Window Design for Energy Efficiency and Performance
A range of design features and technologies enhance the energy efficiency, durability, aesthetics, and functionality of windows. When selecting new windows, consider the frame materials, glazing or glass features, gas fills and spacers, and the type of operation. These elements contribute to the window’s energy-related properties. Look for an NFRC label to assess and compare the energy performance of different windows.

Frame Material Selection
2-Pane Configuration Standard option: 2-pane setup with argon gas filling for improved thermal insulation. Thermal insulation value (Ug) = 1.1 W/m²K, with the possibility to achieve values as low as 0.7 W/m²K.
3-Pane Configuration Standard option: 3-pane setup with double chamber and argon gas filling. Thermal insulation value (Ug) = 0.7 W/m²K, with the potential to reach values as low as 0.5 W/m²K.
- ›Aluminum: Known for its strength and low maintenance, aluminum frames benefit from a thermal break to improve insulation.
- ›Composite: Made from wood-polymer blends or wood composites, these frames offer excellent insulation, moisture resistance, and stability.
- ›Fiberglass: Highly durable and energy-efficient, fiberglass frames can be further insulated for top thermal performance.
- ›Vinyl: Low-maintenance and well-insulated, vinyl frames can be filled with insulation, offering effective energy efficiency.
- ›Wood: Naturally insulating and aesthetically pleasing, wood frames may require maintenance but can be clad in aluminum or vinyl for durability.
Which glass for what you want?
Pick what matters to you and see how the right glass works — no jargon.
Akustex — acoustic glass
Laminated acoustic glass absorbs sound waves before they enter — up to 40% less street noise.
Hurricane-Resistant Glass
Bulletproof Glass
Bulletproof glass is engineered to withstand high-impact forces, providing superior protection against ballistic threats. Made from multiple layers of laminated glass and polycarbonate, it absorbs and disperses energy, preventing penetration while maintaining visibility. Ideal for banks, government buildings, and high-security areas, this glazing solution ensures safety without compromising design or clarity.
Prioritizing Quality, Innovation, and Customer Satisfaction
Our premium glazing solutions offer more than protection; they deliver peace of mind by combining refined elegance, enhanced security, and exceptional energy efficiency.
Window Operating Types
- ›Awning & Casement: Hinged and sealed tightly when closed.
- ›Fixed Windows: Non-operable, airtight option.
- ›Sliding & Hung Windows: Slightly higher air leakage but offer flexible ventilation options.
Security and Safety Glass Options
Security glass options are designed to deter intrusion and ensure user safety.
- ›Anti-Burglary Glass: Layers of PVB film increase resistance.
- ›Fire-Resistant Glass: Maintains integrity under high temperatures.
Glazing Profiles and Thickness Options
Different profiles allow for variable glazing thickness, tailored to insulation needs.
- ›Profile 68: Supports up to 40 mm glazing.
- ›Profile 78: Accepts up to 50 mm glazing.
- ›Profile 92: Accommodates up to 60 mm glazing for top insulation.
Applications of Transom Bars in Architectural Design
- ›Modern Architecture: Adds aesthetic value and visual appeal.
- ›Enhanced Appearance: Improves window and façade aesthetics.
- ›Architectural Character: Provides distinctive style and personality.
- ›Historic Renovations: Maintains original window aesthetics in larger pane setups.
Gas Fills and Spacers
Gas fills, such as argon or krypton, are inserted between glazing layers to improve insulation by reducing heat transfer. Spacers, often “warm edge” types, help maintain a consistent gap between panes, minimize condensation, and further improve U-factor.

Choosing Glazing Types for Performance
Begin by selecting the ideal glazing type to meet energy, sound, and safety needs. Options include insulating, laminated, tempered, and sound-absorbing glass, each offering specific benefits for thermal efficiency, durability, and noise reduction. This first step sets the foundation for optimal indoor comfort and resilience.
Specialized Coatings for Enhanced Efficiency
Add high-performance coatings like Low-E (Low-Emissivity) or spectrally selective layers, which minimize energy loss and control solar heat gain. These coatings improve the insulation value and can be customized for different climates, reducing energy costs and creating a comfortable environment throughout the year.
Gas-Filled Insulation and Spacer Technologies
Utilize gas fillings, such as argon or krypton, between glass panes to further enhance thermal insulation. Combined with advanced spacer technologies, these features help reduce condensation and improve the overall energy efficiency of the glazing system, aligning with sustainable building standards.
Aesthetic and Functional Customization
Complete your glazing system with decorative and functional enhancements, including frosted, tinted, or patterned glass for privacy and style. Additional options like mullions or structural transom bars create visual interest and architectural appeal, allowing for a fully tailored look that meets both design and practical requirements.
How secure is secure? Safety glass, from everyday to bank-grade
Safety glass is rated by how much force it resists. Start with everyday protection and climb as your security needs grow.
Everyday safety
O2Won't break into dangerous shards. The baseline for family homes.
Basic break-in resistance
P2A / P2Laminated PVB layers slow down and deter an opportunist intruder.
Strong resistance
P4Four PVB layers stand up to repeated, determined blows.
High resistance
P3A / P4AResists tools — equivalent to a 150 mm steel wire mesh.
Maximum resistance
P5AWithstands serious force — equivalent to 12 mm steel bars.
Laminated safety film
VSGA film bonds the glass so it holds together when broken; available on one or both sides.
