A prefabricated wall panel has a precast body including at least one decorative design element. In addition, the wall panel includes a mounting element having a first end embedded in the precast body and a second end projecting from the precast body. A groove is formed between the precast body and the second end of the mounting element along a first edge of the precast body. A tongue is formed along a second edge of the precast body opposite the first edge. The tongue and groove cooperate to allow prefabricated wall panels to be more easily installed on a support substrate.

A roofing shingle (74) includes an asphalt-coated sheet (18) having a tab portion (78) normally exposed on a roof and a headlap portion (76) normally covered-up on a roof. The headlap portion has a lower zone (76A) that extends longitudinally between a first end (74A) and a second end (74B) of the roofing shingle adjacent the tab portion, and an upper zone (76B) adjacent the lower zone. At least a portion of the asphalt-coated sheet has granules adhered thereto. A reinforcement member (19) is adhered to the lower zone of the headlap portion.

An apparatus for manufacturing high quality glass wool fibers, and more particularly to a spinner including a radiation shield is disclosed. The spinner includes a number of radiation shield positioned beneath the spinner base and decreases the temperature gradient along the peripheral sidewall of the spinner and improves the quality of the glass fibers. One suitable material for the radiation shield is a high temperature nickel alloy.

A method for dispensing or depositing particulate material includes accumulating particulate material in a nozzle having an opening at the bottom for discharging the particulate material, and applying positive air pressure to a buffer chamber positioned in communication with the accumulation of particulate material to start and control the flow of particulate material through the opening and applying negative pressure to the buffer chamber to stop the flow of particulate material. An unobstructed interface can exist between a surface of the particulate material and air in the buffer chamber. In one embodiment, roofing shingle granules are applied intermittently to a moving coated asphaltic sheet through a slot to form strip roofing shingles.
摘要:
A method and apparatus for applying granules to a coated asphalt sheet to form at high production speeds a variegated pattern having uniform edges between areas of different colored granules. Granules of a first color or color blend are applied to spaced first areas on a moving, tacky, asphaltic strip by dropping the granules onto the moving strip. The leading and/or trailing edges of each granule drop are trimmed off by cutting or deflecting to provide predetermined sharp leading and/or trailing edges to the first areas. Granules of a second color or color blend are then deposited on the strip by dropping on tacky second areas between the spaced first areas. If desired, one or both edges of the second color granule drops also may be trimmed, the second color granules may be deposited on only a portion of the tacky strip areas between the spaced first areas, and additional color granules may be applied to the remaining tacky areas to form shingles with three or more colored areas.
摘要:
The method for applying granules to a moving coated asphalt sheet includes selecting blend drop areas on the sheet, the remainder of the sheet comprising background areas, depositing background granule drops on portions of the background areas such that the background granule drops have generally sharp leading edges which define upstream edges of the blend drop areas and have generally fuzzy trailing edges, depositing blend drops on the blend drop areas such that the blend drops have generally sharp leading edges and generally fuzzy trailing edges which overlap the background granule drops, and then depositing background granule drops on remaining portions of the background areas. The generally sharp leading edges of the background granule drops define the trailing edges of the blend drops so that when blend drops which overlap the background granule drops are removed by inverting the sheet, blend drop areas having sharp leading and trailing edges are produced.

A method and apparatus for heating fibrous mineral insulation material comprises an oven divided into zones, a conveyor for carrying the insulation material through the oven, means for directing hot gases into contact with the insulation material in the first oven zone, first heating means for heating the hot gases, and second heating means, distinct from the first heating means and positioned upstream from the first oven zone for heating the conveyor.
摘要:
A roofing shingle is provided. The roofing shingles includes an overlay sheet including a headlap portion and a tab portion and an underlay sheet secured to the overlay sheet such that a region of the underlay sheet overlaps a region of the headlap portion of the overlay sheet. A reinforcement material is secured to the headlap portion of the overlay sheet. The reinforcement material is configured to improve nail pull-through. The reinforcement material extends beyond the overlapping regions of the headlap portion and the underlay sheet a distance of about 0.12 inches or less.
摘要:
A method of manufacturing a roofing shingle includes applying an asphalt coating to a substrate to define an asphalt coated sheet, the asphalt coated sheet including a headlap portion and a tab portion. Reinforcement material is applied from a spool to the asphalt coated sheet, wherein the reinforcement material is wound in a waywind pattern on the spool. The reinforcement material is then secured to the headlap portion of the asphalt coated sheet.

A roofing shingle is provided. The roofing shingle includes an overlay sheet including a headlap portion and a tab portion and an underlay sheet secured to the overlay sheet such that a region of the underlay sheet overlaps a region of the headlap portion of the overlay sheet. Said underlay sheet has a substantially uniform thickness. A reinforcement member is secured to the headlap portion. The reinforcement member is formed from a material selected from the group consisting of paper, film, scrim, woven, and non-woven material. The reinforcement member and the portion of the headlap portion to which the reinforcement member is secured to improve nail pull-through. At least some of the reinforcement member does not overlap the overlapping regions of the headlap portion and the underlay sheet. Said reinforcement member provides said overlay sheet with a non-uniform thickness.
