The Waldorf Astoria

August 10, 2021


Location: New York, NY

We are proud to have supplied our CAFCO 3000, CAFCO 400 & CAFCO FENDOLITE M-II to our recognized applicator, Spectrum Painting Corporation in Armonk, NY, for the Waldorf Astoria renovation. The Waldorf Astoria New York Hotel opened its doors to Park Avenue in 1931. Entertaining many people from around the world. The 1.65-million-square-foot full-block building needed renovations and closed its doors in 2017. The 90-year-old building is an official exterior landmark of New York City since 1993. A team of preservationists carefully evaluated the building, identifying thousands of historical artifacts to be preserved by the building’s developer/owner.

The rooms were stripped down to the steel allowing Spectrum Painting Corporation to apply our fireproofing materialsIsolatek’s CAFCO 3000 / ISOLATEK Type 3000, ultra-high-strength, gypsum-based wet mix Spray-Applied Fire Resistive Material (SFRM). CAFCO 400 / ISOLATEK Type 400, medium density, Wet Mix SFRM, is being pumped to meet the ratings and bond strengths needed to protect the building. CAFCO 3000 / ISOLATEK Type 3000 will provide superior fire resistive performance per unit thickness and is the most cost-efficient solution for the fireproofing of high-rise structures. CAFCO 3000 is designed to meet a minimum bond strength of 1000 psf, which is required for high rise buildings over 420 ft. CAFCO 400 is an efficient solution to achieve bond strengths in excess of 430 psf (20.6 kpa).

Isolatek International’s CAFCO FENDOLITE M-II / ISOLATEK Type M-II High-density, Wet Mix SFRM will top off the project due to its Portland cement formulation, thermal performance, proven superior durability, and ease of application. Also, tested and listed in accordance with BS476: Parts 20 & 21, ANSI/ UL 263, ASTM E119, CAN/ULC-S101.

Once complete the iconic Waldorf Astoria restoration will match its original external Art Deco structure from the 1930s. It will reopen with a 375-room luxury hotel and also 375 condominium residences.
