Structural insulated sandwich roof panel with increased airtightness
Sandwich roof panels are composed of PIR insulation, a vapour barrier, an airtight timber fillet, an external 12 mm chipboard (on demand a 12 mm OSB possible) and a choice of internal board finishes.
| Application | Ventilated roof applications with a variety of finishes such tiles, slate, metal etc. |
| Installation | On purlins, with cross installation onto traditional trusses possible |
| Insulation | Polyisocyanurate (PIR) |
The PIR is covered on both sides with a multilayer laminate and has a density of ca. 32 kg/m³, a compressive strength of 0.20 N/mm², a water absorption capacity of max. 5.5 vol.% and a λ-value of 0.023 W/mK.
The Vapour Control Layer (VCL) is composed of a multi-layer gastight laminate.
There are 3 counterbattens per roof panel, composed of European pine in accordance with NEN 5466. The nominal dimensions are 20 x 30 mm. Optionally a variant without counter battens can be proposed in case a breathable membrane is applied on the Roof SW Easy Airtight panels.
The Easy Airtight system is composed of a patented airtight timber fillet which seals the connection between each panel. The fillet slots into a rebate (13 mm x 29 mm) precut into the PIR core just behind the internal finish. This rebate runs along the entire length of the panel and by using the USYSTEM accessories ensures "Passivhaus" levels of Airtightness.
