For traditional masonry (façade bricks of Waal format type, laid with standard mortar), round cavity wall ties such as the Isolfix NT type are used. For thin-bed mortar or bonded façades, flat cavity wall ties are used (Isolfix NT-P type). For narrow façade bricks, L-shaped cavity wall ties are used (Isolfix NT-L type).

An impact anchor must be driven exactly to the end of the plug. With hollow bricks, there is always a risk that the anchor is driven too far and passes through the plug. In such cases, the anchoring of the cavity wall tie plug is no longer guaranteed. Always use a driving pipe, which you shorten to the length of the anchor minus the length of the plug see installation instructions. This way, you can always ensure that the anchor is at the exact depth of the plug.

An insulation plug has a round interior, whereas a cavity wall tie plug has a flattened interior. An insulation plug was designed to secure insulation without also holding the outer wall. However, insulation plugs are still often sold together with cavity wall ties. A cavity wall tie plug was specifically developed to anchor not only the insulation but also the façade.

Wall anchoring is an essential part of the construction and safety of buildings. It is designed to protect buildings from external forces, such as wind loads and earthquakes, by securing the structure to the foundation.

Only an L-shaped anchor (Isolfix NT-L) is accepted in Wienerberger's technical specifications for anchoring narrow façade bricks. At least 6 of these must be installed per m².

A cavity wall tie plug was specifically developed to ensure proper anchoring of the façade. This is important to prevent cracks in the façade. A cavity wall tie plug must meet declared pull-out values, depending on the type of inner wall brick used.

Insulation thickness + 60mm

300mm, suitable for insulation up to 240mm thick. If you are looking for a solution for even thicker insulation, it is best to send an email to info@connecton.be

A cavity wall tie must meet two important requirements: tensile and compressive strength, and corrosion resistance.

The corrosion resistance of cavity wall ties is described in Eurocode 6. To work 100% in compliance, cavity wall ties must be made of stainless steel AISI 316 (coastal regions) or stainless steel AISI 304 (inland).

Belgium is the only country in Europe where galvanized cavity wall ties are still sold. In principle, this does not comply with the European standard. In exceptional cases, after consulting the manufacturer, cavity wall ties with at least 265g of zinc can be used, but never in coastal areas or regions where road salt is used in winter.

A cavity wall tie plug must be drilled 60mm into the inner wall. You can also find this information in calculations on app.connecton.be

A cavity wall tie with a corrugated end does not need to be bent; the corrugations guarantee sufficient anchoring in the mortar.

No, for cavity wall ties, a cavity wall tie plug must always be used.

Depending on the application, insulation plugs with a plastic nail are used (no explicit forces on the plug), with a steel nail (...), or with a steel screw (in combination with facade plasters).

Cracks in the facade should be repaired because a crack can become an expansion joint that absorbs all tensions in the facade and can grow larger. This affects the stability of the facade, water resistance (risk of corrosion of cavity wall ties), and the insulation value of the house. Such cracks can be repaired using the Connecttwist range (link to technical datasheet).

Tile hooks are installed to prevent roof tiles from being blown off their place during storms.

Through this link, you can find a table with the correct type of tile hook for each type of tile. Which type of tile hook.

In coastal areas, stainless steel AISI 316 must always be used because salty air is very corrosive. In inland areas, AISI 304 or AISI 430 can be used.

C-Color hooks are slate hooks with an aesthetic coating. This makes them less visible on the roof, creating a more uniform appearance.

Slate hooks with a bump are mainly used with artificial slates. This prevents capillary moisture (rising moisture between the tiles via the hook) and ensures better ventilation.

To anchor slates, it is important that the nails do not rust over time. Therefore, it is always recommended to use copper nails or stainless steel nails (link to corrosion table).

Nails with a large head have a head that is 2.5 to 3 times the diameter of the nail shaft. Nails with an extra large head have a head that is 3.5 to 4 times the diameter of the nail shaft. The larger the head, the better the slate hook is secured.

Nails with a serrated shank have better adhesion than nails with a smooth shank, making them of higher quality.

Connectflex lead replacements replace traditional lead applications. The benefits include mainly the price, the fact that EPDM is available in different colors (red, gray, black) which provides an aesthetic advantage, and the fact that they come with a butyl adhesive layer for strong adhesion.

Connectflex can be applied on any surface, provided it is dust-free, grease-free, and dry. It is strongly recommended to always use a primer. You can find the installation instructions here. Connectflex installation instructions.

Connectflex should be stored and used at temperatures between 5 and 25°C. At higher temperatures, the butyl adhesive vulcanizes (adheres more strongly) to the protective film, making it harder to remove. When removing the film, always press the butyl against the EPDM with your thumb to ensure smooth removal of the film. Connectflex installation instructions.
