Description

The present invention relates to an eave system comprising of fascia and bracketing to seal the outer under section of a building roofline, commonly known as the eave, to protect it against the elements. In particular, the system can be used to seal an eave of the type that protrudes from the perimeter wall of a building and extends beneath the building roofline.

BACKGROUND [0002] Rising building and constructions costs, together with an increase in consumer demand for environmentally sustainable products, has led to an increase in demand for socially acceptable and economical products for use in the construction industry. Builders are demanding lower labour costs, lower material costs and aesthetically acceptable and environmentally sustainable products that can be quickly and efficiently installed onto a building to keep labour costs down. Furthermore, in highly temperate weather zones such as high fire areas and cyclone areas, strict building codes have resulted in an increased demand for fire resistant and cyclone graded materials to be used within the construction industry.

[0003] A known product that is used to seal the eaves of a building roofline comprises cement sheeting that is generally available in two sizes, and arrives at the construction site in sheets of these sizes. A smaller size sheet is intended to fit between an outer perimeter of a building, for example a brick or weatherboard wall, and an eaves fascia installed at the roofline. A larger size cement sheet is intended to fit between a window or door in the outer perimeter wall and the eave fascia. The cement sheets usually have to be templated and cut on site to fit a particular building. This is time consuming, laborious and potentially dangerous. The cement sheets must be kept free of moisture during the cutting and installation process. To obtain a continuous run of the cement sheets across the length of the building, plastic strips or joiners are used to join or abut adjacent cement sheets. Once the cement sheeting is in place at the roofline, a carpenter must work around the perimeter of the construction and nail on a timber strapping which conceals the joint of the cement sheet to the construction material (e.g. brick or weatherboard). Once the eaves assembly is complete, a painter is then required to paint the eaves. The known system can therefore require three different tradesmen to complete the eaves; a builder for

2014206201 25 Jul 2014 installing the eave fascia, a carpenter to construct the eave panels and associated joinery/strappings and the painter to apply the paint finish. The process can be time consuming, expensive and inefficient.

OBJECT [0004] It is the object of the present invention to substantially overcome or at least ameliorate one or more of the above disadvantages.

SUMMARY [0005] There is disclosed herein an eave system for sealing a fascia arranged at the roofline of a building roof space to a perimeter wall of the building, the roof space having at least one rafter extending from a roof beam of the roof space to the fascia, the system comprising:

an eave panel arrangeable to extend between the fascia and the perimeter wall; a bracket assembly installable on the rafter to support the eave panel at the roof line; and an eave trim arrangeable adjacent the perimeter wall between the bracket assembly and the eave panel.

[0006] An advantage of the system is that it provides an integrated means of sealing a building eave against the elements that can be quickly and easily installed at the same time as the building fascia and guttering, reducing labour costs and time.

[0007] Preferably, the eave system components are made of metal, even more preferably steel.

In an alternative embodiment, the eave components are made of plastic. The system components can be engineered or treated as required to comply with strict building codes. The system is therefore more environmentally sustainable that the known cement system.

[0008] Preferably, the bracket assembly includes a fascia bracket for supporting the fascia. Preferably, the fascia bracket is adapted for engagement with the fascia and for attachment to a fascia end of the rafter. Preferably, the fascia bracket comprises a generally rectangular plate having at least one fascia protrusion for engagement with the building fascia and a panel tab arrangeable at an angle of about 90° to the rectangular plate for attachment of the fascia bracket to the eave panel.

8940440_1:DJM

2014206201 25 Jul 2014 [0009] Preferably, the bracket assembly includes a hanging bracket for supporting the eave panel adjacent the perimeter wall. Preferably, the hanging bracket comprises an elongated strip having a generally L-shaped cross-section. Preferably, the hanging bracket is adapted for attachment at an end thereof to the rafter at a distance spaced from the fascia end thereof.

[0010] Preferably, the bracket assembly includes an elongate support bracket for attaching the hanging bracket to the fascia bracket at the roofline. Preferably, the support bracket comprises of an elongate strip having an insulating material at an underside thereof. Preferably, the insulating material is an open cell foam pad. The insulating pad insulates the eave system against noise, in particular wind tunneling through the gap between the eave panel and the support bracket once the eave system is complete and also cushions against movement of the bracket assembly and the eave panel relative to one another.

[0011] Preferably, the eave trim comprises an elongate strip having an upper lip angled at about 90° thereto. Preferably, the elongate strip includes an insulating material at an underside thereof. Preferably, the insulating material is an open cell foam pad. The insulating pad insulates the eaves system against noise, in particular wind tunnelling through the gap between the eave panel and the hanging bracket once the eaves assembly is complete and also provides cushioning against movement of the bracket assembly and panel relative to one another.

[0012] Preferably, the eave panel is generally rectangular or square and includes a rebate on opposing sides thereof for the attachment of the eave panel to another eave panel. Preferably, the eave panel includes an upper lip angled at about 90° to the plane of the panel for engagement with the building fascia. This adds to the strength of the panel fitting.

[0013] Preferably, the eave panel is power coated according to a desired finish.

[0014] Preferably, the eave panel includes one or more ventilation holes.

[0015] Preferably, the eave system further comprises a window/door infill panel. The infill panel comprises a rectangular panel adapted to fill a gap between the eave panel and a window or door revel at the perimeter of the building.
