How Hi-Therm Lintels Improve Fabric-First Performance

This is especially relevant in the context of Earth Day, which highlights the importance of practical, scalable ways to improve sustainability across construction.

While insulation and airtightness are key, thermal bridging at junctions remains a critical and often under-addressed factor.

Hi-Therm lintels are designed to improve performance exactly where it matters most.

Reducing Thermal Bridging at Openings

Window and door openings are among the most common sources of heat loss. Standard steel lintels can create thermal bridges, weakening the overall thermal performance of the building fabric.

Hi-Therm lintels incorporate an integrated thermal break to reduce heat transfer at these junctions, helping to:

• Reduce thermal bridging at cavity wall openings
• Maintain insulation continuity across the structure
• Improve overall thermal performance

By addressing these weak points, they contribute directly to a more efficient and consistent building fabric.

Supporting Part L and SAP Performance

As Part L requirements become more stringent, reducing heat loss at junctions is essential.

Hi-Therm lintels help:

• Improve SAP calculations through better junction performance
• Reduce heat loss coefficients linked to thermal bridging
• Support compliance with Part L and future regulatory targets

This makes them a practical specification choice for developers and designers working towards higher performance standards.

Lower Energy Demand Through Better Fabric

Reducing thermal bridging has a measurable impact on energy use.

By improving fabric performance, Hi-Therm lintels contribute to:

• Lower space heating demand
• Reduced overall energy consumption
• More efficient building operation over time

This aligns directly with fabric-first principles, where performance is designed into the structure, not added later.

Improving Comfort and Reducing Risk

Thermal bridging doesn’t just affect energy, it impacts internal conditions.

Hi-Therm lintels help to:

• Maintain consistent internal surface temperatures
• Reduce the risk of condensation and mould growth
• Improve occupant comfort

These outcomes support both regulatory compliance and long-term building quality.

A Targeted Solution for Better Building Performance

As the industry moves towards higher standards under the Future Homes Standard, attention to junction detailing is increasingly important.

Hi-Therm lintels provide a focused solution, improving thermal performance at openings, reducing heat loss, and strengthening the building envelope.
