Insultex House Wrap®

House Wrap and Insulation Wrapped Into One

What is Insultex House Wrap®?

It is a multi-ply weatherization membrane that provides a protective layer under a building’s outer covering that resists water and air infiltration, preventing mold and mildew buildup that could cause structural rotting. What differentiates Insultex™ from its competition is the fact that it offers an R-Value, the term used to measure thermal resistance, and is most commonly used when referring to the insulating qualities of a building structure, thus increasing energy efficiency.

Insultex™ is a revolutionary structured cellular fabric that incorporates countless evacuated closed micro-cells that significantly reduce heat transfer through the fabric. Insultex™ is the newest thermal insulation on the market promising to revolutionize insulation as we know it from outerwear, tents, boots, sleeping bags, coolers and now house wrap, just to name a few.

The Thinnest Insulated House Wrap with a significant measurable R-Value.

Insultex House Wrap® is
Water and Moisture-Resistant, Air and Wind-Resistant,
& UV-Resistant

Insultex protects against water intrusion that could get behind the exterior cladding which in turn can cause mold, mildew and rotting. Insultex will increase comfort in a building structure by reducing drafts and increasing its efficiency. UV inhibitors are blended into the polymeric material to protect it from harmful ultraviolet degradation.

Insultex House Wrap® protective layer is an evacuated closed-cell polyethylene composite with superior drainage and R-Value. This certified product meets or exceeds the competitions’ performance with respect to wind, air and water-resistance, moisture vapor permeability, and durability.

Insultex House Wrap Home Insulation

Insultex House Wrap® can be applied behind any exterior cladding for commercial and residental construction.

Including: EIFS & Stucco, Cement, Hardboard, Vinyl, Wood Sidings, Brick, and Stone Veneer.

  • R-6 Value Insulation

    Superior Thermal Resistance for easily-controlled internal environmental temperatures.

  • Easy Installation

    Easily bends around corners and lies flat on uneven surfaces. It is lightweight and can be easily cut for fast, efficient installation.

    Can be applied behind any exterior claddings for commercial and residential construction:

    -EIFS and Stucco
    -Cement, Hardboard, Vinyl and Wood Sidings
    -Brick and Stone Veneer
  • Superior Drainage

    Insultex easily sheds water via an integrated drainage system. It also passes the Drainage Efficiency Test in accordance with Section 4.10 of ICC ES AC235.

Why Choose Insultex House Wrap®?

Why Choose Us?

Insultex House Wrap® is made from Low Density Polyethylene. Insultex™ is the ultimate high performance alternative to other building insulation products and housewraps. Being pliable, thin, waterproof, and having an exceptional R-value, contractors and builders now choose to implement Insultex into their products because the insulation provides their products with the high thermal insulation performance without the bulk associated with many insulation products. Contractors and builders can laminate, perforate, and sew Insultex™, making it an extremely versatile material.

R-Value Tested

The majority of extensive testing has been conducted by an independent certified laboratory using an accreditation agency-approved modified ASTM-C518 protocol. Other relevant thermal tests were conducted by accredited, independent materials testing laboratories.

Water & Air Resistant

Protects the structure from water damage and wind intrusion.

UV Resistant

Insultex House Wrap is not affected by the sun's UV rays.

Moisture Vapor Permeability

Insultex House Wrap is moisture vapor-protective but breathable. Insulation should act as a barrier to keep moisture out of your home. Water and moisture can sneak in behind the barrier of your exterior cladding. Insultex offers superior water resistance, protecting against rotting and other water damage. Insultex also offers moisture permeability, which allows moisture from inside your home to permeate to the exterior of your home. This protects your home against damage from mold and mildew and eventual wood rot.


Insultex House Wrap is constructed from a tear resistant Claf (high-performance non-woven polymeric material) material. Insultex has a reputation for extreme durability. This closed-cell foam composite protects against even the most powerful wind, resisting shredding at high speeds. The insulation underneath the siding is just as important to protecting a home as its siding. Insultex protects against air infiltration while retaining permeability. Naturally occurring moisture in the air is able to escape, cutting down on condensation which can lead to serious problems. This protects both a home’s interior walls and its siding.


Insultex House Wrap Allows for light to pass through.

The Proof
