Description

ROOFING UNDERLAYMENT
FIELD OF THE INVENTION
This invention relates to a roofing underlayment system useful in roof assemblies comprising at least two layers of a coated structural article which comprises a substrate having an ionic charge coated with a coating having essentially the same ionic charge, or at least one layer of such coated structural article in combination with at least one layer of felt material. The underlayment of the present invention allows roof assemblies to achieve a class B or better (Class A) rating for protection against moderate to severe exposure to fire.
BACKGROUND OF THE INVENTION
Roofing underlayment is applied to the deck of a roof before the application of roofing shingles or other roofing material primarily to shield the roof deck from moisture, both during assembly and after roof installation.
Underlayment also helps reduce "picture framing" in which the outline of deck panels caused by irregularities in the deck surface may be visible through the roofing material applied to the roof deck. Further, the roofing underlayment should be a key component of a fire rated roof assembly. The underlayment structure should assist in preventing flaming of the underside of the deck when exposed to fire on top of the roof covering assembly. Thus, the benefits of the underlayment in the roof assembly are to provide additional fire resistance and water resistance, and to provide uniformity of the appearance of the roof surface.
Conventional roofing underlayment typically comprises a dry cellulosic felt that can be impregnated or saturated with an organic material such as asphalt. When used as an underlayment, felt typically does not provide a completely flat surface, but has undulations and distortions. It may also distort under high moisture conditions. Saturated organic felt underlayment has poor fire resistance and when burned, disintegrates.
There has long been a need for roofing underlayment that will protect a roof deck from flaming, even when noncombustible roofing materials are employed as the visible roof covering. For instance, metal roofing materials, either standing seam or shingles, are typically considered noncombustible materials. However, for noncombustible metal roof coverings to achieve a Class A fire resistance rating, a '/~
inch layer of gypsum board or a layer of'/4 inch Dens-Deck board is usually required on top of the roof deck beneath the saturated felt underlayment that is under the metal roof covering. That is because the heat of a fire burning on top of roofing materials, including noncombustible metal roof coverings, passes through the material to the underlayment which is then susceptible to burning and disintegration. Thus. it has heretofore been deemed necessary to place gypsum board or Dens-Deck board on a roof deck beneath felt underlayment and noncombustible metal roofing materials, even though such boards raise the cost of the roofing materials and their application, and despite the facts that they are heavy, difficult to handle, require covering to protect from rain, and are slippery on steep slopes; because otherwise, a Class A fire resistance rating cannot be achieved.
Thus, there is a need for a roofing underlayment system which provides fire resistance (preferably Class B or better), water resistance, and uniformity of the appearance of the roof surface, but which is not heavy, difficult to handle, slippery nor overly costly.
SUMMARY OF THE INVENTION
The present invention provides an improved roofing underlayment system comprising at least two layers of a coated structural article which comprises a substrate having an ionic charge coated with a coating having essentially the same ionic charge, or at least one layer of such coated structural article in combination with at least one layer of felt material. The felt material may be comprised of cellulosic fibers, glass fibers or mixtures thereof. In addition, the felt material may be saturated with an organic material, such as asphalt. The coating of the coated structural article consists essentially of a filler material and a binder material wherein the binder material bonds the filler material together and to the substrate and wherein the coating does not bleed through the substrate.
The roofing underlayment system of the present invention allows roof assemblies to achieve a Class B or better (Class A) rating for protection against moderate to severe exposure to fire without the use of intermediate barriers such as gypsum or other noncombustible decking. In addition, the roofing underlayment system of the present invention is not difficult to handle since it is lighter in weight than other roofing underlayment systems, is not slippery on steep slopes and is not as costly as other roofing underlayment systems comprising intermediate barriers.
The roofing underlayment system of the present invention may be used with a variety of roof assemblies including, but not limited to, combustible products and noncombustible products that do not meet a Class B or better fire resistance rating. Nonlimiting examples of such roof assemblies include, Class C asphalt shingles, plastic molded or extruded shingles, non-asphalt composite shingles, rubber based shingles, steel shingles, steel standing seam roofing systems, steel corrugated panel roofing systems, aluminum standing steam roofing systems, aluminum shingles, clay tiles, light weight concrete roofing shingles and cement tiles.
DETAILED DESCRIPTION
The applicants have discovered that an improved roofing underlayment system can be made by combining at least two layers of a coated structural article which comprises a substrate having an ionic charge coated with a coating having essentially the same ionic charge, or at least one layer of such coated structural article with at least one layer of a felt material.
Examples of suitable felt material include cellulosic fibers, glass fibers and mixtures thereof. The felt material may be saturated with an organic material.
such as asphalt. Examples of such materials are disclosed in U.S. Patent Numbers 4,513,045, and 5,717,012. The texts of both of these patents are incorporated herein by reference..
