A ventilation screed having an upper attachment flange having a top portion and a bottom portion and at least one opening in the top portion; a drip edge protruding from the bottom portion of the upper attachment flange; a drainage cavity protrusion protruding from the bottom portion of the upper attachment flange above the drip edge, wherein the drainage cavity has an L-shaped drainage trough portion having at least one drainage opening in a bottom portion, an upper ground portion in communication with the L-shaped drainage trough portion and a drainage cavity shroud in communication with the upper ground portion, wherein the drainage cavity shroud extends past the drip edge.

Provided is a ventilation member suitable for ensuring the ventilation of a ventilation layer provided on the back side of a wall material. A ventilation member X according to the present invention is a ventilation member that can be attached to a wall material, and includes a fixed plate portion 10, a top plate portion 20, a partition plate portion 30, a bottom plate portion 40, a front plate portion 50, and a first baffle plate portion 61. The fixed plate portion 10 has a first surface that abuts against a building framework, and a second surface on a side opposite to the first surface, and includes a first end portion 13 located on one side in a state in which the ventilation member X is attached to the wall material, and a second end portion 14 located on another side. The top plate portion 20 extends from the first end portion 13 of the fixed plate portion 10 on the second surface side. The partition plate portion 30 extends from the top plate portion 20 in a direction from the first end portion toward the second end portion of the fixed plate portion 10. The bottom plate portion 40 extends from the partition plate portion 30 in a direction away from the fixed plate portion 10. The front plate portion 50 extends from the bottom plate portion 40 in a direction from the second end portion toward the first end portion of the fixed plate portion 10. The first baffle plate portion 61 extends from the front plate portion 50 to the partition plate portion 30 side. The bottom plate portion 40 has a first hole 42. A wall material construction structure Y1 according to the present invention includes such a ventilation member X.

Insulation devices, methods and related construction techniques are provided. An exemplary device may include a body having a plurality of openings defining an openwork, to allow the passage of air therethrough when placed in contact with insulation material. The device may further include a plurality of spacer struts and/or spacing depressions fixedly attached to the body. The struts may be configured to maintain a predetermined distance between a first side of the insulation material and a building surface. The body and struts act together to define and maintain a space between the first side of the insulation material and the building surface, for example, for ventilation. The building surface can be the bottom face of a roof, an insulated attic floor, wall sheathing or a soundproofed demising wall, for example. The spacer device can be capable of being transported and stored together with, or as a separate item from, the insulation material, and can also be stored in nested layers. The device can also be stored in rolled form. The openwork of the device can additionally or alternatively include a sheet of entangled net filaments or other similar material.

A vented and water control paneling has improved drainage and integrated ventilation air space. The water control paneling may be fabricated with an omnidirectional relief pattern formed on its back surface. The relief pattern spaces the vented and water control paneling away from a structure to which it is secured, thereby providing an omnidirectional drainage plane between the back surface of the paneling and the structure. The omnidirectional drainage plane provides an unimpeded ventilation and drainage path of water and/or water vapor.

An insulating siding panel comprises a backing member, a siding member, and a tongue. The backing member comprises a front face, a rear face, a top face, and a bottom face. A groove is defined in the bottom face that is adapted to receive the tongue. The siding member comprises a veneer, a bottom lip, a nailing divot, and a tongue extending upwards beyond the backing member. When panels are laid upon each vertically, the nailing divot of the lower panel may be concealed by a front section of the backing member of the upper panel.

One aspect of the invention relates to an insulation and ventilation system for a building envelope (e.g. a building wall and/or a building roof). The system includes: one or more interior building envelope layers; an insulation panel having an interior side abutting against at least one of the one or more interior building envelope layers and an exterior side having a plurality of transversely spaced and continuously longitudinally extending grooves interspaced between a plurality of transversely spaced and continuously longitudinally extending protrusions; and one or more exterior building envelope layers located exterior to the insulation panel to provide a plurality of transversely localized venting channels defined at least in part by an interior surface of the one or more exterior building envelope layers and the grooves of the exterior side of the insulation panel.

A vented and water control paneling has improved drainage and integrated ventilation air space. The water control paneling may be fabricated with an omnidirectional relief pattern formed on its back surface. The relief pattern spaces the vented and water control paneling away from a structure to which it is secured, thereby providing an omnidirectional drainage plane between the back surface of the paneling and the structure. The omnidirectional drainage plane provides an unimpeded ventilation and drainage path of water and/or water vapor.

An insulating siding panel comprises a backing member, and a siding member. The backing member comprises a front face, a rear face, a top face, and a bottom face. The siding member has an upper end, a lower end, and a nailing divot. An upper end of the backing member combines with the upper end of the siding member to form a tongue. A groove is defined in the bottom face of the backing member that is complementary in shape to the tongue. The nailing divot of the lower panel may be concealed by a front section of the backing member of the upper panel.
