<br />CITY OF SOUTH BEND <br />STUDEBAKER NATIONAL MUSEUM <br />SKYLIGHT REPLACEMENT TRANSLUCENT SKYLIGHTS 08952-1 <br />SECTION 08952 - TRANSLUCENT SKYLIGHTS <br /> <br />A. Scope <br /> <br />This section covers furnishing all labor, materials, and equipment necessary for complete installation <br />of translucent panels within an existing skylight frame system, as indicated. <br /> <br />1. Related Documents: The provisions of the General Conditions, Supplementary Conditions, and <br />the Sections included under Division 1, General Requirements, are included as a part of this <br />Section as though bound herein. <br /> <br />2. Performance Requirements: <br /> <br />a. General: Provide assemblies capable of withstanding loads and thermal and structural <br />movements indicated without failure. Failure includes the following: <br />1) Sandwich-panel deflection exceeding manufacturer’s recommended limits or <br />causing panel failure. <br />2) Thermal stresses transferred to the building structure. <br />3) Noise or vibration created by thermal and structural movement and wind. <br />4) Loosening or weakening of fasteners, attachments, and other components. <br /> <br />b. Thermal Movement: Provide systems that allow for thermal movement resulting from the <br />following maxi um change (range) in ambient and surface temperatures by preventing <br />buckling, sealant failure, and other detrimental effects. <br />1) Temperature Change (Range): 120 deg. F, ambient; 180 deg. F, material surfaces. <br /> <br />c. Air Infiltration: Provide skylights with maximum air leakage of 0.05 cfm/sq.ft. of surface <br />when tested according to ASTM E283 at a minimum static-air-pressure differential of <br />6.24 PSF. <br /> <br />d. Water Penetration: Provide skylights that do not evidence water penetration when tested <br />according to ASTM E 331 at 15 psf and to AAMA 501.1 Dynamic Water Test at 15 psf. <br /> <br />3. Submittals: <br /> <br />a. Product data for each type specified, including details of construction relative to <br />materials, dimensions of individual components, profiles, finishes, and glazing light <br />transmission and thermal characteristics. <br /> <br />b. Shop drawings showing sizes, materials, and details of construction. Include shop <br />drawing submittals certified load bearing data. <br />1) Submit complete signed and stamped data by a licensed Engineer certifying that <br />provided assemblies of members and connections will adequately support <br />required loadings. <br /> <br />c. Submit test reports from accredited laboratories verifying required performance <br />characteristics. <br />1) Test reports required include: <br />a) Flame Spread and Smoke Development (ASTM E84) <br />b) Burn Extent (ASTM D635) <br />c) Insulated “U” Factor (NFRC 100) <br />d) Impact Strength (UL 972) <br />e) Class A Covering Burning Brand (ASTM E108) <br />f) Color Difference (ASTM D2244) <br />g) Beam Bending Strength (ASTM E 72)
