will greatly reduce heat gain in the attic, and the temperature will be about 20 degrees lower. That's because there's an air gap.
Does vapor barrier go on the warm side?
Vapor barrier materials are installed on the warm side of the insulation in a building assembly, as determined by climatic conditions. In warm climates, it will be on the exterior and in cold climates, it will be on the interior.
What Is Reflective Insulation?

Can you use insulation in a retrofit?
Foil insulation can be applied in both new and retrofit constructions.
Why should aluminum facings be facing toward the inside of the house?
Hi, Carol, The aluminum facing should always face toward the inside of the home (whether in a wall or ceiling) to prevent water vapor from passing through it. There’s just one exception to that rule, and it’s if the insulation is installed over another piece of insulation.
Why is paper vapor barrier used in insulation?
That’s because the paper contains a layer of asphalt adhesive which prevents water vapor from passing through it. If the insulation is installed with the paper vapor barrier facing away from the heated part of the home, moisture from humid inside air can condense and become trapped in the insulation during cold winter months.
Is foam pipe insulation better than fiberglass?
It’s better to use foam pipe insulation than standard fiberglass insulation on water pipes. It’s easier to install and has higher insulating qualities for the thickness. Make sure you get the right size for your pipes. Reply.
Can condensation be caused by insulation?
Depending on the climate where you live, it may or may not cause a condensation problem. Colder climates, like you have in Pennsylvania, will have more chance of condensation problems than a warm climate. Assuming the insulation isn’t too much trouble to get to, I would turn it over so the paper facing is toward the ceiling, or peel the facing off all together. If it is a lot of trouble to change it, feel under it during the winter and see if it feels damp. If it does you definitely need to fix it to prevent rot or mold.
Can you put fiberglass insulation over blown in insulation?
You can lay rolls or batts of fiberglass insulation over existing blown in insulation, but you need to use unfaced insulation to prevent moisture from being trapped between the layers. Since you’ve already purchased and installed faced insulation, your best bet is to peel the paper facing off the insulation you installed.
How To Install Reflective Insulation?
If a property is already completed and not insulated, it can still be insulated through a process known as retrofitting . In essence, retrofitting is a way to install insulation in the roof, walls and floors of a building after it has been built. The process is more tricky than installing foil insulation during the construction of a property, but can be undertaken if need be.
How To Install Foil Insulation On Walls?
This is because it is difficult to get into the plaster once it is set, without cutting through . As a matter of fact, if you install insulation during the construction phase, it actually speeds up the whole building process. This is because it protects the inside from rain, meaning work can carry on without bricking or cladwork being complete.
What Is Foil Insulation Used For?
Foil insulation is used as a means to maintain high levels of thermal efficiency within a property. The purpose of installing the foil insulation panel in your home or office is to ensure that internal temperatures stay at a comfortable level all year round, regardless of whatever volatility occurs in the outdoor climate.

Why is foil insulation called reflective insulation?
The reason it is sometimes referred to as reflective insulation is, because on hot days, the reflective surface of the insulation panels literally reflect the sun rays back out, stopping them from entering your property.
Why use foil insulation?
Basically, a foil insulation panel works to reduce the heat transfer effect that occurs during thermal radiation. The reflective surface acts as a barrier to reflect the heat from one side of the panel, preventing it from transferring to the other side.
Why do you need insulation during construction?
This is because it protects the inside from rain, meaning work can carry on without bricking or cladwork being complete.
How does radiant barrier insulation work?
RadiantGUARD® radiant barrier foil insulation installed in an attics can reduce attic temperatures by up to 30 degrees when stapled with a staple gun to the underside of roof rafters by REFLECTING up to 97% of the radiant heat that strikes its surface thereby reducing heat transfer from the attic to living spaces resulting in lower utility bills. This method also reduces the heat subject to attic mounted AC duct work thereby allowing them to work more efficiently.
Where to staple radiant barrier?
Staple the radiant barrier to all knew walls located in your attic space overlapping each piece by 2".
How effective is radiant barrier?
