[at-l] Tyvek/Housewrap info (long)
With all the interest in tyvek I did a little research and came up with some
goodies. Most of this deals with Dupont Tyvek(R), the last little section
covers Owens Corning Housewrap(tm)
First, I called some local building products suppliers. The Riemeier Lumber
Company (on the www) is a supplier of better quality building products, which
means you use 98% of a load of lumber instead of rejecting half the load.
They are also very knowledgeable in the products they carry (no teenagers
here). All products carry a premium price since you're paying for quality,
knowledge AND service. Their tyvek comes in 150' lengths and is either 9'
wide ($142.00 per roll) or 10' wide ($158.00 per roll). The tape is $9.99 for
a 50 meter roll (about 163'). They sell the woven tyvek meant to allow
water vapor to pass, but not water as a liquid.
Furrow Lumber, which goes under the name of Cashways, Payless and some other
names nationally sells only 9 x 100 sheets of tyvek for $89.99. No tape
available and they couldn't answer any of my questions about the product.
My own personal caution, I donUt know how well this stuff will stand up to
sunlight. This tyvek was meant to be used as a building wrap, underneath some
type of siding and _might_ degrade under sunlight. Tyvek used for car
covers might have some UV protection built in, again, I don't know.
Anyway, the rest of this dissertation comes edited from the Dupont and Owens
Corning web sites and Yahoo!.
Tyvek is made into a variety of products like: semi-custom car covers,
jackets and accessories, protective apparel.
