Buy On Amazon Sale No. It's a plastic razor blade but sharp enough to remove stubborn residue. The plastic design keeps you away from getting hurt by sharp blades. A steel razor blade can easily and deeply scratch auto paint, window tint, or other surface but HELEMAN plastic razor blades can do the same jobs without scratching or gouging.
This great little tool makes your cleaning easy. These rugged plastic razor blades sticker remover scraper are excellent at scraping up decals from various surfaces. In such cases, it is likely the lock-strip gasket will require full replacement due to the existing condition of the gasket material.
This is highly dependent on the age and exposure of the materials, but the majority of projects considering reglazing have aged to the point where replacement is a prerequisite. However, there are times when this may not be necessary and a waterproofing remediation can be undertaken.
Improvements may include dual-paned insulating glazing unit IGU as infill, as well as increased spandrel insulation. The aesthetic of the facade can be altered by introducing or removing metal spandrel panels. As the technology becomes more commercially viable, there is the opportunity to reglaze with vacuum insulating glass VIG for projects where the modification of a monolithic glazed system is prohibitive and increased energy performance is desired.
Introducing a new lock-strip gasket system to an aged facade with modern low-e coated insulating glass can provide additional visible light transmittance, lower solar heat gain and improved sound transmittance OITC and STC performance.
This all translates to increased interior occupant comfort and safety, as well as energy savings. As previously mentioned, remediation of a lock-strip glazing system should include an evaluation of the current physical condition for structural performance, as well as an evaluation of air and water infiltration.
Depending on the findings of this evaluation, a remediation of the existing lock-strip gaskets could be considered to maintain the serviceability of the facade. There are several elements of a lock-strip gasket system remediation that may be considered to extend the serviceability of the existing glazing system. Generally, a remedial program will employ a strategy of mechanical stabilization and preservation of the existing gasket, as well as a means of reducing air and water infiltration.
To provide structural support of the existing system, a remediation may include installation of retaining clips at exterior horizontal and vertical lock-strip gaskets. The addition of mechanically attached retaining clips will help to ensure structural performance of the system as deteriorated gaskets may not exhibit the same performance characteristics as originally designed. This is especially important at corner zones and locations anticipated to have significant wind exposure.
The use of reinforcement clips results in an increase in the resistance of the gasket to roll off the frame. The use of one clip per side provides substantially higher load capacity and still greater capacity is obtained using two clips per side. Depending on the gasket and frame profile, several reinforcement clip options are available. The majority of applications require an exterior installation, but interior clips are used for some systems to augment exterior clips.
The project-specific reinforcement requirements for the lock-strip gasket system should be designed by a Professional Engineer with experience in facade engineering evaluations. The engineer will be able to determine the number of clips and spacing requirements as well as evaluate the profile of the clip to ensure glass to metal contact is avoided. The clip design strategy can then be coordinated with any remedial waterproofing work. To provide reduced air infiltration and increased water penetration resistance, an aged lock-strip gasket system may be sealed along the exterior of the gasket.
Typical wet seals consist of a bead of neutral cure silicone sealant tooled between the gasket and the exterior surface of the glass. These joints are tooled to a triangular fillet profile to seal the gasket to the glass. Typical bridge seal work at gasket splices and transitions is intended to seal voids and cracks at the exterior of the gasket.
Generally, black neutral cure sealants are used in these applications due to potential staining of the sealant from contact with the aged gasket and to mask the repairs. Along with installation of remedial sealants the exterior lock-strip gasket system may be coated with silicone elastomeric coating or covered with extruded silicone sheet to lessen the exposure of the gasket rubber to additional weathering.
Silicone sealant manufacturers whose products are generally used for wet seal and bridge sealant work offer silicone elastomeric coatings generally used for painting opaque exterior walls. These coatings have been used with success on exterior lock-strip gasket applications. Coating the gaskets with a silicone elastomeric provide benefits such as encapsulating the gasket to reduce carbon black and other contaminants from staining glass and adjacent finishes, as well as protection from UV to slow the degradation of the rubber.
Another option in covering existing lock-strip gaskets is to use preformed extruded silicone sheet membrane. Silicone sealant manufacturers have developed products specialized for this application and include shape profiles that accommodate wet seal installation at glass perimeters and gasket corner conditions.
Silicone sheet covering of the gasket system is generally more costly than coating with silicone elastomeric, but there are additional benefits to take into consideration.
The silicone sheet membrane is advantageous from a long term performance and durability perspective, and since the product is available in various colors this gives the building owner the ability to change the aesthetic of the facade.
In addition, the profile of the extrusion makes it possible to encapsulate gasket reinforcement clips to improve the appearance of the facade. Other options available include the addition of new aluminum trim color caps installed as part of a lock-strip gasket wet seal remediation. These would be similar to the silicone sheet products in the resulting aesthetics, however they are generally attached by mechanical means using a retaining clip system similar to that used to secure the system but with a modified profile that would accept an aluminum cover cap.
When replacing gaskets, it is critical to understand that RMA Rubber Manufacturers Association tolerance for the production of rubber products, including lock-strip gaskets, is not the same as the tolerances used in the production of glass and insulating glazing units. Tolerance in rubber product production is based on the degree of reproducibility of given dimensions.
