Hebel Vs. Bricks for new house in Sydney

It can crack when Hebel joints under the render expand or contract as there is no mortar used to connect Hebel panels together.

Hebel Vs. Bricks for new house in Sydney

Hebel requires acrylic render, so add up $60-$75 per sq m + GST to your calcs. When not rendered properly, cracks are probable.
Bricklayers are expensive in Sydney, some of them…

To have gas or electricity ducted heating !!

Moreover, you can also have ducted mini-splits, if you really want.
You also save a fortune on the installation costs and can use attic for storage.

Vinyl Plank Flooring Questions Answered

Interesting article. They have measured 0.15-0.7 mg/100g which is beyond the most stringent standards (E0 is <3 mg/100g, Japanese standard is <1.2mg/100 g).
Most people can't smell formaldehyde at concentrations of…

Also, keep in mind, only few green certifications are testing for phthalates when measuring off-gases, most of them don't.

Agree to that, do your own research.
Formaldehyde is possible only in engineered wood (and laminates), not in hardwood, BTW (wood does not contain formaldehyde naturally but it is rather used…

If your vinyl planks carry phthalates (as most of them do), you are not okay, because they off-gas.
And yes, there is a difference between outdoor/indoor exposure as well as between…
