A closer look at structural thermal breaks:

Structural thermal breaks are specialized components which are integrated into a building’s envelope to specifically interrupt the flow of thermal energy between any adjacent building elements. They’re specially designed to reduce heat transfer and mitigate thermal bridges which occur when there’s a continuous path of high thermal conductivity between the exterior and interior surfaces of a building. Thermal bridging can lead to localized heat loss or heat gain resulting in energy inefficiency, increased heating and cooling costs and reduced comfort for visitors and occupants.

The main purpose of a structural thermal break is to create resistance in the thermal path created by the bridge, thereby reducing the direct conduction of heat between building components. By using a thermal break, the overall thermal performance of a building is enhanced, along with more positive energy efficiency levels and sustainability. They work towards effectively isolating the inside temperatures and reduce influence of additional fixings or penetrations to the building that may transfer temperatures.

Advantages of structural thermal breaks

Structural thermal breaks offer a range of benefits that positively impact the sustainability, energy efficiency and overall performance of a building. By addressing thermal bridging and minimizing heat transfer between building components, these innovative materials can provide tangible benefits for the building itself and its occupants or visitors. The main advantages of utilizing them are as follows:

Enhanced energy efficiency

One of the most significant advantages of incorporating a structural thermal break solution throughout a project is enhanced energy efficiency within the building. By reducing heat transfer and the occurrence of thermal bridges, these components can work towards maintaining a more stable indoor temperature which reduces the need for costly heating or cooling methods. As a result, buildings with thermal breaks require much less energy to maintain comfortable indoor conditions, leading to decreased utility costs and lower energy consumption. If the inside temperatures are more agreeable and can stay at a preferred temperature for longer, there’s less need for any expensive heating and air condition solutions to be used as frequently.

Lower heating and cooling expenses

Reduced energy consumption translates to lower cooling expenses for the building owner, and occupants too. With less heat loss being experienced during colder months, and a reduction in heat gain in the hotter months, buildings that contain effective thermal break solutions throughout can reap the benefits of improved thermal performance all year round.

Reduction of condensation issues

Condensation is a key issue to address within a building. Thermal breaks work towards maintaining a higher surface temperature on the interior side of building components, reducing the risk of any condensation forming. If a thermal bridge is present, they can easily lead to cold spots on interior walls which is where condensation will appear when met with the warm and moist interior air temperatures. By reducing the chances of condensation forming on interior walls, the potential for mold growth, material degradation and any other moisture related issues is significantly reduced too, contributing to a healthier indoor environment.

Improved indoor comfort

By eliminating thermal bridging and cold spots near connections and building elements, structural thermal breaks create a more consistent and enjoyable, comfortable living space or indoor environment. Occupants experience fewer temperature fluctuations, leading to increased overall satisfaction with the building.

Long-term structural integrity

Thermal bridging can lead to localized stress and temperature-related wear and tear on building components, associated with condensation, potentially causing detrimental effects to their structural integrity over time. With the use of a structural thermal break, the stress on a building’s structure is reduced, extending the lifespan of critical building elements and minimizing any expensive repair and maintenance costs.

Sustainability and green building certifications

The addition of thermal breaks aligns with sustainable building practices and green design initiatives. Buildings featuring these energy-saving materials are more likely to achieve green building certifications and meet ever advancing energy codes. The USGBC’s LEED program and Passive House both recognize thermal bridging mitigation as a major milestone in building efficiency. They also work towards eradicating the need for any costly renovation projects to improve efficiency over time or in the future.

Reduced carbon footprint

As buildings account for a significant portion of global energy consumption and greenhouse gas emissions, implementing structural thermal breaks can help work towards a reduced carbon footprint. By optimizing energy use, these materials support environmentally responsible construction and operation practices.

Flexibility in design

Structural thermal breaks come in a variety of forms, offering architects and designers flexibility in their application. They can be customized to suit various t building types, different connections, architectural styles, structural configurations and more to allow for seamless integration into a diverse range of construction projects.

Compliance with building codes and regulations

Many building codes and energy efficiency regulations now emphasize the importance of addressing thermal bridging. By incorporating structural thermal breaks, builders and developers can comply with these requirements and ensure that projects they’re working on will meet all the necessary standards.

Promotion of sustainable building culture

By embracing the most innovative energy solutions on the market, the construction industry fosters a culture of sustainability and responsible building practices. This cultural shift ultimately leads to a more sustainable and environmentally conscious future for the building industry.

Developments in structural thermal breaks

In the quest for energy efficient structures and sustainable buildings, constant innovation in construction materials and techniques plays a pivotal role. One area that has seen significant advancements in the world of thermal breaks. These intelligent materials have undergone remarkable developments in recent years, offering improved thermal performance, increased cost-effectiveness and enhanced sustainability. 

Engineers can now design thermal breaks that will provide thermal separation, alongside the ability to transfer loads between building components. This integration is key for structural stability, but also effectively minimizes thermal bridging.

This is particularly beneficial for building connections like façades and balconies, where both thermal performance and structural support are crucial. This approach optimizes the use of materials and streamlines the design process.

Continuous insulation

Continuous insulation systems have surfaced as a real game-changer in the fight against thermal bridging. They provide uninterrupted thermal insulation across the entirety of a building envelope, ensuring a consistent thermal barrier. Whether in masonry construction, curtain walls, or other façade systems, continuous insulation effectively reduces any potential heat loss or gain, resulting in remarkable efficiency improvement levels.

Continuous insulation solutions, when combined with other innovations like customisable thermal break pads and advanced insulating materials, create a highly efficient thermal envelope that complies with even the most stringent energy codes, regulations and certifications.
