Yes, house wrap absolutely helps with drafts. It serves as a vital exterior air barrier that seals the seams and gaps in your home's sheathing, preventing outside wind from blowing into your wall cavities and cooling off your main insulation.
Behind quality siding should be a continuous house wrap—a vapor-permeable, water-resistant layer such as Tyvek® or HardieWrap®. Think of it as a windbreaker for your home. It stops air and moisture while allowing walls to breathe.
There are several problems with Tyvek® House Wrap that diminish its ability to resist water and air.
It makes financial sense to start your home energy upgrade with insulation. Otherwise you're paying to heat your home, only to lose it through attics, walls, windows and doors. Insulating your home helps to: Reduce your heating bills by improving your energy efficiency.
Tyvek® can reduce air and water infiltration to help prevent drafts and water damage. But it is also vapor permeable, to allow water vapor to escape when it does get into walls.
Yes, mice can easily get in under siding. Because their skeletal structure is incredibly flexible, they only need a gap about the size of a dime (or roughly 14one-fourth14 inch) to squeeze through. The hollow spaces behind siding act as highways, allowing them to climb and access your attic or walls.
On the sides and above the door, use foam tape. Underneath the door, you may need to install a door sweep to seal any gaps. A door sweep is usually a metal strip attached to the bottom of the door with a rubber or bristled strip below that.
As a general rule, house wrap should be installed before the windows. This ensures a "shingled" effect, allowing water running down the wall to flow over the window flashing rather than getting trapped behind the wrap.
Mice are curious and always searching for safe, snug, and warm nesting sites. Attics filled with blown-in insulation provide an excellent option–from the mice's point of view. As long as there is a ready food source. Mice are omnivorous and will eat and chew on almost anything including wood and electrical wires.
While Tyvek manages moisture, it's not immune to all moisture-related problems. Two of its main issues are mold growth and sensitivity to surfactants.
"Better" than Tyvek depends on your project. For home building, Zip System Sheathing and Henry Blueskin outperform traditional house wraps by acting as fully adhered, all-in-one moisture and air barriers. For camping, Polycryo is significantly lighter, more puncture-resistant, and packs smaller than Tyvek.
Because spray foam can trap moisture, hide the condition of the roof, make it difficult for surveyors to inspect, which means risks like timber decay, dry rot, and not forgetting increased fire risk. If you've got it or you're buying a property that does, this is something you need to know upfront.

The ZIP System and Tyvek both act as weather-resistive barriers (WRBs), but they work very differently. ZIP replaces standard sheathing and housewrap with an all-in-one coated board and taped seams. Tyvek is a breathable housewrap layered over standard oriented strand board (OSB) or plywood.
Yes, you can staple house wrap, but with a major catch. Most manufacturers (like Tyvek) require plastic cap staples or cap nails rather than standard bare staples. Standard staples are too small and can easily tear through the wrap in windy conditions, leaving your sheathing exposed to moisture.
It is possible for moisture and air leaks to enter through these fine lines and seams, wreaking havoc behind the siding that you may not even notice until significant damage has already occurred. Despite the good qualities of vinyl, it does pay to have extra insurance in the form of house wrap.
House wrap alternatives fall into three main categories: integrated sheathing, fluid-applied barriers, and traditional asphalt paper. These options replace standard spun-bonded wraps (like Tyvek) to provide superior structural integrity, easier tape bonding, or historical moisture management.
What time of year is Insulation cheapest?
Yes, insulation is tax-deductible in the form of a federal tax credit, specifically the Energy Efficient Home Improvement Credit (Section 25C). You can claim 30% of the cost of insulation and air sealing materials, up to a maximum annual credit of $𝟏,𝟐𝟎𝟎.
Effective wall coverings for cold walls include thermal insulation wallpaper (PE foam or cork), insulated lining paper, rigid foam boards, and thick acoustic panels to reduce heat loss and improve warmth. Popular solutions include Adhesive Thermal Insulation Wallpaper (3.28 x 32.8 ft) and 19. 7 in. X 16. 4 ft. Thermal Insulation Wallpaper, which offer easy installation for immediate improvement.
To instantly block cold air from coming under your door, you can use a slide-on door sweep, a weighted double-sided draft stopper, adhesive weather stripping, or even DIY alternatives like a rolled-up towel or a pool noodle stuffed inside an old sock.
More recently, some homeowners — particularly in Scotland — paint their front door red in order to signify that they have paid off their mortgage. This mortgage-free announcement is of course exciting to homeowners and we think it's worth proclaiming!
Choosing between rubber and vinyl foam weather seals comes down to durability and gap size. Rubber is ideal for high-traffic exterior doors and extreme climates due to its longevity and shape retention. Vinyl foam is better for budget projects, irregular gaps, and indoor applications since it is highly compressible and less expensive.
