DKTN, insulation, aesthetics and durability for facades

The Zeeduin renovation project is situated on the corner of Franslaan with Lefebvrestraat in Nieuwpoort. After a few decades, the façades - covered with relatively thin prefab silex concrete elements - showed concrete damage due to carbonation. The client and architect opted for a total renovation for the façades, with 4 mm thick DKTN Slim plates by Cosentino, glued on a ventilated aluminium support structure.

The apartment building dates back to the 1970s and has 6 above-ground floors. The gallery terraces, made of in situ concrete with the floor slab running from the inside to the outside without thermal interruption, were fitted with a mortar-bed tiling. Water penetration caused concrete damage and general degradation of the concrete coating. The absence of façade and roof insulation also contributed to a total renovation.

DKTN Slim, 4mm full of possibilities

A light façade cladding had to give the building a new, sleek and contemporary zest. This resulted in the choice of DKTN Slim plates (with a thickness of 4 mm), glued to an aluminium carrier. “This way the façade could be insulated to a maximum without bringing the façade surface too far forward,” according to the architectural engineer Ignace Deconinck of the eponymous Architecten Expertisebureau from Veurne.

A small balcony construction with a walking zone was provided for the apartments on the façade corner - with in the original condition only a balustrade in the façade surface. Not evident from a technical point of view. Good coordination (including dimensions and planning) between the main contractor (Aquastra), the balustrades subcontractor (Aluform) and the façade cladding subcontractor (Murex Stone) was required. After concrete repair, the gallery terraces were fitted with a new reinforced terrace compaction system and glass balustrades with front mounting of the uprights.

Nayla, an off-white full of nuances

The architect opted for a dark-coloured base (the ground floor) and a light superstructure to give the floors a more floating effect. “For the ground floor, we opted for a coating in fired blue bluestone, a good match with the small grey speckles, the white mass of the Nayla type and the terrace floors in a grey tone,” says Deconinck about the choice for the DKTN colour “Nayla” (white speckled).

“Thanks to its properties, DKTN delivers high-quality, technical performance compared to other existing surfaces: highly scratch-resistant, frost-resistant and thaw-resistant, and resistant to salty air and UV rays. Colour stability, dimensional stability and pressure resistance are high. With a fire reaction class A2, s1-d0, DKTN can even be used for tall buildings,” says Stephanie Bevernagie of Cosentino.
