The Importance of a Radiant Barrier
Radiant heat will travel extremely fast until it is either reflected or absorbed. If you live in a hot climate, your roof can absorb heat from the sun – this causes your home to heat up to unbearable levels which will require you to use your air conditioning unit to expel this uncomfortable heat.
A radiant barrier will help to stop this radiant heat from entering the house. It actually reflects the heat back out before it is absorbed by the insulation in your attic. This can help you to save money with your energy bills as you do not have to pay to get rid of the heat because you have prevented it from entering the house altogether. Win-win, right?
So, how does it work in a colder climate or in the winter? One of the basic principles of temperature is that heat is always transferred from warm to cold. This means that when you are heating your home up in the winter, the heat is moving from the warm interior of your house to the cold outside.
The way houses are built is designed to reduce the amount of heat that is lost through the walls, but the attic can pose different problems altogether. While most walls have an inner and outer layer of insulation, roofs usually only have that barrier on the inside.
This can prove to be ineffective because the air moves around inside the inner insulation and, therefore, you’re actually losing the heat that you’re attempting to generate in cooler temperatures.
Installing a radiant barrier can help to minimize these problems by reducing the amount of heat lost and by reducing the amount of air moving around in the inner insulation of your attic.
You can place the radiant barrier across the insulation you already have in your attic and it will work to keep the heat inside the house where it belongs. This will help you to reduce the energy costs of heating your home.
A radiant barrier is similar to a windbreaker in that it stops the cold air from the attic from mixing with the warm air which is near the ceiling, thus reducing the loop of air which is continuously moving through the insulation.
One important point to note, however, when installing a radiant barrier in a cold climate is to make sure that you choose one that is perforated (breathable) in order to allow any and all moisture to escape.
If moisture cannot pass through the barrier, it could cause mold, bacteria, and dampness – all are enemies to an attic or inside a wall. A radiant barrier will help you to keep your home warm in the winter and cool in the summer and will reduce your energy bills.
Types of Radiant Barriers
Attic Radiant Barrier
One of the most important aspects to think about when building a home is insulation. It provides a more comfortable setting and will help to prevent too much heat from leaving the house when it is cold outside and too much heat from entering the house when it is hot outside.
The attic is the place where most of the heat can enter or leave the house. This is one area of the house that does not have insulation built-in, as it does in the walls, for example. An attic radiant barrier can prevent your house from becoming too hot in the summer and too cold in the winter.
Not only can this make your home more comfortable, but it can also dramatically reduce the amount you need to spend on cooling and heating your home.
Having an attic radiant barrier can increase the amount of heat in the attic during cold weather and it can have the opposite effect in the summer. In some homes, there has been a reduction in energy costs due to an attic radiant barrier of up to 40 percent; however, the average reductions would be more likely to be around 25 to 30 percent, but it greatly depends on the size of the home.
This is because, theoretically, you will not need to spend as much on heating your home as you will find that the heat is staying in the house where it belongs and is not escaping through the attic. In the summer, when it is hot outside, the attic radiant barrier will prevent excess heat from entering the home through the attic; therefore, you will not have to spend as much money on trying to cool your home down.
There are different types of attic radiant barriers available. You should know the various types and the difference between them before deciding which one is best to install in your own attic. An attic radiant barrier may be called anything from reflective foil insulation, attic heat barrier, aluminum foil insulation, reflective foil or radiant barriers.
There are three main types available: two-sided perforated, two-sided nonperforated and one-sided with bubble wrap. It is always better to purchase a perforated (breathable) attic radiant barrier so that you can let any excess moisture pass through.
A build-up of moisture under the radiant barrier could cause damp patches and mold in your attic – a problem you really want to avoid. By installing an attic radiant barrier, you will be reducing your costs and making sure your home is that bit more comfortable.
Radiant Barrier Blankets
In the winter, there is nothing nicer than getting into a warm bed which has been heated up. But the costs of using electric blankets and heated mattresses are inefficient to say in the least.
With the trend for reducing energy costs being so prominent now, is there any other cheaper alternative? You may not have heard of them but radiant barrier blankets are a great way to keep heat in without using any energy.
Made from similar technology as attic radiant barriers and radiant barrier curtains, these reflective blankets are a great way to make your bed cozier and more comfortable without the need for an electric blanket or heated mattress.
You may have seen emergency blankets before which are used to keep accident victims warm or for those suffering from hypothermia. Well, radiant barrier blankets are similar. They are made from polyethylene which is a soft material that is perfect for your bed as it is comfortable, warm and cozy.
These blankets are available in a variety of sizes to suit any size bed. You can even wash them in the washing machine making them a perfect way to keep your bed warm in the winter.
The aluminized side should be placed facing downwards on top of your top sheet as it reflects 95 percent of your body heat back towards you. The fact that radiant barrier blankets do not use any electricity means that you can keep warm all night long.
Many people are reluctant to keep their electric blankets on while they sleep as they are afraid that it could be dangerous and, because of this, some people can wake up feeling cold during the middle of the night. With a radiant barrier blanket, this problem is avoided. They are marvelous at keeping the heat all night long using your own body heat.
So, for an energy-efficient way to keep you warm all winter long, a radiant barrier blanket is an excellent choice. They are made with breathable fabric which will keep you warm and cozy the whole night through.
You will not only be more comfortable all night long, but you will be increasing your energy efficiency (and lowering your energy costs) as you will be able to turn the temperature of the house down too.