The coating of the structural article consists essentially of a filler material and a binder material. For example, United Sates Patent No.
5,965,257. the text of which is incorporated herein by reference, teaches that by coating the substrate with a coating having essentially the same ionic charge, a zero bleed through product is made while using only two major ingredients in the coating. By producing a coating having essentially the same ionic charge as the substrate. a zero bleed through product may be produced having a low binder content and no viscosity modifiers.
The substrate of the structural article may be any suitable reinforcement material capable of withstanding high temperatures such as glass fibers, polyester fibers, cellulosic fibers, asbestos, steel fibers, alumina fibers, ceramic fibers, nylon fibers, graphite fibers, wool fibers, boron fibers, carbon fibers, jute fibers, polyolefin fibers, polystyrene fibers, acrylic fibers, phenol-formaldehyde resin fibers, aromatic and aliphatic polyamide fibers, polyacrylamide fibers, or mixtures thereof which may include bi-component fibers or multi-component fibers.
In a preferred embodiment, the filler employed in the coating of the structural article may be class F fly ash, class C fly ash or mixtures thereof.
Preferably, the filler is class F fly ash wherein 90% to 95% by weight of the fly ash is aluminosilicate. Such a fly ash, known as Alsil 04TR, is produced by JTM
Industries, of Kennesaw, Georgia. In an alternative embodiment, the filler may be charged calcium carbonate or ceramic microspheres, or a blend of fly ash and calcium carbonate, or a blend of fly ash, calcium carbonate and ceramic microspheres.
The table below provides, in percentages, some of the combinations of calcium carbonate, fly ash and ceramic microspheres which may be utilized as the filler component in the coating:

The microspheres may be a 50/50 ratio of 3M's W1012 microspheres and 3M's smaller diameter 6200 microspheres. Although the table shows possible combinations of calcium carbonate, fly ash and ceramic microspheres in the filler component of the coating, it is believed that any combination of these materials may be employed.
In one embodiment, the coating is prepared by using a binder material such as a high performance heat-reactive acrylic latex polymer to bond the filler materials together and to bond the filler to the substrate. Such a binder material is Hycar 2679 acrylic latex polymer supplied by B.F. Goodrich Company of Cleveland, Ohio. It is believed, however, that any linear polymer, linear copolymer or branched polymer may be useful in preparing the coating. Possible binder materials include butyl rubber latex, SBR latex, neoprene latex, polyvinyl alcohol emulsion, SBS
latex, water based polyurethane emulsions and elastomers, vinyl chloride copolymers, nitrile rubbers and polyvinyl acetate copolymers.
In a preferred embodiment, the coating may comprise nearly 85% by weight of the structural article. In that coating, approximately from 84% to 96% by weight may be filler and the remainder may be the acrylic latex binder. The filler may be approximately 50% fly ash and 50% calcium carbonate. The substrate may comprise about 15% by weight of the structural article. Glass fibers may comprise approximately 12% by weight of the article and a binder material may comprise about 3% by weight of the article. The binder which bonds together the glass fibers may be from 99% to 75% (preferably 98% to 94%) by weight urea formaldehyde and from 1% to 25% (preferably 2% to 6%) by weight standard acrylic latex.
The substrate may be coated in a variety of ways. For example, the substrate may be coated by air spraying, dip coating, knife coating, roll coating or film application such as lamination/heat pressing. The coating may be bonded to the substrate by chemical bonding, mechanical bonding and/or thermal bonding.
Mechanical bonding may be achieved by force feeding the coating onto the substrate with a knife.
Structural articles made in accordance with this invention may be of any shape but preferably, such articles are planar in shape. The substrate is coated on one side or both sides depending on the intended application.
Additionally, the structural article may be coated with a water repellent material. Two such water repellent materials are Aurape1330R and Aurapel 391 available from the Auralux Corporation of Norwich, Conn. It is believed that wax emulsions, oil emulsions, silicone emulsions, polyolefin emulsions and surfonyls as well as other similar performing products may also be suitable water repellent materials. Further, structural articles made in accordance with the invention may be coated with an algaecide such as zinc powder, copper oxide powder or the herbicides Atrazine available from e.g. Ribelin Industries or Diuron available from e.g.
Olin Corporation, an antifungal material such as Micro-Chek 11 P, an antibacterial material such as Micro-Chek 11-S-160, a surface friction agent such as Byk-375, a flame retardant material such as ATH (aluminum trihydrate) available from e.g.
