UTHERM SARKING LE
- High thermal performance
- Easy to install
- Tongue and groove junctions reduces thermal bridging
Today a traditional roof is generally insulated with mineral wool from the inside. The advantage of this classic approach is that you can install the insulation between the rafters or spars, so there´s no loss of space. With a Sarking structure, the PIR insulation boards are installed on top of the supporting structure, so that thermal bridges are excluded and you create an airtight insulation shield.
UNILIN´s Sarking insulation boards are characterised by a high thermal insulation and thinner insulation structure thanks to a lambda value of 0.022 W/mK. The tongue-and-groove system ensures a perfect windtight fit. The boards can be installed quickly and easily, thanks to their light weight.
The Sarking PLUS PIR L boards are already equipped with an underlay felt on 1 side. Thanks to the self-adhesive overlap, you create a wind- and watertight roof in a single movement. The SARKING COMFORT PIR L board has on 1 side a wood fibre underlay board of 35 mm. With this you not only achieve better acoustics but the vapour-permeable underlay also guarantees an efficient moisture balance.
