Construction and Materials
Oldcastle Building Envelope offers a range of glass products designed for various architectural applications. These products are engineered to meet specific performance requirements related to safety, security, energy efficiency, and aesthetics. The construction of these glass units typically involves the combination of multiple glass lites, often separated by a sealed space filled with inert gas or air. This construction method is known as insulating glass units (IGUs) or double-pane/triple-pane glazing.
Construction Details
- Insulating Glass Units (IGUs): These units are comprised of two or more panes of glass separated by a spacer. The edges are sealed to create a hermetically sealed chamber.
- Spacer Systems: The spacer separates the glass panes and can be constructed from materials like aluminum, stainless steel, or warm-edge composite materials. The type of spacer influences the thermal performance of the unit.
- Sealant: A primary and secondary seal are applied around the edges of the IGU. These seals are critical for preventing moisture ingress and the escape of the insulating gas, thereby maintaining the unit's performance.
- Laminated Glass: For safety and security applications, glass lites may be laminated. This involves bonding two or more panes of glass together with an interlayer, such as polyvinyl butyral (PVB) or ionoplast (IP).
- Tempered Glass: In applications where impact resistance and safety are paramount, tempered glass is used. This glass undergoes a heat treatment process that increases its strength and causes it to break into small, blunt pieces when fractured.
- Annealed Glass: This is the basic form of glass, which is less strong and breaks into sharp shards. It is often used as a base component in IGUs or laminated glass constructions.
Materials Used
- Glass: Various types of glass are utilized, including clear float glass, low-emissivity (Low-E) coated glass, tinted glass, and patterned glass. The specific type of glass is chosen based on desired aesthetic and performance characteristics like solar heat gain control and visible light transmission.
- Interlayers: For laminated glass, interlayers such as PVB or IP are used. These materials provide the bonding and safety features of laminated glass.
- Insulating Gases: The space between glass panes in IGUs can be filled with inert gases like argon or krypton. These gases have lower thermal conductivity than air, improving the insulating properties of the unit.
- Frame Materials (for specific product configurations): While the core product is the glass unit, it may be integrated into framed systems. Common frame materials include aluminum and vinyl, chosen for their durability and structural integrity.
Oldcastle Building Envelope's glass products are engineered with a focus on enhancing building performance, occupant comfort, and aesthetic appeal. The specific construction and materials used are tailored to the intended application, whether it be for commercial, institutional, or residential projects.

Glass Options
Oldcastle Building Envelope offers a comprehensive range of glass solutions designed to meet diverse architectural and performance requirements. Their product portfolio focuses on creating high-performance glass units that enhance the aesthetic appeal, energy efficiency, and safety of buildings.
Key glass options and technologies available from Oldcastle Building Envelope include:
- Insulated Glass Units (IGUs): These are fundamental to energy performance, comprising two or more panes of glass separated by a sealed space. This space is typically filled with air or an inert gas (like argon or krypton) to reduce heat transfer. IGUs can be customized with various glass types, coatings, and spacer technologies to achieve desired thermal and acoustic properties.
- Low-E (Low Emissivity) Coatings: Oldcastle Building Envelope utilizes advanced Low-E coatings that are microscopically thin and transparent. These coatings are applied to the glass surface to reflect infrared heat, keeping interiors cooler in the summer and warmer in the winter. This significantly improves the energy efficiency of buildings, reducing heating and cooling costs. Different types of Low-E coatings are available to suit various climate zones and performance objectives.
- Tinted Glass: For aesthetic control and solar heat gain reduction, tinted glass options are available. These tints are incorporated into the glass itself during manufacturing, providing a uniform color throughout the pane. Tinted glass can help reduce glare and improve occupant comfort by moderating the amount of solar radiation entering a building.
- Laminated Glass: This safety glass consists of two or more panes of glass bonded together with an interlayer, typically polyvinyl butyral (PVB). In the event of breakage, the glass fragments adhere to the interlayer, reducing the risk of injury. Laminated glass also offers enhanced acoustic performance and UV protection. It is a critical component for applications where safety and security are paramount.
- Tempered Glass: Also known as toughened glass, this is a type of safety glass that has undergone a special heat treatment process. When broken, tempered glass shatters into small, relatively harmless granular pieces, unlike sharp shards produced by regular glass. It is significantly stronger than standard glass and is used in applications requiring increased safety and impact resistance.
- Spacers: The choice of spacer material that separates the glass panes in an IGU is crucial for thermal performance. Oldcastle Building Envelope employs advanced spacer technologies, including warm-edge spacers. These materials have lower thermal conductivity than traditional aluminum spacers, minimizing heat loss or gain at the edge of the insulated glass unit and contributing to overall energy efficiency and preventing condensation.
- Specialty Glazing: Beyond the standard offerings, Oldcastle Building Envelope provides solutions for specialized applications, which may include options for enhanced acoustic performance, fire-rated glazing, or specific aesthetic finishes to meet unique project demands.
