Around 60 percent of all housewrap and weather-resistant barrier material sold in the United States goes onto new homes. The rest lands mostly on houses being re-sided, where a new exterior is the best chance to upgrade the moisture protection behind it. Those two jobs place very different demands on the material, and manufacturers have responded with products tuned to each. Builders who understand the split can match the barrier to the project, and the numbers from recent industry research show how the categories are dividing up. The housewrap choice starts with knowing what the market data says.
Every exterior wall in modern construction needs a weather-resistant barrier. Building codes require a water-resistive layer behind the siding, and the material that fills that role has evolved from asphalt-impregnated felt paper to a family of engineered products. The market research presented at the Housewrap 2019 conference tracks that shift with hard numbers on installations, and those numbers show where the industry is headed.
How the Housewrap Market Splits by Project Type
The 60/40 split between new construction and re-siding shapes product development. New-home builders buy in volume, install on predictable schedules, and favor materials that go up fast with minimal labor. Re-siding jobs are smaller, more varied, and often expose older framing that needs a more forgiving barrier. Manufacturers track both streams, and the product mix on dealer shelves reflects the balance.
Project type also drives how the material gets installed. On new homes, the barrier goes on in one coordinated pass with window and door installation, and the crew controls the sequencing from the sheathing stage forward. On re-siding jobs, the crew works around occupied houses, existing trim, and irregular wall planes, which favors materials that conform to rough surfaces. The weather barrier research covers every category sold today, from the least expensive rolled paper to the most expensive fluid-applied coatings.
New Homes vs. Re-Siding Work
The market split matters for purchasing decisions. A production builder framing forty houses a year buys housewrap by the pallet and cares about price per square foot, installation speed, and warranty coverage. A remodeler replacing siding on one house at a time can justify a premium membrane because the labor to install it is a small fraction of the total job cost. Both buyers end up in the same aisle, but they walk out with different products.
Market Share by WRB Type
| Barrier type | Share of new-home installations | Where it dominates |
|---|---|---|
| Mechanically attached housewrap | More than two-thirds | Volume tract building |
| Combination WRB and sheathing panels | About 10 percent | Higher-end homes and multifamily |
| Self-adhered membranes | Approaching 10 percent | Window-heavy walls and re-siding |
| Fluid-applied membranes | About 3 percent | Custom homes and complex detailing |
Mechanically Attached Housewrap Still Leads
Traditional mechanically attached housewrap, the rolled sheet stapled or nailed to the sheathing, still accounts for more than two-thirds of everything installed. The format has decades of installer familiarity behind it, a low price per square foot, and a forgiving installation window. It installs in almost any weather a crew can work in, which keeps schedules moving through shoulder seasons.
Installation quality decides how well a mechanically attached wrap performs. The material goes on horizontally, with each upper course lapping the course below it shingle-style so water runs over the laps instead of under them. Fasteners follow a schedule: staples or cap nails spaced 12 to 18 inches apart along the edges and down the studs, with seams sealed where the manufacturer requires. A wrap stretched tight tears at the fasteners, while one left too loose flaps in the wind and works holes in itself. Crews that have hung wrap for years do this by feel, which is why installer experience is the real warranty behind the material.
Why One Brand Keeps Half the Market
One brand holds nearly half of all new-home housewrap and WRB installations, a lead built on early entry and sustained education. DuPont established leadership in technology and education early and has maintained that leadership for decades, according to the market research. The lesson for competitors is that installer familiarity is a moat: crews install what they know, and changing brands means changing habits, fastener schedules, and warranty paperwork.
Technology has closed much of the performance gap between brands, but the evolution of weather-resistive barriers continues as manufacturers push air-tightness and vapor permeability in both directions. The category now spans grades from basic water shedding to air-barrier performance that supports whole-house energy modeling.
Combination Sheathing Panels Gain Ground
Combination products that merge the WRB with the structural sheathing now account for about 10 percent of new-home installations. A panel with the barrier factory-applied eliminates the separate housewrap step and seals the sheathing joints with tape instead of lapped rolls. The system closes the wall in one trade, which shortens the schedule and removes one inspection point.
Panel Performance and Installation
The trade-off is straightforward. Panels cost more per square foot than rolled wrap, but they save a labor step and produce a tighter, more uniform barrier with fewer fastener penetrations. The economics favor panels on higher-end homes and multifamily buildings, where labor savings and air-leakage performance justify the premium. Contractors weighing the switch compare installation and performance carefully, because changing systems reorders the whole exterior sequence: taping schedules, window rough openings, and siding attachment all shift.
Installers have to respect the panel system’s rules. Joints must land on framing or approved blocking, tape must be embedded with a roller, and fastener spacing follows the manufacturer’s schedule. The system only performs when the details do, which is why manufacturers train installers before they certify a crew.
Self-Adhered and Fluid-Applied Membranes Grow Their Share
Self-adhered membranes, the peel-and-stick sheets used around openings and on problem walls, are approaching 10 percent of the new-home market, and fluid-applied membranes hold about 3 percent. Both formats excel where a rolled wrap struggles: irregular surfaces, complex transitions, and the window and door perimeters that leak most often.
Hot Weather and Adhesive-Backed Membranes
Adhesive-backed products behave differently with the thermometer. On hot days, the adhesive softens and the membrane can slide or wrinkle during application, so crews work faster and roll every lap firmly. The same heat that forces careful scheduling of hot-weather concreting changes the window for peel-and-stick work, and experienced crews move membrane installation to the morning hours when the surface temperature stays manageable.
Fluid-applied products have their own temperature rules. Most require a minimum application temperature that protects cure time and adhesion, and some need the surface dry for a specified window before coating. Cold weather slows the cure of solvent-based products, which is why manufacturers publish application ranges and why crews carry thermometers on the wall.
Flashing and Detail Work Decide WRB Performance
The material is only part of the system. Research on barrier failures consistently points to details rather than sheet goods: unsealed laps, missing flashing at the base of walls, and windows installed without proper pan flashings. A premium membrane installed with sloppy transitions performs worse than commodity wrap installed correctly.
Critical Flashing Locations
- Window and door sills: pan flashing installed before the unit goes in
- Wall-to-roof intersections: step flashing integrated with the barrier plane
- Deck and porch ledgers: flashing that sheds water before it reaches the wall
- Wall bases: a drip edge or gap that keeps the barrier off standing water
- Pipe and vent penetrations: boots sealed to the barrier with approved tape
Sequence matters as much as location. Manufacturers publish flashing details for each transition, and following them in order is the difference between a wall that drains and one that traps moisture. The cheapest fix in the building is a detail done right the first time, because the expensive fix happens after the siding is on.
What Buyers and Remodelers Should Verify
For anyone buying or re-siding a house, the barrier behind the siding is invisible once the exterior is closed, so verification has to happen before that. Re-siding is the best opportunity to upgrade, because the old barrier is exposed and can be replaced at material cost while the crew is already on site.
A Buyer Checklist for the Exterior
- Confirm which WRB the house has and whether it covers the full wall plane
- Check window and door flashings during any inspection
- Ask whether the siding crew laps the barrier in the correct direction
- Verify the barrier overlaps the sill plate and foundation line
- Budget for a self-adhered membrane on the most exposed walls
In a tight market, buyers rush past the exterior because the interior looks finished. That is the wrong order: a missing or damaged barrier is a repair that happens behind closed walls, and it is far harder to fix than a cosmetic issue. Buyers competing in a sellers market should keep the wall assembly on the inspection list even when the bidding moves fast.
