scratch removal
GlassRenu Introduces RenuDisk
GlassRenu® in Pacheco, Calif., a manufacturer of solutions for removing scratches and acid damage of any size and depth from all types of glass, has introduced its new conditioning disk technology (CDT). When used within the GlassRenu Scratch Removal process, the new abrasive allows users to not only reduce the time of repair but also reduce the material costs for repairs.

The company also says it’s offering an abrasive disk that actually performs better the more it is used. By allowing users to continue to use disks that otherwise would have been discarded after 15 square feet of use, the CDT RenuDisk are expected to provide excellent repair results for up to 1,000 square feet of glass. The cost savings of being able to reuse disks from repair to repair will allow users to save around 30 percent of the cost per repair.

The contractor grade scratch removal system is available as a field-ready kit with all tools and enough materials to repair approximately 500 square feet of glass.

Non-Fragmenting Blast-Resistant Glazing Among New Products From Sheffield
Sheffield Plastics in Sheffield, Mass., says its new blast-resistant product exceeds the current GSA and Department of Defense anti-terrorism force protection standards, including those with the highest levels of pressure loads and shock waves. According to the manufacturer, Makrolon® Hygard EX can withstand exterior blasts without splintering on the interior face of the material.  

It provides an improved level of optical quality in a highly UV-resistant material for sky-lighting and other overhead applications. Unlike glass and acrylic, which require thermal pre-forming, the material can be formed in place for more cost-effective curved glazing installations, according to the manufacturer.

Recycled Aluminum Now Standard on Wausau’s Products
Wausau Window and Wall Systems of Wausau, Wis., is supporting the U.S. Green Building Council LEED® Rating System™ criteria for recycled content by fabricating all of its products using aluminum extrusions exclusively from secondary billet that contain a minimum of 70 percent total recycled content.

In LEED-NC, Version 3, Materials and Resources Credits 4.1 and 4.2 require separate reporting for pre-consumer and post-consumer recycled content. These are used to calculate “combined” recycled content, equal to post-consumer plus one-half of pre-consumer recycled content. Depending upon the customer specification and extrusion source, Wausau’s recycled aluminum extrusions have a LEED combined content of 42 to 69 percent, with total recycled content of 70 to 83 percent.

Horton Offers Two New Door Systems for Airborne Infection Isolation Rooms
Many hospitals today are renovating and adding patient care areas designed specifically for isolation control as part of a focused initiative to reduce the possibility of patients spreading contagious airborne infectious diseases. Horton Automatics in Corpus Christi, Texas, is meeting this challenge by offering two new door systems that are tested to strict air infiltration standards and designed for airborne infection isolation rooms (AIIR).

The new 2000-IDS is an automatic trackless system designed with “Knowing Act” activation (touchless sensor or push plate), recessed pull handle, presence sensor, perimeter seals and self-closing operation. This model is available in unit widths ranging from 7 to 9 feet with large clear openings up to 48 inches. The system has excellent air infiltration test results easily meeting negative, positive or combination pressure airborne infection isolation room requirements.

Horton also offers a mechanical self-closing IDS that opens manually and self-closes. It features full perimeter seals and can be applied in any of the same medical installations as that of the 2000-IDS, but without the need for electrical power. In addition, the self-closing IDS has a positive latching handle and a hold-open feature.

Both systems may be used as a patient room when infection control is not required.

Solar Innovations Slides Out New Thermally Broken Products
Solar Innovations Inc. in Pine Grove, Pa., has released a new thermally broken Lift Slide product for door and window applications. At first glance, the Lift Slide door shares its appearance with the traditional sliding glass door, but it operates with ease and is designed to meet the growing trend of larger doors in commercial projects and homes.

A traditional sliding door requires more force to operate the large sizes specified by architects and often cannot meet high performance demands, but because of its high thermal, air and water performance, and ease of operation, the Lift Slide can. The key to its design is the lifting of the panel above the water seals, which allow for smooth, almost effortless operation. Each panel can weigh up to 440 pounds with standard hardware. Larger sizes are available with custom hardware.

To open or close the door, the operator simply lifts the handle up and walks with the panel, then turns down the handle again to lock the door in the desired location. Lowering the handle seals the gaskets tightly. The strong seal allows for a higher projected testing score for air, water, structural and thermal performance; the design currently is undergoing testing.

The Lift Slide doors are available in standard color selections; custom colors are available upon request. The system can also be finished with a variety of metal and wood cladding options. The new product is available in a variety of configurations.

Peerless Products and Benson Industries Submit Products for CMAST Database
The National Fenestration Rating Council (NFRC) announced that Peerless Products Inc. in Fort Scott, Kan., is the most recent frame component manufacturer to submit products into the Component Modeling Approach Software Tool (CMAST) database. This most recent addition brings the total number of frame component manufacturers with products in the database to six. The five other frame component manufacturers are:
• EFCO Corp. in Monett, Mo.;
• Kawneer North America in Norcross, Ga.;
• TRACO in Cranberry Township, Pa.;
• FM Graham in Merrill, Wis.; and
• Wausau Window and Wall Systems in Wausau, Wis.

In addition, Portland, Ore.-based Benson Industries LLC, a manufacturer of commercial fenestration products, including proprietary curtainwalls, skylights and storefronts, also has submitted its products into NFRC’s CMAST database.

IGMA Continues Harmonization with ISO Standard for Insulating Glass
The Insulating Glass Manufacturers Alliance (IGMA) announced the publication of ISO 20492, Parts 1, 2, 3 and 4 for insulating glass units. The ISO/TC 160/SC 1-WG4 Insulating Glass convened for the first time in 1995 and, according to IGMA, the standard’s publication represents years of dedicated effort by the industry.

In its announcement, IGMA extended special to the task group convener and its technical consultant Bill Lingnell of Lingnell Consulting Services and Jeff Haberer of Cardinal IG, who acted as the secretary for the group.

The standard is comprised of four parts:
• 20492-1 Glass in buildings—Insulating glass—Part 1: Durability of edge seals by climate tests;
• 20492-2 Glass in buildings—Insulating glass—Part 2: Chemical fogging tests;
• 20492-3 Glass in buildings—Insulating glass—Part 3: Gas concentration and gas leakage; and
• 20492-4 Glass in buildings—Insulating glass—Part 4: Methods of test for physical attributes of edge seals.

This standard combines the IG test methods and specifications of ASTM (E2188, E2189, and E2190) and EN 1279 parts 2, 3, 4 and sections of part 6.

YKK AP Expands Application of Sun Control System to Storefront Facades
YKK AP America in Austell, Ga., has expanded the application of its energy-efficient sun control system, ThermaShade, to include storefront facades. The industry’s only sunshade system to feature a thermal barrier, ThermaShade reduces solar heat gain to help lower the overall energy consumption of a building. ThermaShade also is available for curtainwall applications. Designers can now take advantage of the proven sun control system and apply it across the entire building facade, including storefronts and curtainwalls, to maintain a consistent appearance.

For simple installation, pre-engineered solutions are available in more than 100 configurations, including four standard outrigger designs, eight standard lower options and five standard fascia options.  An integral hook mechanism also is included on outriggers.

ThermaShade is part of YKK AP’s enerGfacade product line of energy-efficient, thermally broken solutions for the building envelope.
