    agent that has zero ODP and low GWP

    Typical Construction:
    Where insulating externally or sheathing a frame construction, there are some simple design considerations that can be adopted to help reduce heat losses.
    The reveal linear thermal bridge can be avoided either by positioning the window frame so that its outer face is flush with the outer surface of the masonry wall, and overlapping the window frame with the external wall insulation. Or, if this is not possible, the linear thermal bridge can be reduced by insulating the reveal at jambs, head and sill. The key factor is the thermal resistance (R–value) of this insulation layer.
    Reveals should be designed to accommodate the 20 mm of Kingspan Kooltherm® K5 External Wall Board required to achieve an R–value of 0.6 m2.K/W, and the depth of the cladding system (see Figure 7).
    Heat loss through reveal junctions can also be reduced by internally accommodating 32.5 mm (min.) of Kingspan Kooltherm® K118 Insulated Plasterboard around the openings
    Where existing windows or doors are not replaced as part of renovation works, design and detailing should consider the potential for future replacement works.

    At ground floor junctions where Kingspan Kooltherm® K5 External Wall Board is used on an existing substrate, good practice is to extend the insulation below the starter rail as an insulated plinth to ground level (for example using Kingspan Purlcrete® chevron). Best practice would be to excavate and extend the external insulation below ground level by at least 300 mm below finished floor level to increase the heat flow path and reduce junction losses. A starter rail / track formed from a low conductivity material can also help to reduce losses through this junction.
    For a new build construction, where Kingspan Kooltherm® K5 External Wall Board is used to sheath a frame construction at the edge of ground floors, the distance between the top surface of the floor insulation or perimeter insulation upstand, and the bottom of the wall insulation must be a minimum of 150 / 225* mm for a concrete floor and 200 mm for a suspended timber floor. The further appropriate wall insulation extends past the floor insulation, the better the thermal performance of the junction between the wall and the floor will be.
    * 150 mm applies to the UK and 225 mm to the Republic of Ireland
