Inteplast Building Products uses both the Celuka and Freefoam extrusion processes to make their suite of interior and exterior trim products. Both process extrude the trim through dies, but it’s the cooling process that produces the different product densities.
Inteplast Building Products uses the Celuka extruding process which quickly cools the outer surface of trim board, while expanding the inside of the product, forming a solid, hard skin, which is the toughest surface in the industry.
The hard coating on our Celuka trim protects the product from dents and scratches, not only once it’s in place on the project, but also during transit to the job site, which means fewer damages and less product returns.
Trim profiles are extruded through the Freefoam cooling process where the cell structure is formed over the entire cross-section of the profile. The growth of cells at the surface are repressed through the cooling of the extruded melt to create a flat, rigid, but lightweight, closed-cell trim sheet.
Our Inteplast Building Products Trim FreeFoam is ideal for window surrounds and applications where uniform thickness is needed, such as corner boards, beadboard, soffits, fascia, column wraps, and window and door trim.
