INSULBAR® is a revolutionary insulating system for manufacturers of aluminum windows, doors and curtain walls. Proven in over 20 years of worldwide installation, Insulbar® Structural Thermal Barriers offer superior strength, maximum resistance to heat transfer and unexcelled flexibility.

Economical and Efficient - up to 50% better thermal insulation than PVC or Polyurethane!

The key to Insulbar's effectiveness is its unique composition of glass-reinforced nylon 6/6. Ensinger's proprietary extrusion process orients the glass fibers in three directions, countering stress in these dimensions for maximum structural integrity.

An Insulbar system provides superior insulation through increased aluminum separation and air space. The material is extruded into a shape that effectively and economically joins two separate aluminum extrusions (the inner and outer aluminum profiles of the window, door or curtain wall).

Insulbar® includes a sealing wire that, under elevated temperature, activates to create a strong, permanent bond that seals out moisture and improves shear resistance.

Since Insulbar's coefficient of thermal expansion is very close to that of aluminum, internal stresses are drastically reduced. The bond between Insulbar® and the aluminum extrusion retains its mechanical integrity through a wide range of temperature fluctuations.

The strength of the composite profile is increased due to Insulbar's composition and system geometry.

ALLOWS THINNER ALUMINUM WALLS!

Insulbar is a system with inherent strength, permitting the use of thinner aluminum walls even with similar hollow section construction. Manufacturers save on material costs and can offer reduced weight in finished assemblies.

Insulbar® is the strongest structural thermal barrier available, delivering a better combination of insulation and strength than PVC or poured and debridged polyurethane!
