The gasket are made of EPDM. All hardware material are executed as non-corrosive material or aluminum so that all unit will need either maintenance nor services.
Architectural aluminum products are actually “finished” building products and like lighting fixtures or bathroom fixture.s., should be treated accordingly. All trades should exercise care during the handling and installation of all aluminum building products.
Aluminium may be protected in numerous ways. For details, refer to “Dissimilar Materials” under “Erection ” herein and to “Care of Aluminium” .
SGAPCO shows the best method of installing and anchoring its products to the surrounding construction , therefore, we provide shopdrawings for installation details.
It is essential to cover and allow for proper workmanship and installation. Minimum requirements are that the work shall be erected plumbs, level , straight , and true, accurately fitted with tight joints and intersections and adequately reinforced and anchored in place .
Architectural aluminium alloys have a coefficient of thermal expansion due to change in temperature, therefore, the products must be anchored so that they will not be distorted nor the fasteners overstressed, from the expansion and contraction of the metal.
Recognition and application of the following fundamentals for anchorage will help assure proper installation.
a)To avoid weakening of aluminium framing members, through galvanic-corrosion attack and staining of exposed aluminum surfaces, anchoring devices must be made of aluminium, non-magnetic stainless steel or other corrosion -resistant materials compatible with aluminium steel anchors may be used provided they are adequately protected as outlined in (b) under “dissimilar materials” below:
b)Anchorage must rigidly support the product in place against applied forces such as wind loading (both positive and negative) yet permit thermal movement as may be required (Se ”ThermalMovement” above).
c)Products must be securely anchored and supported at the sill to withstand for traffic (including forces exerted by cleaning personnel).
d)Special attention should be given to the design and installation of anchors at jambs products required to support forces exerted by cleaning personnel.
a) Where aluminium surfaces come in contact with metals other than stainless steel, zinc or small areas of white bronze, keep aluminium surfaces from direct contact with incompatible metals by:
1) Painting the dissimilar metals with a prime coat of zinc, chromatic primer, or other suitable primer followed by one or two coats of aluminum metal and masonry paint , or other suitable protective coating.
2) Painting the dissimilar metal with a coating of heavy-bodied bituminous paint .
3) Applying a good quality silicone material bet ween the aluminium and the dissimilar metal.
4) Use of gasket.
b) STEEL ANCHORS and other types of unexposed clips may be galvanized or zinc plated if coated after fabrication.
c) DISSIMILAR METALS should be painted if used in location where drainage from the passes over aluminium .
d) Paint Aluminium SURFACES in contact with lime mortar ,concrete or other masonry materials wit h alkali-resistant coatings.
e) WOOD or OTHER ABSORPTIVE MATER IALS which may become repeatedly wet and which are in contact wit h aluminum should be painted with two coats of aluminum house paint and the joints sealed with a good quality silicone compound.
f) Where aluminium is in contact with treated wood , wood should be treated with pentachloropenol.
