Passivhaus buildings using SIPs

Passivhaus insulation starts with the right structure — and that’s where SIPs deliver. Our high-performance panels offer exceptional airtightness, thermal efficiency, and speed of build, making them ideal for low-energy homes.

Our approach focuses on creating an airtight, thermally efficient building envelope that minimises heat loss and reduces energy demand. By using SIPs as both structure and insulation, we streamline the construction process while meeting the rigorous requirements of low-energy and passive building principles.

Why use Fabric First building methods?

• Maximises air-tightness
• Amazing for insulation
• Optimise solar gain through the provision of openings and shading
• Use the thermal mass of the building fabric
• Use energy from occupants, electronic devices, cookers and so on

The Key Concepts of adopting Fabric First in your next project

As SIP contractors we understand all aspects of buildings designed and constructed using the fabric first approach, and their aim to minimise the need for energy consumption through methods such as:

• Maximising air-tightness

• Using Super-high insulation

• Optimising solar gain through the provision of openings and shading

• Optimising natural ventilation

• Using the thermal mass of the building fabric

• Using energy from occupants, electronic devices, cookers and so on

Kingspan TEK for Passivhaus Insulating

Kingspan TEK Building System panels are ideal for Passivhaus-standard homes, combining structural strength with outstanding thermal performance. As a structural insulated panel (SIP) system, Kingspan TEK offers excellent airtightness and insulation, helping to meet the demanding energy efficiency targets of low-energy and Passivhaus builds. The system is fully BBA-certified and recognised by major building warranty providers, with proven compliance across all current Building Regulations.

As a trusted and experienced Kingspan TEK partner, we’ve delivered numerous successful projects in collaboration with contractors, architects, and developers—many of whom return to work with us again, which we see as the highest endorsement of our work.
