Patent Application
20150121791
The invention relates to a multi layer web frame that attaches to a wall, floor, ceiling or roof of a building or solid object. The invention provides thermal and sound insulation while assisting the management of condensation within the frame. The invention also relates to a method of assembling the items that make the multi-layer web frame.
It is known to those who are familiar with frames and panels applied to buildings as cladding, lining or cavity panels, that these panels have a protective covering which seals the panels from water. However such sealants create an impervious surface which prevents moisture from escaping from within or passing through the panels. Absence of capillaries through these panels prevents the panel from breathing, resulting in an accumulation of moisture.
In current art, panels and impervious insulation assemblies are placed within wall cavities where condensation accumulates undetected in the early life of the building. Consequently, the trapped condensation causes dampness in the adjacent frames leading to building deterioration.
Accumulation of condensation also provides moisture for moss and mildew to grow. These growths are considered major health risks to inhabitants of buildings. To compensate for this moisture accumulation, existing art includes are a number of add-on processes that include the creation of additional escape channels, using battens and furring members behind the panels. These additional processes require skilled labour, project time and costs. These add-on channels are subject to blockage from construction material and waste.
It is known to those who are familiar in the art of covering buildings and other objects that materials should be easy to handle. However, many of these existing panel systems are heavy, requiring expensive lifting apparatus to apply them to a building.
Existing composite panel systems that use insulation layers between panels, fail to provide sufficient passages within the assembly for air or moisture to pass. This lack of ventilation causes condensation.
Existing insulation systems place a metallic reflective film within a wall cavity to reflect heat back towards the cavity. In such circumstances, the air in the cavity gains heat which is reflected back into the outer wall material the main source of heat initially. This outer wall material in turn radiates heat back into the cavity. This heat compounding process continues with a resulting heat gain in the cavity air, which has no ventilation. This whole process illustrates the inadequate insulation of such art.
Existing bulk insulation products are often poorly supported within existing insulating systems. The lack of adequate and enduring support of the bulk insulation results in the fibres sagging, which eventually leaves a thick collapsed layer near the base of the panel and thin layer of bulk insulation near the top of the panel. The thin layer has considerably reduced capacity of insulation compared with the original capacity, leading to reduced heat and sound insulation after an indefinite period.
Any discussion of documents, acts, materials, devices, articles or the like which has been included in the present specification is solely for the purpose of providing a context for the present invention. It is not to be taken as an admission that any or all of these matters form part of the prior art base or were common general knowledge in the field relevant to the present invention as it existed before the priority date of each claim of this application.
The invention describes a web frame which consists of an assembly of materials that provide thermal and sound insulation, and provide passages for moisture and air to permeate. The web frame has an outer panel bonded coextensively to a first web-sandwich.
In a further embodiment of the web frame, an outer panel is bonded coextensively to a first web-sandwich, wherein the first web-sandwich is bonded coextensively to one or more web-sandwiches in series. Each web-sandwich comprises an inner panel, means bonding, surface coatings on the inner surfaces of the panels, an assembly of spacer items that separate opposing panels, and a blanket layer confined to a finite space between opposing panels.
A blanket layer is pressed between opposing panels, pinned to the opposing panel by an assembly of spacer items, which prevent the blanket layer from sagging.
The spacer items have sharpened ends that penetrate the blanket layer thereby obtaining a positive connection between spacer items and the opposing panel.
The spaces between strands and openings within the porous blanket layer provides a drainage passage within the blanket layer that allows moisture to pass through the web frame. The space ranges from 0.01 mm to 2 mm, but preferably 0.02 mm space.
In one embodiment of a web-sandwich the blanket layer is an open-weaved bulk insulation.
In a further embodiment of a web-sandwich the blanket layer is a woven fabric.
In a further embodiment of a web-sandwich the blanket layer is a non-woven fabric or batt with openings throughout the blanket layer.
In a further embodiment of a web-sandwich the blanket layer is a multi-layered mesh.
The inner surfaces of all panels are bonded to and covered with a coating or film, being selected from one or more than one of the following group:
In one particular embodiment of the web frame, the inner surfaces of the panels are coated with metallic reflective coating, which provides thermal insulation by reflection. The limited amount of heat emitted through these reflective surfaces heats the air in the confined space between panels, wherein warm air dissipates through the passages of the adjacent porous blanket.
In a further embodiment of the invention, fine capillaries exist throughout the panels and surface coverings, the capillaries providing passages through which air and moisture may pass.
In a further embodiment of the invention the panels, spacer items, means bonding, surface coverings and blanket layers are selected from a group of lightweight materials, and assembled to form a lightweight web frame. This lightweight web frame is easy to handle, and reduces application costs
In a further application of the invention, the web frame can be applied to a wall, facade, ceiling, floor, or a roof.
In further application of the invention, the web frame functions as a structural, stand alone wall.
The outer panel is made from materials that are durable and resilient and selected from one or more than one of a group of materials comprising:
The outer panel is typically 2 mm to 200 mm thick, and most preferably 5 mm to 20 mm thick.
The inner panels are made from materials that are durable, resilient and flexible, that are materials selected from one or more than one of a group comprising:
The inner panels are typically 2 mm to 150 mm thick, and most preferably 5 mm to 20 mm thick.
The opposing panels are spaced apart by a series of spacer-nodes that are arranged in an assembly of spacer items, wherein these spacer-nodes are independent and separated. The separation of these spacer-nodes is typically in a range from 20 mm to 200 mm, and most preferably 50 mm separation.
The spacer-nodes protrude from the adjacent inner panel on which they are formed. The node protrusion dimension ranges from 2 mm to 50 mm, but typically protrude 20 mm.
In another configuration, the opposing panels are spaced apart by a series of spacer-columns arranged in such an assembly that these independent spacer-columns are separated from each other. The separation between these spacer-columns is typically in a range from 20 mm to 200 mm, and most preferably 50 mm separation.
The spacer-columns butt onto and are positioned between opposing panels, the spacer-columns each being isolated Items not formed with any panel. The spacer-column length ranges from 2 mm to 50 mm, but typically 20 mm.
The blanket layer is confined to a defined space between opposing panels. The blanket layer is compressed to a thickness ranging from 2 mm to 50 mm, but typically 20 mm thick.
The web frame has a cover-sheet attached to its outer edges, around the perimeter of the web frame. The cover-sheet is made from material that is durable, flexible, weatherproof, fire-retarding and thermally reflective.
The cover-sheet extends beyond the perimeter of the web frame, wherein the extended portion of the cover-sheet is folded over and attached to the outer edges of the web frame around the perimeter.
The cover-sheet protects the outer edges of the web frame from access of moisture, pollution and external heat.
