Isotherm Applications

This insulation is very popular as the insulation is pleasant to touch. In fact, this is mostly because this Insulation is dust free allergy free and itch free. This makes the insulation a pleasure to use as there is no itch factor. As the Insulation is manufactured from PET bottles. 

Isotherm Roof Insulation

This insulation is perfect for Roofing Insulation. In fact, the 145mm Isotherm is SANS compliant for the entire Western Cape, Johannesburg and Pretoria. This Roof Insulation product is available in a number of thicknesses. So for the DIY homeowner, it is ideal as the insulation comes in two widths 750mm wide as well as 1200mm wide. The 750mm wide rolls are perfect for tiled roofs.

So for the DIY homeowner, it is ideal as the insulation comes in two widths 750mm wide as well as 1200mm wide. This 750mm wide roll is perfect for tiled roofs. In fact, this way DIY installers are forced to install the insulation full width of the beams because the width is already pre-cut.

Isotherm Loft Room Insulation

The Polyester Type insulation is perfect for Loft Room Insulation. In fact, this insulation is our product of choice for Loft Room Insulation. The 30-year manufacturer guarantee means that the Loft Room will be cool for many years. Roof Insulation specializes in Loft Room Insulation. All Loft Room must have insulation installed on top of the ceiling as well as the sloped section and the side walls. This will make any Loft Room a pleasure to live in. In fact temperature of up to 12  degrees C.

Isotherm Sound Proofing Insulation

In fact, this insulation is not the best for soundproofing unless a number of layers are installed. The insulation does not have a very good NRC Noise Reduction Coefficient. This insulation will make a difference in sound reduction. However, the Aerolite 135mm has the best NRC 1.1. This would then be our insulation of choice for sound proofing.  

Isotherm Dry Wall Insulation

Polyester Insulation is ideal for drywall insulation. The American style wooden homes are well suited for this Roof Insulation product. In fact, homes that have Insulation installed in the exterior wall are far more energy efficient than homes that are built with brick. The brick wall will absorb heat in summer and lose heat in winter. Wooden homes are far more energy efficient as the insulation in the walls has thermal insulation properties that reduce heat flow.

Isotherm Summer Benefits

In summer the roof space of all homes is filled with the sun's radiant heat. As the day heats up so the heat in the roof space increases. This increase in heat becomes pressure in the roof space. If you can reach your ceiling space and touch this or take a temperature reading on a hot day you would be absolutely shocked at the heat. This heat of the ceiling is like underfloor heating however it is above your head in summer. This is not when you want to heat in your home.

So how will the Insulation remedy this problem? Very simply if the Roof Insulation is installed by Expert Insulation Installers the insulation will be fitted correctly. In fact, all ceiling insulation must be installed directly onto the ceiling surface from above. If any insulation is fitted over the beams or against the roof in a normal cavity space this will be a waste of money. All Roof Insulation types must be fitted directly onto the ceiling for the best benefit.

The Roof Insulation will reduce the heat flow from the roof space via the ceiling from entering the home. This will reduce the heat flow by as much as 90%. Making the home cooler in summer by as much as 5 to 8 degrees C on very hot days. This on its own will reduce the need for air conditioners. In effect saving money on cooling.

Isotherm Winter Benefits

In winter the roof space is the coldest part of any home. And in the Cape region where we have strong winds and driving rain, our roof spaces are even colder. This cold air makes the ceiling space much colder than any other part of the home. So any energy created in the home will naturally rise as all heat will do. This will intern be sucked out of the home into the freezing cold ceiling space.

Insulating your home with 145mm Isotherm will reduce this heat flow by as much as 90%. In homes where heating is being used almost 80% of this heat will be lost through the ceiling without roof insulation. Once the Polyester Insulation has been laid directly onto the ceiling space the home will be much warmer as the heat will be retained in the home. In homes where heating is being used the heat will warm up most of the home as the bulk of the heat will rise and shift throughout the home.

This makes the home far more comfortable and energy efficient. In fact, insulation will pay for itself in two or three years on energy saving alone. This will then give you life long comfort and energy saving with SANS Compliant Insulation.

Get The Best Out Of Your Isotherm

The Isotherm is the best investment for any homeowner. Let's look at some ways to help you get the absolute best out of your insulation. Not all homes have double glazed windows, this would be first prize. Let us look at homes that have air leaks, now this is a problem in winter. It is one thing having your Insulation installed but you don't want cold air coming into the home.

Try and seal all windows and doors from air leakage. Wooden windows must be revamped or us rubber seal to stop the cold air entering the home. Also, long door sealers can be fitted to the base of the doors to prevent cold air blowing into the home.

On very cold days if you have very heavy curtains that are great as they will act as an insulation against cold windows. Keep all window curtains drawn so that the warm air is not lost to the cold window.

