  • Thermal Junction Details

    Knowing the importance of providing both a thermally efficient building while remaining cost efficient Metsec have the ability to assist with developing project specific thermal junction details in-house. Using thermal modelling software, Psi values can be calculated for a variety of different junction details that can be fed back into the clients SAP calculations.

    Thermal Junction Details

    Thermal Continuity Checklist

    T1. Ensure cavity barrier doesn't breach the insulation layer.
    T2. Ensure wall insulation is continued to top of wall plate.
    T3. Continue insulation in ceiling to outer edge of wall insulation.
    T4. Add additional insulation to face of wall above the cavity barrier to the same thickness as the general wall insulation.

    Air Tightness Checklist

    A1. Seal between the top of the plasterboard and the ceiling board.
    A2. Seal all penetrations through the air barrier using a flexible sealant.
