Chimney flashing A general term for flashing a chimney to cover the intersections of the chimney and install a damp proof course (DPC) Kickout flashing At the very bottom of a roof/wall intersection, the lowermost step flashing specially formed to deflect water away from the wall. Valley flashing In the valley of two intersecting roof planes.
In light-frame construction, a trimmer is a timber or metal beam (joist) used to create an opening around a stairwell, skylight, chimney, and the like. Trimmers are installed parallel to the primary floor or ceiling joists and support headers, which run perpendicular to the primary joists.
Cross-breezes work when two windows are opposite of each other. Cross ventilation is a natural phenomenon where wind, fresh air or a breeze enters upon an opening, such as a window, and flows directly through the space and exits through an opening on the opposite side of the building (where the air pressure is lower).
The stack effect or chimney effect is the movement of air into and out of buildings through unsealed openings, chimneys, flue-gas stacks, or other purposefully designed openings or containers, resulting from air buoyancy. Buoyancy occurs due to a difference in indoor-to-outdoor air density resulting from temperature and moisture differences ...
A chimney cowl or wind directional cap is a helmet-shaped chimney cap that rotates to align with the wind and prevent a downdraft of smoke and wind down the chimney. An H-style cap is a chimney top constructed from chimney pipes shaped like the letter H. It is an age-old method of regulating draft in situations where prevailing winds or ...
His house was moved several feet off its foundation by what he estimated was a 20-foot wall of water that came down the Green River, normally more than 100 yards from his house. He counted 13 ...
A breeze across the chimney should draw air into the fireplace, but the damper might too often be closed. Also the chimney may reach only the top of the barrier wall, and it may be too short to reach the fast outside air needed for the Bernoulli effect. [2] Double-insulating the dramatic windows and glass doors would reduce heating and cooling ...
The US Standard ASHRAE 62.1-2007: Ventilation for Acceptable Indoor Air Quality, only requires 4% of net floor area to be operable. This creates the potential for increased energy consumption where natural ventilation is provided by operable windows where supplemental air conditioning is provided, in addition to generally poor control over ventilation rates during hot summer or cold winter ...
