Wheaton & Sprague Engineering provides Thermal Analysis & Design of exterior cladding systems, utilizing THERM 5.2 and WINDOWS 5.2 finite element analysis programs to glazing contractors who are being required to include thermal analysis in their submittal packages to comply with contract documents prepared by the architect.WSE will now be able to provide that submittal package for you. Additionally, WSE can now assist our clients in evaluating a new design for thermal efficiencies before that design is finalized. WSE can offer system design and thermal analysis as a comprehensive package or can provide them as standalone services.

Using THERM, WSE can model two-dimensional heat-transfer effects in building components such as windows, walls, foundations, roofs, and doors; as well as other products where thermal bridges are of concern. THERM's heat-transfer analysis allows WSE to evaluate a product’s energy efficiency and local temperature patterns, which may relate directly to problems with condensation, moisture damage, and structural integrity.

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.
