Vent baffle and perforation machine

Abstract

An adaptable vent baffle mountable to an underside of a roof deck and to a wall plate of a building structure between a pair of roof rafters having a rafter spacing for permitting ventilation between a soffit and an attic space of the building structure. A main body portion has a longitudinal axis and is positioned generally on a main body plane. A spacer extends from the main body portion and a tail portion is hingedly mounted to the main body portion. The main body portion and tail portion include first and second side edges and a baffle width is defined between the first and second side edges. At least one line of weakness extends generally parallel to the longitudinal axis for modifying the baffle width to adapt to the rafter spacing. A perforating machine for forming perforated lines on the vent baffle is also disclosed.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application is a continuation-in-part application of U.S. patent application Ser. No. 10 / 811,632, filed Mar. 29, 2004 and titled, “Vent Baffle and Method of Installation”, the disclosure of which is incorporated herein by reference.BACKGROUND OF THE INVENTION [0002] The invention is in the field of building construction materials and particularly relates to attic vent baffles commonly used in residential building structures to allow ventilation flow through soffit vents into an attic space. [0003] It is known to provide attic ventilation systems to properly ventilate the attic space often found in buildings. Ventilation of the attic space is desirable to help prevent formation of condensation along the interior surface of the roof, which can damage attic insulation and the building structure itself. Proper ventilation also helps to prevent premature melting of snow accumulated on a building roof. Such premature melting can lead to ...

AI Technical Summary

Problems solved by technology

Such premature melting can lead to the formation of ice on the roof.

Such ice formations can be both a safety hazard and can lead to roof damage.

An attic ventilation system directs and controls the ventilation air flow, as otherwise uncontrolled air currents can be sufficiently strong to disturb placement of attic insulation, blowing the insulation about to create areas which are not properly insulated.

Uncontrolled air currents circulating in the attic space can also negatively affect performance of the attic insulation by promoting increased convective heat transfer along the top surface of the insulation.

The installation process is thereby complicated by the need to install two separate components and also by the need to fold the block component along multiple fold lines.

In order to install the ventilation panel of Best, it is necessary that the sheet be cut and folded at multiple locations, thus necessitating a relatively complicated and time-consuming installation process.
