Wheaton Sprague provides Thermal Analysis & Design of exterior cladding systems, utilizing THERM 5.2 and WINDOWS 5.2 finite element analysis programs.
THERM uses two-dimensional (2D) conduction and radiation heat-transfer analysis based on the finite-element method, which can model the complicated geometries of fenestration products and other building elements. Fenestration products are those that fill openings in a building’s exterior cladding such as windows, doors, skylights, curtain walls, etc., designed to permit the passage of air, light, vehicles, or people.
WINDOWS 5.2 and OPTICS 5.1 are companion programs that are used in conjunction with THERM 5.2 to create and evaluate framing systems and glazing components.
