San Francisco presents a highly complex environment for commercial construction and industrial piping infrastructure. The dramatic microclimate variations—spanning the damp, salty marine layer fog of the Sunset District to the warmer, drier inland microclimates—make insulation selection a make-or-break technical decision.
Furthermore, California's strict Title 24 Energy Efficiency Standards demand thermal insulation with extremely low thermal conductivity to minimize energy waste. Closed-cell rubber foam insulation stands out as the ultimate material of choice, addressing the key local priorities:
A closer look at the physical properties that set our elastomeric foam sheet rolls apart in thermal performance and long-term energy savings.
Our proprietary foaming process blends NBR and PVC to construct a uniformly distributed micro-cell matrix. With a closed-cell rate exceeding 98%, it effectively seals out moisture-laden air, ensuring that moisture does not accumulate inside the material, preserving its insulating properties.
Maintains an extremely low thermal conductivity ($\lambda \le 0.034$ W/m·K at 0°C). By trapping dead air within the micro-cells, heat transfer is severely restricted. This ensures massive energy efficiency gains across chilled water systems and hot-water supply lines alike.
Safety is a primary design factor. Our compound meets BS 476 Part 6 & Part 7 standards. It is self-extinguishing when exposed to open flame, does not generate toxic drippings, and minimizes smoke development, complying with local municipal building safety codes.

Beyond traditional thermal insulation, our elastomeric foam sheet rolls serve as excellent sound barriers and mechanical vibration dampers.
Modern building designs, such as high-density developments in San Francisco, require high-performance acoustic isolation between floor plates, mechanical rooms, and HVAC ducts. Because air conditioning units and chiller lines produce continuous noise, raw sheet rolls are installed directly to the exterior or interior of metal ducts to reduce transmission noise.
Our elastomeric compound features a flexible structure that absorbs low-frequency vibrations, preventing noise from radiating through building structures. This is highly effective in multifamily residential buildings, luxury hotels, and hospitals, where indoor comfort is critical.
For demanding applications—including liquid nitrogen storage, chemical cooling lines, and marine cold chain shipping—Kingflex cryogenic elastomeric foam provides excellent thermal and mechanical stability.
Standard insulation materials can become brittle and crack when exposed to extreme sub-zero temperatures. Our specialized cryogenic rubber foam is formulated to remain flexible at temperatures as low as -40°C (and down to cryogenic ranges when paired with multi-layer vapor barrier systems).
This flexibility prevents thermal stress cracking due to rapid contraction during system startup, ensuring a continuous vapor seal and maintaining long-term insulating performance.
