Home Insulation for Roofs has been made compulsory as of January 2013 in South Africa. This has been brought about as a result of the energy crisis in South Africa. As Eskom battles to supply energy.
As electricity costs climb, it has become more popular. The energy consumption has risen, and unfortunately, Escom has not been able to keep up with the supply of energy needed. Therefore Homeowners are using heaters to warm up their homes in winter and cool down their homes in summer. It is essential to install the best insulation for your home to have a lifetime of home comfort and energy saving.
Benefits of Home Insulation
We must install Home Insulation with an R-value of 3.70 for Cape Town and the Johannesburg and Pretoria region.
What is Home Insulation?
Most importantly, there are several factors that one must take into account. Let us look at the types of Home Insulation for your home.
- Ceiling insulation
- Drywalling insulation
- underfloor insulation
Types of Home Insulation for Ceilings
We only cover the most effective home insulation products in this article. However, there are a few insulation products that are not worth a mention because of their inconsistency.
Some of the most important factors to take into account with all home insulation products are as follows.
Firstly the thermal insulation must be SANS compliant and tested. Secondly, a higher fire rating is always better. Finally, insulation with a high R-value will result in a more comfortable house.
The two most common fire ratings available in SA are:
- Non-combustible AA 1/1 | Aerolite Insulation | Knauf Ecose Insulation. Certified for Hospitals, Schools, Shopping malls and Churches. Any area with high volumes of people must instal class AA 1/1 insulation for safety.
- Combustible BB 1/2 | Isotherm Insulation | Polyester Insulation | Cellulose Insulation. We can install home insulation classified as combustible in homes. Please note that the insulation products specified as combustible will not quickly burn.
Think Pink Aerolite For Homes
Aerolite insulation is undoubtedly one of the most advanced home insulation products. The Aerolite insulation is non-combustible with a Fire rating of A/A 1/1. Consequently, Think Pink Aerolite is the only thermal insulation specified for Hospitals, Schools and Shopping malls. And the reason for this is the safety of the insulation with large crowds. This insulation is not only non-combustible but also reduces noise pollution and improves indoor temperature substantially. Aerolite Roof Insulation products are manufactured from the recycled glass as well as silica sand. Ideal for homes that have downlights.
- Improve indoor temperature 5-8 degrees in summer and winter
- Save energy on heating and cooling
- The insulation has a long lifespan
- Reduces noise pollution
- It does not support vermin
- Fire rating Non-combustible Class AA 1/1
- SABS approved
- It is a 5-star insulation
- Excellent thermal insulation properties R-value 3.78 when installed
- The Western Cape should install the 135 mm Aerolite.
- The acoustic performance of Aerolite is excellent.
- Aerolite is the most advanced insulation for homes.
- Aerolite Insulation is excellent for drywall partitioning.
Knauf Ecose Insulation
We import the Knauf Ecose Insulation from Europe. Similar to the Aerolite insulation, it has a class AA 1/1 fire rating. Most importantly, Knauf insulation is also high-grade thermal home insulation for ceilings. Accordingly, the Knauf Ecose Hospitals, Schools and Shopping malls are also insulated with Knauf Ecose insulation.
- An improved indoor temperature 5-8 degrees in summer and winter
- Reduce heating and cooling costs
- long lifespan
- Reduce noise pollution
- Fire rating AA 1/1 Non-combustible
- 5 Star insulation
Polyester Home Insulation
There are a few polyester insulation products on the market. Unfortunately, some of the polyester insulation products are not worth mentioning.
Unfortunately, Isotherm insulation has recently dropped the SABS rating. As a result, many homeowners are cautious about installing insulation.
- Improves indoor temperature 3-5 degrees
- Reduces cooling and heating costs
- Fire rating BB 1/2 combustible
- 3 Star rating
Another polyester insulation is similar to Isotherm Insulation; however, this product is SABS approved. Unfortunately, the Platinum Fibre insulation is only available in Gauteng.
- Improves indoor temperature 3-5 degrees.
- The heating and cooling costs will be reduced.
- SABS approved
- Fire rating B/B 1/2 combustible
- 4 Star rating
Unfortunately, cellulose is not a product we install; however, it has its place in the market. The cellulose is rated combustible. However, the biggest problem is water absorption of the paper insulation and smouldering in the event of a fire.
- A temperature improvement of 3 degrees
- Reduce cooling costs
- Fire rating BB 1/2 combustible
- 3 Star rating
Why Is Insulation For Homes Important
Home Insulation is one of the most critical factors in saving energy and helping to reduce the impact of global warming. Uninsulated homes will consume more power in a bid to stay warmer in winter and cooler in summer.
The fact is on snowy winters days; homeowners will be using either a fireplace or gas heating. Installing ceiling insulation in your home will reduce heat flow in or out of the home by as much as 90%. The reality of this fact is that the house will be more comfortable by 4 to 8 deg C. This will reduce the need for cooling and heating.
Since 2013 we must insulate all new homes with SANS compliant insulation. For this reason, a specific R-value of home insulation has is specified. In the Western Cape and Gauteng, we must install insulation, achieving 3.70 R-values. The main reason for the new SANS building legislation is to reduce our need for electricity. Because of this legislation, homeowners can save as much as 30% on energy bills. For that reason, Home Insulation will increase resale value and home comfort.
Cavity Wall Insulation
With regards to wall cavity insulation, there are two types that we are looking at in this article. Firstly the most popular is Cavitywall insulation used in office applications as well as Nutec homes. Secondly, the cavity wall insulation between brick and mortar homes.
Cavitybatt is one of the essential insulation products for drywall partitioning and soundproofing. We install Cavitylite insulation in all NUTEC or timber frame homes.
Without a doubt, the CavityBatt or Cavitylite is the most advanced home insulation product for walls. We will install the insulation on the outside walls as well as internal walls. In my opinion, homes with Cavitybatt or Cavitylite are more energy-efficient than homes with brick and mortar.
CavityBatt and Cavitylite:
Underfloor Home Insulation Products
We find Some homeowners wonder why it is essential to install insulation under the concrete slab or foundation? It is necessary to install insulation underfloor in cold areas or areas with water springs under the house. We lay high-density polystyrene or Isoboard XPS across the entire floor. We then cover the whole floor with the desired slab thickness. Significantly the floor insulation will block cold air from entering the house.
