A glazing fastener for mounting either rigid or flexible storm windows employs two elongated plastic strips: a channel strip having a narrow lengthwise channel, and a glazing strip having a narrow lengthwise insert flange for insertion into the channel. Walls of the channel and sides of the insert flange have pairs of spaced apart longitudinal complementary ribs sized and positioned for interengagement. In a flexible glazing strip such ribs also enable the flexible plastic to be progressively stretched for a wrinkle-free fit. The glazing strip also has a laterally extending external flange positioned to remain outside the channel for engaging the glazing sheet, either to hold a rigid glazing sheet in place or to apply tension to a flexible glazing sheet. Various embodiments of the external flange are described including an embodiment adapted for use as an independent frame in a sliding window sash. The channel strip is oriented with respect to the window so that its channel cooperates with the shape of a selected insert flange to translate forces which would otherwise tend to separate the two strips, into a force which interlock the strips more tightly together. The channel strips are provided with means for attachment to a window frame, either a flat attachment surface or a sliding-type channel for removably mounting the fastener to a T-shaped flange on a window frame.

A glazing fastener apparatus, for securing a glazing sheet across a window opening, comprising: channel means defining an elongated channel having two inwardly opposed side walls connected by a channel bottom wall, at least one of said side walls including a pair of spaced-apart, generally rounded channel ribs extending lengthwise therealong; glazing strip means for securing an edge portion of said glazing sheet to said channel means, said strip means having: a single insert flange for insertion into said channel, said flange having opposite sides, each with a pair of generally rounded flange ribs extending lengthwise therealong in spaced-apart positions for interlocking with said channel ribs when said insert flange is inserted within said channel; and an enternal flange means extending laterally from an outer portion of said insert flange for engaging said glazing sheet; said channel ribs and flange ribs being spaced apart a depthwise distance at least as great as the width of said ribs; said insert flange being sized relative to the channel to provide just enough clearance for insertion into the channel along with a flexible glazing sheet and being sufficiently rigid that, without a flexible glazing sheet in the channel, the insert flange diagonally positions in the channel to interengage one flange rib and an adjacent channel rib to secure a rigid glazing sheet under the external flange means; and the channel means and insert flange being sufficiently resilient that the insert flange and flexible glazing can be inserted into the channel without cutting the flexible glazing between said ribs; such that said glazing fastener can be used interchangeably to secure both rigid and flexible glazing sheets across a window opening.
