What Does Roof Curbs Mean In Construction?
In construction, roof curbs refer to raised frames that are installed on a roof to provide support for equipment such as air conditioners, exhaust fans, and ventilation systems.
The frame is usually paired with a flashing system that seals the roof against water intrusion and ensures that the equipment will sit securely on top of the roof.
Roof curbs also create a level surface that allows for easy installation of these devices. They are typically made from metal or wood and come in standard sizes to accommodate different types of equipment.
By providing a secure mounting solution for necessary pieces of equipment, roof curbs facilitate proper installation and help keep roofs safe from water damage.
What Does A Roof Curb Look Like?
A roof curb is a raised structure in the shape of a rectangular box that sits on top of a building’s roof.
It typically contains an opening for an item such as a fan, vent, or exhaust stack to be fitted into.
The sides and ends of the structure are usually made from metal, although some may be constructed with wood.
Roof curbs are designed to provide stability during extreme weather conditions and protect the attached equipment from weakened support due to strong winds and storms.
They also help decrease noise transmission while also providing additional insulation that helps reduce energy costs due to fluctuating temperatures between the inside and outside of the building.
What Is The Difference Between A Roof Curb And Dunnage?
A roof curb is a type of frame that is mounted at the edge of a roof to provide protection for mechanical systems, such as HVAC units and rooftop fans.
It also helps to support and secure the unit in place so that it does not become damaged due to wind or other adverse weather.
Dunnage on the other hand is material used to protect equipment from damage during shipping and handling.
It includes items such as padding, crates, boxes, straps and pallets that can be used to cushion products between them or restrain them in place.
Both roof curbs and dunnage are important components used to ensure safety when dealing with machines on roofs or fragile goods during transit.
How Do You Measure A Roof Curb?
Measuring a roof curb involves measuring two distinct entities: the base of the curb, and its top lip.
To measure the base of the curb accurately, use a tape measure to record its width and length at different points; then, on a graph paper (or any other kind), plot out these points according to their measurements.
Similarly, you should also make marks along the bottom edge of the roof that correspond to each point for reference purposes.
Next, to measure the top lip of the roof curb, take measurements at various angles with your tape measure until it meets with exact dimensions that match those marked on your graph paper.
Finally, connect all points together and transfer them onto your roof’s surface to complete your measurement process.
What Are HVAC Roof Curbs?
HVAC roof curbs are metal structures which provide a platform for mounting HVAC units to the roof of a building.
They provide an optimal connection between the equipment and the roof, seal off openings from debris, allow for proper drainage and ventilation, and provide support for ducts.
They also assist in providing overall structural integrity when installed properly. Most notably, they can help protect HVAC systems from wind gusts by acting as a barrier and providing stability to the entire unit.
HVAC roof curbs are typically constructed out of galvanized steel, aluminum or stainless steel material to ensure their durability in extreme weather conditions such as snow or high winds.
What Are RTU Roof Curbs?
RTU roof curbs are a type of raised structure that is installed onto a rooftop and used to provide mounting points for stationary air-conditioning, heating and ventilation (HVAC) equipment.
They are built to house the internal components of HVAC systems, such as blowers, compressors, evaporators, condensers, dampers and other necessary components.
RTU roof curbs also protect these components from adverse weather conditions while allowing sufficient air intake and exhaust air discharge.
Depending on the size of the equipment being mounted to the rooftop, custom-made RTU roof curbs can be designed to meet specific needs.
These structures can be made out of galvanized steel or aluminum and be designed with any slope or pitch needed to accommodate any level rooftop surface.
