What does R-value mean?

The R-Value refers to the thermal resistance of the insulation. It expresses the ability of a particular thickness or material to resist heat flow. Different R-Values can be achieved with a range of products and applications.



What is the fire rating of Envirowall?

Depending on the product used, the fire resistance varies between 230 degrees and 1000 degrees

How do you install Envirowall in brick?

We drill small 20 cent of size holes in the mortar between the bricks, then using a specialised hose we fill the cavity. On completion we patch up the holes.

How do you install Envirowall in weatherboard?

We drill small 20 cent of size holes in the weatherboards, then using a specialised hose we fill the cavity. On completion we patch up the holes.

Can Envirowall be installed in internal walls?

Yes. Envirowall can be installed internally acting as an acoustic barrier between rooms.

What material is Envirowall?

We have the option to use two types of material with install with the envirowall method. We install a fibreglass or a stonewall product – both of which have their positive attributes.

Why is Earthwool “not as itchy”?

The ‘super soft’ feel of Earthwool comes from a revolutionary, patented binder made using renewable bio-based materials.

Why choose polyester?

Polyester is a good option for people with allergies as it is the same material found in doonas and pillows. Polyester will not corrode or deteriorate over time.

What is the difference between foil and batts?

Foil acts as a reflective form of insulation reflecting the radiant heat away.

Bulk insulation (batts) slows the transfer of heat down.

What is SuperQuilt made out of?

SuperQuilt is a multi-layer foil insulation which deals with all forms of energy transfer, conduction, convection and radiation.

It is only 40mm thick but has 19 layers of material including reflective foil, Expanded-Polyethylene & Polyester Wadding.

Why use SuperQuilt?

SuperQuilt works most effectively by reflecting infra-red radiation. It is a solution that is thin and flexible. R-Value able to be reached is between 2.5 – 4.9.

What is cellulose?

Cellulose fibre insulation is produced from 100% recycled paper and covered with a silicon coating.

Why use cellulose?

Cellulose is installed without gaps and covers your ceiling joists to increase thermal efficiency, comfort and save you money. Internationally proven to have the lowest global and local environmental impacts during manufacture and is very cost effective. Cellulose is sustainable.

What are the benefits of Celbar Feelrite?

Cellulose fibres , organic in nature, treated with adhesive and fire resistant chemicals. Provide excellent sound and thermal barriers. Celbar is a bulk insulation option that provides complete coverage.

Why do I need to wrap my house?

Decrease air flow and acts as a secondary barrier to insulation allowing greater efficiency. Wraps shield your home from radiant heat. They also assist in protecting structure during build from the weather – providing vapour barrier or vapour permeable layers.

How does Envirowall stop condensation?

Envirowall is vapour permeable allow the construction to breathe

Can we install Envirowall from the inside?

In special cases of render or other limitations Envirowall can be installed from the inside

How big are the holes made during Envirowall install?

About the size of a 20 cent piece

Can Envirowall be installed into existing houses?

Yes. Envirowall – Cavity Wall Insulation is a perfect product for existing brick, brick veneer and weatherboard homes. The install is non-intrusive as it takes place from the outside of the home.

Thermal insulation, how does it work?

Having efficient air-con and heating is great but to really receive prolonged benefits, a household needs to minimise the gaps. Thermal insulation works by filling the gaps in your house so you control the airflow, reducing the warm air escaping in the Winter and the cool air in the Summer. With time and weather conditions the materials used to build houses shrink and expand creating gaps, the insulation marks a constant barrier from air transfer.

What types of insulation can be fitted to exsisting homes?

There are retrofit insulation options available for your home. We have products available for ceiling, walls and suspended floors.

Can acoustic insulation be retrofitted?

Absolutely. We have options for homes and commercial projects inclusive but not limited to carparks, cinemas, music halls, meeting rooms just to name a couple.

Can insulation help reduce unwanted sound?

Yes. Specific types of insulation act as a barrier to absorb sound. The products for best performance in the household include a selection of batts, cellulose and Rockwool.

What is Cellulose Fibre

Cellulose fibre insulation is produced from 100% recycled paper meets the stringent requirements set by the Australian Greenhouse Office and ratified by the Kyoto Protocol for Five Star Energy rating systems for roof insulation…

When it comes to roof insulation the choice should be cost effective, environmentally sound and sustainable and energy smart helping to reduce greenhouse gas emissions. 100% Recycled Natural Cellulose Fibre is leading the world in smart eco friendly insulation solutions.

What insulation can be fitted to existing homes?

External Cavity Blown In Granulated Rockwool Insulation
Cellulose in internal walls

Cellulose Blown In

Underfloor (if space permits):

How do I know if I have any wall insulation?

There are a few ways to check if you have any wall insulation.
1. Infrared
2. Pulling off the powerpoints and checking behind them
3. Looking down wall cavity from roof
4. Knocking on wall – can sometimes be inaccurate if loose plasterboard or inadequate fill

What is the difference between aa FF130 Tenmat FLANGED Loft Cone and a FF130 Downlight Protection Loft Cone?

FF130 is the one designed for Australian conditions, the cone is for USA with their lower voltage. The flange refers to a flatter side that enables fitting closer to the beams. It is fire resistant material and has a narrow side specifically for areas where the LED/downlight is close to the beam.

I have halogens in the bathroom fitted with 35w globe, should they have a Tenmat cone or cover over them or does that cause them to overheat?

The Tenmat was originally designed for halogens to restrict the matter of overheating so it’s a good idea to install them.

The downlight install seems time consuming – cut hole, pull wire through of the separate driver to outside and top of cover, silicone that up and silicone the cover to the ceiling?

Yes, that is the complete process so the transformer can sit on top of the cover. With the LED lights the cover can just sit over them.

My instincts are to ask the electrician to install the cones or covers when installing the LED downlights before the insulation is installed. Do you agree?

Yes, this is the best method of install while the contractor is there. Electricians are the best people to install.

What is the fire resistance of the downlight covers?

Fire rating tested to comply with IEC 60598

How long does the Envirowall install take?

Depends on the size of the job but generally a whole house takes 1-2 days

What is Expol?

Expol is an underfloor insulation made out of rigid polystyrene with flame retardant additives. It will not sag over time and holds a 50 year warranty.
