Product Overview

This is a volume value bulk buy of the Roberts 70-105 AirGuard Premium 3-in-1 Underlayment. The bulk roll has a 3 in. core for hanging on a pole in a contractor warehouse or service van and unrolling exactly what is needed for the specific installation. Roberts AirGuard Premium 3-in-1 Underlayment is ideal for installing laminate and engineered wood floors. AirGuard provides the moisture barrier, sound reduction and cushioning, all 3-in-1, required for a proper, quality installation. AirGuard is the only underlayment manufactured with both Microban and air flow technology to inhibit mold growth. Microban inhibits the growth of odor and stain causing bacteria, mold and mildew. The air flow technology creates a pocket of constantly circulating air to further inhibit mold growth. The 8 in. overlap film protects floors from moisture. Sound suppression characteristics make AirGuard perfect for installation in multi-level buildings. For more information, please refer to the product data sheet.

Customer Reviews

AirGuard 3,650 sq. ft. 40 in. x 1096 ft. x 1/8 in. Value Mega-Roll of Premium 3-in-1 Underlayment with Microban is rated 1.0 out of 5 by 1.
Rated 1 out of 5 by from Doesn't Work As Advertised in Basement I used this vapor barrier under my laminate bamboo flooring in my basement hoping the air flow technology as described in the description: 'The air flow technology creates a pocket of constantly circulating air to further inhibit mold growth.' would provide an effective barrier while preventing moisture build up. The barrier was effective in keeping moisture from penetrating and reaching the floor, but there was definitely no air flow and moisture condensed under the barrier. The moisture was significant and while there may not be mold on the barrier itself there was definitely mold on the floor (typical musty basement smell). It was the musty odor smell that led us to remove the floor to determine the cause of the musty odor. I would not recommend this product in basements. I am still figuring out what to do in the basement, but if you are weighing options checkout delta fl vapor barrier (there is actual space under the barrier where you can see how air would flow; in hindsight the manufacture claim of air flow is ridiculous).
