Manufactured in Spokane, WA Since 1970
The Steelhead series was developed to meet the increasingly demanding energy efficiency regulations. With a frame depth of 3 1/4", it features an Insulbar LEF polyamide strut in lieu of a rigid thermal break which results in superior thermal performance and also allows for a dual-color window.
In addition to the Insulbar strut, the Steelhead window features an interior foamed insulation zone.
These features substantially reduces thermal transfer from the exterior of the window to the interior. Along with warm edge spacer, these integrated features reduce heating and cooling loads on HVAC systems, providing long term energy efficienty and utility savings.

Insulbar LEF Strut Technology
The Steelhead features innovative Insulbar LEF polyamide strut thermal barrier technology that thermally breaks conductiviety of the aluminum frame. The polyamide strut has an ultra-thin applied Low-E film. The film is applied at right angles to the thermal conduction direction on the thermal insulating bar flag, minimizes losses due to thermal radiation at windows, doors and facades, and has the same effect as insulating foam.
Insulbar insulating struts are extremely efficient at preventing energy losses in buildings and enable outstanding Uf values up to conformance with the stringent passive house standard. Lower energy consumption, reduced heating bills and a greener planet - these are the effects achieved through the use of Insulbar.
Foam Filled Insulation Zone
The Steelhead window has an interior foamed insulation zone. Foam filled windows provide superior thermal performance (measured by U factor and condensation resistance), as well as a little bit of extra structural stability. It can also improve sound transmittance as well.
Finishes
The Steelhead series features 2 separate Class I aluminum profiles joined by a polyamide strut allowing for dual finish applications.
Marlin offers anodized, painted and powder coat finishes in any available specification or color. The strut profile and film are heat resistant up to 392 °F (for up to 20 minutes), so we are able to powder coat the complete assembly. Custom colored windows require extended lead times for color selection, sample submittal, and production as well as additional cost for setup and minimum order quantities, so Marlin recommends this as an option for larger projects that allow for added time.
Marlin inventories the two most popular anodized finishes - dark bronze and clear anodized for all of our window series. See below for sample colors of our clear anodized, dark bronze anodized and black anodized options.
