Kingspan K112

Use Kooltherm K112 when building or upgrading a steel- or timber-framed wall and want top-notch insulation without bulky, awkward layering.

It is a thin but powerful framing panel – a neat, rigid sheet that delivers strong insulation while fitting neatly between studs or over a frame as sheathing.

K112 insulation keeps walls warm and efficient without adding unnecessary wall thickness.

What Is Kooltherm K112?

The core of the Kingspan K112 is made of rigid phenolic foam. The rigid phenolic foam is moisture-resistant and does not degrade when installed in accordance with the manufacturer’s guidance. Because it is a rigid, single-piece panel, K112 remains stable over time without settling or sagging when properly installed.

Both sides of the board have a low-emissivity composite foil facing bonded to the core, which reduces heat loss when installed in a wall assembly.

The panels’ thermal conductivity (λ-value) is just 0.019 W/m·K – a very low value for rigid insulation boards.

It comes in a variety of thicknesses – from 25mm to 150mm. Choose the thickness required to meet your target U-value.

What Is Kingspan Kooltherm K112 Used For?

Kooltherm K112 is installed for these applications:

• Framed walls (timber and steel) – This is the main use of the K112 framing panel. It fits naturally into modern framed construction without adding bulky layers.
• Between the studs or over the frame – Kooltherm K112 can be installed inside the stud zones or fixed as a sheathing layer.
• New builds, extensions, and refits – K112 helps builders achieve strong U-values when installing new walls or upgrading existing ones.
• Lightweight; easy to handle – K112 Kingspan is rigid, easy to cut, and quick to fix.

How to fit Kingspan K112 insulation?

1. Start with snug-fitting pieces – Cut each K112 panel so it sits tightly between the studs or against the frame, depending on whether you’re using it in the stud zone or as sheathing. A snug fit helps reduce air gaps.
2. Place the foil the right way – Fit the foil facing the cavity or the space you’re insulating. Check project specifications or Kingspan’s installation guide for correct orientation.
3. Fix securely but do not overtighten – For sheathing applications, use appropriate mechanical fixings and spread them evenly across the board. When installed between studs, K112 may stay in place by friction alone, though mechanical support may be required depending on the installation.
4. Keep joints tight – Line up the edges of each K112 framing board so they sit close together. For high airtightness, tape the joints with at least 70 mm wide self-adhesive foil tape to fully seal them.

How to cut K112 framing insulation?

1. Mark your line clearly – Use a straight edge to draw your cut line on the K112 Kingspan panel, especially if fitting it between studs where the fit needs to be snug.
2. Score first, then slice – For most thicknesses, score the foil side with a sharp knife, then press through the board in a couple of passes. For thicker Kooltherm K112, a fine-toothed saw gives a cleaner result.
3. Snap or separate gently – Once scored or partially cut, the board will break cleanly along the line, thanks to the rigid phenolic core in Kingspan K112.
4. Keep the installation tidy – Lightly sand or trim rough edges so the K112 insulation sits tight with no gaps.
5. Wear basic protection – Gloves and a dust mask are enough; Kooltherm does not shed itchy fibres, but it does create light dust when cut.

Where can you use K112?

1. Timber and steel framed wall assemblies – The K112 Kingspan board fits perfectly between studs or over the frame.
2. New builds and extensions – Use where you want top insulation without bulky walls.
3. Retrofits and upgrades – Swap in Kooltherm K112 to improve U-values in existing structures.
4. Slim-wall applications – Perfect for applications where high thermal performance is required but wall depth is limited.

Suitable wherever easy, reliable installation is required – K112 insulation is lightweight, rigid, and straightforward to fit.
