6 December 18, 2017 To whom it may concern: RectorSeal s Warranty statement for firestop is contingent upon actual storage conditions and proper installation. If RectorSeal firestop products are correctly installed in accordance with our stated Manufacturers instructions and according to the UL tested systems, our products comply with UL 1479 "Fire Tests of Through-Penetration Firestops" standard requirements for Environmental Exposure Tests. This test relates to the performance of firestop products as originally installed, and compares to the performance testing after exposure to extreme temperatures and high humidity for an extended period of time. If properly stored, our products have a minimum shelf life of three years, subject to inspection with the exception of our fire rated mortar and silicone products which have a two year shelf life. The Rectorseal Corporation, manufacturer of Metacaulk Fire Stop products, has always been concerned about the long-term performance of our products. We implemented a testing program prior to the UL 1479 requirement for Fire Tests of Through-Penetration Firestops. We burned materials in our UL sanctioned fire test facility to measure the performance of RectorSeal products after extended periods of time as in accordance with current standards. Some of the tested materials exceed 15 years in age. Assuming that the substrate area surrounding the actual penetration has not been damaged, we warrant that Metacaulk products will perform satisfactorily for the sustainable life of the building. Repectfully, Terry L. Gossett Terry L. Gossett Technical Service Page 4

7 March 3, 2016 To Whom It May Concern: RectorSeal s Warranty Statement for our Smoke and Acoustical sealant is contingent upon actual storage conditions and proper installation. If properly stored, our RectorSeal Smoke and Acoustic Sealant has a minimum shelf life of two years, subject to inspection. Assuming that the substrate area surrounding the actual penetration/joint has not been damaged, we warrant that the RectorSeal Smoke and Acoustic Sealant product, when fully cured will perform satisfactorily for the sustainable life of the building. If there are any additional questions, do not hesitate to call our office at Respectfully, RECTORSEAL Terry Gossett Terry Gossett Technical Services Page 5

10 PRODUCT DATA SHEET METACAULK CAULK GRADE Spray & Caulk Firestop Sealant Description Both grades of Metacaulk 1200 are a single component, general purpose fire rated sealants for construction joints such as top of the wall, curtain wall perimeter, expansion, control, etc. and for general construction gaps and voids. Metacaulk 1200 is a water based sealant that comes in two different grades. Metacaulk 1200 mastic grade is designed for spray applications and provides a fast, economical means of installation on long joint runs. Metacaulk 1200 caulk grade is a non-sag sealant that is easy to apply from a caulk gun or troweled. It cures to an elastomeric membrane seal that is suitable where dynamic movement is expected. In the event of a fire, Metacaulk 1200 will prevent the spread of flames, smoke, hot gases and water through the joint openings. No dilution or mixing is required for use. Metacaulk 1200 can be caulked from a tube, brushed or troweled from the pail, or applied with a spray pump. Metacaulk 1200 systems are rated for up to 3 hour conditions in accordance with ASTM E1966 (UL 2079) (Tests for Fire Resistance of Building Joint Systems), test standards. Metacaulk 1200 has been cycled 500 times, in accordance with the new ASTM E1399 standard. Also tested in accordance with ASTM E814 (UL 1479) for systems up to 4 hours. Metacaulk 1200 is protected in a wet stage as well as in a dry stage against mold growth with a combination of biocides. Applications Metacaulk 1200 can be used as a general purpose fire rated sealant and smoke seal for construction joints on both vertical and horizontal surfaces. Metacaulk 1200 is also an excellent fire rated acoustical sealant and can be used in areas under constant vibration or movement.

11 Installation Data Tightly pack with the appropriate backing material as listed in the selected UL Tested System design. There should be no loose insulation, voids or gaps present. Apply the required coating thickness to completely cover backing material. Consult UL Product iq for complete instructions and system listings. For Metacaulk 1200 spray application, use recommended spray equipment. Contact Technical Service at for current recommendations. When system clean up is needed, follow manufacturer's instructions for specific equipment used. NOTE: SPRAY EQUIPMENT CAN BE DANGEROUS! USE ONLY BY PROPERLY TRAINED PERSONNEL. FOLLOW ALL SAFETY AND OPERATION INSTRUCTIONS AND PROCEDURES. Spray application of Metacaulk 1200 Spray requires airless spray equipment meeting the following specifications: Working Pressure: Min PSI (172 Bar) Delivery: Min..72 U.S. gpm (2.7 l/min.) Recommended Spray Tip Orifice: to in. (0.53 to 0.64 mm) Recommended Wetted Parts All seals and contact surfaces suitable for contact with latex emulsions. A minimum 3/8" (9.5 mm) fluid line is required, a 1/2" (13 mm) line is preferred. Consult pump manufacturer for long hose runs or lifts to higher elevations. A reversible spray tip is recommended. A 6" (152 mm) fan pattern is suggested to minimize overspray. The following airless spray equipment has demonstrated suitability for application of this product.

FBC System Compatible indicates that this product has been tested, and is monitored on an ongoing basis, to assure its chemical compatibility with FlowGuard Gold, BlazeMaster and Corzan pipe and fittings. FBC, FlowGuard Gold, BlazeMaster and Corzan are licensed trademarks of The Lubrizol Corporation. Inspection & Repair RectorSeal recommends that a firestop system inspection be conducted during installation of the material in accordance with ASTM E2174 and ASTM E2393. In the event post-installation inspection and destructive sampling is necessary, RectorSeal advises repairing the damaged firestop system by replacing any material that was removed or damaged with the same product originally installed, and ensuring the assembly matches the original firestop listing. RectorSeal advises, that due to the chemical nature of firestop products and sealants, material depth should be determined by measuring the points of adhesion at the substrate bond area as sealants may decrease in size during the curing process.

12 Storage & Handling Metacaulk 1200 should be stored in unopened container between 35 (2 C) and 120 F (49 C) to obtain a 3 year shelf life. NOTE: Do not dilute; no mixing is required. Best if protected from freezing. If freezing occurs, thaw completely before use. Keep products stored under protective cover in original containers. Limitations Metacaulk 1200 is not designed to be used in areas under continuous immersion or in areas which would be continuously wet.
