Paradiene 20/30 SBS-Modified Bitumen Membrane Systems

There are certain physical properties that high-quality SBS-modified bitumen membrane systems (e.g., Siplast Paradiene 20/30 system) have that help enable it to maintain performance over decades of service on a roof. It starts with the asphalt blend, which drives some of the physical requirements for long term performance. The reinforcement combined with the upper and lower layers of SBS-modified bitumen determine the primary physical properties and performance characteristics of the sheet. In other words, what Siplast does prior to and during manufacture of the Paradiene 20 and Paradiene 30 sheets is a huge part of what leads to the roof's potential long service life. Of course, the installation, the design, and maintenance of the roof also play a big role. Assuming that those aspects are handled properly, it is the SBS-modified bitumen formulation combined with the reinforcement (i.e., the roof membrane) that composes the backbone of the system that sets up the installed roofing system for long-term success.

Waterproofing Membrane Types, Applications, and Best Practices

Waterproofing membranes help protect structures from water damage by creating a barrier against water infiltration. This makes them ideal for applications that involve higher levels of moisture due to environmental conditions or the presence of water, such as foundations, parking garages, and green roofs.

What to Know About Building Enclosure Design

Similar to how a winter jacket protects you from the elements, a building envelope protects the contents of a building throughout its lifespan. A successful building enclosure design separates the interior of the building from the exterior while controlling the exchange of heat, air, and moisture between the two. It can extend the life of building components and help keep occupants comfortable year-round.

Stormwater Management for Resilient Design

Urban flooding has become an increasingly frequent occurrence in recent years, prompting the need for effective stormwater management at commercial properties. In addition to the damage floods can cause, uncontrolled stormwater flow creates potential risks to individuals' health and well-being. If debris, pollutants, and trash are allowed to flow into drainage and sewer systems, this could ultimately end up contaminating local drinking water.

PVC vs. TPO: A Straightforward Guide for New Roof Designers

If you are just getting started in the roofing industry, chances are you have already come across the term single-ply roofing. It is a popular roof system used on commercial and industrial buildings, especially low-slope rooftops, and offers a solid balance of durability, ease of installation, and energy efficiency.

Why Substrate Imperfections Matter in Roof Design

Specifiers and designers often focus on the visible components of a roof system: the membrane, the flashing, the aesthetic. However, the often-overlooked substrate—the foundation upon which the entire system rests—plays a profoundly critical role in long-term performance and durability. A long-term roofing system can only be achieved with a sound and suitable substrate.

The Best Waterproofing for Roof Penetrations, Transitions, and Detailing Challenges

Just as the roof provides a protective barrier against the elements for a building interior, sealants are essential for maintaining the integrity of the roof itself. By sealing the flashing around breaks and gaps caused by pipes and other penetrations, sealants perform a vital function in the execution of the best waterproofing for roof systems. Sealants can also be used to fill holes around solar panel fasteners or adhere layers of roofing materials as well as repairing leaks and chimney damage caused by the environment.

Understanding Diagonal Wrinkling in Roof Membrane Base Flashing

We've all seen it: diagonal wrinkling, sometimes called "racking," appearing in membrane base flashings along parapet walls. While seemingly minor, this condition can compromise the long-term performance and watertight integrity of a roof membrane system.

Factors to Consider When Choosing Below-Grade Waterproofing Systems

Hidden from view once buried underground, below-grade waterproofing systems are often overlooked in construction. Once it's out of sight, it's out of mind. However, taking the appropriate measures to select the right moisture control system is essential to a building's structural integrity. Getting this detail right the first time around can help minimize the risk of problems and expensive repairs over the long term.

Is Pre-Applied Waterproofing Right for Your Project Needs?

Whether a building construction project is a new build or involves adaptive reuse of an existing structure, the foundation rarely generates the attention of curved glass facades or imposing columns. However, without a sturdy foundation, the most impressive new building or renovated structure is vulnerable to failures over time, such as wall cracking and other structural damage.

Sustainable Roof-to-Wall Transitions: Optimizing Performance and Efficiency

The building enclosure is a crucial set of assemblies and components that separate the interior conditioned space from the elements outside. The building enclosure covers the entire exterior surface area and therefore has a critical role in controlling heat loss and gain, air infiltration, and moisture. Together, these attributes can significantly affect the energy-efficiency of commercial buildings.

The Nuts and Bolts of Resilient and Sustainable Roofs

Resiliency. Sustainability. These terms get tossed around a lot in the industry, especially when it comes to defining sustainable roofs. These terms, to most of us, are more nebulous than practical when it comes to buildings and roofing. Of course, dictionary definitions trend to the common uses of the words. Simply put, resilience is the ability to bounce back, and sustainability is the ability to continue over time.

LCCA Techniques for Roofs on Complex Building Types

One of the critical components of a building, both in terms of design and cost, is its roofing system. Building owners and consultants face the challenge of accurately predicting and managing a facility's long-term costs; life cycle cost analysis (LCCA) can help. Initial capital expenditures are often the focus during the design and construction phases. However, the ongoing costs associated with a building's energy use, as well as roof maintenance and eventual replacement, can make up a significant portion of a roof's total expenses over the service life of a building and its roof.
