Abstract: A seamless tube useful in making a roofing batten is extruded from a polymeric material consisting essentially of a major amount of poly(ethylene terephthalate) and a minor amount of at least one polyolefin, flattened in a vacuum sizer so as to define two plies, and milled and drawn so as to orient the tube longitudinally. As milled and drawn, the tube is oriented so as to have a tensile strength of at least about 25,000 psi in a longitudinal direction. The plies are punched so as to have holes therethrough at spaced intervals along the tube. When used to make a roofing batten to coact with conventional fasteners, such as roofing screws, the tube exhibits superior characteristics of split resistance and pull-through resistance.

Abstract: An elastomeric seal for connecting two relatively movable architectural structures, such as floor sections, is constructed to optimize resistance to failure of the elastomeric element, in either adhesion or cohesion modes. An elastomeric seal, and an underlying support plate are provided with gently undulating, somewhat sinusoidal surface configuration, with the elastomeric element being of downwardly convex configuration and of relatively maximum thickness in its center, and of downwardly concave configuration and relatively less thickness in regions spaced on either side of center. Widthwise stretching of the elastomeric element tends to be concentrated in the regions of downwardly concave configuration, being thus not only distributed but also located away from areas of maximum vertical stress.

A thermal insulation compartment (126, 128) is provided between the joint elements.

Abstract: A glazing profile strip (1) which has a foot (9) with a toothing (10) for anchoring the strip (1) on a spacer (2) connected to the structure (4) of the building, has a slot (11) in that foot (9). This slot initiates at the outside (12) of the two sealing lips (6) protruding from the foot (9) and first forms a though-like enlargement (13). This enlargement serves for receiving a filler profile strip (17) that is connected to the sealing lips (6) only by thin bridges (18). The slot then continues below that enlargement by forming a narrow portion (14) having a flared mouth (141) and terminates in a larger groove (15). The narrow portion (14) is formed by two ribs opposed to each other which have a lower side (25) formed as an undercut. That side (25) serves as a rest for a head of a replacement filler profile strip which is inserted into the slot. Prior to this insertion, the present filler profile strip (17) is removed by separating its thin bridges (18) from the walls of the enlargement.

Abstract: A glazing system for a wooden door or window employs coextruded vinyl trim strips which have a planar base with flexible compression members and flexible seal tubes and a projecting barb extending from the base. The trim strips engage in kerfs in the window sash and the seal tubes are compressed against the window lights by extruded aluminum trim caps which engage with the trim strip barbs and against the sash. Sashes which have more than one light separated by a wooden muntin are glazed with a vinyl extruded muntin strip which is attached to the muntin so that a flexible seal tube which is a part of the muntin strip base overlies the glass lights on each side of the muntin. An extruded aluminum muntin cap is snap-fit to the muntin strip such that the muntin strip seal tubes are compressed against the window glass. The aluminum muntin cap and trim caps substantially cover and shield the trim strips and muntin strips from exposure to sunlight.

Abstract: The sealing device serves for tightly sealing the gap (6) between adjacent elements (1) of the inclined facade or roof against the access of water, by forming several sealing planes (A--A, B--B, C--C, D--D). To this effect a network of sealing pieces is created. These pieces each consist of a lower portion (21) and an upper one (22). The lower portion (21) also acts as a support for the elements and comprises a bearing surface (214) each between two sealing lips (212, 213). The upper portion (22) consists of a metal rail (22) and of a sealing stip (222) which overlaps the rail laterally and rest on the elements. That sealing strip which extends in the slope or direction of the fall comprises two substantially vertical webs (228). These webs form a drainage channel for water that may have penetrated, together with substantially parallel lateral sealing lips (224) which also seal the faces of the elements.

The vertical portion is formed of a pair of downwardly extending legs integrally formed with the horizontal portion. A central extent of each vertical portion includes an outwardly directed bight in frictional contact with a side wall of an associate panel. The channel member further includes an upper horizontal component in contact with adjacent plates at their exterior surfaces. The upper horizontal component is fabricated of the same material as the panels.

Abstract: In a solarium construction, glazing is supported on glazing bars to which the glazing is clamped by means of gasket strips. The glazing bars and strips, which are interconnected are divided into complementary mirror image parts. The force which is used to connect the glazing bar parts together causes the strip parts to be forced together and this displaces the strip parts more tightly against the glazing. This enables a force which is applied within the solarium to be effective externally to fasten the glazing in position.

Abstract: A retrofittable insulation system for solar rooms having glass bays supported by sills along the bottom and separated by vertically extending glazing bars. The system includes extruded, plastic double channel tracks secured to the inside of the glazing bars and extending substantially the full length thereof. An insulating shade sheet is carried by a roller supported on brackets mounted at the tops of adjacent glazing bars. The shade sheet has corded edges captured within the channels of the tracks and a batten is secured to its lower edge. Spring motors are mounted on the sill adjacent the bottom of each track, and cables connect the spring motors to the ends of the batten. The shade is operated by an actuator connected to the shade roller, which acts against the spring motors. In a preferred embodiment, the spring motors exert a pull force on the shade that varies in accordance with the force required to retract the shade which is a function of the relative position of the shade in the tracks.

Abstract: A window construction is disclosed wherein a unitary vinyl seal 36, corresponding in shape to the window sash 20 and frame 18, is employed to seal the translucent panes 28, 30, 31, etc., in position. Double-backed adhesive foam tape strips 38, 40, 42, 44, 45, 46, etc., serve to sealingly bond vinyl seal 36, 36a, and 66 to the translucent panes, the associated sash 20 and frame 18 structure. Replacement of broken panes involves cutting around the periphery of the broken pane (FIGS. 6 and 7), removing the cut segment, installing a replacement pane and sealing it in position. The same segment of vinyl seal 36 removed, or a new seal 66 cut or formed to the same dimensions as the segment cut away, is employed to seal the replacement pane 28a in position. Sealing of the new seal (FIG. 7) is accomplished by an essentially triangular strip of adhesive foam tape 68 having adhesive on all surfaces thereof. Similar replacement seals can also be formed from the embodiments illustrated in FIGS.
