Stc Glass Doors

When specifying acoustical doors one often overlooked concern is the hardware.

Stc glass doors.

Glass by itself is a weak noise insulator but methods such as lamination or double glazing can improve performance significantly. The stc ratings allow accurate apple to apple comparisons. Laminated glass laminated glass is also available for added strength enhanced security and sound control. A higher stc rating translates into more reduction in sound.

Sound transmission class stc ratings for glass vary from poor to practically soundproof. Stc ratings are used for windows doors walls and most building materials. Soundproof steel doors are available with acoustic glazing that is factory pre installed. Additionally cam lift hinges and an aluminum threshold are included with high stc rated assemblies.

Stc is expressed in decibels db and is used to measure a building material s ability to reduce sound. For windows stc ratings range from 18 to 38. Assemblies have been designed to accept readily available heavy weight builders hardware. Krieger acoustical doors are delivered as complete performance guaranteed acoustical assemblies with seals hinges and threshold included.

Safety glass tempered safety glass is available on all products and comes standard on all patio doors. Soundproof doors are available at greater thicknesses from stc 54 to stc 64. Standard monolithic or single pane glass is the cheapest option and works well for most interior applications. Wood doors up to stc 49.

Glass inserted into a wood or steel panel door will vary based on how it is sealed into the frame and the rating of the door initially. Milgard quiet line windows can achieve an stc rating of up to 48 for exceptional sound control. Standard glass doors can have an stc between 28 and 35 laminated between 35 and 40 and soundproof glass from 48 to 55 or higher. Because acoustical doors are constructed differently than traditional hollow metal doors certain considerations must be made when selecting hardware for them.

Stc rated doors should always be installed by a professional. The typical rating for single pane windows is 18 20 while a double glazed window is 28 32. An stc rating is an instrument measurement of how much noise is stopped. Fixed windows up to stc 55.

Soundproof steel doors are available 1 3 4 thick from stc 33 to stc 53. The higher the rating the better the sound control. Sound reducing glass this glass helps reduce the volume of outside noise. Available with low e smartsun and heatlock coatings.

Metal doors up to stc 57. On site installation can be pretty easy if the door has been assembled prior to delivery by the factory. There are quite a few complicated steps in the installation process that are critical to the performance of the door. Stc ratings are the only way to accurately compare various noise reduction products.
