1 Curtain Wall Systems The Fusion Of Strength And Efficiency Advanced Composite Design U Values as low as 0.21 CRF (frame) up to PSF Water Tested/Certified 60 PSF Design Pressure Finally, a curtain wall framing system that equals the thermal performance of glass. FM Graham s GThurm curtain wall provides unsurpassed thermal resistance in an engineered composite design using continuous strand glass reinforcement to match the strength of aluminum.

2 Using our decades of combined engineering experience with aluminum curtain wall, we designed our GThurm fiberglass composite curtain wall to match aluminum s strength while far surpassing it in thermal performance. GThurm curtain wall uses the same sound principles of weathering and anchorage proven in our aluminum products. We pultrude GThurm curtain wall using our revolutionary G2RP process, featuring continuous stranded glass fiber embedded in polyurethane. G2RP exhibits extraordinarily high thermal resistance, high strength, and it s highly resistant to condensation. Our GThurm curtain wall was designed to equal the structural performance of our aluminum products. G2RP has 700 times less thermal conductivity than aluminum GThurm framing is essentially all thermal break. Aluminum framing must compromise the structure by incorporating supplemental thermal breaks to separate warm and cold surfaces. GThurm curtain wall is nearly immune from typical aluminum system problems like thermal short circuits and thermal expansion in the warm side of systems. GThurm is 700 times less conductive than aluminum, virtually eliminating the cold spots that can lead to damaging condensation problems. Thermal Performance Modeling GThurm Modulus of elasticity 8000 KPSI Stress KPSI 6061 T6 Aluminum Modulus of elasticity 10,000 KPSI Aluminum deforms at 40 KPSI Conventional aluminum curtain wall Strain - in/in GThurm 6061 T6 aluminum Modulus of elasticity comparisons of GThurm and aluminum show that while the initial strength of aluminum is greater, GThurm continues to exhibit high strength long after aluminum deflects. G2RP is an advanced fiberglass composite consisting of 80% continuous glass fiber thermally set with 20% Bayer Baydur polyurethane resin. G2RP exhibits a flexural strength of nearly 300% higher than typical polyester and vinyl ester fiberglass. The G2RP framing components virtually eliminate the thermal conductivity issues experienced with aluminum framing. Our 80% glass G2RP framing creates a homogenous relationship with the glass it encases. Actual Therm 6.3 thermal modeling results showing a comparison between conventional aluminum and GThurm.
