Linetec offers two forms of thermal improvement, pour and debridge and     thermal strut  

Pour and Debridge Service When the pour and debridge process is completed and the window is assembled there is no aluminum contact throughout. Thus, transfer of temperature is interrupted, resulting in an effective thermal barrier. Temperatures of -100°C will not transfer with pour and debridge thermal barrier in an aluminum frame-neither will hot temperatures.

• An aluminum profile is extruded with a thermal barrier channel. It is designed in such a way as to limit the mass of metal on the externally exposed surface

• A specially formulated two component liquid polyurethane is poured into this channel.

• The two components consist of a reactive resin and a polymeric isocyanate. Combined in the prescribed ratio, they react rapidly to become a very strong insulating polymer. Within a few short minutes after the mixture is fully reacted and becomes a solid, the web connecting the channel is then removed by the debridging machine. Thus effecting a thermal barrier.

Linetec also has additional pour and debridge capabilities including skip debridging and double debridging.

• Skip debridge leaves a small aluminum bridge remaining across the thermal cavity. This enhances structural integrity but does sacrifice some thermal performance. Typically one inch of aluminum bridge remains every foot along the extrusion. Other ratios  can be specified.

• Double debridging is often required to minimize extrusion costs. It is also available for double fill cavities when increased structural strength and stability is required.

If you have other needs not listed, please contact Linetec and we may likely have a solution to your pour and debridge requirements.

Thermal Strut Thermal Barrier Compared to pour and debridge, Thermal Strut is a totally different approach. Rather than a singular aluminum extrusion which is cut apart after the thermal break is inserted in the channel, Thermal Strut takes two separate lineals and joins them through the use of pre-manufactured plastic. Both the inside and outside aluminum profiles are extruded independently with a cavity that will ultimately receive the strut. After the lineals are extruded, knurling wheels ride in the cavities for the entire length of the profiles, imprinting ridges into both legs of the cavity. Thermal strut permits window suppliers to offer two-color aluminum units because the inside and outside aluminum profile surfaces are independently extruded and finished.

Thermal Strut offers strength,  resistance to heat transfer and unexcelled flexibility. The key to thermal struts effectiveness is it's unique composition of glass-reinforced nylon 6/6. The process orients the glass fibers in three directions, countering stress in these dimensions for maximum structural integrity. The material is extruded into a shape that effectively and economically joins two separate aluminum extrusions (the inner and outer profiles of the window, door, or curtainwall)
