Notes for your next specification.
Every note is written for project use: what to specify, what to check, and which details fail first on site.
Specifying FRP daylight panels for humid, high-UV climates
Resin type, UV stabilisation and fixing detail decide whether a daylight roof stays clear through a decade of sun, rain and thermal cycling.

Ridge ventilation: sizing airflow for large logistics warehouses
Throat area, airflow and wind pressure decide whether a continuous ridge ventilator performs as designed — or becomes a leak path.

Resin selection for coastal steel buildings: beyond “corrosion resistant”
Salt spray, humidity and UV combine differently on a coast. The right FRP specification depends on the exposure zone, not a single product label.

VIVON expands continuous lamination capacity for FRP panels
A second continuous lamination line is now in production, improving lead times for large daylight and corrosion-resistant panel orders.

Fireproof coating: what R30, R60 and R90 actually require
The fire rating is only one input. Section factor, steel type and topcoat compatibility determine the dry film thickness and the evidence to request.

Cold-chain envelope detailing: where thermal bridges hide
Insulated panels perform at their stated U-value only when joints, penetrations and structural connections are detailed as carefully as the panel.
