Situation is 3 bedroom home, recently built on concrete piers. Piers are
square 12"X12" variety. Closest part of wooden sill to the ground is 18" in
the rear of the house to over 3 feet in front of the house. Subfloor is
insulated with fiberglas type insulation, and has fine nylon net throughout
bottom. House has cement board siding similar to James Hardie's horizontal
siding. Homebuilder did not install a skirt. I desire to the house to have
a skirt around the bottom where the piers are exposed of course.
Have landscaped the soil to cause water runoff from roof and surrounding
area to move away from the house. The natural slope of the land is from the
back to the front of the house for watershed during rain periods. Typical
rain is heavy at times, with longer dry periods. No water accumulation is
anticipated around the house due to the grade of the land.
Yesterday was sunny, windy and warm (low in a.m was 62F, 85F for high). The
house stayed less than 70F until around 5 p.m. when direct sunshine was
below roofline. House slightly warmed until sunset. So, am satisfied with
insulating properties of the house. The house faces south.
There are just few varmints to be concerned about in the area, other than
the occasional domestic dog or cat. Namely armadillos, roadrunners,
raccoons, possums, occasional white-tail deer, black vultures, and other
birds. Except for the domestic-type animals, the remainder would be
transients if they sought refuge under my house as they shy away from
people. And wouldn't expect any to pry any type skirting to make entry.
Have rough idea how to apply the skirting, namely, use PT lumber for frame
to the piers and bottom side of the sill (subfloor frame sits on sill), then
apply the skirting material. But, this isn't specific enough. Any weblinks
on exactly how to do this?
Brick, or cement, or any other material that practically seals, except for
installed vents, the crawlspace, I am not consdering. Am considering
plastic lattice, James Hardie's perforated soffit (water contact?), or any
other ventilation conducive material. Don't want to spend alot of money.
But, am interested in maximum ventilation, varmint entry restrictions. Any
BTW The sill perimeter is vertically parallel with the outside framed walls
and subfloor framing perimeter. The sill perimeter is also vertically
parallel with the concrete piers on outside of the house. The perimeter
sills are doubled up 2X12 PT lumber. The walls are clad with OSB plywood,
with cement, horizontal siding over that. The cement siding drapes 2" below
the bottom of the sill perimeter bottom. Making this more interesting, and
less straightforward. Maximum pier to pier OC is 8', to as little as 7' 3'.
