Kingspan Kooltherm K106 Full-Fill Cavity Board

K106 is a phenolic full-fill cavity board for masonry walls where the insulation is designed to occupy the cavity width covered by the system approval.

Its 1200 x 450mm size suits standard wall-tie spacing and the 0.018 W/mK declared conductivity keeps the required thickness lower than most PIR cavity boards.

Use the correct retaining clips, keep joints closed and protect the exposed board edges as the outer leaf rises.

Why Choose This Product?

Choose K106 when the wall design calls for a high-performance full-fill cavity solution with a 10mm residual cavity. Its 0.019 W/mK phenolic core reaches a given thermal resistance with less thickness than standard 0.022 W/mK PIR.

Key Features

·        1200 x 450mm boards

·        Declared conductivity: 0.018 W/mK

·        Full-fill masonry cavity application

·        Low-emissivity foil facings

Common Uses

·        New-build cavity walls

·        Extensions using a full-fill cavity design

Installation

Cut boards or rolls accurately, close every joint and keep the insulation layer continuous at corners, openings and service penetrations. Use the fixings, tapes, membranes and covering layers stated for the selected construction.

Before You Install

·        Mixing up full-fill and partial-fill products.

·        Selecting a thickness without checking cavity width and the required residual cavity.

·        Leaving open joints or mortar droppings on board edges.

·        Using the wrong retaining clips or wall-tie detail.

Frequently Asked Questions

Is K106 a full-fill or partial-fill cavity board?

K106 is used as an advanced full-fill cavity solution with a 10mm residual cavity. It should not be listed as an ordinary partial-fill board.

What is the thermal conductivity?

The declared thermal conductivity is 0.019 W/mK.

How much does one 90mm pack cover?

A 90mm pack contains four 1200 x 450mm boards and covers 2.16m².

Can I choose any pack quantity?

No. Pack quantity is fixed by Kingspan for each thickness. Shopify should not offer invented pack-quantity options.

Is K108 the same product?

No. K108 is a partial-fill cavity board; K106 is the advanced full-fill solution.

What You'll Need

·        Correct wall ties

·        Insulation retaining clips
