Does foil in the attic work?
Radiant barriers are more effective in hot climates than in cool climates, especially when cooling air ducts are located in the attic. Some studies show that radiant barriers can reduce cooling costs 5% to 10% when used in a warm, sunny climate.
How much does AtticFoil help?
You want to lower the surface temperatures in your attic because these are what directly affect the heat gain inside your home. AtticFoil™ will reflect 97% of the radiant heat coming off your roof, which is normally then absorbed by your insulation and ultimately heats up your home.
Is reflective insulation effective?
Reflective insulation can block 95% of radiant heat and provides superior thermal performance. Reflective insulation reflects escaping heat back in the direction of your home's interior. By harnessing the loss it lowers your heating bills.
Will aluminum foil work as a radiant barrier?
Aluminum foil has the radiant barrier properties of high reflectivity and low emissivity. That means the foil reflects much of the roof's heat back upward. The low emissivity property of the foil reduces the amount of heat that the foil radiates on through to the attic insulation below.
Do Radiant Barriers Work
Is aluminum foil good for insulation?
Aluminum foil can be an effective insulating material because it doesn't radiate heat out into the environment. That's what makes it effective directly under a roof: although it will warm up through conduction from the shingles, it won't radiate that heat out into the attic space.
Does aluminum foil insulate cold?
It doesn't only keep the food warmer for longer, but also keep things cold. It acts as a barrier to oxygen and air which can transfer heat to cold or frozen food. The bottom line is it helps by maintaining the temperature of the food, be it warm or cold.
Is multi foil insulation any good?
Multifoil insulation is often carried out on new builds, but it can also be added to older properties. More energy efficient than many traditional types of insulation, it's easy to install and has a number of useful properties, such as: Vapour control – this stops the insulation from becoming damp, keeping it effective.

Radiant Barriers (Reflective Insulation)
Reflective, radiant-barrier insulation is usually made of aluminum foil with a variety of different backings, including plastic film and cardboard. This type of insulation is most effective in warmer climates, but can also be used for comfort and energy savings in cold weather.
Is spray foam better than radiant barrier?
Open-celled spray-in foam insulation is by far superior to a traditional radiant barrier which is a foil-like thing that you can either tack to the rafters or lay on the floor of your attic. Open-cell foam is also more expensive, but in my opinion an excellent investment.
Do attic blankets work?
An attic blanket is a good way to add insulation to a house's upper story. Heat rises and also seeks cold areas, and the blanket is intended to prevent much of a home's heat from escaping. Attic insulation is a good investment, as more than 40 percent of a house's heat escapes through the roof.
Is radiant barrier better than insulation?
But if you must decide between the two, there is likely a clear winner: the radiant barrier. It is more effective, will give you more energy savings, and will provide you with more reliable in-home comfort.
How can I reduce the heat in my attic?
Install electric ventilators and attic fans, which remove hot air from an attic. They have thermostats that turn the fan on at a recommended preset temperature of 100-110 degrees. Alternatively, install passive vents such as gable, soffit and ridge vents, which are openings in the roof that allow hot air to escape.
Is TechShield worth the money?
For most new construction projects, I recommend using TechShield® (or another brand). The products work well, the cost of upgrading from regular OSB decking to radiant barrier decking is pretty minimal and there is NO additional labor cost since the Techshield® is installed just like a regular OSB roof deck.
Does reflective insulation keep heat in?
Unlike mass insulation, reflective insulation is able to keep heat in and reflect heat away. Mass insulation material like fiberglass and foam merely slow down the transfer of heat; they do not reflect heat away, nor do they keep heat in. Reflective insulation has the ability to control the transfer of radiant heat.
Does foil insulation meet building regs?
Can multifoil insulation meet new build regulations on their own? No. There is no multifoil product that will meet current new-build regulations by itself – all will need to be used with additional insulation, for example PhotonFoil with 65mm PIR will achieve a U-value of 0.18 W/m2. K in a pitched roof.

"Regardless of the side, both sides do the same job cooking, freezing and storing food," Mike Mazza, marketing director for Reynolds Wrap explained to TODAY. The only time it does matter is if you specifically buy non-stick foil.
Which way does the foil go on insulation?
Proper Installation of Roof Insulation
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.
