FT Synthetics Platinum HT-B High Temperature Self-Adhered Ice & Water Membrane, 36 in. x 67 ft Roll
FT Synthetics Platinum HT-B is a high-temperature self-adhered waterproofing ice and water membrane supplied as a 36 in. x 67 ft roll. Its 100% butyl adhesive bonds strongly to plywood or OSB roof decks and installs at temperatures as low as 32°F (0°C) and rising. Each roll is the sell unit.
Key Features:
- High temperature rated: Platinum HT-B is a high-temperature self-adhered waterproofing membrane.
- 100% butyl adhesive: The butyl adhesive provides an ultimate bond to plywood or OSB roof decks.
- Strong deck adhesion: Deck adhesion is significantly stronger than standard modified bitumen products.
- Cold-weather install: Installs at extremely low temperatures, from 32°F (0°C) and rising.
- Waterproof barrier: Self-adhered membrane protects eaves, valleys and vulnerable roof areas from ice and water.
- Standard roll size: Supplied in a 36 in. x 67 ft roll for easy handling and planning.

Expert Verdict — Reviewed by the SuperArbor Pro Desk
Platinum HT-B's 100% butyl adhesive and low 32°F install threshold make it a strong pick for early-spring and cold-climate jobs where modified bitumen underlayments struggle. Roll it out over clean, dry deck, roll the laps firmly, and use it generously at eaves, valleys, penetrations and chimneys. Its high-temperature formulation suits dark roofs and metal coverings that run hot in summer.
Self-adhered membranes are slippery, especially with frost or dust; wear fall protection and non-slip footwear and keep the deck clean during installation.
Protect vulnerable roof areas with FT Synthetics Platinum HT-B ice and water membrane rolls.
