A vented soffit panel is provided. The soffit panel includes a first panel section, a second panel section and a vent channel. The vent channel is positioned between the first and second panel sections and extends along a width of the soffit panel. The vent channel has a generally dove-tailed shape defined by a first sidewall extending from the first panel section at an acute angle relative thereto, a second sidewall extending from the second panel section at an acute angle relative thereto and a top wall extending between the first and second sidewalls. The top wall has at least one row of openings extending substantially along the width. The row of openings in the top wall being positioned such that when the panel is installed the row of openings are obscured from a view of an ordinary observer by at least one of the first and second panel sections.

A ventilation screed comprising: an attachment flange having a top portion and a bottom portion; a drip edge protruding from the attachment flange and a return leg that protrudes back from the drip edge, wherein the drip edge is angled downward in a first direction and the return leg is angled downward in a second direction; a drainage cavity protrusion protruding from the attachment flange above the drip edge, wherein the drainage cavity protrusion has an L-shaped drainage trough portion having at least one drainage opening in a bottom portion and a substantially vertical portion with a top end and a bottom end in communication with the bottom portion, an upper ground portion in communication with the top end of the substantially vertical portion of the L-shaped drainage trough portion extending outward from the substantially vertical portion and a drainage cavity shroud extending substantially downward from the upper ground portion.

An intumescent mesh has a flexible grid with a plurality of strands that form a series of openings in the flexible grid, and an intumescent coating applied to the flexible grid. The intumescent coating is made of an expandable graphite and a polymer-based carrier as ingredients and having an activation temperature above which the intumescent coating swells. The grid is sized such that the intumescent coating permits airflow through the flexible grid until the intumescent coating is exposed to temperatures at or above the activation temperature, whereupon the intumescent coating swells to seal the openings and prevent air flow through the flexible grid.

An exterior elevated assembly with a walking surface is described which has features for facilitating inspection of the interior support frame of the assembly. The assembly includes a support frame for the walking surface, which defines an interior space and a soffit covering an underside of the support frame. The soffit provided with an opening. A vent panel is provided for covering the opening and a vent panel retention mechanism is provided for reversibly holding the vent panel in place over the opening. Methods and kits for installing a vent panel in a soffit of an exterior elevated assembly with a walking surface are also described.
