TU24000 Dual Pocket Poured & Debridged Thermal Storefront

Providing superior thermal performance that meets or exceeds today’s stringent energy codes.

Tubelite 300ES Curtainwall Series framing is designed for superior thermal performance. The 300ES uses Therml=Block thermal strut technology, featuring System U-Factor as low as 0.31 and Condensation Resistance Factor (CRF) up to 81 using 1″ insulating glass.

The exterior face has a 2-1/4″ sight line and available in 6″ and 8″ depths. Ideal for curtainwall applications up to four stories and the inside glazing feature offers reduced field installation time and expense.

Separate interior and exterior frame members allow different finishes on each.

A break from high energy costs!
