Hello we are planing on building a Cottage in Ontario, Canada.

Plan is for a full ICF home. Basement to roof.

I'm thinking Micro-rebar by Helix, they look like DNA or a spiral nail.
It is the only approved Non-full rebar available. Benefits I guess you only have to put in vertical rebar and bottom and top horizontal,

You add several pounds per yard of concrete at the truck depot. It makes the ICF like a chocolate chip cookie vs layer cake idea.

It is suppose to be 300% stronger. Saving time and cost on rebar.

Also thinking of Form-a-drain for the footings. it builds your drainage and radon all in one plus you don't have wood to deal with.


also planning SIPs on roof vs truss and spray foam.


HVAC ideas?

We will have a big wood stove with endless supply of fire wood.

HVAC I have multiple ideas.

Top contenders. Mutsuibshi heat pumps ( CON-I don't like the suitcase look in the house, PRO- cheaper and efficient. ) supplement with with big wood stove

Geo-thermal- Con- Expensive Pro -Self sufficient
Radiant Floor heat pump boiler. PRO- Warm feet radiant floor heating ( I that, ) Con's Propane delivery.

Wood pellet boiler. Cons- Expensive $10,000-$16,000) and storage of wood pellets. Quality of Pellets.

Solar would be great to get off grid buy Tesla Solar is not available here yet.

Thanks in advance

any other advice would be great! :)

The Helix is soft steel with a galvanized coat. I know with full size rebar there is a problem with anti-rust coats in that they tend to get micro-damage during handling and installation. If moisture gets in, then they start rusting at those points and it spreads. Since you are using this as a serious part of your structure I would suggest you look into additives that will make the wall impervious to water, not coatings you paint of the surface, but ingredients that are part of the entire wall. Protect your investment.
