Abstract
The present disclosure generally relates to formulations for, and methods of making and using, a roof ridge vent material having no or a low amount of formaldehyde. Compositions for making the material include at least one polyester fiber and a binder mix. The binder mix includes at least one acrylic emulsion, at least one fire retardant, at least one surfactant, at least one defoaming agent, and water.
Claims23
A composition comprising:
- at least one polyester fiber, and
- a binder mix comprising:
- at least one acrylic emulsion, wherein the at least one acrylic emulsion is a self-crosslinking binder;
- at least one fire retardant;
- at least one surfactant, wherein the at least one surfactant is a nonionic surfactant derived from neutrally charged long-chain fatty acids;
- at least one defoaming agent, wherein the at least one defoaming agent is present at about 0.024% to about 0.036% by weight of the binder mix, and wherein the defoaming agent is a water-based emulsion of wax and mineral oil;
- and
- water.

A roofing strip comprising:
- a base defining a plurality of recesses along a length of the strip, each recess separated from another recess by a section of the base and each recess extending across a full width of the strip;
- and
- an air permeable material received in the plurality of recesses defined in the base,
- the strip having a first side opposite a second side, wherein one of the first side or the second side has a planar surface and the other of the first side or the second side is configured to engage an uneven roof surface;
- and
- wherein the air permeable material comprises at least one polyester fiber and a binder mix, the binder mix comprising:
- at least one acrylic emulsion, wherein the at least one acrylic emulsion is a self-crosslinking binder;
- at least one fire retardant;
- at least one surfactant, wherein the at least one surfactant is a nonionic surfactant derived from neutrally charged long-chain fatty acids;
- at least one defoaming agent, wherein the at least one defoaming agent is present at about 0.024% to about 0.036% by weight of the binder mix, and wherein the defoaming agent is a water-based emulsion of wax and mineral oil;
- and
- water.
9 more elements
A method of installing a roofing strip, the method comprising:
- applying a strip to a major roof panel, the strip including at least one material comprising:
- at least one polyester fiber, and
- a binder mix comprising:
- at least one acrylic emulsion, wherein the at least one acrylic emulsion is a self-crosslinking binder;
- at least one fire retardant;
- at least one surfactant, wherein the at least one surfactant is a nonionic surfactant derived from neutrally charged long-chain fatty acids;
- at least one defoaming agent, wherein the at least one defoaming agent is present at about 0.024% to about 0.036% by weight of the binder mix, and wherein the defoaming agent is a water-based emulsion of wax and mineral oil;
- and
- water, and
- attaching a minor roof panel to the major roof panel such that the strip is positioned between the minor and major roof panels,
- wherein practicing the method results in an estimated total daily intake of up to about 25 μg/day formaldehyde.
