Perfect lintel anchorage<\/h3>\n\n\n

The concrete in the lintel ensures that the box is perfectly anchored by entering the pockets every 30 cm. The steel mesh can be removed to complete the fixing in cases of heavy stress (corner boxes). <\/p>\n<\/div>\n<\/div>\n\n\n\n

4 finishes<\/h2>\n\n\n

The outer casing of each model is available in 4 finishes. The inner wall is usually made of smooth or structured polystyrene.<\/p>\n\n\n\n

\n
\n
\n
\"\"<\/figure>\n<\/div>\n\n\n\n
\n

Polystyrene<\/h3>\n\n\n

By default, the finish is made from the same polystyrene as the shell. The wall is structured (or ribbed) for better adhesion of the finishing plaster.<\/p>\n<\/div>\n<\/div>\n<\/div>\n\n\n\n

\n
\n

Wood fibre cement<\/h3>\n\n\n

La finition bois-ciment est la plus demand\u00e9e et offre une excellente accroche d’enduit. Les plaques de fibre de 5 mm sont coll\u00e9es \u00e0 la paroi lors de la fabrication.<\/p>\n<\/div>\n<\/div>\n\n\n\n

Terracotta<\/h3>\n\n\n

The terracotta finish is popular for top-of-the-range insulated enclosures, and provides a finish that matches the building's fa\u00e7ade. The 8 mm terracotta sheets are glued to the wall during manufacture.<\/p>\n<\/div>\n<\/div>\n<\/div>\n\n\n\n

Primer<\/h3>\n\n\n

The primer finish saves time when finishing on site. The primer is available in a choice of grey or terracotta colours.<\/p>\n<\/div>\n<\/div>\n\n\n\n
