The Condenser - Subframes for Louvers

A frame on top of a frame? Subframes can provide easy access to areas behind your louvers. Learn more in this quick Condenser article.

Louvers are important fixtures in your building. You install them to protect interior spaces and ductwork from rainfall or other elements that could hinder your HVAC system. Louvers are typically mounted into an opening and fixed in place with various fasteners, depending on the opening substrate. Once they’re installed, louvers stay in place until they need repairs or a full replacement.

There may be situations where you might want your louver to be removeable. In certain applications, you may want easy access to a specific ventilation point, or you may want a louver to double as an entry way. For these applications, you will need a subframe.

A subframe is an auxiliary frame assembly installed in an opening. Think of it like a picture frame for a photograph. The full louver will be mounted and secured inside of the subframe, so that the frame of the louver sits in the subframe. Although it may seem superfluous, this accessory provides many options for the louver.

Subframes allow the installed louver to be removed and returned to the frame without having to fully uninstall the louver. In other words, technicians can simply pull the louver out of the subframe to get to the space behind it. This action makes it easy to service ductwork near the exterior of the building. You can also add a hinge and latch to the louver so that it can be opened like a door. This makes it even easier to service ducts.

Subframes allow easy access to ductwork and interior spaces behind the louver, but they may not always work for what you need. For example, severe weather louvers should be mounted and secured directly into the opening. Review the application and determine whether a subframe will work for you.
