With FormLok® dovetail floor deck, you can hear the difference. That difference is silence. When used with a typical assembly, our dovetail deck system gives you the design freedom to finish your floor any way you see fit. Thanks to its superior sound ratings, you can choose from a variety of floor assemblies and finishes that fit your vision, meet code, and boast sound transmission ratings (STC) and sound impact ratings (IIC) 
over 50. Get a modern industrial look with exposed concrete. Choose engineered wood flooring for a more classic feel  
or select from a multitude of other materials to create  something totally unique.

A roof deck that stands out in a crowd.

Dovetail roof deck and acoustical roof deck combine functional, structural, and aesthetic design. The innovative profile boasts a clean, sleek design with distinct shadow  lines to provide texture to the ceiling’s surface and naturally  hide unsightly roof system fasteners with dovetail deck.  The acoustical roof deck is particularly suitable in structures when sound control is a key design element.

Silence the crowd  with superior acoustical performance.

Along with its aesthetic design, dovetail acoustic  roof deck uses proven sound reducing technology  to help lower levels of ambient background noise.  Its excellent acoustical performance with a  
Noise Reduction Coefficient (NRC) of 0.95 to 1.15  can achieve greater clarity of original sound and  deliver a calm, quieter interior environment especially in structures such as auditoriums, natatoriums,  schools, gymnasiums and theaters. 

Dovetail deck finishes have you covered.

Options ranging from bare galvanized to high-performance paint systems for demanding environments give you freedom. Freedom to use your imagination. Freedom to choose the right solution for every project situation.
