Allow air into your building while prohibiting water and debris. There are several levels of water protection available, so you can use our Guide to determine the most cost effective solution for your application.
In selecting louvers and vents, consideration for your application is critical to your project success. Metal louvers are designed to allow air into the building while keeping out unwanted elements. Improper louver selection may lead to water leakage.
To assist with product selection, each louver model is listed below with optional selections by application, free area, or cost. If you are looking for products not listed, call us. We also offer louvered equipment screens and sunshades made from aluminum with various finishes to fit your project requirements.
Gain the utmost protection against water penetration by using one of our Wind Driven Rain Louvers. These louvers will protect your building from water damage, even under heavy wind and rain conditions.
Any of our louvers can be modified to handle higher wind loads (within limits). However, if you are in Florida or other coastal states with hurricane force winds, use one of our Hurricane Louvers to gain the highest levels of protection.
Louvers are commonly specified in project documents under these divisions:

Apprearance:
Suggestion: Model E2JS, E4JP, E6JP
The louver appearance should play a significant role in louver selection. It is often ignored in favor of "function over form". However, with so many high performance louvers available the appearance can now be a major consideration. For example, if your louver heights are small, you will want a narrow blade spacing. This will allow more blades in the frame and improve the appearance.
Special shapes:
Suggestion: Model E4JP
Use non-drainable louvers (models with J blades)- To view common special shapes click here. Use narrow blade spacings so the appearance will be more uniform (especially in short height louvers). Use high free area louvers - many of the special shapes have restricted free areas due to angles or rounding. A higher free area louver will help combat this loss of free space. E4JP, E6JP, E6JN
