The first port of call when designing with GIB Weatherline® Rigid Air Barrier Systems is the GIB Weatherline® Design and Construction manual, but sometimes additional specification material may have been developed which might be useful for a smaller number of projects and not warrant inclusion into main manual.

Winstone Wallboards keeps this more ‘niche’ material in the GIB Weatherline® Online Technical Supplement. So if you can’t find what you're looking for in the GIB Weatherline® Manual try the online supplement in the Technical Literature tab.

The GIB Weatherline® Supplement currently includes:

• New GIB Weatherline® 120min FRR two way fire systems.
• New GIB Weatherline® 30min FRR one way fire systems.
• GIB Weatherline® and flexible wall underlay option.
• GIB Weatherline® steel frame with thermal break specification.
