Abstract
Abstract Facings for plastic foamed construction insulation board are made from paper treated with a treatment comprising about 10% to 100% of the weight of the paper including polymer, water repellant, and fire retardant. A reinforcing scrim may be combined with the paper. The treatment is applied to paper, the scrim is combined with the paper, and foam-forming liquids are applied to the paper to form a facing for a plastic foamed construction insulation board.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
114 words
For use in plastic foamed construction insulation board in which the plastic foam is formed on the facing during manufacture of the board, a flexible, thin, light weight facing comprising, (a) paper, said paper having been treated with a treatment comprising materials whose dry weight is about 10% to 100% of the weight of the paper and which treatment coats fibers in said paper with a composition which reduces the liquid permeability of fibers of said paper, tends to fill interstices in said paper, and imparts to the paper fire retardancy, water repellancy, reduced porosity, and reduced ability to transmit liquids through said paper, (b) and a reinforcing scrim adhesively bonded to said paper.
Claim 2
Dependent Claim
114 words
For use in plastic foamed construction insulation board in which the plastic foam is formed on the facing during manufacture of the board, a flexible, thin, light weight facing comprising, (a) paper, said paper having been treated with a treatment comprising materials whose dry weight is about 10% to 100% of the weight of the paper and which treatment coats fibers in said paper with a composition which reduces the liquid permeability of fibers of said paper, tends to fill interstices in said paper, and imparts to the paper fire retardancy, water repellancy, reduced porosity, and reduced ability to transmit liquids through said paper, (b) and a reinforcing scrim adhesively bonded to said paper.
Claim 3
Dependent Claim
73 words
For use in plastic foamed construction insulation board, a flexible, thin, light weight facing comprising, (a) paper, said paper having been treated with a treatment which comprises a polymer, the dry weight of such treatment being about 10% to 100% of the weight of the paper, and (b) a reinforcing scrim combined with said paper, such that liquids used in preparing a plastic foamed insulation construction board do not bleed through said paper.
Claim 4
Dependent Claim
73 words
For use in plastic foamed construction insulation board, a flexible, thin, light weight facing comprising, (a) paper, said paper having been treated with a treatment which comprises a polymer, the dry weight of such treatment being about 10% to 100% of the weight of the paper, and (b) a reinforcing scrim combined with said paper, such that liquids used in preparing a plastic foamed insulation construction board do not bleed through said paper.
Claim 5
Dependent Claim
87 words
For use in plastic foamed construction insulation board, a flexible, thin, light weight facing comprising paper, said paper having been treated with a treatment which comprises a polymer, a fire retardant and a water repellant, the dry weight of which treatment is about 10% to 100% of the weight of the paper and which treatment coats fibers in said paper with a composition which reduces the moisture and imparts to said paper reduced porosity, reduced ability to transmit liquids through said paper, fire retardancy, and water repellancy.
Claim 6
Dependent Claim
87 words
For use in plastic foamed construction insulation board, a flexible, thin, light weight facing comprising paper, said paper having been treated with a treatment which comprises a polymer, a fire retardant and a water repellant, the dry weight of which treatment is about 10% to 100% of the weight of the paper and which treatment coats fibers in said paper with a composition which reduces the moisture and imparts to said paper reduced porosity, reduced ability to transmit liquids through said paper, fire retardancy, and water repellancy.
Claim 7
Dependent Claim
71 words
A process for making a facing to be used in plastic foamed construction insulation board which comprises the steps of, selecting a paper having a weight between 10 and 40 pounds, treating said paper with a treatment comprising a material or materials which impart to the paper reduced porosity, water repellancy and fire retardancy, and imparts to the paper fibers reduced moisture permeability, and combining said paper with a reinforcing scrim.
Claim 8
Dependent Claim
71 words
A process for making a facing to be used in plastic foamed construction insulation board which comprises the steps of, selecting a paper having a weight between 10 and 40 pounds, treating said paper with a treatment comprising a material or materials which impart to the paper reduced porosity, water repellancy and fire retardancy, and imparts to the paper fibers reduced moisture permeability, and combining said paper with a reinforcing scrim.
