Why Our Return Air Grille is Made with High-Quality Urethane Resin
Here at Beaux-Arts Classic Products, we proudly craft extraordinary decorative return air grille and vent cover products. Our interior supply and return grilles, to exterior grade foundation grilles, they are all cast in the USA, from pure Urethane resin.
What is urethane resin, and why do so many manufacturers choose this material? In this article, we break down the key benefits of urethane resin and the reasons why this option outshines alternatives.
Urethane Resin for a Lifetime Return Air Grille
The reason we use plastic is because it gives us the end results we are looking for. The two-part Urethane we use gives us a perfect smooth casting every time, no grain, no air bubbles, no flash. Plus it is the greatest outdoor material, since it will not rust, rot, corrode or grow mold. It is also impervious to water and UV rays. It is also strong, but not brittle.
Urethane resin is a two-part casting resin like epoxy, but more liquid. A great casing material. It is impervious to water, won’t rust, rot or corrode. It is strong and durable.
Due to its liquid natural state, during the molding process, we are able to precisely reproduce the classic looks that ensure your spaces maintain their aesthetic beauty white showcasing your unique style.
Our Urethane Resin Is Tempered For Strength
We not only cast the molds, but we designed and milled the part necessary to make the first mold. So when we get an order, we pull out the correct size and style mold, mix the resin and pour it into a mold. In about four hours the new casting can be extracted from the mold. Then it is placed in an industrial oven to temper at 300 degrees for 8 hours. At Beaux-Arts, we make our products stronger by “tempering” the resin, which improves all aspects of strength and endurance.
Once the castings are removed from the ovens, they are also heat resistant to 200 degrees and can be used on radiator cabinets. Also a number of small tasks take place. The back is sanded and painted, the screw holes are drilled on a drill press.
Urethane resin is the right product for HVAC grilles because moisture is a byproduct of air conditioning, which causes rust and mold growth. Plus our resin castings do not vibrate, so our grilles don’t make the irritating high pitched sounds that the white louvered return grilles do.
Why Don’t We Make Our Return Air Grille from Cast Iron or Aluminum?
Given the fact that we make functional works of art, the Urethane Resin is the perfect material, much better than cast Iron or Aluminum. First of all, iron is a terrible casting material that is normally cast in temporary molds made from pressed sand. The finished product has a very grainy surface, air bubbles, plus lots of flash where the two parts of the same mold fit together. Most cast iron sand casting require lots of additional machining and finishing to remove the grain and flash.
Superior casting metals such as bronze and brass are normally cast in the lost wax method, which is so expensive these days it is now called investment casting. The lost wax method starts with a wax model or “plug” which is dipped repeatedly into a vat of plaster until thoroughly coated. Then it is heated until all the wax flows out of the one piece plaster mold, a hammer is used to break away all the plaster. So each plaster mold makes only one casting, which is why it is so expensive. The castings also require lots of finishing and buffing before they can be sld. No wonder it is called investment casting, which is now almost exclusively used for bronze statues.
Finally, you’ll never have to contend with mold, corrosion or rust with our beautiful return air grille products. The urethane resin is resistant to each of those concerns, which is why it’s a great option for your outdoor vents as well, such as foundation vents and crawl space vents covers.
