Tyvek® Insulation Wrap

Home / Tyvek Insulation Wrap

Tyvek® Insulation Wrap is a high-performance, breathable weather barrier designed to protect building envelopes from air and water infiltration while allowing moisture vapor to escape. Engineered to improve energy efficiency and prevent structural damage, this advanced wrap is a trusted choice among builders, contractors, and renovation professionals for residential and commercial construction projects.

Manufactured by DuPont, Tyvek® is crafted from spunbonded olefin fibers that create a strong yet lightweight membrane, combining durability with exceptional water resistance and vapor permeability. This balance ensures that walls remain dry and healthy by blocking liquid water from entering while letting trapped moisture evaporate, reducing the risk of mold, rot, and insulation degradation.

Benefits

WATER-RESISTANT BARRIER: Blocks rain and snow infiltration while preventing wind-driven moisture from compromising the building envelope.
BREATHABLE VAPOR PERMEABILITY Allows trapped moisture vapor to escape, reducing condensation buildup and preserving insulation performance.
TEAR-RESISTANT DURABILITY Constructed with a robust, lightweight fabric that resists punctures and tears during installation and construction.
UV EXPOSURE RESISTANCE Can be exposed to sunlight for extended periods without degrading, allowing flexible installation timelines.
IMPROVED ENERGY EFFICIENCY Reduces air leaks and drafts, enhancing indoor comfort and lowering heating and cooling costs
EASY INSTALLATION Lightweight rolls and simple fastening methods speed up installation and reduce labor costs on-site.

Properties

FUNCTION: Acts as an air and moisture barrier protecting exterior walls.
PRODUCT ROLE: Energy efficiency enhancer and moisture management membrane.
BUILDING COMPONENT: Wall assemblies in new construction, renovations, and commercial buildings.

Overview

Tyvek® Insulation Wrap plays an essential role in modern building science by protecting walls from the damaging effects of water and air infiltration while facilitating the escape of moisture vapor. Unlike traditional building wraps or tar paper, Tyvek® uses advanced nonwoven technology that balances waterproofing with breathability.

The membrane helps prevent the common problems associated with trapped moisture, such as mold growth, wood rot, and insulation failure—issues that can compromise building durability and indoor air quality. Its use contributes to meeting or exceeding energy codes and green building certifications by improving the building’s overall thermal envelope.

Contractors and builders value Tyvek® for its proven track record, backed by extensive testing under Canadian building standards, ensuring reliable performance in both cold winters and humid summers. The membrane also integrates seamlessly with other moisture control products such as flashing tapes, sealants, and house wrap tapes to provide a continuous protective barrier.

Guide

Installation

Step

01

Clean and inspect the wall surface to ensure it’s dry and structurally sound.

Step

02

Roll out Tyvek® horizontally from the bottom up, overlapping rows by at least 6 inches.

Step

03

Fasten using cap nails or staples every 12–16 inches.

Step

03

Seal seams and openings with Tyvek® tape; install cladding promptly to avoid UV damage.

COMPARATIVE TESTING

Compared to traditional building papers or generic house wraps, Tyvek® Insulation Wrap delivers superior air barrier performance combined with enhanced water resistance and vapor permeability. Independent testing under ASTM and Canadian standards shows Tyvek® reduces air leakage by up to 50%, significantly improving energy efficiency and indoor environmental quality.

Its tear resistance and UV stability outperform many competitor products, reducing material waste and installation delays. These attributes translate to lower overall construction costs, fewer callbacks for moisture damage, and extended building lifespan.
