When it comes to sustainability and energy efficiency, there is no single answer to what sustainable buildings of the future will look like. One thing that is certain is that warm edge spacers play a key role in energy efficiency for buildings, and architects must understand what they do. 

Why should architects choose warm edge spacers for energy-efficient designs?

Warm edge spacers provide a critical solution to improving thermal performance, reducing heat loss, and enhancing the energy efficiency of buildings. Warm edge spacers are essential to achieving sustainable, high-performance architecture. Designed to improve the thermal efficiency of insulating glass units (IGUs), they help eliminate thermal bridging, minimise condensation, and support compliance with green building certifications like LEED. For architects focused on performance and design, Edgetech’s Super Spacer® offers a durable, high-performance alternative to traditional rigid spacers, aligning aesthetic vision with environmental responsibility. 

What makes warm edge spacers essential for modern architectural projects? 

Architects today face increasing pressure to meet the highest standards of sustainability, thermal efficiency, and occupant comfort. Warm edge spacers serve as a vital design component in reducing energy loss at the edge of the window and ensuring the superior energy performance of windows. These advanced spacer bars are redefining how architectural glazing is approached, maximising benefits without compromising on style or structural integrity. 

Understanding warm edge spacers in architecture

What is a warm edge spacer? 

A warm edge spacer is a spacer bar used in insulating glass units (IGUs) to separate the panes of glass and improve insulation at the glass edge. Unlike rigid spacers, which are typically made of metal and highly conductive, warm edge technology uses low thermal conductivity materials to reduce heat transfer, significantly improving the thermal performance of windows. 

Benefits of warm edge spacers for architects 

  1. Enhanced Energy Efficiency
  •          Reduces heat loss through the edge of the window
  •          Lowers energy bills and CO2 emissions
  •          Supports compliance with energy codes and building regulations

  1. Superior Thermal Comfort
  •          Maintains consistent indoor temperatures
  •          Eliminates cold zones near windows
  •          Supports a healthier indoor climate for occupants
  1. Improved Condensation Control
  •          Higher edge temperatures reduce condensation formation
  •          Prevents moisture damage and mould, preserving building integrity
  1. LEED and Green Building Compliance
  •          Warm edge technology contributes to LEED certification
  •          Promotes sustainable architecture and lower environmental impact
  1. Long-Term Durability and Cost Savings
  •          Durable and low-maintenance materials reduce lifecycle costs
  •          Helps buildings retain performance over decades

How Edgetech’s Super Spacer® redefines warm edge technology 

superspacer

Edgetech products, especially Super Spacer®, stand out in the glazing industry due to their superior performance, durability, and proven energy efficiency. Super Spacer® T-Spacer™ Premium Plus and TriSeal™ Flex models provide flexible and resilient solutions specifically designed for the commercial market and ideal for both double glazing and triple glazing installations. 

Key features include: 

  •          100% resilience to strong winds and pressure
  •          Elastic structural foam that adapts under climatic loads
  •          Performance-proven across large-format and curved glass applications
  •          Available in a wide range of spacer sizes to suit any project

Warm edge spacers in triple glazing 

 

For high-spec, modern builds, triple glazing is becoming standard. Incorporating warm edge spacers in triple glazed IGUs ensures: 

  •          Optimal thermal insulation
  •          Lower U-values
  •          Greater comfort and noise insulation
  •          Reinforced durability, even in extreme conditions

Energy performance at the window’s edge 

The edge of the window is a critical area of heat transfer. Warm edge spacer bars from Edgetech create an effective barrier, eliminating the thermal bridging found in traditional metal spacers. This innovation delivers uniform thermal conductivity, balanced temperatures across the full glass unit, reduced energy loss and greater energy savings. 

Supporting flexible and sustainable building design with warm edge spacers 

Modern architectural designs demand versatility. Edgetech’s flexible spacer systems are perfect for: 

  •          Curved panes and complex window geometries
  •          Large-scale glazing installations
  •          Façade designs that demand both form and function

Given that nearly 40% of global emissions come from buildings, the drive for sustainable design is essential. Warm edge technology plays a pivotal role by: 

  •          Reducing the carbon footprint of buildings
  •          Minimising resource consumption during production
  •          Improving long-term sustainability without sacrificing design goals

Meeting ESG standards
