Fasteners & Sealants

Big ImageWhether you are fabricating an awning in your shop, installing a patio cover in the field, or building one of our custom built NatureScape® Patio Rooms, the importance of having the proper fasteners and sealants is many times overlooked.  That is why at Crest Aluminum we make it a priority to maintain an extensive inventory of high quality zinc plated & stainless steel fasteners, as well as a variety of DOW Corning® and OSI Sealants.  Our fasteners are available in different sizes and styles with some of them available in several different colors, painted to match the materials you are working with.  If you don't see what you are looking for, call us and we will find it for you!

Quality fasteners, Quality Sealants, Quality Workmanship

Dow Corning CWS
Dow Corning® Contractors Weatherproofing Sealant is a medium modulus 100% silicone joint sealant.  This unique, weather-resistant formulation is ideal to withstand adverse conditions, including moisture, movement, sheer and deflection, in common installations.  Featuring excellent all-weather gunnability and performance, CWS is steadily becoming the sealant of choice for many of our customers. 

OSI Sealants
SBR-100 Window & Siding Sealant is a popular choice among contractors and remodelers offering year round use and consistent extruding with no tooling required.  OSI SBR-100 is paintable when fully cured, water resistant and durable.  This sealant is a great choice when working with windows, doors, siding, and awning applications where minmimal joint movement is expected.

Peel & Seal™ PoweBond 250
Peel & Seal® PowerBond™ White 250 is thinner and more aggressive than normal Peel & Seal®, making it easier to install. It is specifically designed to tape seams on insulated aluminum panels or can be used as a flashing material for roof and gutter repair, window flashing and as a general-purpose waterproofing product.
