INSULATION FACING MATERIAL Z-FOLD AREA COATING

REVETEMENT APPLIQUE SUR LA PARTIE PLISSEE DU MATERIAU ISOLANT

English Abstract

Insulation facing materials for use as a protective moisture barrier facing
sheet
(vapor retarding facing) for fiberglass and other home and commercial
insulation batting
used in walls and ceiling applications, and methods of making the barrier
facing sheet.
More particularly, the invention relates to composite coextension or poly
coated
materials used for fiberglass and other possible types of insulation, and
specifically to a
coating or spray applied by any well known means to the flange or z-fold area
of the
facing materials.

Claims

Claims

1. A coextruded coated paper material used as a facing material comprising;
a first layer comprising paper;
a second layer comprising a polymer resin material;
a third outside sealant layer comprising a low melt polymer resin;
wherein all three layers are integrally bonded together; and
a coating or spray applied to a flange or z-fold area of said facing material

2. The coated paper material of claim 1 wherein said coating or spray prevents
tackiness during a hot rolling process and installation of insulation.

3. The coated paper material of claim 1 wherein said coating or spray prevents
adhesion of folded areas during a hot rolling process and during installation
of
insulation material.

4. The coated paper material of claim 1 wherein said coating or spray
comprises starch, silicone, mineral oil, or other contaminant applied to said
flange or z-
fold areas of said coextruded facing material.

5. The coated paper material of claim 1 wherein said coextruded material is
faced with a roll or batt of insulation.

6. The coated paper material of claim 1 wherein said coating or spray on said
flange or z-fold area prevents tackiness and adhesion of said z-folds during
both said hot
rolling process when said coextruded material is faced with a roll or batt of
insulation,
and during installation when said z-fold area is pulled open.

7. A poly coated paper material used as a facing material comprising:
a first layer comprised of paper;


15


a second layer comprised of poly and/or a third layer also comprised of poly;
and
a coating or spray applied to a flange or z-fold area of said material.

8. The coated paper material of claim 7 wherein said coating or spray prevents
tackiness during a hot rolling process and installation of insulation.

9. The coated paper material of claim 7 wherein said coating or spray
adhesion of folded areas during a hot rolling process and during installation
of
insulation material.

10. The coated paper material of claim 7 wherein said coating or spray
comprises starch, silicone, mineral oil, or other contaminant applied to said
flange or z-
fold areas of said poly coated facing material.

11. The coated paper material of claim 7 wherein said poly coated material is
faced with a roll or batt of insulation.

12. The coated paper material of claim 7 wherein said coating or spray on said
flange or z-fold area prevents tackiness and adhesion of said z-folds during
both said hot
rolling process when said poly coated or coextruded material is faced with a
roll or batt of
insulation and during installation when said z-fold area is pulled open to
serve as a nailer
tab.

13. A method for preventing tackiness of a z-fold or flange area of a
composite facing material comprising:
applying or spraying a coating or spray to said z-fold or flange area of said
composite facing material prior to a hot rolling process by which insulation
manufacturers adhere insulation to facing material.~

16


14. The method of claim 13 wherein said coating comprises starch, silicone,
mineral oil, or other like substance.

15. The method of claim 13 wherein said applying or spraying is comprises;
applying or spraying said coating on said z-fold or flange areas using air
jet, sponge or
other known means of application.

16. A composite facing material adhered on a non-printed side to fiberglass
insulation material after a hot rolling process comprising;
z-fold or flange areas;
said z-fold or flange areas defined as portions of pre-folded facing material
that
extend beyond the width of said fiberglass insulation material;
prior to said folding process, a portion of said facing material that
constitutes said
flange or z-fold areas is coated or sprayed with starch, silicone, mineral
oil, or any
substance that prevents tackiness of said z-fold areas or flanges during said
hot
rolling process and later during installation.


17. A method for preparing z-fold areas of flanges of a composite facing
material
comprising;
coating or spraying a portion of said facing material that constitutes said z-
fold
area or flange with a starch, silicone, mineral oil or any substance that
prevents tackiness
of said z-fold areas or flanges during a hot rolling process and later during
installation;
folding lengthwise toward a printed side of said facing material said z-fold
areas
or flanges;
folding lenghtwise again in an opposite direction from said first fold said z-
fold

17





areas or flanges toward an outer edge of said facing material.

18. The method of claim 17 wherein said coating or spray is applied by an air
jet, sponge, or other known means of application.

19. The method of claim 18 wherein said air jet, sponge, or other known
means of application does not allow said coating to be applied beyond said z-
fold are or
flange.
