Surround ‘Greyish’

Cemintel Surround™ Greyish is based on the colour of concrete slurry. It is a dense, warm colour that works well on its own for a subdued effect, or as a complement to bolder colours.

The Cemintel Surround™ range responds to the preference for high performance, lightweight materials and the desire for buildings to enhance the environment where we live. From external façades to interior surfaces, Surround is a reinterpretation of cladding as we know it. With a core range of expertly curated neutral colours and discrete patterns, Surround allows buildings to look as one within their environment. Manufactured in Europe and prefinished, this range works equally well for interior and exterior façades with its sophisticated tactile surfaces, metallic finishes and subtle shades of marl, blue, grey and green. Based on the colour of concrete slurry, Greyish is a dense, warm colour that works well on its own for a subdued effect, or as a complement to bolder colours. Go bold with 4Ry1-w, a deep warm red, or be subtle with 2Yr1-w, a warm taupe.

Features

Panels come trimmed and sealed and can be installed horizontally or vertically using the Cemintel Commercial Expresswall® fixing system.
Only one rivet type used for both gliding and fixing points, making panel installation uncomplicated.
Prefinished coating is highly effective in repelling water, significantly reducing risk of delamination that may occur in freeze/thaw conditions.
Environmentally, the European manufacturing process of air curing means less CO² emissions. Panels can be recycled for soil conditioning and do not pose a health risk for landfill disposal.
Colour matched rivets available to accommodate differential movement between building structure and façade. They also provide a more seamless aesthetic.
Superior weather resistance and strength compared to other fibre cement panels of similar thickness.
Applied final sealant coating better withstands weathering over time, as well as environmental factors like pollution and microclimatic conditions, such as mould/algae.

CEMINTEL SURROUND™ PANELS ARE PREFINISHED FIBRE CEMENT PANELS THAT ARE COLOURED THROUGHOUT WITH A TRANSPARENT COATING (MARL) OR OPAQUE COATING (BASE, STRING, LEATHER, METAL) WHICH RESULTS IN A MORE NATURAL APPEARANCE AND DEPTH OF COLOUR THAN CAN BE ACHIEVED WITH A STANDARD SURFACE PAINTED FINISH.

Consisting primarily of Portland Cement, wood pulp, reinforcement fibres, air and water, panels have undergone a longer, natural air curing process and offer superior performance in terms of strength, density and durability. Available in a range of colours, textures & finishes, these square edged panels are manufactured in Europe under EN 12467 (fibre cement flat sheets) and are classified as Category A (for weather resistance), Class 4 (mechanical properties).