Radiant Barrier Curtains
With energy costs rising all the time, more and more people are looking for ways to reduce their energy bills. Heat can escape through a house if it is not insulated properly, but it can also escape through windows that are not double-glazed or which have loose or cracked old frames.
Some homes have older style windows and in the winter they can let in draughts of cold air. This can be felt as you move closer to the window. Naturally, this reduces the amount of heat in a room and may require you to increase the heating to try and warm up the room.
This could then end up costing you more money by increasing the amount of energy you are using. The ideal solution would be to replace the windows, but what if this is too expensive for you? There is something else you can do that is much more cost-effective and still provides you with the same solution: buy some radiant barrier curtains.
You might be surprised to realize how much heat is actually lost through windows that are not properly fitted or which are cracked. If you have your heating on and your home feels warm, then you should feel around the windows to see if you can feel any cold air.
If you can, then you know there is a leak somewhere. There are many different types of radiant barrier curtains available which can help you to prevent heat from leaving your house through the windows in the winter and prevent heat from entering your home in the summer.
The fabric used for these radiant barrier curtains is not bulky as you would expect but is thin and lightweight and ends up doing a remarkable job at reducing your energy use. Radiant barrier curtains can block the heat on both sides, plus they can provide shade from the sun.
They can be made to look aesthetically pleasing with a light-colored fabric on one side and the radiant barrier fabric on the other side. ou can also buy this fabric to line your existing curtains which will give you the same benefit while you still keep the curtains that you love.
The difference between radiant barrier curtains and blackout curtains is that blackout curtains block the light and absorb heat making them less energy efficient. Radiant barrier curtains will block the heat while still allowing light to pass through.
Another benefit to these curtains is that they are breathable too which will prevent your room from becoming stuffy. If you want to increase your energy efficiency but cannot afford new, expensive windows, then try some radiant barrier curtains and see the difference.
Radiant Barrier Foil
One of the most popular ways to save money on your heating bills is to install a radiant barrier in your home. Radiant barrier foil is one of the leading materials which are used for this.
A radiant barrier can reduce the heat which enters your home from outside in the summer, and it can also reduce the amount of heat that leaves your home in the winter. It can be placed directly on top of the traditional insulation to give even more effective insulation in your home.
Fiberglass is a material that is highly reflective and can be used to insulate attics, but its uses can be limited, especially in areas where moisture is prevalent.
Radiant barrier foil is available now and it can work in much the same way as fiberglass; however, where fiberglass fails, radiant barrier foil succeeds. It can slow down the transfer of heat from warm to cool areas by absorbing the heat before it escapes and reflecting it back the way it came.
There are three main types of radiant barrier foil that you can choose from. These are two-sided non-perforated, two-sided micro-perforated and two-sided with bubble wrap. One of the best types to choose is radiant barrier foil which is perforated (breathable) in order to let any moisture escape. This can reduce any damp or mold which could result if any moisture were to build up.
Radiant barrier foil usually comes on a roll and it can be laid out over the existing insulation or stapled onto the bottom of the rafters. To make sure that you are not trapping moisture if you place the foil directly on top of the existing insulation, the perforated radiant barrier foil works best. Unless you are an experienced DIY’er, then it is advisable to get it installed by a professional due to the dangers which could occur.
If you want to do your bit for the environment and help to increase your energy efficiency, then a radiant barrier can be the answer. Radiant barrier foil will help you to reduce the amount you spend on heating in the winter and will reduce the amount you need to spend cooling down your house in the summer.
It will make you feel more comfortable as it will keep the temperature of your home at the optimum temperature all year round, regardless of the season.
Radiant Barrier Insulation
To effectively reduce your energy bills, you may want to consider installing radiant barrier insulation in your attic. Radiant barrier insulation has become a popular choice of insulation in new build homes and it is used there in the walls and under the concrete to increase the energy efficiency of the house.
But for existing homes, radiant barrier insulation can be bought and installed in areas such as the attic to help decrease the amount of heat which is lost; therefore, you’re reducing the amount you need to spend on heating your home.
It will also help to reduce the amount of heat that the house absorbs from the sun in the summer, which will reduce the amount you need to spend on the air conditioning or electric fans. It has been said that some homes can reduce their energy bills by between 25 and 35 percent by using radiant barrier insulation.
One of the most popular materials for radiant barrier insulation is aluminum. This material is much more effective at reflecting heat than traditional forms of insulation such as Styrofoam, fiberglass or cellulose.
It can help you to keep the heat in during the winter by reflecting the heat generated in the house back inside before it has a chance to escape out into the cold. In the summer when you want it to be cooler, it can reflect heat from the sun back out on to the roof before it has the chance to enter the house. This will help you to maintain a comfortable temperature in the home throughout the year.
If you decide to install radiant barrier insulation in your attic, then it would be advisable to place it directly on top of your existing insulation. The material will either be one or two-sided, but it is important that the reflective side of the radiant barrier insulation is facing into the open air.
Installing radiant barrier insulation yourself can be a tricky job, so make sure you have a complete set of instructions to follow and, ideally, another set of hands to assist you. It is not necessary to staple the insulation sheets down but rather lay the edges of each sheet over the last.
You should make sure that the radiant barrier insulation is not touching the old insulation. There should be a clear space between each one in order to make sure you have a dead space of air between them. Otherwise, this could have the reverse effect to what you desire. You could find that heat is absorbed into the house in the summer and absorbed from the house in the winter, something you do not want.
Overall, if you install radiant barriers correctly, you should see immediate results and a long-term reduction on your overall energy bills.
