Insulation FAQ's

Q: What is an R rating?
A: It is a score given as the result of testing that measures how a product resists heat transfer.

Q: What product do I use to insulate?
A: This depends on application, stage of build , type of walls, roof etc. Please ask us for advice.

Q: What does Sisalation wall wrap do?
A: This is a vapour barrier to protect internal linings, it has a very minimal R value .

Q: How many Turbo Beam roof vents will I need?
A: We recommend one per 90m² of roof area, it is also important to install eave vents to assist the ventilation process.

Q: Is Earthwool flammable?
A: No, all Earthwool insulation made by Knauf is categorised a non-combustible.

Q: Does Earthwool contain formaldehyde?
A: No, Earthwool is one of the few glasswool products that use an organic binder called ‘Ecose’ rather than traditional binders containing formaldehyde.

Q: Why are there different R values for batts with the same thickness?
A:
Some batts are made with a higher density. This is generally done for acoustic purposes.

Q: How much will insulation actually cool my house?
A:
Given the variables that are inherent in house designs, it is impossible to provide precise information regarding what will happen to indoor room temperatures. However, we do know that roof space temperatures can rise as high as 70˚C, and a combination of roof vents and insulation can easily reduce this by 30 - 35˚C.
