Can Housewrap 'melt' under steel siding?

I am installing metal siding on a new construction Home and planned on installing Hydrogap by Benjamin Obdyke underneath. The siding contractor has expressed concern that the paper or the dimples on it may melt.
Has anyone ever experienced housewrap 'melting' from the suns heat.

Slab on grade house and garage : can I pour the floors once the shell is up?

I currently have the footings frost walls (4'), and the sandy base filled in and tamped for the slab. The house is roughly 50'X30', 2 storey, and the floor joists can technically span 30' (24" deep trusses), but the plan has a "supporting" wall roughly in the middle of the width to keep the floor span at 15-17'.

The garage is 30'X40', with no supporting walls (wide open).

Building on a rock ledge

Building a foundation is usually a pretty straight forward process in my part of the country. But I am considering a small lot that is likely more rock ledge or boulder than soil. The lot has great views in several directions, but I suspect the rock has deterred at least two previous owners from moving forward with their construction plans.

Roof assembly

I’m insulating the roof of my log cabin in northern MN, zone 7. Trying to get to r49 topped with standing seam metal. Question is what underlayment do I put on the first layer of decking under the insulation and what do I put on the sheathing on top just under the metal? Also, vent the metal or not? Thank you, Andy

Cellulose

I thank everyone for their answers. It seems that I jumped the gun a little. I didn't even consider the weight of the cellulose and have already hung the ceiling drywall. Is there anything I could do after the fact to support this weight. Maybe strapping on top of the joist to help carry the load? Any other suggestions would be welcome.
Thank you

Neat glass and other self-cleaning coatings: blessing or curse?

Looking at new windows and Neat Glass from Cardinal is an option. Titanium dioxide coating with "self-cleaning" properties. Looks like there is a 10 year warranty, but I'd like to hear opinions, mostly for long term ownership. I'm afraid it could turn into a streaky mess once the coating begins to degrade unevenly.

Cellulose

I am in the process of building a new home and plan on using cellulose insulation in the attic. I hope to insulate the attic to r-60 which I believe is about 17" thick. My home has energy heel trusses (2x6 bottom chord) spaced on 24" centers. I have 1/2 drywall glued and screwed every 12" to the underside. Im worried about the weight of the cellulose on the drywall especially after it absorbs moisture from the air. Should I be concerned and if so what precautions should I take? Thank you.

Are there more cost effective ways to dry an old basement?

I have a 100 year old 21" thick fieldstone foundation in region 5 that has cracks and leaks water into the basement in the rainy season. I have read the above manual mentioned above,

https://www1.eere.energy.gov/buildings/publications/pdfs/building_americ...

as well as a fine home building article by Joseph Lstiburek as well and is there a way to use any less expensive product to allow for an interior drain plane such as dimple mat backed up with taped XPS or EPS foam instead of just closed cell spf? The cost of 3" spf is around $5 and will price me out of being able to do my home.
