# Built for the Toughest Weather Conditions - Palisade® Butyl-HT PLUS

![Butyl-Roofing-Underlayment](https://blog.ecp.itape.com/hubfs/Butyl-Roofing-Underlayment.jpg)

When it comes to [protecting a roof](https://learn.itape.com/experts-guide-to-roof-underlayment?hsLang=en), the most common failures don’t happen in wide-open field areas — they happen at fasteners, seams, transitions, and edges. That’s where underlayment performance truly matters. [Palisade® Butyl-HT PLUS](https://ecp.itape.com/product/palisade-butyl-ht-plus/) is engineered to address these vulnerabilities head-on, delivering long-term, high-performance protection for today’s demanding roofing systems. 

Designed as a non-asphaltic, 100% pure butyl underlayment, Palisade® Butyl-HT PLUS combines aggressive adhesion, extreme temperature stability, and long-lasting elasticity to outperform traditional felt and many asphalt-based membranes. 

### Ultimate Self-Healing at Fastener Penetrations 

Fastener penetrations are the number-one source of roof leaks. Thanks to the naturally viscous properties of butyl rubber, Palisade® Butyl-HT PLUS self-seals tightly around nails and screws, forming a watertight gasket at every penetration. This self-healing behavior dramatically reduces the risk of water infiltration over time — even as the roof expands and contracts with temperature changes. 

### Aggressive Adhesion You Can Trust![Palisade-Butyl-HT-Plus](https://blog.ecp.itape.com/hs-fs/hubfs/Palisade-Butyl-HT-Plus.png?width=350&height=241&name=Palisade-Butyl-HT-Plus.png)

Palisade® Butyl-HT PLUS is engineered for exceptional adhesion to clean, dry surfaces, including plywood, metal, concrete, and rigid insulation. Its strong lap and deck adhesion helps maintain a continuous water barrier across the roof surface, even in colder installation conditions down to 10°F (-12°C). This dependable bond ensures the membrane stays exactly where it’s installed — no slipping, lifting, or loss of seal. 

### Near-Impermeable Protection Against Water 

With an ultra-low permeability rating of 0.01 perms, Palisade® Butyl-HT PLUS creates a near-impermeable barrier against water vapor transmission. This makes it especially effective in defending against ice dams, wind-driven rain, and prolonged moisture exposure. Unlike some underlayments that degrade when exposed to standing water, butyl maintains its sealing performance even under continuous moisture pressure.

### High-Temperature Performance for Metal Roofing 

Metal roofs are known for extreme surface temperatures, and not all underlayments are up to the task. Palisade® Butyl-HT PLUS is rated for temperatures up to 265°F (130°C), making it ideal for metal roofing systems where asphalt-based products may soften, flow, or break down. Butyl’s inherent heat stability ensures the membrane maintains its integrity without melting or oxidizing over time.![Palisade Butyl Extreme Weather](https://blog.ecp.itape.com/hs-fs/hubfs/Palisade%20Butyl%20Extreme%20Weather.jpg?width=350&height=241&name=Palisade%20Butyl%20Extreme%20Weather.jpg)

Stability in Extreme Weather — Hot or Cold

From freezing winters to scorching summers, [Palisade® Butyl-HT PLUS remains flexible in cold climates and stable in high heat](https://blog.ecp.itape.com/why-palisade-butyl-ht-plus-is-the-top-choice-for-self-adhered-roof-underlayment?hsLang=en). It passes low-temperature flexibility testing down to -30°F (-34°C) without cracking, while its non-flowing composition prevents deformation in hot conditions. This wide temperature performance makes it a reliable choice across diverse climate zones.

UV Resistance That Supports Jobsite Efficiency

Roofing projects don’t always move on a perfect timeline. Palisade® Butyl-HT PLUS offers UV exposure resistance for up to six months, allowing for extended installation windows without compromising performance. This added flexibility helps crews stay productive while maintaining long-term protection for the structure below. 

Permanently Elastic for a Longer Roof Life

Unlike materials that harden and become brittle over time, butyl rubber remains permanently elastic. Palisade® Butyl-HT PLUS won’t crack, shrink, or lose adhesion as it ages. Because it does not oxidize like many asphalt-based products, its performance remains consistent for decades — contributing to a service life that can exceed 60 years under proper conditions. 

![Stronghold-Circle2](https://blog.ecp.itape.com/hs-fs/hubfs/Stronghold-Circle2.png?width=200&height=200&name=Stronghold-Circle2.png)Designed for Compatibility and Safety

Palisade® Butyl-HT PLUS is compatible with a wide range of roofing systems, including metal, asphalt shingles, synthetic shingles, slate, tile, primed cedar shakes, EPDM, and TPO. It also features [Stronghold® Skid Resistant Technology](https://ecp.itape.com/roof-underlayment/) for improved traction and safer rooftop installation, along with KOOL BLUE™ color technology to reduce glare and surface heat. 

A Smarter Investment in Long-Term Protection

When roof performance matters for decades — not just years — butyl makes the difference. Palisade® Butyl-HT PLUS delivers unmatched sealing power, extreme weather resistance, and long-term durability that outlasts traditional felt and many self-adhered alternatives.
