I was told to use zip ties to attach the pex to the wire mesh for in slab radiant. Is there something special about these zip ties, or can I just use regular zip ties that I can get for free? http://www.supplyhouse.com/Viega-15304-Zip-Ties-Bag-of-100-5305000-p

Putting an addition on. I'm setup for (2) 10ft doors. Trying to decide on what material to go with though. Is vinyl the best option in terms of maintenance? What about in terms of insulation? Having a hard time choosing the right door.

I know there's a ton of posts here about radiant flooring, I just haven't been able to find the answers to a few questions I am wondering about. I am doing a 2 car garage with living space above. It's 26x32, attached to my existing home. I want to do radiant heat in the floors for both levels...
