Submerged combustion systems and methods of use to produce foamed glass. One system includes a submerged combustion melter having an outlet, the melter configured to produce an initial foamy molten glass having a density and comprising bubbles filled primarily with combustion product gases. The initial foamy molten glass is deposited directly onto or into a transport apparatus that transports the initial foamy molten glass to a downstream processing apparatus. An intermediate stage may be included between the melter and the transport apparatus. One intermediate stage is a channel that includes gas injectors. Another intermediate stage is a channel that produces an upper flow of a less dense glass and a relatively more dense glass lower flow. The upper flow may be processed into foamed glass products, while the more dense flow may be processed into dense glass products.

A gypsum board having glass fiber reinforcement. The glass fiber has sizing promoting bonding with a gypsum matrix. The glass fibers are added to the gypsum matrix cia a non-woven glass fiber mat bonded initially with a dissolvable or reversible binder to maintain the three dimensional architecture of the non-woven glass fiber mat during handling and insertion into a cast wet gypsum slurry forming a gypsum board. Upon insertion in the wet gypsum slurry, the dissolvable bond between the glass fibers in the non-woven glass fiber mat dissolves and allows the sizing coating on the glass fibers to make intimate contact with the gypsum matrix. In case of the reversible bond, the bond adhesive hydrolyzes during the gypsum board drying cycle providing intimate contact between the sizing coated glass fibers and the gypsum matrix. The non-woven glass fiber mats bonded to the gypsum matrix provides improved strength and flexure resistance of the gypsum board.

A gypsum board having roughened surface glass fiber reinforcement. The roughened surface of glass fiber is created by incorporating nano or micro particles of colloidal silica or clay or other inorganic particles in a silane based sizing composition. The sizing coating is partially or completely cured and incorporated in gypsum wet mix either as additions of chopped fibers or as placement of roughened surface glass fiber mats at selected locations within a cast gypsum sheet. The roughened surface of glass fiber with nano or micro particles compliantly bonded with silane polymer transfers load from gypsum to glass fibers providing improved strength and flexure resistance of gypsum boards.

The facing of a faced insulation layer has Z-folded, double-folded, or single-folded lateral tabs extending the length of the facing sheet along or spaced inwardly from lateral edges of the facing sheet. Each lateral tab has multiple segments. One of the segments of each lateral tab has an adhesive thereon that can be exposed and extended beyond one of the lateral edges of the insulation layer for bonding the faced insulation layer to a framing member. Where the blanket is separable into sections, the facing has pairs of separable tabs that separate when the blanket is separated to expose surfaces of the separable tabs with adhesive thereon. The adhesive may be microencapsulated or have microencapsulated constituent(s).
