Mounting arrangement for a foundation wall vapor barrier
View Patent ↗A vapor barrier for mounting and sealing on a foundation wall using adhesive. The vapor barrier includes a moisture impervious sheet having a first exterior side surface arranged to extend adjacent to and downward along the foundation wall when mounted. An adhesion strip is secured to the first exterior side surface being adapted to absorb an adhesive placed on the foundation wall for securing the moisture impervious sheet to the foundation wall. The adhesion strip comprising a porous synthetic fibrous web capable of distributing the adhesive completely through the adhesion strip to the first exterior side surface of the moisture impervious sheet during mounting to the foundation wall so that an air and moisture tight seal is formed between the foundation wall, the adhesion strip, and the moisture impervious sheet.
1. A vapor barrier for mounting and sealing on a foundation wall using adhesive, said vapor barrier comprising:
a moisture impervious sheet having a first exterior side surface arranged to extend adjacent to and downward along said foundation wall when mounted;
an adhesion strip secured to said first exterior side surface absorbing an adhesive placed on the foundation wall for securing said moisture impervious sheet to the foundation wall;
wherein said adhesion strip comprises a porous synthetic fibrous web, and wherein said adhesive is distributed completely through said adhesion strip to said first exterior side surface of said moisture impervious sheet when mounted to said foundation wall defining an air and moisture tight seal between the foundation wall, said adhesion strip, and said moisture impervious sheet.
2. The vapor barrier of claim 1 , wherein said porous synthetic fibrous web consists of non-woven hydroentangled spun-lace PET polyester fibers entangled in both a vertical and horizontal direction to promote strength and durability.
3. The vapor barrier of claim 1 , wherein said adhesion strip is selected with a weight in the range of 5-300 grams per square meter providing a void volume to facilitate absorption of said adhesive through to said moisture impervious sheet.
4. The vapor barrier of claim 1 , wherein said moisture impervious sheet is selected from the group consisting of plastic film sheeting and rubberized sheeting.
5. The vapor barrier of claim 4 , wherein said moisture impervious sheet consists of a solid single layered vinyl sheet.
6. The vapor barrier of claim 1 , wherein said adhesion strip is secured to said first exterior side surface of said moisture impervious sheet using an adhesive selected from the group consisting of water-based, solvent based, PUR, silicone, epoxy, acrylic, conventional or cross linkable hot melt adhesive, and thermoplastics.
7. The vapor barrier of claim 1 , wherein said adhesion strip is secured to said first exterior side surface of said moisture impervious sheet using an adhesive film carried on a back side of said adhesion strip.
8. The vapor barrier of claim 1 , wherein said adhesion strip is secured to said first exterior side surface of said moisture impervious sheet using a double-sided adhesive tape.
9. The vapor barrier of claim 8 , wherein said double-sided adhesive tape includes a dry mount adhesive on at least one side for bonding to said adhesion strip.
10. The vapor barrier of claim 1 , wherein said adhesion strip is selected from the group consisting of woven and nonwoven synthetic fabric materials.
11. The vapor barrier of claim 1 , wherein at least one of said adhesion strip and said moisture impervious sheet includes at least one of a fire retardant and a antimicrobial treatment.
12. The vapor barrier of claim 1 , wherein said adhesion strip ranges in thickness from approximately 1-20 mil to support said moisture impervious sheet and so that said adhesive is absorbed completely through to said moisture impervious sheet.
13. A method of installing a vapor barrier to a foundation wall comprising the steps of:
providing a moisture impervious sheet;
non-releasably bonding an adhesion strip to a first exterior side surface of said moisture impervious sheet, wherein said adhesion strip comprises a porous synthetic fibrous web absorbing and distributing an adhesive completely through said adhesion strip to said first exterior side surface of said moisture impervious sheet so that said adhesion strip supports said moisture impervious sheet in a vertical hanging arrangement;
applying a bead of adhesive to said foundation wall;
aligning said moisture impervious sheet to said foundation wall so that said first exterior side surface extends adjacent to and downward along said foundation wall;
pressing said adhesion strip into said bead of adhesive so that said adhesive is absorbed and extends through to said first exterior side surface of said moisture impervious sheet forming an air and moisture tight seal between said foundation wall, said adhesion strip, and said moisture impervious sheet.
14. The method of claim 13 , including the step of providing said adhesion strip consisting of non-woven hydroentangled spun-lace PET polyester fibers entangled in both a vertical and horizontal direction to promote strength and durability.
15. The method of claim 13 , including the step of selecting said adhesion strip with a weight in the range of 5-300 grams per square meter providing a void volume to facilitate absorption of said adhesive through to said moisture impervious sheet.
16. The method of claim 13 , including the step of selecting said moisture impervious sheet from the group consisting of plastic film sheeting and rubberized sheeting.
17. The method of claim 13 , including the step of providing said adhesion strip having a thickness in the range of approximately 1-20 mil to support said moisture impervious sheet and so that said adhesive is absorbed completely through to said moisture impervious sheet.
18. The method of claim 13 , including the step of non-releasably bonding said adhesion strip to said first exterior side surface of said moisture impervious sheet using an adhesive selected from the group consisting of water-based, solvent based, PUR, silicone, epoxy, acrylic, conventional or cross linkable hot melt adhesive, and thermoplastics.
19. The method of claim 13 , including the step of applying an adhesive film to a back side of said adhesion strip for non-releasably bonding to said moisture impervious sheet.
20. The method of claim 13 , including the step of applying a double-sided adhesive tape to a back side of said adhesions strip for non-releasably bonding to said moisture impervious sheet, wherein said double-sided adhesive tape includes a dry mount adhesive carried on at least a first side bonding to said adhesion strip, and a second side carrying an adhesive selected from the group consisting of a pressure sensitive adhesive, heat activated adhesive, and solvent activated adhesive.
