Q: Can I get a 20-year warranty on Kynar paint on aluminum?
A: In most instances, yes. However, due to the many variables (color, product, product use and location) consult the factory.
Q: Can I get a flanged frame on Miami-Dade models?
A: Flange frame is not available on the ESD-603D series. Flanges are optional on the ESS-501D and EVH-602D series. Flanges are standard (only option) on ESD-635D and EHH-601D series.
Q: Can I get electric or pneumatic actuators to operate the damper that is incorporated in the design of the ESD-603D, ESD-635D or EVH-602D?
A: Absolutely! As you know, the default standard for Greenheck is to supply a manual quadrant actuator only for this model because the intent of this product is to close the damper in the event of a driving rain or hurricane. If you require an actuator other than our default standard then simply put forth your SDR request and Greenheck will accommodate.
Q: Can you identify a "Brand X Model XYZ" louver?
A: Most often, yes we can. Competitive louver product information is available from any louver Product Specialist. We also have the capability to search the Internet for additional information.
Q: Does custom color matching cost any extra?
A: No. Greenheck will provide custom color matching at no extra charge. However, product will not be scheduled until the customer has approved the color match. Note: In-house, blendable custom color and painted louvers are available on the Quick Build program. Add 7 days to the lead-time.
Q: Does Greenheck have any models that tested 100% effective at stopping the penetration of wind driven rain?
A: Yes, louver models EVH-602 and EVH-801 have tested at 100% effective per the Building Services Research and Information Association (BSRIA) test method.
Q: Does Greenheck manufacture steel louvers in shapes other than rectangular?
A: No, only extruded aluminum stationary louvers can be made into shapes.
Q: Does Greenheck supply anchoring systems for the Miami-Dade Units?
A: Greenheck does not supply any anchors or fasteners into the building conditions, but does supply all fasteners into the product. The ESD-603D and EVH-602D series require anchors at the head and sill, the ESS-501D require anchors on all four sides and the ESD-635D and EHH-601D series have retaining angles on all four sides of the units (no anchors into building conditions required).
Q: How are the Miami-Dade Units sized in CAPS?
A: The answer to the question… depends on the unit. The ESD-603D, ESD-635D, EHH-601D series are entered as rough opening sizes, while the ESS-501D and EVH-602D series are sized nominal or actual. Greenheck will undersize the units accordingly, taking into account thermal expansion as well as our head and sill anchor plates (see submittals for undersizing rules).
Q: How fast can I get Greenheck Miami-Dade Louver?
A: All Miami-Dade louvers can now be entered as a standard product. Standard, mill finished EHH-601D, ESD-635D, EVH-602D and ESS-501D are available on a 10 Day Quick Build program. All units with dampers and the ESD-603D are extended. As always, additional accessories may alter the leadtimes.
Q: Is a louvered penthouse with drainable blades and mitered corners available?
A: Yes, but mitered corners aren't necessary. Where would the water drain? We recommend box corners on the drainable blade penthouses.
Q: Is an exterior bird screen available?
A: Yes.
Q: What are the finish warranties for Greenheck louvers?
A: When supplied on aluminum louvers, baked enamel finishes carry a 1-year warranty. Acroflur (modified Kynar) finish carries a 5 year warranty and Kynar 500 finish is warranted for 10 years. As an industry standard, finishes supplied on fabricated steel louvers do not carry any warranties.
Q: What is Greenheck's standard manufacturing procedure for assembling louvers?
A: Greenheck uses stainless steel mechanical fasteners to assemble louvers. Welded construction is available for nearly all products as an option.
Q: What is the best way to spec sizes of Greenheck louvers?
A: Always specify as width x height. The width will be the dimension that runs parallel to the blade.
Q: What is the difference between a "J" style louver blade and a "K" style?
A: "K" style blades incorporate an additional offset, or "rain hook" in each blade which is intended to provide additional protection against water penetration. The actual performance of the two styles is very similar.
Q: What is the difference between face velocity and free area velocity?
A: Face velocity is the total CFM divided by the total area square footage used. Free area velocity is the CFM divided by the square footage of the free area. (Free area velocity is the industry standard.)
Q: What is the lead-time for engineering submittal drawings?
A: Lead-time for engineered submittal drawings fluctuate depending on our backlog of engineered (non-standard) orders. Lead-times for very basic projects may be 1-2 weeks while more complex projects may be up to 6 weeks.
Q: What is the most common position for a bird and/or insect screen to be mounted?
A: On the internal (rear) side of the louver. External (face) mounting is an available option, except in Quick Build and is available in mill finish at no additional cost.
Q: What is the most common position for a flange to be mounted on a louver?
A: Around the external (face) perimeter of the louver. Internal (rear) perimeter flanges are also available. Internal flange louvers would be treated as a special design request, so additional lead time and cost is required.
Q: What is the standard flange dimension?
A: Unless specified differently, our louver mounting flanges are supplied 1-1/2" wide.
Q: What should I look for in the specifications that tell me what type of product is required?
A: Most specifications will list the "protocols" that must be abided by. You will find that in most circumstances TAS-201 (Large Missile Impact Test), TAS-202 (Uniform Static Air Pressure) and TAS-203 (Cyclic Wind Loading Test) are specified. If that's the case, quote Greenheck model ESD- 603D, ESS-501D, ESD-635D, EHH-601D or EVH-602D depending on other specifications. However, be on the lookout for TAS 100(A) (Wind-Driven Rain Test). It is not specified nearly as often as the others, but will have a great impact on your cost. If you see TAS 100(A), you can quote Greenheck model ESD-603D/HCD-240, EHH-601D/VCD-40 or EVH-602D/VCD-40.
