There are many advantages to having your home properly insulated with roof insulation products like fiberglass insulation or polyester insulation.
The most important advantages of insulation is that it gives a reduction in home temperatures. Whether it be hot or cold temperatures. The insulation keeps your home more consistent without the need of heaters and air cons.
Secondly, because your home temperature is more stable and you are putting less strain on heating and cooling devices, you can expect to save a lot of money on heating and cooling bills during peak season times. Peak seasons like mid summer and mid winter. Is when we all put a lot of strain on our fragile electricity infrastructure here in South Africa. This can be avoided by having your home properly insulated by professionals.
What exactly does insulation do?
Roof insulation stops the air from outside your home from entering in through your ceiling. Whether it is hot air in summer or cold air in winter. Without insulation as a barrier between your ceiling and roof area. You only have a thin piece of ceiling to stop the unwanted air from entering in your home.
Advantages of insulation for winter
When the inside of your home (specifically your rooms) are at different temperatures this tends to be a problem. What you will find is in the colder winter months. Your heating systems need to compensate for all the cold air moving in through your ceiling and into your home below. It takes a lot more energy to warm up a cold room in a house. So your electricity bill will increase astronomically.
If your home uses a central heating system. You will find that an uninsulated home will take much longer to warm up and reach a comfortable level. This is a problem because you will see your electricity bills will rise. As you use more energy to maintain a comfortable environment inside your home.
Advantages of insulation for summer
You will find a very similar problem in summer with an uninsulated home. The sun bakes on your roof from the outside, cause the inside of your roof to warm up dramatically. The heat that get built up inside your roof then starts getting forced inside your home through the thin ceiling.
When you have no insulation to block the heat from entering your ceiling. It can be very uncomfortable during the peak summer season making every room in your home unbearable to be in. Which leads to putting the air cons on and trying to cool the room down. Which again leads to higher electricity bills!
What are the advantages of insulation?
Think of roof insulation as a blocker. It blocks hot and cold air from moving into areas of your home that you don’t want it to be in. Keeping your indoor environment cozy in winter and most definitely cooler in summer. There are different types of insulation that is available for home owners to buy.
The preferred insulation by many people would be aerolite insulation. Which is a fiberglass based insulation and has been around the longest, and a polyester insulation called isotherm.
Many people in the last few years have been looking into eco-friendly insulation, and isotherm is just that. It contains no itchy fibers. In fact you could sleep with it like a duvet and you wouldn’t have any problems with chemicals or fiberglass. Polyester insulation is by far the most eco-friendly insulation we have on offer, with no chemical additives.
Roof insulation and climates
You must also take into consideration the climate of where your home is located. Depending on where you are situated. Your home could potentially need thicker roof insulation if you are located in an extremely hot climate or cold climate.
It is also important to not only judge the material by its thickness. Have a look at the R-value and density of the material as well. Very often you will find a wide variety of materials. That are all made the same thickness but they have completely different R-values. The denser the insulation and higher the R-value the product has, the better the insulation will be.
Types of insulation products available
Advantages of fiberglass insulation
Fiberglass is the most commonly used product today and has been around for the longest. Don’t confuse fiberglass with asbestos. If you are asking yourself the question, does aerolite contain asbestos? The answer is NO, aerolite does not contain asbestos. It is a man-made fiberglass insulation that has a good fire rating. You will find that aerolite has a life span of around 40 – 50 years. It will only really need to install it once, and it will continue to save you money thereafter.
Advantages of polyester insulation
Polyester is probably the second most commonly used product and slowly growing into the most used insulation. Here in South Africa there has been a massive switch between home-owners and insulation. More and more people going the eco-friendly polyester insulation route now days. There are quite a few different polyester brands on the market available for the consumer to choose from. Isotherm insulation has become the biggest polyester manufacturer here in South Africa. The advantages of insulation made from polyester are amazing. No itchy fibers or chemical additives and made from recycled plastic bottles that is good for the environment. Eco-friendly recycled polyester can be recycled again which is another good point for the product.
Advantages of cellulose fiber insulation
Cellulose fiber insulation, is also known as blow in insulation or loose fill insulation. Is another product here in South Africa that many people use. It is treated with chemicals to give it a fire retardant status and is made of recycled newspapers. Can cellulose fiber be recycled? The answer is no cellulose fiber cannot be recycled once it has been produced. As far as the insulating value is concerned. It doesn’t have a bad R-value. In fact it matches both aerolite and isotherm. The chemicals in cellulose insulation may be a bit of a concern for the average home-owner.
