GDL has revamped its Intelivent natural-ventilation web site to replicate its recently launched brochure. The interactive style provides product information and case studies that demonstrate where GDL’s natural-ventilation systems would simplify specification processes for customers.
The company has significantly extended its product range to offer more choice of wind-driven and solar-powered ventilation. There is also the option of incorporating natural lighting in all building types. GDL offers a full turnkey package of design, manufacture and installation.
