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.

Abstract: A hung egress window allows the operable lower sash to travel a greater distance relative to a prior art hung window in order to give more clear space height for a given size window. This additional travel distance is achieved by lowering the location of the top rail of lower sash to be substantially below the bottom rail of the upper sash except where the seating flange of the top rail seats within a gasket lined seating pocket of the bottom rail of the upper sash. Additionally, the profile of the sill is lowered so that a portion of the flanges of the glazing pocket of the lower sash visibly extend above the sill.

Abstract: A safety gate has two frame assemblies, a shaft fixing assembly and a stretcher assembly. A relative distance between the two frame assemblies is fixed by the shaft fixing assembly first. The stretcher assembly further pushes the two frame assemblies outwardly so that the two frame assemblies tightly abut against two walls of a mounting premise and can be held on the walls securely. When the safety gate is not in use, the stretcher assembly is released to loosen the safety gate from the walls and the stretcher assembly can be moved to elsewhere. As the safety gate can be repeatedly mounted without having to readjust the relative distance between the two frame assemblies with the shaft fixing assembly, the operation of the safety gate is easy and convenient.
