In the building products industry, surface durability is just as critical as structural integrity. CTI combines the sustainability and machinability of Falcata with our proprietary Vindex™ finish to create a high-performance material that meets the demands of modern millwork—without the weight or resource intensity of traditional hardwoods. This engineered pairing delivers a protective finish for lightweight wood, enhancing durability, improving finish consistency, and reducing waste.


By using Vindex™-finished Falcata, clients benefit from:

  • Lower installed costs due to reduced damage and rework

  • Cleaner profiles with less chipping during machining and installation

  • Smoother paint and finish applications


From trim and casings to profiles and beyond, this combination bridges the gap between environmental responsibility and dependable performance across the millwork industry.



Why Falcata? Lightweight, Sustainable, and Efficient

Falcata is a fast-growing, lightweight substrate that offers an ideal balance of workability, low density, and sustainability. On average, Falcata weighs 17–20 lbs per cubic foot, compared to pine, which averages 28–35 lbs per cubic foot, depending on the species.


That reduction in weight translates into:

  • Easier handling during manufacturing

  • Lower shipping costs for bulk orders

  • Faster milling with less tool wear


Falcata matures in a fraction of the time required by traditional species, making it a smart choice for clients seeking scalable, renewable materials. However, due to its low density, it benefits from a protective finish for lightweight wood that improves surface strength and long-term durability. That’s where Vindex™ comes in.

What Is Vindex™? A Finish Engineered for Performance

Vindex™ is CTI’s proprietary finish, developed to address the performance gap between lightweight substrates and heavier hardwood alternatives. Applied in multiple stages—including sealing, sanding, and optional spray coatings for interior or exterior standards—Vindex™ provides a consistent, high-strength layer that protects Falcata from environmental and handling-related wear.


Key benefits include:

  • Scratch resistance to withstand transport and installation

  • Water resistance to reduce swelling and delamination

  • Consistent finish thinness  for clean machining

  • Paint and sealant adhesion for easier finishing in the field

  • Elasticity that prevents cracking at fastener points or edges


By applying a protective finish for lightweight wood like Falcata, we expand its use into more demanding applications while preserving its weight-saving advantages.



Lab-Tested Strength

Our in-house material lab ensures that Vindex™-coated components meet strict performance standards.


Falcata products finished with Vindex™ are subjected to many tests, with a few being:

  • Boil tests for water resistance

  • Scratch and abrasion testing

  • Blunt impact testing


These quality control processes ensure that every board, profile, or small part performs consistently across residential, multi-family, or commercial builds.



Better Results Start with Better Finishes

At CTI, we believe high-performance materials shouldn’t come with trade-offs. By pairing Falcata with our engineered Vindex™ finish, we deliver lightweight wood products that offer the strength and reliability you need—without the weight or waste you don’t.
