LaSalle Bristol Butyl Tape: Purpose-Built Sealing for RVs and Manufactured Housing
When it comes to keeping moisture out of your RV or manufactured home, the sealant tape you choose matters as much as the installation itself. LaSalle Bristol (Bristol Products) brings decades of expertise in the RV and factory-built housing industries directly to their line of butyl tape products — and the results speak for themselves.
Backed by over 70 years of experience serving the recreation vehicle and manufactured housing sectors, LaSalle Bristol is a wholesale distributor and manufacturer headquartered in Elkhart, Indiana — the heart of North America's RV industry. That deep-rooted industry knowledge translates into butyl tape products that are designed around real-world installation challenges, not just laboratory specs.
XTRM Polysul-Grip Butyl Tape
LaSalle Bristol's butyl tape line is built around their XTRM Polysul-Grip formula — a specialized adhesive/sealant tape engineered specifically to complement RV roofing membranes and sealing applications. Two primary configurations are available: a narrower 3/4" x 60' roll suited for tighter seams and screw-hole sealing, and a wider 1-1/2" x 45' roll designed for broader joints, awning rail installations, and roof membrane overlaps.
What sets the XTRM formula apart from generic butyl tapes is its resilience under real travel conditions. It will not crack under the stresses of road vibration and temperature fluctuations — a critical quality for any sealant expected to hold up mile after mile. It provides excellent adhesion to both porous and non-porous materials, and that adhesion actually improves with age.
Where LaSalle Bristol Butyl Tape Gets the Job Done
The versatility of this tape makes it a go-to solution across a wide range of RV maintenance and installation tasks:
- Filling gaps around vents, windows, and doors to provide a weatherproof seal that safeguards against moisture intrusion.
- Sealing screw holes when mounting roof vents, awning rails, and solar panels — the tape goes between the wall and the mounting bracket, and the screw pulls the butyl into the hole to help seal it from water penetration.
- Sealing uniquely shaped joints where standard caulk or rigid tape would struggle to conform.
- Use alongside self-leveling lap sealant for a complete, multi-layer weatherproofing system on rubber roofs.
Why the Continuous-Roll Format Matters
LaSalle Bristol butyl tape is supplied in a continuous roll format, which offers a practical installation advantage: installers can work fast and be virtually assured that there are no skips or runs — eliminating the gaps that cause leaks down the road. It installs quickly, without gaps.
The tape is compatible with a wide range of substrates, including rubber roofing membranes, metal, wood, glass, concrete, and plastic — making it equally useful for manufactured home builders and RV owners tackling DIY repairs.
Part of a Trusted Supply Ecosystem
LaSalle Bristol doesn't just manufacture butyl tape in isolation. In addition to distributing leading national brands, LaSalle Bristol manufactures its own plumbing, air systems, and decorative products, offering RV and manufactured housing builders a uniquely integrated supply partner. That means the butyl tape is engineered to work in concert with other LaSalle Bristol sealing and roofing products — giving builders and repair technicians a cohesive, compatible system rather than a patchwork of unrelated components.
Whether you're resealing a roof vent, mounting an awning rail, or doing a full membrane roof repair, LaSalle Bristol butyl tape delivers the durable, flexible seal that mobile and stationary structures demand.
