Fenestration, Structural Glazing Sealants

Innovative Fenestration Products

Obtain strong, long lasting bonds to a variety of substrates from Pecora's complete line of silicone sealants that meet or surpass industry standards for window and door fabrication applications. These sealants are ideal for both new construction and remedial window installation applications.   

Driven by advances in the window and door industry and ever stricter building codes, Pecora is continually searching to provide solutions to the fenestration industry that offer high green strength for increased factory throughput, and are compatible with the most widely-used materials.

Silicone Narrow Joint Seam Sealer - New Pecora 1215 Seam Sealer

Now there is an alternative to the odorous acrylic sealants used for sealing narrow joints and seams.  Pecora's New 1215 Seam Sealer is a VOC compliant, 100% silicone sealant that eliminates the problems associated with traditional solvent cut acrylics.  The moisture cure silicone formula reduces noxious odors on the production line, increases productivity with a faster cure rate and meets the requiements of AAMA 803.3, Type II.   It also provides UV black light visibility for improved quality control and superior adhesion to structural thermal barriers such as 1215 Insulbar® . 1215can be applied via plews gun or cartridge.

Semi-Self Leveling Silicone Sealants

New methods for sealing around screw-heads, bolt holes, corner details and mechanical fasten ers are critical to keep pace with the  changing designs  in the window and curtainwall industry. Utilizing a controlled flow silicone sealant instead of a non-sag version reduces material usage, labor and cost on average of 40% -- with no tooling. 

Pecora’s 896-SSL and 896-TBS-SSL infiltrate into all cracks ensuring a complete seal with no waste of  material while also providing excellent adhesion without shrinkage and cracking. 

• Reduce material usage average of 40%
• Infiltrate into cracks
• No tooling

Thermal Barrier Silicone Sealants

Thermal barriers were introduced years ago in to window and sash frames to insulate against heat and cold conduction. By separating the outside metal parts from the inside with a thermal barrier or insulation, the amount of heat or cold transferred through the frames can be greatly reduced, saving on heating and cooling costs. As the thermal barrier technology advances, unique sealant solutions are needed to accommodate these new materials. In response to a new generation of thermal barriers consisting of light-weight glass-reinforced nylon, Pecora has developed 896-TBS Thermal Barrier Silicone™ and 896-TBS-SSL, the first fast-cure and self-leveling sealants on the market to adhere to this new technology.       

High Impact Silicone Sealant

Window systems are often now required to provide shock, impact and vibration resistance in many areas of the country. As an integral part of these systems, structural silicone sealants must meet the AAMA 506.00 requirements of high strength and resilience in order to withstand wind cycle loads, blast and missile impacts. Pecora’s 896-HIS meets these requirements while providing the superior adhesion needed for structural glazing applications and glazing applications for hurricane & high impact-rated windows and doors. 

Exhaustive window system testing has been conducted to verify the sealant’s exceptional adhesion and performance.    

Production Enhancement Options

To increase productivity on the manufacturing line and to lower production costs, Pecora has introduced two options that can be added to Pecora’s entire line of 896 sealants: Black Light Visibility and Beaded Spacers.     

• Black Light Visibility: Pecora’s 896 sealants can be visible under black light to reveal gaps in the sealant bead. Now potential leaks can be detected immediately improving quality control and reducing the number of field failures.   

• Beaded Spacers: Eliminate the labor intensive and costly process of adding blocks or mechanical spacers to the window bedding. Beaded spacers can be included directly in the sealant firmly holding glass in place on the production line and protecting the integrity of the thermal seal.
