B41 gets new-generation roof

Building 41’s 5,000 sq. m of roofing was totally replaced over the course of last year. The rainy summer didn’t delay the huge job and, for B41’s cleanrooms just below, it was business as usual.

The former 25-year-old rockwool and asphalt roofing is now just a memory. The new roof boasts a new-generation material similar to a swimming pool liner that will stand up to rain and snow for a long time to come.

And that’s not all—the new roof’s gentle pitch will keep water flowing off of it, while protective panels will prevent damage from mobile snow removal equipment. The roof has already seen ample rain and snow this year, without a leak in sight!
