There are various methods that home builders use throughout the country to insulate (wrap) a home; there is the Tyvek, Thermo-ply, foam board and the zip system. The first two are very thin and offer little to no protection against the elements. The foam board is better but holes are easily poked through it and the tape used on it does not really stick all that well since it is manually applied it is not always applied correctly. The Zip system is a structural wood panel with a water resistive barrier and air barrier built right into it, when used in conjunction with the flashing tape you have a zipper effect that insulates your home like a zipper.
Sitterle Homes uses the Zip System. What do you want protecting you from the element? If you are interested in purchasing a Sitterle Home in Aliana please call me 281-804-9265.
