Loire De Trelaze Arena

Trelaze arena made with a vertical skin in Frequency profile and pre-painted ultra matt black blackberry.
The Arena Loire in Trélazé required very high performances in terms of thermal and acoustic insulation. The architect Bernard Chinours and his teams were led to design a system using double and triple skin complexes, including the CIN 325 GlobalRoof CIN 325 is a roof waterproofing complex that guarantees exceptional soundproofing while offering an aesthetic advantage due to the absence of visible fastening of the insulation in the underside. It is composed of perforated Hacierco roofing trays (pre-painted galvanized steel profile) and Hacierco waterproofing supports. This complete system makes it possible to achieve high sound attenuation levels and therefore not to disturb the neighbourhood with noise pollution during sports or entertainment events.

Sound attenuation index: Rw (C ; Ctr) = 55 (-2 ; 8) dB
Sound absorption coefficient: Alpha w = 0.90
Heat transfer coefficient per unit area Up = 0.20 w/m2K
