Kingspan Kooltherm K112, formerly known as Kingspan Kooltherm K12, is used between studs or as an insulation sheathing in both timber frame and steel frame walls. When installed in constructions Kooltherm K112 offers premium performance with a thermal conductivity as low as 0.018 W/mK.
Kingspan Kooltherm K112 is made up of a rigid phenolic core and is faced on both sides with low emissivity foil to give that low thermal conductivity. This makes this framing board insulation product perfect for new builds and refurbishment projects since it’s easy to install and handle. In a refurbishment project, this wall insulation can bring u-values even lower in areas where you previously might not have thought about insulating.
Resistant to the passage of water vapour, installing Kooltherm K112 as insulation sheathing can be a good idea to ensure other insulation types are kept safe and performing. This is also down to the fact that Kooltherm K112 isn’t affected by air infiltration.
K112 HOW TO INSULATE A TIMBER FRAME WALL – 3 EASY STEPS.
Ensure the timber frame has been installed correctly and the timber frame wall is ready for insulation to be applied.
Measure the space between each timber frame in the wall. Please note that in not all cavities within the wall will have same measurement. Each space should be measured separately, and the board should be cut to fit each individual space. Once you have taken your measurement, cut the insulation board to size using a fine-toothed saw.
Then push the insulation board in the space within the timber frame as far back as possible. Make sure the boards sit flush with the wall from top to bottom with no projections. If the board is fitted too tightly into the timber frames, the fine-toothed hand saw can be run down each side of the insulation board to achieve a better fit.
If the insulation is flush with the inside surface of the studs, treated softwood battens can be nailed to the side of the studs to prevent the insulation boards from moving too far into the cavity and to achieve a flush finish if the insulation boards are not as thick as the timer frame.
Continue until the timber frame wall studs are filled within insulation. Cut off can be used to fill any small gap in the insulation. Where insulation board have been butted together, a foil tape with I minimum measurement of 50mm can be applied to each join to avoid thermal bridging.
