BAUTEX AIR & MOISTURE BARRIERS

CONTINUOUS AIR & MOISTURE CONTROL

Bautex AMB 20 Air and Moisture Barriers pro­vide an air­tight and extreme­ly ener­gy-effi­cient build­ing enve­lope that will meet and even exceed the code require­ments of res­i­den­tial con­struc­tion projects across all cli­mate zones in the Unit­ed States.

Flu­id applied air and mois­ture bar­ri­ers like Bau­tex AMB 20 are installed quick­ly and with min­i­mal labor. Bau­tex AMB 20 is spe­cial­ly for­mu­lat­ed to install quick­ly and com­plete­ly cov­er the rougher tex­ture of the Bau­tex Wall Sys­tem, pro­vid­ing long-last­ing build­ing pro­tec­tion and ener­gy effi­cien­cy.

Bau­tex AMB 20 air and mois­ture bar­ri­ers are water-based for­mu­la­tions that are avail­able in both water vapor-per­me­able (AMB 20-WP) and non-per­me­able (AMB 20-WN) options, giv­ing archi­tects the flex­i­bil­i­ty to meet the spe­cif­ic require­ments of their projects.

Air
Meets the most stringent air permeance and leakage testing protocols for air barrier materials and assemblies.
Water
Robust and resilient protection from wind-driven rain and other sources of moisture.
Water Vapor
Available in vapor-permeable and non-permeable formulations for maximum versatility.

BENEFITS OF BAUTEX AMB 20

FEATURE BENEFIT
Water-based No harmful odors or solvent fumes and no chemical needed to clean equipment.
Single Component Allows for fast and easy application. Creates a monolithic protective barrier.
Vapor-permeable option Prevents moisture from being trapped in the wall cavity by allowing controlled diffusion of water vapor inside framed wall assemblies.
Long-term UV exposure Can be left exposed to UV up to 12-months, allowing for greater flexibility during construction.d
Excellent adhesion Adheres to all common building surfaces, including sheathing, concrete, masonry.
Very low VOC Water-based air and moisture barrier has VOC content less than 100 g/L.

INSTALLATION OF BAUTEX AMB 20

The Bau­tex AMB 20 prod­uct is applied as a single-component system applied direct­ly to the exte­ri­or wall sub­strate in a sin­gle 40-45 mil wet coat. Bau­tex AMB 20 can be applied quick­ly and effi­cient­ly to Bau­tex Block, con­crete, con­crete block (CMU) or exte­ri­or sheath­ing mate­ri­als using air­less spray equip­ment, paint rollers, or with trow­els.

Bau­tex AMB 20 can be installed in a sin­gle spray appli­ca­tion, but roller appli­ca­tion will require two coats to get to the cor­rect 20-25 dry mil thickness. AMB 20 is applied at 30-40 square feet of wall per gallon of mate­r­i­al depend­ing on poros­i­ty of the wall sub­strate (Bau­tex Block @ 30 sf/​gal and Sheath­ing @ 40 sf/​gal).

Bau­tex Air and Mois­ture Bar­ri­er AMB 20 can be pur­chased in 5‑gallon (18.9 liters) pails and 55-gal­lon (208.2 liters) drums.

BAUTEX AMB 20 TESTING

Fluid-Applied Air & Moisture Barrier

Bau­tex AMB 20 Air and Mois­ture Bar­ri­ers have been lab­o­ra­to­ry test­ed to meet the min­i­mum stan­dards for wall air bar­ri­er assem­blies as pre­scribed by the Air Bar­ri­er Asso­ci­a­tion of Amer­i­ca.
