This Statement of Work (SOW) details Portsmouth Naval Shipyard's procurement of insulated flexible ductwork for temporary HVAC systems. The specification requires 20 IN nominal inside diameter ductwork in 25 FT long sections, designed to withstand harsh outdoor environmental conditions. Key technical requirements include a minimum R-value of R-8, construction using high-strength sewn two single-ply polyurethane coated polyester fabric with a proprietary insulation barrier, fire-resistant performance rating, and a working pressure of ≥ 25 IN/W.G.

Critical performance specifications mandate that both inner and outer duct layers be flame retardant (V-0 rating), feature excellent UV stabilization, mold and mildew inhibitors, and operate in temperature ranges from -60°F to +400°F. The ductwork must be fully-flexible with a 1-foot bend radius and fully-compressible, transported and stored in pallet-sized wire baskets. The approved model referenced is Flexaust FX-400 IF, and vendors must provide comprehensive documentation including brochures, specifications, assembly sketches, and compliance statements when responding to this procurement request.
