Why are Shanghai's luxury mansions obsessed with this "breathable" wood?

When Mr. Zhang first entered his new office in North Bund, he was instantly shocked by the criss - cross wooden structures overhead - these beams and columns exuding the fragrance of pine were actually made of imported cross - laminated timber. This material, known as the "Lego of the wooden construction industry," is quietly revolutionizing the high - end construction field in Shanghai.

Unlike traditional solid wood, cross - laminated timber (CLT) is made by gluing multiple layers of wood vertically and alternately. This unique structure gives it three major advantages:

• Strength comparable to concrete: Laboratory data shows that the compressive strength of a 30 - cm - thick CLT board reaches 35MPa
• Weight is only 1/5 of that of steel: Greatly reduces the building foundation load, especially suitable for Shanghai's soft soil foundation
• High degree of prefabrication: Error controlled within 0.1mm, and on - site assembly is like building blocks

Ms. Li recently found when selecting materials for a cultural and creative project in Jing'an that although there are domestic CLT manufacturers, imported products have advantages in:

• Environmental certification: All hold FSC/PEFC forest sustainability certifications
• Fire - proof performance: Passed the EU EN16351 fire - resistance test
• Size stability: Using slow - growing spruce from the Nordic forests, with a moisture content controlled at ±2%

As a professional import agent, we have found that customers often fall into three misunderstandings:

• Believing that the delivery cycle of imported CLT is long (in fact, European factories have a 3 - month inventory of standard products)
• Worrying that customs clearance is complicated (pre - preparing the EN13986 certification in advance can speed up the process by 40%)
• Underestimating transportation costs (scientific container loading can save 15% of the freight)

In a super - high - rise project in Lujiazui, CLT components embedded with NFC chips have turned every wooden block into a traceable "digital twin." When environmentally friendly building materials meet Internet of Things technology, perhaps soon we will be able to see "breathable" intelligent wooden - structure buildings.

Are you also considering using this material? Welcome to share your insights on modern wooden - structure buildings. After all, when Notre - Dame de Paris chose CLT to rebuild its spire, the renaissance of wood had already arrived.
