Does Radiant Barrier Works?
A Radiant Barrier main purpose is to avoid the heat transfer from the outside to the inside of
the house. It reduces energy costs. Most of the people use it in sunny weathers, but there are
people that use it for cold weathers too. In hot climates, radiant Barrier is more effective
because it can reduce cooling costs from 5% to 10%, allowing customers to have a smaller air
conditioning. This really good to save money, but in cool climates, it is more cost-effective to
install other systems such as heaters, fireplaces or thermal insulation. This is why the radiant
barrier insulation has become very popular these days.
A radiant barrier insulation is the perfect solution to both cool the house during the summer
and keeps it warm during the winter. It can be installed under concrete in new build homes.
For existing homes, the most common process is to install it in the attic to increase the energy
efficiency. Radiant Barriers depend on the good installation to work properly. So it is important that the
user hire a certified installer. If you choose to install it by yourself, you should fully read the
instructions. Also, you should research about other radiant barriers.
Once the radiant barrier is installed, it should reduce the heat immediately. Some others last a
little longer to work. It will also depend on the material that is made from. It is not the same
to have a heavy-duty than an aluminum, or even than Styrofoam, fiberglass or cellulose. Also
depends if the radiant barrier is double-sided or reinforced.
This is where we arrive at the main types of radiant barriers:
- Two-sided perforated
- Two-sided non-perforated
- One-sided with bubble wrap
Every attic is different and so the types of radiant barriers. The most important thing is to
avoid problems like build-up moisture that causes damp patches and mold. These kinds of
problems can cost you a lot of money.
Other types of radiant barriers are:
- Tensile strength
- The thickness of 5 mills
- Woven polyethylene material
- Mullen Burst Strength
Does an Attic Radiant Barrier Works?
It is really common to install attic radiant barriers because they are the most efficient ones.
Through the attic enter a lot of heat during the summer, it also leaves a lot of heat during the
winter. So, installing a radiant barrier in the attic allows avoiding the heating from entering
the house during summers while during the winter it will keep the heat inside the house.
The most common reason why users prefer to purchase a radiant barrier because it is really
cost-effective. It will help to reduce the energy costs. Either during summer or winter.
Insulation is perfect to maintain a nice ambiance inside the house during the hardest
Depending on where you live, the energy costs can be reduced up to 40 percent, which is
really helpful to save money. It not only depends on where the house is located, it will also
depend on how it was installed the radiant barrier and also on the size of the house.
How to Install Radiant Barrier Insulation
It is preferable to hire a certified technician to install Radiant Barrier because this will
determine its good performance. Installing this product in the house will depend on many
factors such as how big is the house; if it is new build or an existing one; if the attic has items
inside of it; how tall is the attic; etc.
There are different types of houses and climates, so there are different types of radiant barrier
1. Over the Insulation: this is the perfect method for warm and mixed climates. It is
perfect for houses that are located in the southern half of the USA. The easiest one
method of all, that can also work for other climates. It is one of the most used and
versatile methods of all. consists inlay the foil over existing insulation, maintaining
the heat during winter and also reflecting it to outside during the summer. Placed on
the attic floor, will make the insulation work better. It will create a green energy
barrier in the attic, which is really cool because it will minimize the airflow within the
insulation. Another awesome effect of this method is that reduces the radiant heat loss
or gain from the attic.
2. Staple up: this installation is designed for wide open attics, those ones that have
objects stored inside them. It will also work for those attics that have ductwork. It is
perfect for warm or hot climates only because it will help to reduce the summer heat
gain. This method consists in staple the radiant barrier foil all across the bottom of the
rafters, in a horizontal way. It is important to cover as much as the user can in order to
take advantage of the whole space. The benefits of this method are: cooling the attic,
gives storage space in the attic floor, and gives a better efficiency.
3. Flat top: this method is highly recommended for high-pitch attics and hard-to-reach
attics. You don’t have to foil the top of your attic because with this method the heat
will be reflected so good that you will reduce your energy costs. Creating a false
ceiling with the radiant barrier is the main purpose of this method, this will act as a
surface that will hold the foil in the top part of the attic. It is very suitable for hot
4. Hybrid installation: if you live in a mixed climate, this is the combination of the two
firsts methods. It combines “over the insulation” and “staple up” in order to increase
the energy efficiency. It consists in installing the radiant barrier foil over the existing
insulation on the floor and stapling it up in different areas of the attic. It is not
necessary to do both installations in order to see a change, but it helps to improve the
results. It can only be used if you don’t have items stored in your attic because
otherwise, you will not be able to make the “over the insulation”.
For each type of installation, you will need some tools in order to make the process possible
and safe. You will need a staple gun, a utility knife or box cutter, and measuring tape for
cutting and measuring the foil. The safe tools you will need to protect yourself are safety
glasses, dust mask, and gloves. There are also some optional tools to ease the process even
more like a ladder, a shop light, and a dowel or nail point.
Radiant Barrier Roof Underlayment
This is a process of installation of the radiant barrier. It is used in non-waterproof roofing
systems. So, it is important to first know the differences between the perforated and the solid
products. The perforated product is not a vapor barrier while the solid product is a vapor
barrier. Why is this important? Because the moisture is a problem you have to handle
depending on the type of roofing system you have at your house. The vapor barrier will not
allow the moisture to pass through. The roof ad foil product has millions of tiny pinholes that will allow moisture in its vapor form to pass through but it still has an excellent barrier against water in its liquid form. The solid product without the pinholes is not perforated so it will stop moisture from passing
through. In most roofing system it is necessary to have one vapor barrier that will allow the moisture
to dry either to the inside or to the outside. It is better to use a vapor barrier as an
underlayment and use the solid product (non-perforated radiant barrier) above it.
Radiant Barrier Cost
The most asked question when it comes to radiant barriers is how much it costs? This is a really good question because there are several factors that influence this cost. It will depend on your needs, the house you have, how big is your attic, where do you live, etc. So, basically, it is up to the user to find out how much it will cost from them its radiant barrier. The information you need to make an informed decision when shopping is the fire rating, the tensile strength, the perm rating and the warranty. Most radiant barriers look alike on the internet but not all are created equal. The installation is also very important to know how much it will cost: it will depend if you install it yourself or if you hire a certified technician to do it. The product needs to be installed with a correct overlap to achieve optimal results. It is important that if you choose to hire someone, make sure that it has employee’s insurance because otherwise if they get hurt you will have to pay for everything. In the end, the installation is an inversion that will give you the return on your investment because it will reduce your energy costs while it will maintain your home either warm during winter or cool during summer. When choosing a radiant barrier, it is important to know if you want to reduce the heat from entering into your house for hot or warm climates, or if you want to maintain the heat inside the house for cold climates. Every person’s need is unique and different, such as every type of radiant barrier. They may seem very similar but they aren’t. It is also important to research which is the best type of installation depending on the type of attic you have and also if you live in a cold or hot climate.