AkzoChemicals and antimony oxide available from e.g. Laurel Industries and/or a coloring dye such as T-1133A and iron oxide red pigments, and other products which can impart specific surface functions. The Micro-Chek products are available from the FerroCorporation of Walton Hills, Ohio. Byk-375 may be obtained from blacker Silicone Corporation of Adrian, Mich. and T-1133A is sold by Abco Enterprises Inc.
of Allegan, Mich. The additional coatings of, e.g. water repellent material, antifungal material, antibacterial material, etc., may be applied to one or both sides of structural articles otherwise having filler/binder coatings on one or both sides of a substrate. For example, structural articles comprising substrates coated on one or both sides with filler/binder coatings could be coated on one side with a water repellent composition and on the other side with an antibacterial agent.
The substrate in the coating may be a nonwoven fiberglass mat which is desirable because it is light in weight. Fiberglass mats are also preferred as substrates because of their fire resistant nature, their resistance to moisture damage, their excellent dimensional stability, their resistance to curl with temperature changes, their resistance to rot and decay, and their ability to accept organic coatings.
As noted above, the felt material may be comprised of celluosic fibers, glass fibers or mixtures thereof, and may be asphalt saturated. In addition, other polyester or polypropylene reinforced matrixes utilized as roofing underlayments may be used. Examples of some of the various types of materials that could be used are disclosed in U.S. Patent Numbers 4,513,045 and 5,717,012, the entire disclosures of which are incorporated herein by reference.
The applicants' invention allows roof assemblies to achieve a Class B
or better (Class A) rating for protection against moderate to severe exposure to fire.
This is because in the applicants' underlayment system, the coated structural article is comprised mainly of nonflammable filler coating. Additionally, the mat which is coated by that filled coating is also nonflammable. Thus, the present invention provides a novel roofing underlayment system which is comprised of at least two layers of a coated structural article or at least one layer of such structural article combined with at least one layer of a felt material. The invention allows roofing assemblies to achieve Class A or B fire ratings without the use of intermediate barriers such as gypsum or other noncombustible decking.
In accordance with the invention, a roofing underlayment system is installed by combining at least two layers of the coated structural article or a first layer of a coated structural article adjacent to a second layer of a felt material. In a preferred embodiment, the coated structural article may be a coated fiberglass substrate made according to United States Patent No. 5,965,257. In application to the roof deck, the composite underlayment may be applied with either component adjacent to the deck. Some unique, ornamental, highly combustible roofing products may require multiple layers of the coated structural article together with one layer of a felt material to achieve a Class A or B fire resistance rating.
The composite underlayment system of the present invention may be used with a variety of roof assemblies including, but not limited to, combustible products and noncombustible products that do not themselves meet a Class A or B fire resistance rating. Nonlimiting examples of combustible products which may be used with the composite underlayment system of the present invention include Class C
asphalt shingles, plastic molded or extruded shingles, non-asphalt composite shingles and rubber based shingles. Nonlimiting examples of noncombustible products which may be used with the composite underlayment system of the present invention include steel shingles, steel standing seam roofing systems, steel corrugated panel roofing systems, aluminum standing seam roofing systems, aluminum shingles, clay tiles, light weight concrete roofing shingles and cement tiles.
The invention is further illustrated by reference to the following examples.
EXAMPLES
Burning Brand Tests:
Class A burning brand tests were conducted at U.L. Laboratories with 30 gauge galvanized steel panels on 15/32 inch thick plywood decks. The following three configurations were tested: (1) two layers of VersaShieldTM coated structural articles made in accordance with U.S. Patent No. 5,965,257 and available from Elk Corporation in Ennis, Texas were put between the deck and a steel panel; (2) one layer of VersaShieldTM was put under one layer of D226 type II-felt underlayment available from Tamko Roofing Products in Jopplin, Mo. with a steel panel on top; and (3) one layer of VersaShieldTM was put on top of one layer of D226 type II-felt underlayment with a steel panel on top. All three configurations passed the Class A
burning brand tests. The preferred embodiment was one layer of VersaShieldTM
coated structural article combined wtih one layer of 30 1b. D226 type II-felt underlayment.
When a roofing underlayment comprising just one layer of the VersaShieldTM coated structural article was tested between a deck and a steel panel, the configuration did not pass the Class A burning brand test. Similarly, when a roofing underlayment comprising just one layer of organic felt underlayment was placed between the deck and a steel panel, the configuration did not pass the Class A
burning brand test.
It should be understood that the above examples are illustrative, and that compositions other than those described above can be used while utilizing the principals underlying the present invention. For example, other sources of inert materials as well as mixtures of binders and/or additives can be used in formulating the structural articles. Other suitable types of conventional underlayment can be used in combination with the coated structural article to improve the properties of the underlayment system formed therefrom.
