Light Transmission

The grey pigmentation in Iplex Pro-Fit® pipe prevents the transmission of light that would otherwise promote algae growth. Polybutylene should not however be stored or installed in direct sunlight

Fire Protection

Polybutylene will burn when exposed to an open flame and in fact continue to burn when the source of fire is removed. The by-products of polybutylene combustion are carbon monoxide, carbon dioxide and water These same combustion products are generated when any organic material burns.

Where polybutylene pipe is installed and penetrates fire resistant construction, the fire resistant integrity of the construction must be retained.

This can commonly be achieved through the use of fire-stop collars but refer to the local building code.
