Isotherm Thermal Insulation Summer Benefits

The Isotherm Thermal Insulation is one of the best thermal insulation products for roofs and ceilings. The 145mm Isotherm will reduce the heat flow into the home by as much as 90% on a hot summer day. How this works is quite simple. On a hot summer day, your roof space becomes like an oven. The temperature in the roof space climbs as the sun continues to beat down on the roof.

This, in turn, makes the ceiling in the home very hot. In fact, we have measure ceiling temperatures in some homes at 54 degrees Celsius. However the internal walls we reading temperatures of 30.5 degrees Celsius. This means that in summer it is as though you have the underfloor heating on but above your head in summer when you most certainly don’t want it. This radiant heat will make the inside of your home feel like you are in an oven.

This is where most home owners switch to air conditioners just to try and feel some comfort. However, the fact of the matter is running an air conditioner is very expensive in South Africa. In fact, homes insulated with Isotherm Thermal insulation will most likely not run the Air Con as the home will be cool enough. Home owners who are running air conditioners will find a huge saving as the thermostat will not have to kick in as often. This is where the energy saving comes into play.

Isotherm Thermal Insulation Winter Benefits

As with summer in winter the reverse happens. On a cold day, the roof space will get very cold as the cold air flows through the roof space. This, in turn, makes the ceiling very cold. As we know any warm air in the home will rise. As this warm air comes in contact with the cold ceiling space it will be drawn through the ceiling and lost to the roof space.

Most home owners using heaters or fire places will find that they need to sit right up close. In order to feel the benefit of the heating system. When the 145mm Isotherm has been installed this heat flow will not be lost to the roof space. In fact, the warm air will be retained in the home and in many cases will keep the entire home warm. Making life far more comfortable on freezing cold days.

As long as windows and doors are kept closed the heat generated in the home will be contained for hours. This makes the use of heating and fire places far more economical as the heating units can be used far less.

Eco-friendly Isotherm Insulation

Isotherm is regarded as one of the most eco-friendly insulation products on the market. Isotherm is manufactured from PET plastic bottles. These bottles are our Coke, Fanta bottles etc. In fact, this will be pollution in landfill sites for 450 years. Now converting this pollution into an energy saving Roof insulation is very innovative. So from pollution in the environment to saving energy that will help our environment is an absolute winner.

However, this gets better as ISOTHERM is itself recyclable. So the cycle continues. There is no other product on the market that I am aware of that can claim this. In fact, the fact that ISOTHERM is reducing the need for air conditioners is a great start. As first world countries like the USA have now become very strict on the types of air conditioners can be sold because of the damage that these units are having on the environment.

Isotherm is also manufactured in most major centers so the transport costs are reduced substantially. This, in turn, reduces the carbon foot print even more.

Loft Room Insulation

The 145mm Isotherm is our product of choice for loft room type insulation. Loft rooms are awesome in homes however they are like an oven in summer and a freezer in winter.

Loft Rooms that have been insulated are just as cool inside as any other home with Isotherm installed. What makes loft rooms so hot before the correct insulation is installed is the fact that ceiling space and side walls are all part of the roof structure. This means the hot ceiling boards or dry wall partitioning is very hot in summer and freezing cold in winter,

Roof Insulation Cape Town specializes in this type of installation and we only install the 145mm Isotherm in these applications. As this insulation has a very high tensile strength and a 30-year manufacturer guarantee. Visit our loft room page for more info on this.

Ceiling Insulation is Compulsory in All New Homes

All new homes including low-cost housing must now have SANS compliant ceiling insulation installed as of January 2013. In fact, this legislation is many years too late. Most 1st world countries have been insulating the roof space for many years. South Africa only realize recently that ESCOM was unable to supply the needs of consumers with electricity. This became a huge problem in 2015 when we were hit with load shedding. This ended up costing economy billions of rands as companies and workers got hit the hardest. Companies closed down with their losses and many workers lost their jobs.

If Ceiling and roof insulation had been made compulsory at least 10 or 15 years earlier we might have been able to avoid this. So what insulation must be installed on your ceiling. All products must be SANS compliant and achieve a specific R-value for the regions as set out by the legislation.

