Key Specifications
Product Overview
Traditional saturated organic asphalt roofing felt, commonly known as tar paper or linoleum underlayment. It is manufactured by fully saturating a thick, absorbent organic fiber base paper with premium molten petroleum asphalt. The surface is coated with talcum powder or fine sand to prevent sticking during unrolling, making it a reliable sloped roofing underlay.

- High Saturation: High asphalt saturation and oil absorption capacity for durable water resistance.
- Temporary Protection: Provides temporary waterproofing protection before the main roofing is installed.
- Easy Handling: Easy to handle, cut, and mechanically fasten onto plywood or wooden decks.
- Vapor Permeability: Allows vapor to pass while maintaining a secure liquid water barrier.
