EXHAUST VENTS

Lambro produces exhaust vents, which are crucial parts of kitchen, bathroom, and dryer HVAC ventilation systems. Our exhaust vent products may be listed as roof vents, hood vents, under eve vents, or caps on our site.

When searching for “exhaust hoods,” “hood vents,” or “vent hoods” on Google, one may come across pages about kitchen range hoods, which are hood canopies that remove smoke and odors from cooking ranges.

However, these terms also have a different meaning in regards to ventilation systems for kitchens, dryers, and bathrooms, referring to the final component of the venting system that allows air to escape through an exterior wall or roof. These types of exhaust vents are often referred to as wall/roof caps, roof/wall vents, dryer vent hoods, or simply as a vent hood or hood vent.

Plastic & Aluminum Roof and Wall Exhaust Vents

Exhaust Vents Bathroom Roof

Plastic & Aluminum ROOF Exhaust Vents

Bathroom exhaust vent wall and roof caps along with the necessary ducts are a critical part of a home’s ventilation system. Yet having a bathroom intake and / or exhaust fan is often overlooked, particularly in you live in an older rental, condo or coop apartment where building codes do not require it as long as you have a window in the bathroom. For new homes, an exhaust fan in the bathrooms is a must.

By removing moisture vapors generated from bathing and other activities, as well as keeping the bathroom fresh, a bathroom exhaust fan can help prevent serious damage to drywall, wallpaper, window coverings, and cabinetry as well as mold issues. A bathroom exhaust fan keeps the bathroom dry and odor-free. Models are available that mount in the ceiling, a wall or the window, but all must vent outside via an exterior wall or through the roof.

The most common option for bathroom exhaust fan venting is to an exterior wall. The second most common is the roof vent installation. Bathroom exhaust fan venting installation at the soffit, the underside of a roof’s overhang, is less often utilized. Check with your local building code regarding a soffit installation because not all municipalities allow this venting option.

Bathroom Wall Cap Vent Kits w/ Parts

Unlike dryer ducts, bathroom ducts kits interior surfaces of bathroom ducts can be ridged or smooth because metal, plastic, and aluminum flex ducts are permitted for bathroom venting, Smooth surfaces aren’t not required for the bathroom ducts as they are for dryer ducts. Pooling

of condensation is more of a concern. For bathroom vents, there are no explicit length and diameter requirements in the IRC (International Residential Code). FYI: Clothes dryer ducts can be used for a bathroom / shower fan’s exhaust duct, but not necessarily vice versa. Residential Code (IRC) SECTION M1502 CLOTHES DRYER EXHAUST guidelines state that “Exhaust ducts shall be constructed of minimum 0.016-inch-thick (0.4 mm) rigid metal ducts, having smooth interior surfaces, with joints running in the direction of air flow. Exhaust ducts shall not be connected with sheet-metal screws or fastening means which extend into the duct“. In other words: flexible, ribbed vents are not allowed for dryer ducts.

Typical kit features include:

· Opening/closing damper prevents outside elements from entering the vent
· Removable screen
· UV inhibitor used to help prevent the premature fading of outside exhaust vent
· Include either hood or cap vents or louvered vents with tail pipe, a trim plate and some type of clamp
