The roof curb is a very important component to any commercial kitchen ventilation system as it mounts the upblast exhaust fan to the ductwork on the roof of the building. Most rooftop ventilation fans are designed for installation on top of a pre-fabricated roof curb.

Roof curbs are a popular style of restaurant ventilation system. The roof curb supports the upblast exhaust fan and connects it to the ductwork system to extract the heat, grease and cooking residues from within the kitchen.

Material
All of our metal roof curbs are made from 20 gauge, aluminized steel with continuously welded construction.

Installation
Our strong and durable roof curbs also allow for quick and easy installation. Roof curbs should be connected to the roof with at least four lug screws, anchor bolts or other appropriate fasteners. Follow the roof curb manufacturer’s instructions for proper curb installation.

It is recommended that you use an exhaust fan hinge kit when installing your exhaust fan to the top of the roof curb to allow the fan to hinge open from the top.

Cleaning
Having a hinged exhaust fan will allow for easier cleaning of your ventilation system’s ductwork from the roof down. It is important to maintain a clean duct system as to preserve the safety of the restaurant’s staff, customers and building neighbors. Not only is a hinge required by NFPA 96 fire safety standards, a hinge kit also protects the fan from damage (saving money).

Specifications
Our custom ordered metal roof curbs come in square sizes ranging from 19.5 inches to 42.5 inches and stand at 20 inches tall, the perfect height to mount the roof curb exhaust fan. It is recommended that upblast exhaust fans be installed on roof curbs that are no less than 14” above the surface.

It is important to determine the correct size you need of the custom ordered pre-fabricated roof curb before ordering. In order to figure out the proper size to order, you’ll want to measure the size of the base of the exhaust fan. The fan base will need to slip over the roof curb, so we recommend allowing 1.5” in order to also account for the hinge kit. For example, if the base of the roof curb measures at 21”, you will want to subtract 1.5” and order a roof curb that is 19.5”.

At HoodFilters.com, we pride ourselves in offering excellence in customer service and satisfaction. Any one of our friendly and knowledgeable specialists are available to help you order the roof curb exhaust fan system you need today.
