roof insulation types

Insulation is an important energy-saving feature of any home. There are many examples of where to insulate bearing in mind that every home is different. Large homes, small homes, homes in the Cape and homes on the Highveld, North facing, South Facing, flat roofs, thatch roofs the list is endless. In this post, we cover a few roof insulation types.

Today every home must be properly insulated; new building regulations insist on insulation and that insistence should apply to all homes. From the foundation, or even the basement up to the roof installing the correct insulation is vital.

The moisture levels, air leakage and the amount of sunlight a property gets need consideration. There is nothing random about insulation and taking chances can eliminate the benefits of insulation.

Roof Insulation Types For Your Home

Where to insulate your home and how to insulate are very important. When deciding to insulate your home there are a number of factors to take into consideration.

How much energy do you want to save is the first question you need to answer. There are a number of Roof Insulation types however not all roof insulation types of insulation are equal.

The roof insulation industry in South Africa has been revolutionized with the new SANS building legislation. As all new homes built as of January 2013 must be SANS compliant installing roof insulation.

Installing roof insulation achieving the correct R value 3.70.

Roof Insulation Types in South Africa

The attic, the loft or the limited space between a flat roof and the ceiling are some of the most important places to insulate. The roof space of many homes in South Africa is the place where most energy is lost. Changing your loft from an energy-wasting loft to an energy-saving loft is not difficult. Listed are a few roof insulation types that you will benefit from.

There are two types of insulation for use in lofts and roof spaces: Batt blanket or Matt insulation and loose fill insulation.

Loose Fill Insulation

Loose fill insulation is mostly recycled news paper that has been finely shredded to a fine paper like dust. Of course, the paper will be highly flammable in the roof space and this could become a fire hazard.

A chemical compound of fire retardants rat repellants etc accounting for up to 25% are added to the paper. The down fall of this type of insulation is thither is now way of knowing exactly what thickness insulation is being installed.

With the blown method, there is no exact science when it comes to thickness or density as the product is blown in. In fact, loose fill insulation has not been a very successful roof insulation type. One reason is the fine paper dust can be moved with the wind leaving you exposed in terms of insulation.

The other problem is rain or water damage as these insulation types tend to absorb water. Until the inevitable ceiling collapse. If you have this in your roof space and need it removed because of allergies or water damage give us a call as we have a massive roof vacuum machine that removes this paper.

Loose fill insulation would not be regarded as eco friendless the product can’t be recycled and contains a substantial amount of chemicals.

Isotherm Insulation The Most Popular of The Roof Insulation Types

The Isotherm is very popular as the insulation is dust free and allergy free. This makes Isotherm one of the most popular roof insulation types.

Matt or Batt insulation such as ISOTHERM does not settle easily. ISOTHERM is a 100% green insulation product that is easy to and quick to install in the roof or attic space. Roof Insulation products like Isotherm are the most eco-friendly insulation products on the market.

The 145mm Isotherm insulation is SANS compliant and is the best insulation for your roof. When making the decision on the thickness of Roof Insulation to install always read the Isotherm technical specifications.

Think Pink Aerolite a Fibreglass Roof Insulation Types

The Aerolite Roof Insulation comes in a number of different roof insulation sizes. Think Pink Aerolite is another very effective roll form insulation. In fact, Aerolite insulation is one of the oldest forms of roof insulation. The Aerolite insulation is also very effective because it is a roll form insulation so the thickness is consistent as well.  The 135mm Aerolite is the most popular insulation in the Aerolite range and is also SANS compliant.

Before installing any form of roof insulation, checking the insulated space for air leakage, cracks, gaps and other issues that could hinder the insulation process is important. Insulation is measured by an R-value, ensuring the right product with the highest R-value is used is essential. Do not neglect hidden areas such as where decking placed over rafters. This is one many

Geyser and Pipe Insulation

Insulating around water pipes and installing a geyser blanket are both necessary areas to insulate that will maximise the energy saving in your home. Hot water cylinders are energy intensive and a geyser blanket will improve its efficiency. Hot water pipes lose heat when not lagged and this again saves energy for little extra cost. Wrap your Geyser with 145mm ISOTHERM insulation for best effect. Do not use commercially bought geyser blanket as they are useless

If your home has central air-conditioning do not forget to insulate the ducts. Installing insulation reduces the dependency on air conditioning, but when air conditioning is used, insulating the ducts increases its efficiency.

Open Ceilings or Cathedral Ceilings

Cathedral ceilings are open ceilings that extend above wall height toward the apex of the roof. Often Cathedral is built to expose the rafters and create space in a room or home. These ceilings can be challenging to insulate without disturbing the aesthetics of the room. Adequate space between a home’s ceiling and the roof deck must be provided to ensure optimal insulation and ventilation.

As with all insulation, the insulated area should be fully sealed and any cracks or areas where warm air can escape addressed. Properly seal the roof space to avoid condensation or moisture build up.

Cathedral ceilings are challenging examples of where to insulate and the solution is straightforward. Foil backed is the ideal insulation material to use in this situation. Rigid foam insulation can also be used that must be covered with a fire retardant material. It is recommended that insulation is professionally installed in homes with open ceilings to ensure optimal results.

Insulating your exterior walls

Another example of where to insulate is the walls of a home. Walls may seem well insulated but the vast majority are far less energy efficient as thought. Insulating the walls of a house is an area the home that many South Africans would not consider as an example of where to insulate.

The walls are a relatively straightforward place to insulate a home or any other building. The walls are a relatively straightforward place to insulate a home or any other building.

When building or planning to build a new property wall insulation should be considered from the outset. Building insulation into a home from the construction phase is vastly more effective than insulating at a later stage.

The CAVITY BATT is the most effective insulation for cavity walls. Wall cavities can be insulated with a variety of insulation materials. Blowing insulation into the cavity is a quick and effective insulation method. Rigid board insulation cut to size makes insulation affordable and effective. Another option is to spray insulating foam into the cavity.

Insulating the walls is an example of where to insulate that is an overlooked area but an area that can bring tremendous energy and cost savings to the home.

In a new home, it is easy to install wall insulation and areas that out of reach once constructed can be insulated. A new home built with energy saving in mind makes the entire home an example of where to insulate from the ground up.

From the ground up

An example of where to insulate that many won’t even believe is the foundation of a home. Insulating the foundation is not practical for existing homes but when building a new property it is a valuable addition to any property. Insulating foundation walls and a basement, if a basement is being built, introduces considerable energy savings to the new home.

When building a home with a basement there are a number of advantages to foundation insulation. The benefits and advantages include:

  • Thermal bridging is reduced and heat loss through the foundation is minimised
  • The damp course is protected when backfilling
  • Reduced moisture intrusion

Energy Efficient Homes use Less Energy

In fact energy efficient homes even if use wood burning fire places or other forms of heating will absorb less energy. The same applies will cooling and the running of energy efficient air conditioners in summer. The need for both hot and cold energy will be reduced substantially. Many energy efficient products for heating and cooling are on the market now.

Many energy efficient products for heating and cooling are on the market now. In fact, Energy efficient stoves, as well as many other energy-efficient appliances, are being produced worldwide in an effort to save energy.