  • Western Cape Region must install the 145mm Isotherm as this will achieve the recommended R-value 3.70. The 145mm Isotherm is one of the most popular products that we install. in fact, this is because the Isotherm is Eco-friendly and people friendly.
  • Johannesburg region must install the 145mm Isotherm as this will also achieve the recommended R-value 3.70.
  • Pretoria and the Midrand must also install the 145mm Isotherm as they also need to achieve the R-value 3.70
  • KZN region must install the 100mm Isotherm Insulation as this will achieve the R-value for this region.

We have branches in these major centers so we can meet your Thermal Insulation needs. A cooler home in summer and a warmer home in winter is a happy home. Read our specifications page to get more info as well as the SANS legislation.

How Does Isotherm Save Money on Energy

You will never find an industrial manufacturing plant that uses energy for heating such as oil refineries sugar mills and most food manufacturing plants not being insulated. This is because they would never run at a profit. In fact, these industrial plants like ALUSAF will use more electricity than some medium sized towns. Now imagine what this would cost in lost revenue as a result of wasted money on energy. Some oil refineries spend millions of rands on insulation per year.

In fact, these industrial plants like ALUSAF will use more electricity than some medium sized towns. Now imagine what this would cost in lost revenue as a result of wasted money on energy. Some oil refineries spend millions of rands on insulation per year.

Your home is no different and most home owners are desperate to save money wherever possible. A home insulated with ISOTHERM will use far less energy as the home will be warmer in winter and cooler in summer. In fact if heating and cooling are used the settings can be turned down as the cooler air and the warmer air will be retained.

It has been estimated that home owners who have the correct insulation installed in their homes will use far less energy. And that the ISOTHERM cost should be recovered in as little as three years. In fact giving home owners many more years of energy saving and comfort. The 145mm Isotherm is a perfect example of how thermal insulation will save you energy keeping your hard earned cash in your pocket.

How Must Isotherm Be Installed

The Isotherm must be installed flat on the ceiling. In fact, all roof insulation products in homes must be installed flat on the ceiling. The reason for this is simple you do not want to cool down your roof space. Rather you want to cool down the inside of your home. If your Isotherm Installer fits the roof insulation following the pitch your roof space would be cool. You would still have to run an air conditioner to be comfortable.

In winter your home would be freezing cold as all the warm air created in the home will rise and be pulled into the cold roof space. So remember the insulation must be flat on the ceiling. In fact, we often get called out to homes where they have had insulation installed by either the Gumtree gang or some local handy man to see why the insulation is not working. On inspection, in most cases, the insulation is under spec or rolled over the beams. This will, in fact, make the home hotter in summer and colder in winter. The reason for this is the air pockets under the thermal insulation.

Acoustic Benefits of Isotherm

The Isotherm insulation has great acoustic properties when installing the 145mm Isotherm. This insulation will reduce the effect of noise pollution in the home. In fact, the roof space is where the biggest percentage of noise will enter the home. However, to sound proof the home we recommend two or three layers.

This will solve the noise levels coming through the roof. However, there are other factors to take into account. Such as windows doors etc. What we recommend for home owners who have serious noise pollution problems is as follows.

  • Insulate the roof space with two or three layers of 145mm Isotherm insulation.
  • Install heavy grade curtaining. In fact, this will not be commercially bought. They will have to be made up for your requirements. A high-density curtain fabric with maybe two layers of curtain lining at the back.
  • Be sure to seal all windows and doors. If your windows and doors leak air you need to seal them.
  • Finally and this is the more expensive option if your windows and doors are old and can’t be sealed consider fitting double glazed windows. However, the best for sound is the PVC window frames.

  Down Light Hazards With Roof Insulation

This is simple, never cover a down light with insulation. Always cut a breathing hole around the down light. Please note this is not because the insulation might burn. Isotherm will not burn as it will not sustain a flame. The problem is not insulation rather the down lights and how they are fitted.

Remember the older 40 and watts down light will reach temperatures of 270 to 350 degrees. This is hot enough to cook a meal on. When down lights are installed the electrician would mark them out and drill the holes into the ceiling. At completion, a few of these down light holes are either through a baton or under a main beam. Unfortunately these cant be moved as any visitor in the home would notice the spacing immediately.

Also be aware of old boxes leaves falling of the trees around the home very often end up in the roof space. If these leaves are over the down lights this could be a disaster. At least insulation will reduce the potential for the spread of flames in the roof.
