Abstract

Exemplary implementations of a thermally-efficient slidable fenestration assembly are glass window systems or glass door systems having one or more sliding glass panels. The fenestration assemblies are adapted to be mounted in an architectural structure such as a building or house. Accessory channels in the fenestration framework may be provided to facilitate nail-fin, retro-fit or screen adaptors as means to attach the assembly to the surrounding architecture. Stiles, tracks and rails of the assembly are specifically configured to reduce heat transfer across the fenestration assembly, while simultaneously maintaining the structural integrity and durability of the overall assembly. Certain stile, track and rail components may comprise materials of relatively low conductivities. Preferred stile configurations include interlock elements arranged to reduce the assembly's vulnerability to tampering from a position outside of the fenestration.

Claims17

Dependent claims

A slidable fenestration assembly having a longitudinal axis, the assembly comprising:

a panel element including
(a) a glazing element being planar and having peripheral edge portions;
and
(b) an interlock stile including
(i) an outboard section having an outer facing wall and a lateral facing wall perpendicular to one another;
(ii) an inboard section being materially discontinuous with the outboard section, and having an inner facing wall;
(iii) an interlock stile glazing channel in receiving engagement with one of the peripheral edge portions and defined at least in part by mutually-opposing disposition of the outer facing wall and the inner facing wall;
(iv) an interlock first thermal break secured in coupling communication between the outer facing wall and the inboard section;
(v) an interlock second thermal break secured in coupling communication between the lateral facing wall and the inboard section;
and
(vi) an interlock element having an interlock channel with a channel opening, an interlock base wall and an interlock engagement lip in opposing disposition with respect to one another to at least partially define the interlock channel;
wherein the interlock first and second thermal breaks and the interlock element have relatively low thermal conductivities compared to the outboard section and the inboard section.
