The present invention relates building constructions, and more particularly to the installation of windows and other objects into building openings.
The integration of windows into walls in commercial and residential buildings has conventionally been an inefficient, under-defined process where large margins were left by the wall/panel manufacturer to allow the window manufacturer flexibility in installation. As a result, this process has been inefficient from both a time and economic perspective. Additionally, conventional integration technologies often create thermal bridges, decreasing the energy efficiency of the buildings. There is a need for panel manufacturers and window manufacturers to openly communicate, gather information, and propose other techniques that improve energy, time, and economic efficiency of the window installation process.
A gasket assembly for attaching a window having a perimeter to a panel opening having a perimeter includes an inner frame comprising a first rigid material. The inner frame can be shaped to match the perimeter of the window. An outer frame includes a second rigid material, wherein the outer frame is spaced apart by a gap from the inner frame. The outer frame can be shaped to match the perimeter of the panel opening. An elastic material is joined to a portion of the outer frame and to a portion of the inner frame, and extends contiguously and circumferentially over the gap to couple the outer frame to the inner frame. The outer frame and the inner frame are connected only by the elastic material.
The outer frame and inner frame can include gap flanges and the elastic material includes opposing lateral side portions. The gap flanges are embedded in the lateral side portions of the elastic material. The outer frame includes connecting structure for coupling of the outer frame to the panel opening. The inner frame includes connecting structure for coupling of the gasket assembly to the window. The gasket assembly is configured to support the window in the panel opening and form a seal between the panel opening and the window.
The elastic material can be hydrophobic without voids or surface defects on sealing surface. The elastic material can be at least one selected from urethanes (polyurethane, TPU), rubbers, and nylon. The elastic material can have a Durometer Shore Hardness from 20 A to 90 A.
The elastic material can have a thickness of from 0.3 cm. to 1.25 cm. The elastic material can extend laterally outward beyond the gap flanges of the outer frame and the inner frame by from 0.1 cm. to 0.6 cm. The gap flanges and the gap have a width, and the width of each gap flange can be from 1.0 cm. to 2.0 cm. and the width of each gap can be from 0.5 to 4 cm.
The inner frame can be Z-shaped in cross-section. The inner frame can include a gap flange portion, a coupling portion, and an abutment portion. The gap flange portion can include a laterally inward extending flange embedded in a lateral side portion of the elastic material. The abutment flange can include a laterally outward extending flange. The connecting structure of the inner frame can include a T-fitting for engaging a window frame of the window.
The outer frame can be L-shaped in cross section. The outer frame can include a gap flange portion and a coupling portion. A surface of the elastic material can be planar, and the coupling portion can be planar and angled laterally outward. The coupling portion can be angled laterally outward with respect to the surface of the elastic material at an angle between 0.5 and 5 degrees from of a normal to the plane of the elastic material.
The window has a weight, the gasket assembly has a width, and the elastic material has a thickness and an elastic modulus. The elastic modulus and thickness of the elastic material support the weight of the window such that the gasket assembly width varies by no more than 10% elongation of the width of the elastic material when installed.
A method of making a gasket assembly for installing an object having a perimeter in a wall panel opening, can include the step of providing a mold defining a gap configured to match the perimeter of a portion of the object to be supported in the wall panel opening. The mold has a bottom, an inner circumferential side and an outer circumferential side. Inner frame supports are attached to the inner circumferential side. Outer frame supports are attached to the outer circumferential side. An inner frame is attached to the inner frame supports. The inner frame includes a gap flange extending laterally into the gap and spaced from the mold bottom. An outer frame is attached to the outer frame supports. The outer frame includes a gap flange extending laterally into the gap and spaced from the mold bottom. An elastic material is poured into the mold to a level above the gap flange of the inner flange and the gap flange of the outer frame. The elastic material embeds the gap flange of the inner support and the gap flange of the outer support. The elastic material is cured. A gasket assembly comprising the inner frame, the outer frame, and the elastic material is removed from the mold.
The object can be a window, a Clerestory window, a fixed door, a wall-mounted air conditioner, a vent, a duct, an exhaust fan, or another object. The method can further include the step of attaching a window to the inner frame of the gasket assembly to create a window and gasket assembly. The method can also include the step of attaching the window and gasket assembly to a wall panel opening.
