Do you love contemporary and sleek design? Then make sure to discover the Shades of Grey range. The lovely grey shades of these facing bricks accentuate the rigid lines of modern architectural projects. Their typical, unique colour is attributable to the reducing conditions in which they are fired. Shades of Grey also combines the soft textures of fired facing bricks with sleek and elegant straight lines.
In this way they are perfect for houses that are anything but ‘grey’, but stand out with their robust quality and surprising decorativeness. To this end, you can choose from the beautiful shades of Silex, Quartz, Basalt, Serena or a mix of your choosing.
|Size||Silex||Quartz||Basalt||Serena||Grey Blend||Twin Blend||Triple blend|
Usage (average number m²)
|Joint width ca. 12 mm||Joint width ca. 6 mm|
|Vecht-size||87 units||102 units|
|Waal-size||73 units||83 units|
The colour, texture and sanding of the facing bricks largely determine the appearance of the façade. In addition, the size, masonry bonds and the colour of the joints also play an important role in the look of the façade masonry Thanks to all of these options, the architect has great freedom of design, which also explains the continuing success of the facing brick. The complete installation instructions are available via Downloads.
- Mix the bricks and deliver all at once
Facing bricks are manufactured from clay, a natural material. Therefore, there may be minor differences between the various production runs. Therefore, it is always advisable to have the total amount needed delivered all at once. Always mix at least five packages and remove the bricks from the packages in a stepped pattern. In this way you achieve the best possible distribution of the colour nuances.
- Never lay bricks in the rain
While SVK facing bricks never discolour on their own, it can never be entirely excluded that some efflorescence will occur after executing the masonry work. These white veils occur while the construction is drying, when the water evaporates and the salt from the masonry appears on the surface.
Covering fresh masonry when it is raining can reduce the risk of efflorescence. In particular, covering the top edge and the upper 80 cm can be important in this regard. Know, however, that such efflorescence is benign and constitutes no problem for the quality of the masonry. The white veil is gradually washed away by rain.
- Select a masonry bond in which the joints of two successive layers of bricks jump at least 40 mm
Facing bricks are usually installed in a half-brick bond. The 1/3 or 1/4 bond may also be used. Always select a masonry bond in which the joints of two successive layers of bricks jump at least 40 mm. Is it not possible to adhere to this rule? Then you have to take special measures in order to guarantee the stability of the external cavity wall.
Recommended joint widths:
The joint width varies according to the desired appearance Here are a few recommended values:
|Adhesive mortar||5 to 6 mm|
|Thin-bed mortar||5 to 8 mm|
|Traditional masonry mortar||9 to 15 mm|
- Place sufficient wall ties
Place at least 5 stainless steel wall ties per m² and have them slope gently outwards. Distribute them evenly over the surface and provide additional ties for large wall breadths or for high walls.
- Ventilate the wall and insulate correctly
There is a ventilated air cavity between the inner and outer cavity wall that must be partially insulated. First lay the inner cavity wall, then install the insulation and only then build the exterior cavity wall.
The exterior wall is in fact a rain screen; it certainly should never we considered as a watertight construction. Ventilate the cavity using an open butt joint or other ventilation provisions.
Ensure that the insulation is solid, without air cracks or openings, connects to the interior cavity wall and follow the installation guidelines from the insulation manufacturer The actual air cavity between the insulation and facing brick must be at least 3 cm wide so that there is sufficient ventilation.
SVK facing bricks are manufactured from soft clay and are classified as ‘hand-made bricks’. According to EN 771-1 they belong to the type HD (High Density). The size, shape and technical characteristics meet the requirements established in EN 771-1.
