This is what it does if you get the right house wrap for your home. A windy day can make house wrap installation a frustrating experience at best. So cut full rolls down to more manageable sizes with a circular saw. Most saws won’t cut all the way through a full roll, so cut as deep as you can, then twist the roll until the cut is complete.
Seal Existing Windows and Doors With Tape
Smaller rolls means more tape on the horizontal seams, but the labor saving is worth the extra trouble and expense. Years ago, only vertical seams in house wrap required tape, but no longer. Now every seam must be taped, and most manufacturers recommend that a minimum of 1 in. Of the tape be sealed to each side of the seam—that’s hard to accomplish using 2-in. House wrap isn't fun to install, but with the goal of energy efficiency, it's here to stay. There have been several changes in the building codes that apply to house wrap installation (none of which make it any easier to put up), and building inspectors have been rigorously enforcing these new codes.
Comparing 5 Common House Wrap Options
Check out this complete guide on the differences between HRVs and ERVs to help determine which is best for your home. In this Rise article, we also recommend some of the best ERVs and HRVs currently on the market for passive house design. Today, most builders prefer the more lightweight synthetic house wrap options. This type of house wrap is easier to apply and broader than traditional asphalt paper. Excess amounts of water and moisture can cause mold to grow on your plywood or drywall or even weaken the structural stability of your house frame. If water gets into your inner-wall insulation, it can cause compaction, thus lowering the R-value of your home and driving up your energy bills.
What’s the Building Code for Housewrap Installation?
Bargain house wraps often have low perm rates and they should be avoided. In cold climates, this is especially true for older homes with little or no moisture barriers. Moisture will escape through the wall cavity and sheathing, and if the house wrap doesn’t allow it to pass through fast enough, it will condense and accumulate in the form of frost and ice.

My only concern in what you write is not knowing exactly what you mean when you say the seams are 'thin'. As for your pine siding, are the boards going to be horizonal or vertical? Building properly for specific climates is important for home durability. According to Joseph Lstiburek, with the Building Science Corporation, the ideal WRB perm, for balancing the inward and outward flow of moisture in a wall system, is between 10 and 20 perms.
Each material should have a specs page where they list their permeability if you want to know for sure which is more permeable to moisture. And most important is to install the siding properly, see the link in the comment above. That gap in a rain screen doesn't need to be significant, just enough for water to drain and air to rise. Some are vapour permeable and will allow walls to dry, some will not. They both have suitable applications but shouldn't be randomly interchanged. Randomly peppering your housewrap or home wrap with staples creates a lot of little holes where air can enter and escape.

Choosing the right weather barrier on a house really depends on what you are hoping the membrane will do. There are places within a building assembly where a waterproof membrane is suitable, and places where it isn't. If you tell us what your wall assembly is going to be we can help you figure out the right type of membrane. So you need to look at the wall as a whole, and don't assume that the perm rating of the weather barrier you choose will define the permeability of the exterior of your wall as a whole. An alternative to the commonly used non-adhesive housewraps are the 'peel-and-stick' membranes, and if you'd like a fancier word for them, go with this - self-adhering air and water-resistive barriers. Tyvek® HomeWrap®, a product of DuPont™, is made from non-perforated, non-woven, high-density polyethylene fibers that are fused to create a uniform web.

These options were heavier and harder to apply to the building exterior before they installed the external cladding. The asphalt-treated paper also risked lowering your indoor air quality. It could increase the volatile organic compounds (VOCs) in your home, especially if the building envelope were not air-tight.
Water vapor can easily pass through Tyvek barriers, but water in liquid form can’t. It’s as a result of these properties that Tyvek is employed in different applications. Tyvek allows the building to breathe without letting water through it. And while that solution would work fine, it sounds like an expensive one. You could save quite a bit of money if you were to just use standard 6 mil polyethene. If you pre-seal the joints in the poly with acoustic seal and even cover the staple holes, I think you could achieve a comparable air barrier but at a fraction of the price.
And I wouldn't hesitate to do these repairs for fear of trapping air, your house will continue to rot if you don't. Our preference is the peel and stick membranes as they do a much better job at air sealing a house. As for choosing one, check the perm ratings on company spec sheets online and you can see how they stack up against each other for permeability, then it's down to price and what you have access to. Depending on the substrate you're sticking the membrane to, manufacturers may recommend they be installed by first applying a primer to the surface for better and longer lasting adhesion.
As we have seen, Tyvek barriers involve reputable brands created from flash spun high-density polyethylene fibers, a synthetic material. If you have any construction work, you should use Tyvek barriers to protect your building. Tyvek barriers are designed from tough materials that are difficult to tear.
House wrap can play a significant role in protecting your home from unwanted water infiltration. This infiltration leads to many problems, including mold growth and even rotting of your interior wall system. When correctly installed, it can also help reduce air leaks and improve your home's energy efficiency and thermal performance. On the downside, house wrap and other essential air sealing techniques can cause reductions in indoor air quality if proper ventilation is not installed.
To avoid this problem, many installers will use two layers of grade D building paper. When the paper wrinkles, this creates small air pockets between the layers to help improve air flow and increase drying time. DuPont™ Tyvek® HomeWrap® is the original house wrap, incorporating unique material science that helps keep air and water out, while letting water vapor escape. As a result, it can contribute to improved building durability by helping to protect homes against damaging wind and rain that can penetrate the exterior cladding. Tyvek® HomeWrap® can also reduce home energy bills by controlling air flow and water intrusion, which helps insulation work better, allowing the HVAC system to work more efficiently. It’s a house wrap engineered to keep homes cool in the summer, warm in the winter, and dry all year round.
To address this weakness, a thin polypropylene film coating is added to seal the breaches and lock the weave in place. A durable house wrap can stand up to the handling and installing process without becoming damaged, which will lessen its water-resistance performance. Durability parameters include ultraviolet (UV) rating, tensile strength, and cold and surfactant resistance. What some people don’t understand, however, is that house wraps aren’t generally made to protect you from the air or sounds.
If you install them within 24 hours of the Tyvek layer, it may reduce the number of fasteners required for initial attachment. As per the 2006 International Residential Code and International Building Code, there must be a water-resistive barrier behind every exterior veneer. Further, the 2016 International Residential Code expanded the verbiage requiring the same thing and insists that the barrier should be developed and designed to restrict water accumulation within the wall.
When it comes to the grade foundation, the slab should extend to the bottom of the sill plate. As per the 2006 International Building Code, there must be at least two layers of WRB behind the stone veneers (synthetic, manufactured, and natural) over frame construction. Tyvek WRB performance depends on the ability of the facade to drain. I’ll explore everything you need to know about Tyvek barriers as we move along. WRB plastic materials are often lumped under the Tyvek name, much like tissue is called Kleenex. 1 U.S. perm is actually 57 Ng, that 3 billionths of a gram difference between 57 and 60 is what you call 'close enough for jazz'.
