Isotherm Roll Sizes
We have two Roll widths of Insulation available. A single-pack roll is 1200mm wide, so the single-pack Isotherm Price will be less than the twin-pack Isotherm Price because of the square-meter difference. On the other hand, twin-pack rolls consist of two 750mm wide Rolls in each pack. Therefore, the twin-pack Isotherm Insulation Price per package will be slightly higher. However, the overall Isotherm Price per square meter will still be identical.
Isotherm Single Pack
All the Isotherm single-pack rolls are 1200mm wide or 1.2 meters wide. Additionally, the products are available in several thicknesses, from 50mm to 145mm thick.
Isotherm Twin Pack
Isotherm Twin Packs are two rolls in one package. This is because homeowners and builders did not have to cut the Isotherm. So, the twin pack rolls consist of two rolls that are 750mm wide and packed side by side. As a result, the total width would be two rolls side by side, totalling 1500mm Wide.
How To Cut Isotherm Insulation
Isotherm cant is cut with a wood saw like other traditional roof insulation materials, such as polyester. This is one of the reasons why the twin packs or 750mm wide rolls are made. In most cases, tiled roofs will have beams between 600mm and 800mm, so installers can easily fit these rolls between the beams.
As Isotherm Installers and distributors, we found that this method substantially increased insulation loss. In addition, as mentioned earlier, our beam widths will vary from roof to roof. As a result, we will supply homeowners and builders with the easiest way to cut Isotherm.
We will tear the Insulation to fit each specific pair of beams. When split correctly, it will tear in a direct, straight line. As a result, wastage is far less if your beams are 600mm apart and the Insulation is 750mm wide, giving a loss of 150mm per row on a standard roll.
We recommend using the 1200mm wide rolls and cutting all lines before installation. Ideally, one would tear all insulation in the roof spa; ripping all the insulation to the trusses’ correct width would take 20 minutes or an average of an hour. As a result of the insulation being torn, there is far less waste. Additionally, installing The Isotherm Insulation means the sections will be no longer than 1200mm, making this far more accessible to handle than a full roll laid out.
We must lift the wiring, electrical cable, and alarm wire above the Insulation for safety. With full rolls, wiring can be a problem.
Isotherm Specifications
Make sure to get the best Isotherm Price by checking the specifications and making the right choice. All Isotherm prices change based on the thickness and density of some Insulation products.
Isotherm Thickness | Density | R-value | R-value Installed | Climate Zones |
| 145mm | 11.5Kg3 | 3.37 | 3.77 | 1 & 4 |
| 135mm | 11.5Kg3 | 3.14 | 3.54 | 2 & 6 |
| 100mm | 8.5Kg3 | Not Tested | Not Tested | |
| 75mm | 8.5Kg3 | Not Tested | Not Tested | |
| 50mm | 8.5Kg3 | Not Tested | Not Tested | |
| 40mm | 8.5Kg3 | Not Tested | Not Tested | |
From Port Elizabeth to Alexander Bay, the Entire Western Cape region must install Insulation with an R-value exceeding 3.70.
As a result, the 145mm Isotherm Insulation is SANS-compliant for these regions. However, please note that the 135mm Isotherm is not SANS-compliant for the area as the R-value is under 3.70.
To compete with Aerolite Insulation, which has a very high R-value of 135mm, Isotherm has had to develop 145mm insulation similar to Aerolite or just below.
Isotherm Insulation Benefits
- Isotherm Insulation is Dust-free and Allergy Free.
- Isotherm Insulation is soft and smooth to the touch with no itch or loose fibre.
- Cooler in summer.
- Warmer in winter.
- Save energy on heating and cooling.
- Improve indoor temperature by 4 – 8 degrees.
- Tests have shown that correctly insulated homes can cover insulation costs in three to four years based on energy savings alone.
Isotherm Applications
As a polyester type, Isotherm insulation can be used in many applications. We have clients who purchase Isotherm Insulation to make dog cushions. However, the insulation product has several applications in the home.
- Isotherm Roof Insulation: The Isotherm conforms with the SANS legislation for all regions in South Africa. The Western Cape region has been classified to install the 145mm Isotherm. With a required R-value of 3.70 for the Western Cape region, the 145mm Isotherm achieves an R-value of 3.76 with an installed R-value.
- Isotherm Flat Roof Insulation: Isotherm can be installed under the roof sheeting.
- Loft Room Insulation: Isotherm Insulation is ideal for loft rooms because of its high tensile strength. Installing it against the sidewalls and the roof space transforms the loft space into a comfortable area.
Eco-friendly Isotherm Insulation
Isotherm is a polyester roof insulation product manufactured from PET plastic bottles. We are all aware of plastic bottle pollution from 2ltr plastic Coke Fanta and all plastic bottles. The Insulation is produced with the PET fibres of the Cooldrin bottle. For this reason, Isotherm is regarded as one of the most eco-friendly insulation products on the market. Additionally, Isotherm Insulation is recyclable after its use. For the record, Isotherm Insulation has a 30-year manufacturer guarantee.
