ceiling insulation types that improves indoor temperature


With so much discussion around insulation and ceiling insulation types, one must ask, “does insulation work?” Insulation is not just something to keep snow and frost-covered homes in the Northern hemisphere warm. Keeping sunny, warm homes in the southern hemisphere cool is equally practical for installing Insulation. The answer to the question “does insulation work” is yes.

Every homeowner is on a quest to reduce energy and save money. Not a South African phenomenon, and Insulation play a big part in saving fuel and money. Insulation keeps room temperatures constant, more comfortable levels 365 days a year. Keeping the rooms cooler or warmer depending on the time of year reduces the need to use appliances to control the temperature. In doing this, energy and cost savings both arise. The only way to save energy in chasing these goals is with the correct roof insulation.

Ceiling Insulation Types

There are many ceiling insulation types available in South Africa. Some ceiling insulation types are more effective than others. We can install insulation products on ceilings or roofs, and others are not safe to fit in the ceiling. Do your homework when deciding on the ceiling insulation type you would like to use. Ensure that you check the ceiling insulation specifications and that the R-value is sufficient per the SANS legislation.


Batt Blanket or Matt insulation is one of the most well-known and easily recognisable forms of ceiling insulation. Regarding this form of Insulation, the name to trust is ISOTHERM. ISOTHERM is 100% Eco-friendly, not just because it reduces your energy consumption. The ISOTHERM insulation product is one of only a handful made from recycled plastic cooldrink bottles. We can recycle PET bottles to produce subtle and soft polyester.

When fitted into the loft, it will offer outstanding insulation properties. Many other similar products are made from natural and human-made fibres that come in rolls that we can trim to the correct size. The Isotherm Insulation is SANS-compliant and will achieve the proper R-value for South Africa. Please read all the Isotherm Specifications to make the right choice. The 145mm Isotherm insulation is SANS-compliant for the Western Cape region.

Ecose Insulation

Ecose Insulation is imported from Germany and is regarded as one of the highest-grade Types of Insulation. The Knauf Ecose is Eco-friendly Insulation manufactured from Mineral Wool and glass wool. Ecose Insulation is the only Insulation that is formaldehyde-free. As a result, the Insulation is fully recyclable. Find out more about Ecose Insulation and all the benefits related to the product.

Loose Fill Ceiling Insulation

Another ceiling insulation type is loose-fill Insulation—this Insulation is made from recycled paper, Foam, or polystyrene pellets. Blown into the loft space or ceiling, filling gaps in and around protruding objects, loose-fill installs quickly. The downside to this material is that it settles fast, unlike Aerolite insulation, which does not compress.

Once settled, its insulation properties drop, and the product may need replacing sooner. Another downfall of loose-fill ceiling insulation is the wind factor. The wind blows the Insulation in the roof, causing problems with the effectiveness. Loose-fill ceiling insulation types are not very popular in South Africa because of the ceiling damage if you have a roof leak, as these products tend to absorb water.

Rigid Board Polystyrene Ceiling Insulation

A favourite and relatively affordable ceiling insulation type is rigid board insulation. It is made from high-density XPS Ceiling Boards. It is produced from various materials such as polystyrene, polyurethane and other forms of rigid Foam, and it is made to measure large boards.

The rigid board has excellent insulation properties and is useful for small insulation jobs. The panels are lightweight and can be cut to size for use anywhere in the home, not just the ceiling. Rigid board insulation types are not used in the ceiling space as they can be a fire risk.

But just what is Insulation?

There are many ceiling insulation types and other products for use in other areas. In simple terms, Insulation minimises heat loss or heat gain in a room or building. Like a thermos flask keeps coffee hot or juice cold, the Insulation does the same in your home. It is essential to install Thermal Insulation products with high R- values. The Aerolite Thermal Insulation not only has the highest R-value; it also has the A/1 fire rating. The best Thermal Insulation products are SABS approved and should also have a class A/1 fire rating.