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. As long as there is at least a 3/4" air space on either side of the radiant barrier, the application will be effective at BLOCKING radiant heat. 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.
What is radiant barrier on counter?
The picture below shows a batten/counter batten system with a slate/tile material with a radiant barrier on top of the counter battens. The radiant barrier is installed on the top of the counter battens in non-watertight applications. This allows the radiant barrier to remain dry while also achieving the 3/4" air space requirement.
How to keep your attic cool?
Start early in the morning when your attic is at its coolest. Carry all of your radiant barrier and tools into the attic to avoid unnecessary trips to and fro. Keep plenty of water on hand and drink even if you don't think you're thirsty; especially in the summer months.
What are some examples of radiant barrier roofing?
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.
How much space between rafters?
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.
What is radiant foil insulation?
The radiant foil barrier reflects all that heat back into the air space between it and the roofing. When foil insulation is properly installed, the underside of the roof decking remains at or near the ambient temperature, even in full sun. This doesn't work, though, if you install the radiant barrier upside down – that is, ...
Where does foil go on a roof?
The foil then goes under the battens. For proper installation of roof insulation, you need to do it before the roofing goes on. If you want to add foil insulation to an existing roof, you can still do it by going into the attic and stapling it to the undersides of the roof rafters. If you do this, the shiny side of the insulation still goes up, ...
What goes on top of the moisture barrier?
The foil insulation goes on top of the moisture barrier, followed by the roof covering. If you use bubble foil or rigid foam insulation, it also goes on top of the moisture barrier. Remember that there has to be an air space between the foil and the roofing. Most metal corrugated roofing automatically provides this air space.
Why do you need foil insulation?
The Reason Why You Need Foil Insulation. When sunlight impinges directly on a metal roof, it drives the temperature of the metal as high as 180 degrees Fahrenheit. In the absence of a foil insulation barrier, the underside of the roof radiates all the heat directly into the attic. The attic overheats, the house becomes warmer ...
What happens if the shiny side of the barrier faces the roof?
If the shiny side of the barrier faces the roofing, hot air will circulate in the space between the rafters and naturally exit through the roof vent. This scheme works best if the house has a ridge vent that spans the length of the roof.
Does foam insulation board have a foil backing?
Foam insulation board also comes with a foil backing, and when the foil is just on one side of the board, you have a decision to make regarding its orientation. If you're wondering whether to put the foil side of foam insulation board shiny side in or out, consider whether you want to make the space inside warmer or cooler.
Does radiant barrier work upside down?
This doesn't work, though, if you install the radiant barrier upside down – that is, with the shiny side facing down. If you do that, the barrier absorbs the heat and radiates it into the attic instead of back toward the roof. A radiant barrier can reduce the temperature in the attic by as much as 30 degrees.
Where to install polyiso?
If there is aluminum foil on just one side of the polyiso, here's my advice: install the polyiso tight to the rim joist, with the shiny side facing toward the interior of the building.
How much air space does a foil need?
If you want it to serve as a radiant barrier, the foil must face an air space of at least 1/2".
How to keep a building warm?
To keep a building warm, you need something with R-value (insulation). The higher the R-value (and the lower the rate of air leakage), the better. As Dana explained, the foil facing on rigid foam has the effect of raising the R-value of an adjacent air space if there is an adjacent air space.
How does reflective insulation work?
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. When installed in a crawl space, our reflective insulation products will block up to 97% of the radiant heat loss that occurs through floors keeping floors warm and reducing cold drafts. 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.
How much heat does bubble insulation block?
Bubble insulation not only blocks 95-97% of the radiant heat striking its surface, it also provides the necessary thermal break to eliminate condensation problems in metal buildings.
What is white bubble insulation?
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 product is to be laid down with the FOIL side down towards the ground and WHITE side up over which the radiant heat tubing and fresh concrete are to be applied. 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.
What is the R value of white double bubble insulation?
WHITE Double Bubble insulation used in a concrete flooring application is stated to achieve an estimated R-Value of 1.1.
Is bubble insulation permeable?
