You will find house wrap installation instructions in this pdf document: Typar HouseWrap Installation Instructions (pdf)
All types. From stucco and brick to vinyl and cedar lap siding, Typar is the ideal weather-resistant barrier.
Another term for house wrap is Air Infiltration Barrier (AIB). Preventing air leakage and weather damage are the two main functions of all house wraps. Preventing air leakage is the key to energy efficiency. All house wraps must meet industry standards requiring a high degree of air infiltration resistance, and Typar exceeds these standards on both wall section and whole-house testing. In addition, tears and nail holes can greatly affect air infiltration; unlike some other house wraps, Typar is exceptionally resistant to tearing and puncturing, which provides extra assurance of an air-tight structure.
Experts agree that a housewrap should pass water vapor 5 to 10 times faster than the internal vapor barrier. Since most vapor barriers measure at 2 to 4 g/m2/24 hr., a minimum value of 10 to 40 g/m2/24 hr. is sufficient. This is the range for various types of 15 pound felts that have been in use for years. Typar HouseWrap is 3 to 4 times greater than this minimum value range.
When attaching Typar on wood-based sheathings, such as 7/16 OSB or 15/32 plywood, apply plastic-capped staples or plastic-capped nails every 32 inches (vertically and horizontally). When attaching Typar on an open stud or non-structure sheathing, apply plastic-capped staples or plastic-capped nails long enough to penetrate the stud every 32 inches (vertically and horizontally). When installing Typar over a steel frame, use screws with washers.
Foam board has been used as a replacement for OSB and plywood Typar Housewrap in general, and Typar, in particular, should be installed over the board as a final layer prior to the installation of cladding. Typar HouseWrap will perform as the secondary water barrier.
Typar HouseWrap has a special UV coating on the light side that protects it from sun rays. If it is possible to replace it with the correct (the light) side out you will be assured that the product performance is at its maximum. Also, incorrect installation may void your warranty.
Typar does not use ICBO numbers anymore. The ICC has combined all the old numbers under one new system. The new ICC number for HouseWrap is ICC ESR-1404. You should eliminate your old ICBO numbers and begin using the new ICC numbers.
Definitely. The Typar Weather Protection System is an excellent way to protect the integrity of older homes and preserve your renovation investment for years to come. Superior air and water holdout, exceptional moisture vapor transmission, and ultraviolet stability are just a few of the benefits of Typar. In addition, you'll realize greater energy efficiency.
No. Typar cannot be used as an interior vapor barrier as it is designed to allow moisture to pass through it in the form of gasses. In general, vapor barriers are only allowed to have very low or no breathing capability.
Drainage planes are water repellent materials like building paper, house wrap and sheet membranes that are used behind cladding to defend against rain and prevent mold.
Typar HouseWrap is fire rated with a smoke spread index of 0 and a flame spread index of 30.
TYPAR Drainable Wrap can shed more bulk water at a significantly faster rate than traditional house wraps. It includes an additional integrated drainage plane of integrated polypropylene fibers for added efficiency in shedding excess water.
If you are planning to re-side your home, you should consider the Typar Weather Protection System. At the heart of the system is Typar HouseWrap which acts as an air and moisture barrier, while simultaneously allowing moisture vapor to escape from the wall cavity to the outside. Installed before the exterior siding, Typar HouseWrap protects your home from nature's harshest elements and has exceptional tear strength and ultraviolet stability. It also provides energy efficiency for years to come, which is important for energy- and budget-conscious consumers. According to DOE and ENERGY STAR®, continuous air barriers such as Typar HouseWrap could reduce your energy cost by as much as 15-20%.
Typar does not have an R-value in and of itself. It does, however, contribute to the total number of the R-value of the insulation used.
The key here is being able to resist blowing rain, snow, and sleet in the field, not just water in the laboratory environment. Tests have shown that Typar has excellent water holdout for a vertical surface.
