A customer in the construction industry needed manufactured fiberglass reinforcement to structurally strengthen their vinyl windows.

This was necessary in order to meet stringent standards of various cities. Tencom Limited took on this project, performing all work at our modern facility utilizing our proprietary pultrusion process and equipment.


Tight tolerance of ±0.005" was held throughout the fabrication process.


The finished product was 5" to 15' in length, with a thickness range of 0.060" to 0.250". This material can withstand temperatures from -50°F to 300°F. Fiberglass is quickly gaining popularity in construction due to its high strength to weight ratio and low thermal conductivity.

Tencom will work with customers to design structural replacements in an economical manner, maintaining or improving upon the strength and stability of original parts.

The turnaround time for a project of this type is typically 6 - 8 weeks for tooling, and 3 - 4 weeks for production.
