Skylight Seals and Load Requirements

Skylight SealsSkylight seals from Elasto Proxy can meet requirements for dead loads, live loads, local maintenance loads, and wind compression loads.

Skylights are windows that are installed in a building’s roof or ceiling. They admit natural light, support passive solar heating, and provide a visual connection to the outdoor environment. Skylights feature large spans of glass, but there’s more to these windows than meets the eye. Glass loads can be heavy, and wind loads can add weight and pressure to skylight panels. If heavy loads cause a skylight to collapse, people can get hurt. Serious damage to a building’s interior can result, too. Continue reading Skylight Seals and Load Requirements

Sound Barriers for Acoustic Insulation

Sound BarriersElasto Proxy explains what engineers need to consider when choosing sound barriers.  This article is the third in a multi-part series about acoustic insulation.

Sound barriers are soundproofing materials that reflect little or no noise. They usually contain dense but flexible mats and one or more layers of acoustical foams such as melamine. Various facing materials are also used for attenuation, protection, and decoration. Sound barriers are designed to achieve maximum attenuation over a broad frequency range, but they can impart other important properties. For example, some sound barriers offer resistance to fire and fluids. Other emit low levels of smoke while burning. Continue reading Sound Barriers for Acoustic Insulation

Sound Transmission Class (STC) and Acoustic Insulation

sound transmission classSound transmission class (STC) describes the ability of a product or material to stop the transmission of airborne sound. Since the 1960s, STC ratings have been used to describe the acoustical properties of ceilings, walls, floors, and doors. Today, STC values are provided for acoustic insulation made from a single material, and for multi-layer composites that are sandwiched together. Higher STC numbers are generally better, but there are exceptions to this rule – and other factors to consider as well.

In this article from Elasto Proxy, you’ll learn what STC is and how it’s measured. For starters, we’ll cover some basic concepts about sound, vibrations that travel through the air or another medium (such as a wall) and can be heard by the human ear. Along the way, it’s important to remember that sound can also be reflected inward (such as within a metal enclosure) and cause vibrations. So while preventing the transmission of unwanted sound (noise) is important, you may face other design challenges, too. Continue reading Sound Transmission Class (STC) and Acoustic Insulation

Custom Weather Stripping for Doors and Windows

custom weather strippingCustom weather stripping from Elasto Proxy can meet the challenges of static or dynamic sealing in hot or cold weather conditions.

Here in the northern hemisphere, the days are becoming colder. In Canada, where Elasto Proxy is headquartered, the snows will arrive long before December 21, the first day of winter. At offices and factories across North America, doors and windows that let warm air out and cold air in mean higher heating costs. Leaky door and windows can also make occupants less comfortable and workers less productive.

Standard weather stripping can help, but what if your sealing and insulation application requires a specialized solution? After all, off-the-shelf rubber products aren’t designed and manufactured with your specific needs in mind. For a custom sealing solution you can count on, choose weather stripping from Elasto Proxy. All weather stripping isn’t the same, and selecting a custom-fabricated rubber product can save you time and money in the end. Continue reading Custom Weather Stripping for Doors and Windows

Silicone Hatch Seals Resist Compression and Temperature

Silicone Sponge ST-375-23-SM

Elasto Proxy custom-fabricates silicone hatch seals for demanding applications. These specialty gaskets support superior sealing with good compression set and temperature resistance.

Gasket designers want rubber hatch seals that are as tough as the vehicles, equipment, and infrastructure that need them. If a hatch seal can’t withstand compression, it may over-compress and admit wind, water, dirt, or mud. If a hatch seal can’t withstand a wide range of temperatures and outdoor environmental conditions, seal failure can result, too. If you need hatch seals for military vehicles, mobile equipment, marine applications, or HVAC systems, there’s plenty to think about. Fortunately, help is available.

For every hatch seal design, compound selection is critical. As readers of this blog learned last March, choosing the right rubber won’t stop enemy fire, but choosing the wrong rubber can result in over-compressed hatch seals on military vehicles. That’s why although neoprene rubber offers an excellent balance of material properties, this elastomer wasn’t the best choice for the military gaskets that Elasto Proxy inspected. After examining the results of over-compression, we recommended silicone sponge rubber seals instead. Is this same elastomer right for your application, too? Continue reading Silicone Hatch Seals Resist Compression and Temperature

Polystyrene Foams for Building and Construction

Polystyrene FoamsElasto Proxy custom-fabricates polystyrene foams for building and construction projects that require strong, lightweight, waterproof, and mold-resistant materials.

Home builders and general contractors need waterproof building materials for kitchens and bathrooms. Commercial construction companies also need specialized materials that can prevent water from weakening structures such as shower frames or sink backsplashes. There are several different categories of water damage, but even the least harmful type (Class 1) can mean costly repairs or renovations.

Water damage doesn’t just rot and weaken built structures, however. Moisture promotes the growth of mold and other organisms that can harm human health. For example, exposure to so-called “black mold” may cause skin rashes or respiratory distress, especially in children and people with compromised immune systems. Sometimes, these toxic molds remain hidden behind tiles or beneath flooring for years. Continue reading Polystyrene Foams for Building and Construction

Custom Skylight Seals Case Study

Custom Skylight SealCustom skylight seals need to meet demanding environmental and load testing requirements. When a skylight company faced a sealing challenge, Elasto Proxy provided the perfect solution on a tight timetable.

Skylights are specialized windows that builders install in a roof or ceiling. They admit natural light, provide a visual connection to the outdoor environment, and support passive solar heating. Skylights can help reduce energy costs, but their benefits go beyond sustainability. For example, the giant domed skylights found atop some commercial buildings are designed to enhance the occupants’ overall experience. By combining art with infrastructure, these complex structures truly illustrate the art of sealing. If a skylight fails, however, property damage and personal injury may result.

How Elasto Proxy Supports Infrastructure Projects

infrastructure projectsInfrastructure projects need sealing and insulation solutions that reduce risk and strengthen product designs. That’s why the industry chooses Elasto Proxy.

Buildings are more than just enclosed structures. In addition to foundations, roofing, and exterior walls, they contain components such as doors, windows, flooring, and lighting fixtures. Industrial, commercial, and residential buildings also include non-structural systems such as HVAC, plumbing, electrical power, and fire protection. Together, all of these components and systems represent infrastructure – and infrastructure needs sealing and insulation from Elasto Proxy.

Fiberglass gaskets are used in high-temperature environments. Elasto Proxy custom-fabricates fiberglass insulation and sealing solutions that meet all of your application requirements.

Furnaces, boilers, stoves, vehicles, and lighting all have something in common. They require high-temperature gaskets for sealing and insulation. Typically, these heat-resistant gaskets are part of a larger assembly or system. For example, a gas furnace may contain heat exchangers made of metal plates and high-temperature gaskets. A variable-speed blower creates a vacuum, induces a draft, and forces hot air past the primary and secondary heat exchangers, which transfer heat between two fluids. The heat exchanger gaskets aren’t the only components in this complex system, but they play an important role.

For engineers, choosing the right materials for heat-resistant gaskets is an essential design consideration. It’s also important to select gasket materials with the right environmental resistance, but without “over-engineering” the part based on actual service temperatures. As an experienced gasket fabricator, Elasto Proxy can recommend the right rubber or non-rubber material for your high-temperature application. Using water jet cutting, we convert gasket materials cost-effectively without metal dies or tooling charges. Our skilled production personnel perform gasket bonding or joining operations with precision. Continue reading Fiberglass Gaskets for High-Temperature Sealing and Insulation
