Health & Wellness Hut builder/contractor

Fibre reinforced cement board is used a lot in construction in Australia with steel or timber stud walls.
If available in Phils I would rather build a house with this system than the brick and render walls. Its fast, less moisture and looks good if done correctly. I have the Matix cladding on my current house but you really need to seal the joints right.

As far as strength goes its in the stud walls so just beef up the steel pillars if needed or if doing a second level do the upper floor in steel not concert.

I have used the metal stud and hardi-flex panels on the roof-deck covering the top of the stairs. Saves a lot of mess mixing sand and cement.
For insulation I used the foil insulation twin walled and on both sides of the inside of the panels.
I wouldn't built a house with this materials though.[/QUOTE]

It is odd to me that you quote my question, but do not give a sound answer why not to use it, that was the whole idea behind the question?

 

HardiFlex and other products are made from wood fiber and cement. They are designed for exterior or interior use. The generic term is "Wood Fiber Cement Board". Wood has negative connotations so the marketing people involved have dropped the term wood and the product is commonly presented to consumers as Fiber Cement Board. It can last 60 years outside.

There are the Fiber Cement Board flat panels like HardiFlex and there is Fiber Cement Siding or cladding that has a wood texture. Products come in many sizes and thicknesses and sometimes have additional reinforcement.

 

Not very strong, invaders could just kick a hole and enter, even with the best insulation heat and noise would be an issue. Coconut husk would not help.
You're welcome.

I prefer to think of most member's answers as an attempt to help - this is the solid foundation (that word keeps me on-topic) of the Forum. If people don't always exactly hit the target then that needs to be accepted and for the person to seek better advice elsewhere.

Thanks for your answer. Much appreciated.

 

LOL - Another completely baseless and unsubstantiated statement.

I assume you are comparing this to the local blocks made with "mountain sand" and then plastered.

Concrete hollow blocks have the worst thermal insulation properties of any building material. Concrete hollow blocks are also known as concrete masonry units. (CMU) A 4 inch thick wall made with concrete block has an R value less than 1 (0.8) whereas a typical 2 x 4 wall with wood studs and mineral insulation has an r value of 12.44.

Wood shavings have an R value of 2.2 per inch. So a wall with 4 inch studs would have and R value of 9 just for the wood shaving alone. (Not including the sheathing inside and out.)

Having been made with dirt, (mountain sand) local blocks are pitifully weak and have to be carried very carefully when placing them in position. The structure of local buildings is dependent on the post and beam construction (hopefully the contractor did not over-water the concrete). The walls are simply filler material. Typically the "mountain sand" blocks used for walls are not filled with reinforcement and concrete.

I have experience with wood fiber insulation in wood framed homes and it makes a great insulator for sound and heat. The thermal insulation is an order of magnitude better than concrete hollow blocks. You would have to keep it "under the roof line" so it stays dry.

 

60yrs not a bad lifespan, most houses using CHB will have major failures long before that time? there is a good reason that; most if not all are not rendered from the foundation up, so we have steel encased in a porous hollow block, OK there is some mortar of sorts around the steel but mostly from what I have seen the stee

Thank you Sir for your very interesting comments here, I do agree with most of what you say but, perhaps you are not quite correct with your R value of CHB, the correct figure should be -R10 all during the day they slowly heat up to the ambient temp of the day and even more if the sun gets to them, then they slowly give that off all that heat during the night, it is an easy problem to solve all you need is high powered AC units in most of the rooms, it is not the first time I have a group of Foreigners boasting about their Electric bills or the amount of HP they have in all their AC's, month, most were spending more than my P12k a month rent and Proud of it, but they all had a common bond? they lived in CHB constructed houses.
Now a 4x2 inch steel stud framed house well insulated in the wall gap needs little if any AC and if one is used 30mins would be all you need to cool the air inside and it would stay that way for a long time, only an Eskimo would need it all night?

 

I'm not comparing anything. You mentioned blocks not me. I said hardi flex is not strong, intruders could kick a hole in and enter. And coconut husk is not a good insulation.
DAVE 1952, asked me a question and I politely answered.
So you are saying. Hardiflex is strong and could withstand a break in from intruders. And coconut husk make a suitable sound-proof and keep the heat out.
