Purchasing a new air vent cover or register cover? Measuring is very important!

Perplexed at how to measure your existing air vent covers? 


It's easy!  There's just three simple steps for sizing your grill, register cover or air vent cover!


1.  Always remember the size of the grill is the same size as the opening in the wall, ceiling or floor.  The size is not the outside dimension of a grill cover. 


2.  Measure the length of the opening first.  ("A" in the diagram below).


3.  The height would be the vertical top to bottom measurement.  ("B" in the diagram below).

4.  Most register manufacturers size their grills in two-inch increments.  For example:  Length ("A" in the diagram above) might be found in typical sizes ranging from 10", 12" or 14".
Height ("B" in the diagram above) might be 4", 6" or 8". Your grill size might be a little smaller or the wall opening size might be a little larger.  This is normal; it creates a loose fit in the wall for the grill.  The loose fit allows room to properly level the grill.

DIY Home Projects - Why choose Classic Grills Resin for Air Vents, Grills or Registers?

What is the advantage of using Classic Grill's proprietary thermal resin for grills? 


Thermal resins that Classic Grills uses today were developed by NASA for use in the space industry.  These resins used by Classic Grills are a perfect fit for the architectural design industry. 

The durability and ability to create an array of designs and sizes in Classic Grill's resin sets Classic Grills apart from what is available on the market today. 


Classic Grills worked for many years to create a formulation that would be

• Thermal. (both against high and low temperatures)
• Rigid.  Being rigid is obviously critical to have in a final grill (air vent cover, register) which will not warp.
• Moldable.  Classic Grills can form the material prior to full canalization to conform to a desired radius.
• Paintable.  Paint adhesion to the grilles is truly important, especially with the temperature variation that grilles, air vents or registers are subjected to.
• Nail-able.  Classic Grills in resin have similar characteristics to wood when it is pin-nailed or screwed.
• Dimensionally Stable.  It is important that the resin does not expand nor contract with temperature variations experienced with a system as this can cause warping or a failure of adhesion to the resin surface.
• Moisture Resistant.  Classic Grill's goal is to allow our customers to use Distinguished Design Grilles for both interior and exterior applications.
