OCTOBER, 2014  REYNOBOND PE COLORWELD 500 5 EC 97909-055074213 FORMED METAL WALL PANELSGuide Specs

The above tests are on panel systems that do not include a waterproof membrane behind panels.

2.3

Accessories

A.

Extrusions, formed members, sheet and plate shall conform with ASTM B209 and the recommendations of the manufacturer.

B.

Panel stiffeners, if required, shall be structurally fastened or restrained at the ends and shall be secured to the rear face of the composite panel with silicone of sufficient size and strength to maintain panel flatness. Stiffener material and/or finish shall be compatible with the silicone.

C.

Sealants and gaskets within the panel system shall be as per manufacturer's standards to meet performance requirements.

D.

Fabricate flashing materials from 0.040" minimum thickness aluminum sheet provided by panel manufacturer to match the adjacent curtain wall/panel system where exposed. Post-painted spray-applied flashings are not acceptable. Provide a lap strap under the flashing at abutted conditions and seal lapped surfaces with a full bead of non-hardening sealant.

E.

Fasteners (concealed/non-corrosive): Fasteners as recommended by system fabricator and installer.

PART 3 -

Execution

3.1

Inspection

A.

Surfaces to receive panels shall be even, smooth, sound, clean, dry and free from defects detrimental to work. Notify contractor in writing of conditions detrimental to proper and timely completion of the work. Do not proceed with erection until unsatisfactory conditions have been corrected.

B.

Surfaces to receive panels shall be structurally sound as determined by a registered engineer.

3.2

Installation

A.

Erect panels plumb and level.

B.

Attachment system shall allow for the free vertical and horizontal thermal movement due to expansion and contraction for a material temperature range of -20ºF (-29ºC) to +180ºF (+82ºC). Buckling of panels, opening of joints, undue stress on fasteners, failure of sealants or any other detrimental effects due to thermal movement are not permitted. Fabrication, assembly and erection procedure shall account for the ambient temperature at the time of the respective operation.

C.

Panels shall be erected in accordance with an approved set of shop drawings.

D.

Anchor panels securely per engineering recommendations and in accordance with approved shop drawings to allow for necessary thermal movement and structural support.

E.

Conform to panel fabricator's instructions for installation of concealed fasteners.

F.

Do not install component parts that are observed to be defective, including warped, bowed, dented, scraped and broken members.

G.

Do not cut, trim, weld or scrape component parts during erection in a manner that would damage the finish, decrease strength or result in a visual imperfection or a failure in performance. Return component parts that require alteration to shop for refabrication, or for replacement with new parts.

H.

Separate dissimilar metals; use appropriate gaskets and fasteners to minimize corrosive or electrolytic action between metals.

3.03  Adjusting and Cleaning

A.

Remove and replace panels damaged beyond repair as a direct result of panel installation. After installation, panel repair and replacement shall become the responsibility of the general contractor.

I.

Repair panels with minor damage.

J.

Remove masking film (if used) as soon as possible after installation. Masking intentionally left in place after panel installation on an elevation shall become the responsibility of the general contractor.

K.

Any additional protection, after installation, shall be the responsibility of the general contractor to remove.

L.

Make sure weep holes and drainage channels are unobstructed and free of dirt and sealants.

M.

Final cleaning shall not be part of the work of this section.
