There is a light-weight Tyvek available at kite hobby outlets. It is called kite Tyvek and it is about 1.3 oz per sq. yd. compared to about 1.8 oz per yd. for house wrap. Also, house wrap is prone to accumulate static electricity which makes a lot of dust and other stuff on the ground cling. The kite Tyvek is less prone to "static cling" and has a softer feel. Google kite suppliers and look for the Tyvek they have in stock; you can buy it by the yard.
