For over half a century, Siplast has been a benchmark for innovation in the roofing industry. Architects, contractors, and building owners have long trusted our high-performance roofing and waterproofing systems to protect their most valuable assets.

Now, we are taking the next step in commercial building protection. By leveraging decades of manufacturing excellence, Siplast is proud to introduce WALLcontrol™—a premium portfolio of Air and Water Barriers (AWBs), polyiso insulation, and wall flashings.

Whether you are a long-time partner or a new customer looking for the "best" in building enclosure technology, the expansion of the Siplast portfolio means you can now secure the entire building envelope under one trusted name.

Why Choose Siplast for Your Next New Construction Project?

In the world of new construction, timing and integration are everything. Getting in early with the right specified products can mean the difference between a seamless build and a logistical nightmare.

By choosing Siplast for both your roof and wall systems, you aren't just buying products; you are investing in a single-source solution. This holistic approach ensures that the critical transitions between the roof and the wall—often the most vulnerable points for leaks and air infiltration—are engineered to work together perfectly.

Overcoming the Resistance to "New"

We understand that in the construction industry, "new" can sometimes feel risky. However, the WALLcontrol™ suite isn't just a new offering; it is a natural evolution of Siplast’s proven technology. We have applied the same manufacturing rigor and field-tested quality that made our roofing systems legendary to our wall components.

When you specify WALLcontrol™, you’re getting:

  • Decades of Expertise: Built on the foundation of Siplast’s waterproofing legacy.

  • Design Guidance: Support from regional specialists who understand the unique climate challenges of the Northeast (NE) and beyond.

  • Field Tech Services: On-site partnership to ensure installation excellence.

The WALLcontrol™ Portfolio: Premium Solutions for Every Layer

Our "good, better, best" philosophy ensures that we provide the highest tier of protection available in the market. WALLcontrol™ products create a continuous air and water barrier, offering exceptional temperature stability and Class A fire ratings.

1. High-Performance AWBs

Minimize unwanted air and water movement with membranes engineered for high heat and UV exposure.

  • Monolith VP Adhered: A primerless, vapor-permeable, self-adhered membrane that creates a solid monolithic sheet.

  • Modified Silicone (STPE) VP Liquid: A moisture-cure, liquid-applied AWB for seamless application.

  • Reinforced Aluminum Butyl-Adhered: A non-vapor-permeable option designed for high-tensile strength and extreme temperature stability.

2. Advanced Polyiso Insulation

Maximize energy savings without adding bulk. Our polyiso solutions feature a high R-value per inch and are available in:

  • Glass-Faced: Durable coated glass facers for robust performance.

  • Foil-Faced: Ideal for those requiring an air barrier that meets stringent CAN/ULC standards.

3. Precision Flashings and Accessories

The details make the building. Our stainless steel and aluminum butyl-adhered flashings offer primerless application, saving time and labor on the job site while providing robust resistance to punctures and tears.

The Power of Single-Source Warranties

One of the greatest points of resistance in commercial construction is "finger-pointing" between different manufacturers when a leak or performance issue occurs.

Siplast eliminates that friction.

Because WALLcontrol™ products integrate seamlessly with Siplast roofing systems, you can enjoy the convenience of a single-source warranty. This means:

  • One point of contact for enclosure coverage.

  • Streamlined administrative processes.

  • Peace of mind knowing that every component of your building’s exterior is backed by one trusted manufacturing partner.

Surround Yourself with Quality from the Beginning

From the foundation to the parapet, and now across the entire vertical wall, Siplast is your partner in building enclosure integrity. By integrating your systems under one roof (and one wall), you optimize performance, simplify your supply chain, and ensure your project is built to last.

Don't wait until the walls are up to think about protection. Get in early for your next project and experience the synergy of Siplast.
