Kingspan K110

Kooltherm K110 is ideal when you need high-performance overhead insulation – on ceilings, soffits, or structural slabs – but do not want layers of bulky build-up. It is a slim, rigid board that packs strong thermal protection into a neat, manageable sheet.

K110 insulation is designed to stay tight to the underside of concrete or structural elements, helping reduce heat loss while keeping overall ceiling build-up to a minimum.

What Is K110 Kingspan Insulation?

Kingspan Kooltherm K110 is built around a rigid, fibre‑free phenolic foam core. That core is lightweight yet dense, with a closed-cell phenolic insulation structure, which makes it a top performer while keeping the board manageable on site.

On one side, the foam is covered with a glass‑tissue facing (concealed inner side), and on the other side, a low-emissivity composite foil facing (exposed outer side). Both are bonded firmly to the core.

It achieves a thermal conductivity (λ‑value) of 0.019 W/m·K, putting it among the most efficient rigid insulation panels for ceilings and soffits.

Thanks to the efficient core and facings, it offers strong thin‑profile insulation, where thick walls are not necessary to achieve good thermal resistance.

What Is K110 Soffit Board Used For?

The K110 Kingspan board is primarily used in these overhead concrete and structural surfaces:

• Structural ceilings such as basements, car‑park decks, and mezzanine slabs where a solid deck above exists.
• Concrete soffits in loading bays or under buildings.

Benefits of Kingspan K110 Soffit Board

Here is why the K110 soffit board is a great pick for soffit or structural‑ceiling insulation:

1. Top‑class thermal efficiency in a slim board – K110 achieves a very low thermal conductivity (~ 0.019 W/m·K), providing strong insulation without thick layers.
2. Saves ceiling depth space – Its slim profile keeps soffits and ceilings neat rather than bulky, which is a big plus when head‑height or structural depth is limited.
3. Rigid, stable, and easy to handle – The fibre‑free phenolic foam core is rigid yet lightweight. That makes K110 easier to cut, lift, and repair than many alternatives for soffit or concrete‑slab insulation.
4. Resistant to moisture and air leakage – K110 withstands vapour and air movement quite well when installed according to manufacturer guidelines. So its insulating properties are reliable over time.
5. Fire performance and safety assurance – The board is FM‑approved to Class 1 (FM 4880) when installed correctly with recommended fixings, foil orientation, and taped joints, making it suitable for residential or commercial ceilings and soffits that need compliance.
6. Durable and long‑lasting – When properly fixed and not exposed to damaging solvents, K110 will maintain its insulation properties for many years – a solid long-term investment for ceilings, basements, car parks, and other concrete soffit areas.

How to fit Kingspan K110 insulation?

1. Cut through your Kooltherm K110 panels using a sharp knife or fine-toothed saw. Use a straight edge as your guide.
2. Position the boards tightly against the soffit, keeping all edges close together.
3. Use at least 11 mechanical fixings per 2.4 m × 1.2 m board, and spread them evenly.
4. Keep fixings 50–150 mm from edges and corners; avoid joints.
5. Tape all board joints and exposed edges with 70 mm+ self-adhesive foil tape.
6. Handle boards carefully – store them in a dry place and off the ground.
7. Work systematically across the area to maintain a continuous insulation layer.
8. Check that each board is fully supported and level before moving on.
