RENOLIT have provided their RENOLIT ALKORBRIGHT membrane for the waterproofing works on the roof top of the Royal Museum of Fine Arts in Antwerp, Belgium.
The membrane was cut to size to be installed around 198 different-sized triangular skylights.
In addition to being of great aesthetic impact, the 198 triangular roof skylights are built to allow the northern light to enter the museum's rooms.
In fact, the north facing windows allow indirect lighting, avoiding any compromise between visual experience and conservation of the art on display.
The system is entirely white, flexible and with a SRI equal to 115.
These characteristics allow the sun’s rays to be reflected to the maximum, an effective way of improving the quantity of indirect light coming through the windows and provide additional internal lighting.
The membrane also helps to reduce excessive heat in the building during the summer and, also reducing energy consumption due to air conditioning.
198 triangular wooden constructions were covered with RENOLIT ALKORPLUS81002, a self-adhesive bituminous vapour control layer.
To assure a perfectly waterproof and neat finish RENOLIT ALKORPLUS metal sheet profiles were secured to the edges.
Lastly, each triangle was covered with the RENOLIT ALKORBRIGHT membrane. 1,665 m2 of membrane cut to size into different small sections, to perfectly fit the skylights, which are also of different sizes.
