Function in the ETICS system

Mechanical fixing to complement gluing

Mechanical fixing with dowels is additional to gluing, never an alternative. The dowels are applied after the bonding mortar has hardened, guaranteeing the long-term stability of the insulation. They must fulfil the requirements of ETAG 014.

The choice of fixings depends on the substrate and the insulating board. In the case of perimeter bonding with dots, the mechanical fixing must coincide with areas where there is bonding mortar on the board.

Selection criteria: support, insulation and exposure

The dowels are distributed around the perimeter of the board and in the centre, in a quantity of 6 to 8 per m². The length of the dowel must be at least 3 cm greater than the thickness of the insulating board. Drilling is carried out by the percussion method in concrete and solid brick substrates, and by the normal method in perforated brick substrates.

The bushes must be embedded in the panel. Any that become damaged or loose should be removed and replaced in a new hole, covering the remainder with insulating material or foam.

Bushing application

Procedure for mechanically fixing the insulating plates

The dowels are applied after the bonding mortar has set. Drilling is done by the hammer method in concrete and solid brick substrates, and by the normal method in perforated brick substrates. The screw is hammered or screwed in depending on the type of dowel.

The length of the dowel must be at least 3 cm greater than the thickness of the board. The dowels must be embedded in the insulating panel. Distribution of 6 to 8 dowels per m², in a T (EPS, ICB, XPS) or W (mineral wool) layout.

Plastic nail plugs (nylon)

Plastic nail plugs (nylon)

Standard mechanical fixing for ETICS systems on standard substrates.

Plastic body and reinforced polymer nail. Eliminates thermal bridging at the fixing point. Application by percussion. Suitable for concrete, solid brick and perforated brick substrates under normal exposure conditions.

Available in lengths from 70 to 260 mm. Boxes of 200 and 250 units.

Plastic nail plugs (nylon)

Steel nail bushes

The most demanding fixings for high-rise buildings, coastal areas and mineral wool systems.

Galvanised or stainless steel nails. Higher pull-out resistance than plastic nails. Suitable for buildings over 8 metres, high wind areas, substrates with less anchoring capacity and systems with mineral wool insulation. In the event of a fire, the steel nail keeps the boards fixed to the substrate even when the bonding mortar loses its capacity.

Available in the same lengths as the plastic nail versions. Boxes of 200 units.

Steel nail bushes

Bushings without nails

Bushing body for combining with specific nails as required by the project.

It allows the body of the dowel and the type of nail (plastic or steel) to be selected separately depending on the substrate and exposure conditions. Suitable for projects with specific specifications or when it is necessary to adapt the nail to the substrate after checking it on site.

Available in various lengths. Nails sold separately.

Bushings without nails

Special ETICS fixing

Fixing solutions for supports and conditions that standard bushes do not cover.

Fixing to wooden supports with a screw nail and mineral wool disc to eliminate thermal bridging. Fixing with chemical glue for high loads. Repair dowels for interventions in existing ETICS systems where the original holes are no longer usable.

Sold by the unit. Dimensions and configurations as per reference.

Special ETICS fixing

Bushing concealment

Caps and discs for concealing the fixing point on the insulation surface.

They eliminate the irregularity created by the head of the dowel before the reinforced busbar. Concealment ensures a uniform surface for the insulation, preventing visible marks on the final finish. Available in EPS and in versions compatible with current head diameters.

Construction details

Fixing specifications per type of support

Concrete and solid brick

Drilling by percussion method (hammer). Length of dowel: thickness of insulation + minimum 3 cm of anchorage in the support. Distribution: 6 to 8 dowels/m² in a T-shape.

Perforated brick

Drilling by normal method (without percussion). The internal geometry of the brick affects the anchorage. Validation of the load capacity is recommended. Distribution: 6 to 8 dowels/m².

Mineral wool (MW)

W-shaped distribution: 3 dowels per board, applied 5-10 cm from the sides of the board. Steel nails recommended for fire safety reasons.

Frequently Asked Questions

Technical questions about ETICS bushes

01    Is mechanical fixing compulsory in ETICS systems?

Mechanical fixing is additional to gluing, never an alternative. According to ETAG 014, its application depends on the conditions of the support, the height of the building and exposure to wind.

The length of the dowel must be at least 3 cm greater than the thickness of the insulating board, according to the procedure described in the ETICS Manual.

The plastic nail eliminates thermal bridging at the fixing point and is suitable for most everyday situations. The steel nail offers greater pull-out resistance and is suitable for high-rise buildings, high-wind areas, supports with lower anchoring capacity and mineral wool systems.

The standard quantity is 6 to 8 bushes/m². The number depends on the pull-out resistance, the type of insulating board, the height and position of the building. Reinforcement may be necessary in peripheral areas of the façade.

T-shaped layout for EPS, ICB and XPS boards: dowels at all board intersections and one in the centre. W-shaped layout for mineral wool: 3 dowels per board 5-10 cm from the sides.
