Ventilated facades: masonry wall
Install slabs tight to the masonry wall. Use one layer of PAROC WPS 1n, or multi-layers with PAROC eXtra and PAROC WPS 3n.
Install PAROC WPS 1n insulation with butt joints by using mechanical fasteners. Select the fasteners according to the characteristics of the massive wall. Install the fasteners during bricklaying or at the same time with PAROC WPS 1n slabs.
When installing fasteners with a PAROC WPS 1n slab, drill a hole with a Ø 6 mm and a depth of 35 – 40 mm through the slab to the masonry wall. Plug a stainless steel bond into the hole and snap the anchor to the masonry wall by using a punch-tool. Press a washer to the bond so that the PAROC WPS 1n slab is well attached to the structure. Normally, four fasteners are required. Corners and the spaces around windows and doors require more fasteners.
When insulation is done in several layers with PAROC eXtra and PAROC WPS 3n, press PAROC eXtra slabs through the brick bond installed during bricklaying. Make a small slash on the PAROC WPS 3n facing in order to get brick bond through the facing and ease the installation of the PAROC WPS 3n slab. Press anchor washers to the bond in order to firmly attach the insulation to the masonry.
For air tightness in the outer corners, use PAROC XST 021 wide corner tape. Seal the slab seams with PAROC XST 020 tape.
Timber frame walls
(+ 50 mm studding inside, wind protection slab)
To ensure that insulation fills the entire space, cut the PAROC eXtra slabs with 2 – 5 mm of excess width.
Install PAROC eXtra slabs between the timber frames. Use whole slabs and install the edges carefully. Seal the joints around windows and doors with PAROC XSI 006 caulking band. Use the blade of the cutting knife to ensure that installation fills the entire timber frame.
Note: If PAROC eXtra slabs are installed after the wind protection slabs (e.g., PAROC WAS 25, PAROC WPS 3), there is a risk of round corners/edges, which results in thermal loss.
