Patented technology minimizes shrinkage
in dark windows and doors

While the growing demand for contemporary designs has made dark-framed windows and doors top sellers, the unsightly results of thermal movement also put them at the top of a less-desirable list—reasons for warranty claims. Until now.

Multi-Core Extrusion (mcX) is our patented polymer-based solution for UV exposed parts that makes dark windows and doors just as attractive to manufacturers as they are to consumers. mcX has minimal shrink, it installs smoothly, and works with your existing manufacturing platform.

The Benefits of mcX

Our minimal-shrink, polymer-based solutions for UV exposed parts enhance their performance, especially in dark colors.

• UV protection
• Thermal stability
• Superior impact
• Better surface finish
• Lower cost
• No aluminum = no kinking, denting, or inconsistent weathering
• Zero manufacturing transition
• Endlessly customizable

A Polymer Part with Minimal Shrink

Our mcX technology sandwiches heat-resistant polymers inside standard polymers. We take advantage of the combined materials' positive attributes to produce a heat-resistant part without sacrificing impact or appearance consistent with the balance of the system.

With our patented technology, we can customize the percentage of heat-resistant material in individual parts, fine-tuning the mix to meet the thermal and insulation performance, budget, and appearance that your project requires.
