13 Oct Comprehensive Guide To Home Insulation
If you want to reduce your energy consumption, one of the most cost-effective ways is by installing premium ceiling insulation Batts. In fact, studies suggest that households save about 45% power by having well-insulated homes. But insulation does not only keep the expenses low, it will also make your home comfortable no matter the season.
The best ceiling insulation resists heat from flowing into your home which cools the house during summer and maintains the warmth during winter.
What Is R-Value?
The R-value is the unit of measure used in identifying the thermal resistance of a material. Materials with higher R-value have greater heat transfer resistance and are more effective to give an insulating effect. This leads to saving more energy, thus, saves you from hefty expenses as well.
Up R-Value, also referred to as winter R-value, pertains to the thermal resistance flow out of the house which is necessary to keep the heat in during winter.
Down R-Value, also called summer R-value, pertains to the heat flow resistance out of the home during the summer.
Total R-Value is the combination of Up and Down R-value.
Types Of Insulation
Before having a ceiling insulation installation, there are several types of insulating types that you should know about: bulk, reflective and blow in insulation.
Bulk Insulation
This type of insulation is the most common and is generally the most cost effective. It works by confining air into thick layers of tiny bubbles which restricts the flow of hot air in and out of a property. Produced in a variety of materials such as Fibreglass, Rockwool or cellulose fibre, bulk insulation is the top choice of many homeowners and is best when in a Batt form which is a big rectangular piece of insulation as this can be easily moved and replaced if required.
Reflective Insulation
As its name suggests, reflective insulation has the capacity to deflect heat. This function makes it suitable for hot and sunny. Reflective insulation is usually made of aluminium foil that is laminated onto plastic or paper. This type of insulation is ideal to place within the wall or right below the roof. However, this really needs to be installed at the time of construction.
Blow In Insulation
This type of insulation is most suitable for retrofitting into wall cavities or tight access ceiling spaces where access to install batts is not easily performed. External brick veneer walls with no Insulation have an approximate R value of R0.5. With Rockwool blow in insulation an R rating of between R3.0 R4.0 can be achieved.
Rockwool delivers five times the density of the average ceiling insulation batt, fully filling the cavity space, blocking gaps and absorbing flanking noise that would otherwise reverberate through the cavity. Since Rockwool does not shrink or sag, the cavity will remain tightly filled and the insulation will continue to provide thermal and acoustic benefits for the life of the building.
Rockwool is the only product approved by the CSIRO and the Building Code of Australia for installation in existing walls. Rockwool is manufactured in a water repellent form that can be easily blown into the cavity of Brick Veneer walls. It is both a thermal and acoustic product and is Tested to AS1530.1[1] by the CSIRO and Certified as BCA non-combustible.
