Box vents are not mechanical vents and work better when used with soffit ventilation. They're designed to work with open attics and do not need to be placed close to roof ridges to work optimally. They are also known as low profile vents because they are static and installed over a hole cut into the roof.

Granite. Granite is an intrusive, igneous stone usually found in the continental plates of the Earthâs crust. Igneous stones are mainly formed through volcanic material underneath the Earthâs surface, or liquid magma that has cooled and solidified.ranites are primarily composed of mica, feldspar and quartz, though additional minerals and trace elements give the stone a stunning array of possible colors. Graniteâs hardness and durability make it optimal for heavy-duty uses, such as flooring, countertops and vanities.
