Icopal Anderson Torch on VBL Venting Base Layer

Icopal Anderson Torch on VBL Venting Base Layer is a bitumen roofing membrane manufactured on a bonded fibreglass carrier perforated with 25 mm holes staggered at 75 mm centres. It is a bitumen membrane intended as a perforated preparation/base layer to create a partial bond to the substrate for the underlay within a high-performance bituminous built-up roofing system. The membrane is laid loose.

Frequently Asked Questions (FAQs)

Do you torch a Vented Base Layer?

No, a vented base layer (VBL) is not typically torch-applied. VBL is generally used as a base or additional layer beneath the torch-on roofing system to provide added protection and insulation.

Do you need a Vented Base Layer for the torch on felt?

Yes, a Vented Base Layer is typically required for torch-on-felt roofing systems. The underlay provides an additional layer of protection against moisture, improves thermal insulation, and helps to create a smooth surface for the torch-on felt to be applied onto.

Do you nail or staple a Vented Base Layer?

Roofing felt is typically fastened using nails rather than staples. Pins provide a more secure and durable attachment to the roof, ensuring the felt remains in place.
