Precision Manufacturing

Our proprietary CNC process delivers ±1 mm tolerance across complex, irregular geometries — proven through three years of high‑volume OEM production.

 

Custom Solutions for Every Profile

We produce inserts for 100+ unique geometries, from simple chambers to advanced multi‑cavity profiles.

 

High‑Volume Capability

With over 15,000 parts per month per machine, our system is built for reliability and scalable growth.

 

Scalable Manufacturing

Our production system is built around proprietary CNC machines engineered in‑house. Each machine delivers consistent, tight‑tolerance output, and new units can be added quickly to increase capacity. This allows Stream Infinity to scale production without compromising accuracy or repeatability.

 

Material Flexibility

GPS, EPS, polyurethane, and steel‑reinforced hybrids — engineered for thermal, structural, or hybrid performance needs.

 

Why Precision‑Cut Insulation for Window and Door Frames Matters

High‑performance window and door systems rely on more than glazing and frame design — the internal cavities play a critical role in thermal efficiency, structural stability, and long‑term durability. Precision‑cut insulation inserts reduce heat loss, improve condensation resistance, and create a more stable, energy‑efficient building envelope. When insulation fits the cavity accurately, it eliminates voids, maintains airflow paths, and ensures consistent performance across every unit.

 

Custom‑Fit Inserts for OEM Window and Door Systems

Stream Infinity manufactures custom‑engineered insulation inserts designed specifically for OEM window and door frames. Each insert is CNC‑cut to match the exact geometry of your profile, ensuring a tight‑tolerance fit that enhances thermal performance without altering your manufacturing workflow. Whether you need GPS, EPS, polyurethane, or steel‑reinforced hybrids, our inserts are built to integrate seamlessly into vinyl, aluminum, fiberglass, and hybrid systems.

 

Benefits of Precision‑Cut Frame Insulation

Improved Thermal Performance. Accurate cavity fit reduces thermal bridging and helps maintain consistent interior temperatures, supporting higher energy‑efficiency ratings.

 

Enhanced Comfort & Condensation Control

Properly insulated frame cavities help stabilize interior surfaces, reducing cold spots and minimizing condensation risk in demanding climates.

 

Structural Support Options

For high‑load areas, our Heavy Duty line integrates galvanized steel reinforcement directly into the insulation insert, providing secure anchoring and improved rigidity.

 

Noise Reduction 

Dense GPS and polyurethane cores help reduce sound transmission through frame cavities, contributing to quieter interior environments.
