Making Sound Decisions

by admin on March 10, 2011

Selecting and installing sound control doors can be a daunting task, to say the least.  Whether your project calls for a sound door consisting of a straight-forward model and size, or a custom-designed door where aesthetics is as important as performance, there are key factors to consider in making your final decision.

By purchasing from Stiles, you’re dealing directly with an experienced built-to-order manufacturer company that has the technical expertise and after-sale service that’s critical when it comes to sound control products. Here’s a few pointers to help you in your selection of sound control doors:

The Basics

Sound control doors, also called “acoustical” or “acoustic” doors, are built to laboratory test standards and rated in accordance with very specific STC (sound transmission class) levels.  The higher the STC level, the more sound blocking capabilities the door offers.  However, the door itself is only one component of a complete assembly that includes the frame, seals, glass, threshold, hinges, locksets and other hardware.

Off-the-shelf sound control doors are normally shipped KD (knocked-down) and require time-consuming on-site labor.  The risk of lost parts and improper assembly can spell disaster in terms of time, proper performance and added expense.

Solution: Stiles factory-assembled sound control door packages arrive at your jobsite ready to install into the opening.  With 40 years experience in manufacturing sound control doors and windows, you can rest assured that your products will arrive with all components — including seals, hardware, and even glass — professionally installed and packaged.



Because sound control doors require specialty perimeter seals, the clearances between seals and locksets may create “pinch points” or, in some cases, not be feasible at all because of inadequate clearances.  Other concerns, such as utilizing cam-lift hinges in conjunction with certain door closers, must be addressed long before you take shipment.

On site finishing of doors and frames requires careful coordination between trades.  All too often, doors and frames are improperly field finished because of neglect, rushed schedules, and improper masking / finishing.

Solution: Stiles sound control doors are available factory-finished in a variety of abraded metal finishes, standard and custom finish paint colors, wood stains, and clear protective coatings.  Our finishes are eco-friendly, and all finishing takes place in a controlled environment. Components are finished prior to factory-assembly to ensure crisp, clean lineage and complete finish coverage.
