Home Insulation

Home Insulation for Roofs has been made compulsory as of January 2013 in South Africa. It 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, Johannesburg, and Pretoria.

Types of Home Insulation

We only cover the most effective home insulation products in this article. However, a few insulation products are not worth a mention because of their inconsistency.

Some of the most important factors to consider 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.

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 to stay warmer in winter and cooler in summer.

On snowy winter days, homeowners will use a fireplace or gas heating. The reality is that the house will be more comfortable at 4 to 8 deg C. We reduce the heat flow into the home by as much as 90% with ceiling insulation. As a result, we will reduce the need for heating and cooling.

Since 2013 we must insulate all new homes with SANS-compliant insulation. For this reason, a specific R-value of home insulation is specified. We must install insulation in the Western Cape and Gauteng, 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

Regarding 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 and 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.

Drywall Insulation

We will install the insulation on the outside and internal walls. Without a doubt, the CavityBatt or Cavitylite is the most advanced home insulation product for walls. I think homes with Cavitybatt or Cavitylite are more energy-efficient than homes with brick and mortar.

CavityBatt and Cavitylite:

We fit Cavitylite or Cavitybatt insulation between drywalling panels. The benefit of installing Cavity insulation is to improve indoor temperature and stop noise between rooms.

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.
