An air and/or debris dam for moving coil balance assembly for a hung window is disclosed. The air and/or debris dam is located between the carrier and a mounting location of a moving coil window balance assembly. The air and/or debris dam can travel within the jamb channel of a window frame assembly to inhibit airflow and/or the deposition of dust and/or debris in the jamb channel.

A window balance may include a shoe body with an elongate portion and an enlarged portion. The elongate portion may include at least one carrier section for supporting a coil spring and an enlarged portion may include a locking element and a cam in communication with the locking element. The width of the enlarged portion may be greater than the width of the elongate portion. The spring may rest in the carrier section and may be secured to a window jamb with a fastener or a mounting element.

A window balance assembly may include a carrier, a spring element, and a mounting bracket. The spring element may include first and second portions. The first portion may be coupled to the carrier. The mounting bracket may engage the second portion of the spring element and may selectively engage the carrier. The mounting bracket may include a first mounting surface disposed at a non-perpendicular angle relative to an exterior surface of carrier when the window balance assembly is in an uninstalled configuration. The first mounting surface may be substantially parallel to the exterior surface of the carrier when the window balance assembly is in an installed configuration and the mounting bracket is disengaged from the carrier.

Systems, components, and methods for attaching insulating foam panels to a wall provide additional insulation by virtue of the low thermal conductivity of the foam material of which the panels are made. Structural elements disposed within the panels provide attachment features used for fixing the panels to the wall, and also provide a structural mounting for finishing materials that may be placed on the wall. A clip attaches to the attachment features and is then affixed to the wall. One or more shims may be attached to the clip for accommodating irregularities in the wall. The shims also may be used in a variety of additional applications where accommodation for irregularities in spacing is desired.

A window maintenance apparatus for a tilt-in sash includes a base leg for extending generally upwards from a floor towards a window. The base leg includes a first foot for resting on the floor. A hinged leg is joined to the base leg proximate an end of the base leg for extending generally downwards towards the floor. The hinged leg includes a second foot for resting on the floor. An extension tube extends upwardly from the base leg where a length of the extension tube above the base leg is adjustable. A locking mechanism locks the extension tube at an adjusted length above the base leg. A first sash support is rotatably joined at a first position on the extension tube for rotating about the extension tube from a first position to a second position for supporting the tilt-in sash in a generally horizontal position.

A curl spring sash shoe cassette improves upon the suggestions of U.S. Pat. Nos. 5,353,548 and 5,463,793 by providing a mounting bracket that holds an uncurled length of the curl spring and is securely mounted on top of the shoe cassette to maintain an assembly of the shoe body, the curl spring, and the mount during shipment to a window manufacturer. The mount can receive two mounting screws to resist torque caused by curl springs and sash weight. The shoe is also improved to facilitate removal and reinsertion of sash pins into the tilt lock cams of the shoes and ensure that shoe body halves do not rotate relative to each other when sash tilting splays the body halves apart to lock them in a shoe channel.

A pivot hinge for roof windows with a sash pivoting around the axis located between the upper and the lower member of a window, has a balancing system, which ensures the state of equilibrium of a window sash when its centre of gravity is located outside the sash rotating axis and the friction spring of the hinge is unable to hold the sash pivoted in each its position. At the same time the window fittings, its assembly, installation in a roof and its appearance remain unchanged. Also the method of separating of both hinge parts (taking a sash out of a window frame) remains unchanged.

A modular spring support mounting for a sash window spring counterbalance arrangement includes at least a first spring support mounting element and a second spring support mounting element each for supporting a respective coil spring. The first spring support mounting element includes a pair of wedged shaped cross section projections. The second spring support mounting element includes an interengagement fitting which engages the pair of wedged shaped cross section projections to in use securely interconnect the first and second spring support mounting elements together. Also a method of installing such a modular spring mounting includes the step of laterally slidingly engaging the spring mounting elements to securely interlock the elements together.