Most people are aware of ceiling insulation types for roof spaces. However, Insulation is also available for gaps in hollow walls, hot water systems, windows, and doors. Ceiling Insulation is available in many formats, each with different uses due to its other properties. Bulk Insulation is one of the most common ceiling insulation types.

Insulation has many applications from the industrial side of boilers and pipes. Nowadays, Home Insulation has become a significant factor in energy-saving conservation.

Reasons To Install Ceiling Insulation

Every South African need to take responsibility for saving energy. Load shedding in recent years has changed how people look at electricity as they have woken up to the need for useless. One cannot rely on the government or Eskom alone to solve South Africa’s energy problems. We all need to play our part in saving energy.

Insulation plays a big part in helping the nation reduce electricity demand. Installing one of the many ceiling and other insulation products makes financial and environmental sense. Electricity is set to increase in price further in the coming months. Installing Insulation will offset some of this cost for well-informed households. By reducing energy demand, colder or warmer homes require less energy to keep comfortable, and utility bills drop. Less energy used means less reliance on electricity, and everyone, homeowners, government, and ESKOM, are all happy.

Many would agree that a comfortable home or office space is one of the best reasons to install Insulation over and above the cost and energy savings. Ceiling Insulation does make a difference in ambient temperature. Offices become more productive, and houses become happier as life becomes less stressful.

There are countless reasons to install Insulation; doing so is not expensive in the long run. Double Glazing can increase the value of a property. Ceiling Insulation also absorbs sound, in some cases, improves security.

At what point can Insulation be installed?

In 2013 building regulations required we must insulate all new homes. There is no wrong time to install Insulation, but installing new ones ensures the best results. When constructing, new home insulation designed to work better and meet or exceed the prescribed specification is more comfortable.

We can install Insulation anytime; the best times are today and yesterday. Despite the relatively temperate climate in South Africa, all homes can and will benefit from good or more appropriate Insulation. Their R-Value measures insulation products. The R-Value is a simple way of measuring how good a product controls heat flow through it. The higher the R-Value, the better the insulation properties a product has.

The current building regulations around Insulation determine the R-value of Insulation installed by the climatic region. As a result, the laws are designed to maximise energy efficiency. Having cooler homes in summer and warmer in winter reduces electricity use substantially. Most homes built before 2013 have no or insufficient insulation. It is not complicated or overly expensive to install Insulation to meet better building regulations. Once you fit any ceiling insulation type, the benefits will show almost immediately.

How do I get Insulation installed?

For ideal results, professionals should install Insulation. Any DIY enthusiast can easily install some Ceiling Insulation types with excellent results. Just saying, “I want my ceiling insulated”, is not always enough. Having a professional insulation installer give you advice is a more appropriate insulation solution.

A professional insulation provider will provide the right solution and ensure products are SABS-approved and quality is of a high level.

It makes absolute sense to consider the various ceiling insulation types. Then install the most appropriate for your home and budget. Insulation will save you energy and will save you money. There is no denying it.

So Many Ceiling Insulation Types What Is Best?

The best ceiling insulation must have great Thermal Insulation properties. The Insulation must also be SABS-approved and SANS-compliant with an excellent fire rating. It is a difficult question as all homeowners have their own opinions on this subject. However, my opinion, after 30 years in the industry, I am steadfast in the best ceiling insulation type. Over the last 30 years, we have installed all kinds of Roof Insulation, followed by Knauf Ecose Insulation Products. Roof Insulation Cape Town will only install insulation products that we believe.

Our choice products are Aerolite Insulation and Simply Green Insulation. We do not install cellulose, and this is a product we will never fit. We are not interested in insulation products that have high chemical content. And the fact that cellulose is a fine, paper dust type insulation means it will be affected by strong winds. When our teams remove cellulose, we often find the Insulation has blown to one end of the home with very little coverage on the other side.

We stock all roll types of Insulation. Isotherm and Aerolite Ceiling Insulation Types are popular and account for a 25% referral rate. However, we only install the Isotherm and aerolite insulation. These products are tried and tested and give the best results.
