A window assembly includes a polymer (e.g., polyvinyl chloride, vinyl) window frame made and a glass unit carried by the window frame. The window frame includes a pair of jambs and an astragal that extends between and interconnects the pair of jambs. The jambs have a channel or slot sized to receive therethrough one or more end walls of the astragal so that at least a portion of said one or more end walls extend into a hollow cavity in the jambs that is in fluid communication with one or more weep holes of the window assembly. The one or more end walls of the astragal and channel or slot of the jambs define a flow path configured to channel water from the astragal, through the channel or slot in the jambs and into the hollow cavity such that said water exits the hollow cavity and the window assembly via the one or more weep holes.

The present invention provides a polyvinyl chloride-based resin molded product obtained by molding a resin mixture containing 1 to 50 parts by weight of calcium carbonate having an average primary particle size of 0.01 to 0.3 μm and 5 to 18 parts by weight of an impact modifier per 100 parts by weight of a polyvinyl chloride-based resin, wherein a Charpy impact strength at 0° C. is 20 kJ/m.sup.2 or more, and a Vicat softening temperature is 85° C. or higher, and a method for manufacturing the polyvinyl chloride-based resin molded product.

The present invention provides a door frame comprising of two piece units and the method of installment to provide connection between the casing and the frame with a self-alignment system. This is done by a tongue and groove connection and plurality of prefabricated dowels that are specially formed to engage the grooves provided in the frame through the entire attachment area of the frame units together. The door frame units are being assembled and secured together by providing a solid reinforced assembly. In the door frame system of the present invention a strong square joint can be produced by inserting dowels at critical joints which is significantly stronger fastening mechanism than other fastening means such as nails, staples, etc. Low expansion reinforced foam fills the cavities of the frame and creates a solid bond between door system and casing.

A patio door assembly includes a panel with a glass unit, and a polymer frame including a bottom member with a sill platform. A support beam is coupleable to the bottom member over the sill platform. The support beam defines a first channel between a top surface of the support beam and a platform, defines a second channel between the platform and the sill platform, a slot defined in the platform of the support beam. A structural insert is insertable in an end of the support beam and can be positioned in the support beam such that the structural insert supports a setting block for the glass unit of the panel to facilitate transferring a weight of the panel to the sill platform. The structural insert inhibits deformation of the frame when the patio door assembly is exposed to a high temperature environment (e.g., a desert environment).

A wall vent door assembly including a multi-functional hinge including flexible and resilient material extending continuously along the hinge edge of the door; one edge of the door is configured to accept and/or otherwise interface with a complimentary edge of the hinge material, and the adjacent hinge edge of the mounting frame is configured to accept and/or otherwise interface with another complimentary edge of the hinge material. Besides providing the hinge connection between the door and the adjacent frame, the flexible material also seals the interface to prevent entry of light and wind when the door is closed. The flexible and resilient hinge material also acts as a spring, exerting force to assist in the movement of the door from the closed position to open positions.

A polymer window assembly includes a polymer window frame with a pair of jambs and a sill, and a glass unit carried by the window frame. A pair of brackets are attached to the jambs proximate corners between the jambs and the sill. Each bracket has an upright member, a horizontal member orthogonal to the upright member and a hook attached to a rear surface of the upright member. The brackets attach to the jambs so that the hook extends through a hole in the jamb, the upright member is adjacent a surface of the jamb and the horizontal member is disposed above (e.g., spaced above) the sill. The brackets support and transfer the weight of the glass unit to the jambs to inhibit (e.g., prevent) the sill from bearing the load of the glass unit, thereby inhibiting (e.g., preventing) the crushing or bowing of the sill by the glass unit and thereby inhibiting (e.g., preventing) the formation of gaps in the window assembly that allow for air and/or water infiltration through the window assembly.
