Abstract: A ridge vent has an elongated body having a width sufficient to span the ridge of a roof along which the ridge vent is installed. Tear lines of relative weakness are formed at spaced intervals along the elongated body. The tear lines may be formed by score lines, perforations, or otherwise and are configured to allow the body of the ridge vent to be separated manually at a selected tear line by grasping the body and tearing along the tear line. Depending partitions may be disposed on the underside of the body on either side of each tear line to form end walls at new ends formed when the ridge vent is separated along a tear line.

Abstract: A rollable baffled ridge vent has a top panel with a laterally flexible central portion and edges. Substantially flat wind baffles are supported outboard of the edges and each wind baffle is formed by an array of aligned coextensive rectangular baffle sections. Each baffle section is supported by a pair of buttresses that project from beneath the top panel. Some of the buttresses also extend inwardly toward the central portion of the panel to form supports for supporting the ridge vent on a roof. The ridge vent can be fabricated in roof length sections that can be rolled into rolls with the baffle sections splaying with respect to each other to provide rollability. For installation, the ridge vent is rolled out along the open ridge of a roof and attached with nails. Superior ventilation is provided by the high net free area and flat wind baffle design of the vent while preserving the convenience of a rollable product.

Abstract: An improved thermoplastic door jamb comprises a blown thermoplastic core encased in a non-blown thermoplastic skin. A pair of aluminum reinforcing members are embedded in the thermoplastic core and are positioned and configured to receive fasteners for securing case molding and brick molding to the inside and outside edges of the jamb respectively. The reinforcing members stabilize the jamb and, in conjunction with the attached moldings, form a rigid stable structure.

Abstract: A ridge ventilation system includes a plurality of ridge vent sections joined together in end-to-end relationship covering the open ridge of a roof. Each ridge vent section has a laterally flexible central panel flanked by ventilation grids and wind baffles. Attachment means are formed on the ends of each ridge vent section for attaching the sections together and a drain trough on one end of each ridge vent section is configured to underlie the junction between two attached ridge vent sections to drain water that may seep into the junction away from the open ridge of the roof. Buttresses that support the wind baffles are configured to hold nails for use in attaching each section to a roof.

Abstract: An improved foundation vent with increased net free area is provided. The foundation vent has a frame that surrounds and defines an opening and a grill supported by the frame and spanning the opening. The grill has an inside face disposed on the inside of a crawlspace when the vent is mounted in a foundation wall and an outside face disposed on the outside of the crawlspace. A mesh screen is mounted to the frame and spans the opening adjacent the inside face of the grill. The grill is provided with projecting standoffs that support the screen at a predetermined distance from the inside face of the grill to form a plenum between the screen and the grill. A raised peripheral rim is provided on the frame and supports the peripheral portion of the screen. The spacing of the screen from the inside face of the grill and the plenum formed thereby unblocks the portions of the screen that otherwise would be blocked by the members of the grill and thus increases the net free area of the foundation vent.

Abstract: An apparatus for providing a watertight seal at the bottom corners of an entryway is provided. The apparatus includes a flexible pad at each of the bottom corners of the opening where the side jambs meet the threshold cap. The pads extend partially behind the weather strip and are formed with a projection that extends between the legs of the weather strip. The weather strip is thus reinforced and held firmly against the bottom corners of a closed door, the front of the threshold cap beneath the door, and the space therebetween. A secure watertight seal is thus created.

Abstract: An improved astragal assembly for use with a double door installation includes an astragal strip secured along the vertical edge of the inactive door. A lock block is slidably disposed in at least one end of said astragal strip and can be moved between an extended position for securing the door and a retracted position for freeing the door. The lock block has a projecting bolt receivable in a receptacle in the door frame when the lock block is slid to its extended position. A gasket is secured to the end of the lock block and the bolt passes through an opening in the gasket. The gasket engages and seals against the door frame when the lock block is in its extended position. Gaskets are also provided on the sides of the lock block for engaging and sealing against the doors of the double door installation. When the doors are closed and secured in place, the lock block and gasket assembly prevents drafts from flowing under the door installation beneath the astragal thereof.

Abstract: A continuous sidelight threshold and door sill assembly for use with entryways having at least one fixed sidelight panel and a hinged door panel comprises an extruded aluminum frame having an elongated channel and a sloped sill. A vertically adjustable threshold cap is shorter than the channel is configured to fit in and be selectively positioned at a predetermined location along the channel. A separate panel cap is also configured to fit in the channel and be selectively positioned therealong. The assembly is universally adaptable to be used either with left handed, right handed, or double sided sidelight door entryways simply by positioning the threshold cap and the panel cap at respective appropriate locations along the channel. A removable paint shield is provided to protect the threshold and sill assembly from paint and damage during construction of a building in which the assembly is installed.

Abstract: A draining threshold and door sill assembly has an elongated frame member forming an upwardly open channel and a sill that slopes away from the channel. A threshold cap is removably captured within the channel and protrudes slightly thereabove. An end cap is securely fastened to an end of the assembly and is formed with a drain trough that extends transversely beneath the end of the assembly. The drain trough has a first portion that at least partially underlies the end of the channel and extends to a mouth at the outside edge of the assembly. Rain water that seeps under the threshold cap and into the channel flows to the end of the channel and into the drain trough of the end cap, which directs the water beyond the outside edge of and away from the assembly. The threshold cap has no openings in the top thereof and is vertically adjustable in the channel by means of a set of threaded pedestals that depend from the bottom of the threshold cap and rest on the floor of the channel.

Abstract: This disclosure relates to a method and apparatus for manufacturing zinc coated steel tubing from zinc coated steel strip. The zinc lost by volatilization during welding of the seam is replaced in a two-stage metallizing process. In the first stage an aluminum alloy is spray atomized onto the tubing. The alloy contains from 0.45 to 0.95 weight percent iron, no more than 0.10 weight percent silicon, and the remainder aluminum with associated trace elements. Thereafter, in the second stage, zinc is spray atomized over the aluminum alloy-coated substrate.