Of course in summer if you are out close curtains in rooms where the sun will shine through to get the best results. When you get home open windows and allow a draft through the home. All unwanted heat will follow the path of least resistance and flow out of the home.

What is Isotherm Insulation?

The Isotherm insulation is a polyester insulation manufactured from PET plastic bottles. This product is a roof insulation product that can also be used inside walls such as loft rooms. 

In fact, as ceiling insulation this product is one of the most highly rated insulated products. The insulation is manufactured to the highest standards including SABS.

As we know insulation is not usually user-friendly. Most insulation types have a host of chemicals and side effects, This insulation product is perfect for any home. In fact, your two-year-old can play with this insulation. One of the best insulation for ceilings in SA.

Dust Free Allergy Free Insulation

In fact of all insulation products on the market, I don’t know of any that are as user-friendly. This product is dust free and allergy free for those that allergies. Many people today suffer from all type of allergies. This fact has made this insulation so popular.

Isotherm Roof Insulation is Eco-friendly

Manufactured from pollution that will affect the earth and ocean for many years. This insulation is regarded as one of the most Eco-friendly ceiling insulation products on the market. Soft smooth feel. There is no itch and no fuss with Polyester Insulation. Many insulation products claim to be eco-friendly but they have a host of chemicals in them. In fact, Isotherm itself can be recycled.

Loft Room Insulation

We specialize in Loft room insulation as it is a far more complex installation than regular ceiling insulation. The loft room space must have side walls as well as the roof space insulated. When insulating the side walls the insulation is wired to the main beams. Isotherm insulation is our product of choice for these applications because of the long lifespan of the product.

In fact, it is pointless just insulating the roof space of a loft room as the side walls are also very hot. Therefore the roof space, as well as side walls, must be insulated.

Isotherm 30-year Guarantee

In fact, because of the products used to manufacture this Insulation it has a 30-year manufacturer guarantee. Unlike most Insulation types and especially the blow in type paper insulation products with a very short Installed life span because of the fire retardant properties dissipating in a few short years.

Most manufacturers will give a 5 to 10-year guarantee as they find it difficult to achieve a stable Roof Insulation product that is still in place and has not shifted significantly with the wind as with finely shredded paper.

Will Isotherm Burn

In fact, this insulation will not burn as this roof insulation has a bb/1/2 fire rating. This means that the insulation will not sustain a flame. In fact, even if you put a blow torch to Isotherm it will still not be able to sustain a flame. This is what makes Isotherm such a safe insulation product. In fact in most cases even if an electrical wire is burning in the roof space the insulation will help reduce the risk of fire making the home safer.

Can Isotherm Help With Condensation?

In fact, condensation is a big problem in many of the older homes in the Cape Town area. It is a known fact that the Cape area with its strong winds and driving rain is very cold in winter. This is, unfortunately, where condensation starts to play a big role.

How can we reduce the impact of condensation in our homes? Firstly start with a thick layer of 145mm Isotherm laid flat on the ceiling. This will help reduce the cold air entering the home. Secondly, seal all windows from allowing cold air into the home. Thirdly install heavy curtains and make sure they are closed properly at night.

This will reduce the levels of condensation substantially in the home. Making the home warmer in winter and giving the family a much healthier home to live in.

What Will Happen If My Isotherm Gets Wet?

In fact, there is no problem as the insulation is manufactured from PET plastic bottles. If the insulation gets wet it will not get moldy and need to be replaced in most cases. Isotherm will not gain weight and give you a ceiling collapse as the insulation has no paper in the product. The first warm day the ceiling insulation will dry naturally.

Will this insulation lose its insulation properties after being wet? Absolutely not. In fact, for a short will that the water is in the little air pockets in the insulation, there will be a reduced R-value effect. However, as soon as the insulation is dry all will be back to normal. If you find that the piece that was drenched in the roof leak you may want to remove the wet piece of insulation and lay it down to dry in a warm place. Replace the Insulation in its original place after it is dry and all will be good as new.

Do Rats Nest In Isotherm

In all my years of installing roof insulation products, we have never seen the effects of rats nesting in the insulation. This could be due to the fact that the insulation has a very high tensile strength and also a high density. In fact, this insulation is almost impossible to tear along the length.

Most homes that we remove insulation because of rat infestation it is usually found in the finely shredded paper insulation products like cellulose fiber. In fact, we vacuum a lot of this insulation out of roofs with our industrial vacuum machine. At times we suck out entire rat nests sometimes with the little ones that were abandoned with the nest. This is never nice to see and when it happens it is out of our control as the nests are not always visible until the machine sucks them out. For more info on our vacuum service visit our roof vacuum page.
