TESTIMONIALMore
“Prior to using pre-kerfed substrates provided by Interior Products Inc., we painstakingly saw-kerfed plywood panels manually for use in radius millwork applications. Interior Products flexible substrates have cut our skilled labor costs dramatically. The variety of materials supplied by Interior Products (Kerfkore, Timberflex, Flexboard and Ultralite) lends itself to numerous applications and options: panels, doors, curtain walls, mouldings and traditional curved millwork. We can use Interior Products in applications where the weight of plywood panels would be impractical.

Using Kerfkore we can create inlays in flat panels, then bend the panel. Applying inlays to already curved surfaces is tedious, if not impossible. Designers and architects have been delighted with the creative flexibility we can offer them.

During the construction of millwork at Nationwide Arena, Columbus (Ohio) new NHL hockey arena, the designers came to us with a fabrication problem. The original design for a concession area included a steel channel in an elliptical shape suspended from the arena's ceiling. When the structural engineers reviewed the plans, they objected to the fixtures the weight was too great to be properly supported. The design team asked us to find a solution. We used Timberflex to create a curved ceiling fixture painted to mimic the steel channel. Even the steel fabricators were fooled, and the fixture was incredibly light. Interior Products gives us options that we never had before.”
