Ensure Your Membrane Splices Are Up to Industry Standards
February 5, 2019
Installing a water-tight single-ply roofing system is necessary to ensure a successful, long-lasting, and effective roofing experience. One of the biggest challenges in the application of these systems is ensuring that all seams, curbs, and miscellaneous items are flashed-in per industry standards. Of those items, seams are an integral part of the system and their central purpose is to tie-in one sheet of membrane to another. Proper mating of both sheets at this connection point not only creates one uniform system, but also serves as the first line of defense to moisture infiltration.

Many warranty claims can be attributed to this aspect of a single-ply system and is a very common reason for roof failure. Carlisle SynTec’s Sure-Seal® EPDM Kleen Non-Reinforced roofing membrane makes installing seams easier and ensures seam integrity in the long term – resulting in less call-backs, and a better relationship between the applicator and customer.

There are many benefits to installing seams on Sure-Seal EPDM Kleen membranes:

  1. The membrane is pre-cleaned to remove mica dust, therefore eliminating the need to clean the seam areas with Weathered Membrane Cleaner prior to the application of primer. 
  2. Pre-cleaned EPDM allows primer to be applied with a roller. 
  3. Three-inch and six-inch Factory-Applied Tape (FAT) is available on all Sure-Seal Kleen membranes up to 10-feet wide which greatly reduces the time needed to complete seams. 

The above steps will improve productivity in the field, create less jobsite waste, and result in a quality-controlled installation. Please reach out to your local Carlisle Representative for more information about our Sure-Seal EPDM Kleen products.

Special Color TPO Accessories

As the demand for different colored roof membranes has grown, Carlisle introduced its TPO Color Palette with five new colors. In addition to standard white, gray, and tan, Carlisle’s TPO Color Palette now features Rock Brown, Slate Gray, Terra Cotta, Patina Green, and Medium Bronze. Projects that use special color membrane from the TPO Color Palette usually need flashings and accessories in the same color. Here, contractors have two choices, one of which is painting standard accessories to match the membrane. However, this is a great opportunity to use Carlisle’s custom TPO accessory program and avoid painting altogether. All Carlisle custom accessories are available in the five TPO Color Palette colors, as well as white, tan, and gray. Whether it’s a simple split pipe seal or a complex prefabricated curb wrap, Carlisle can make it in all eight TPO colors and get it to the job quickly. In addition to being available in eight colors, here are some other great advantages to using custom flashings from Carlisle: • Save time vs. field fabrication: Trying to field-fabricate flashings can be time-consuming work, even for the most skilled and experienced roofers. Using prefabricated flashings saves time. • No need for paint: There’s no need to prime and paint the accessories to match the membrane; just install and go. • Speed: Custom accessories can be fabricated and shipped within days, not weeks. • Quality: All of Carlisle’s custom TPO accessories carry the Certified Fabricated Accessory (CFA) stamp of approval, indicating they are eligible for coverage as part of the Carlisle Total Roofing System Warranty. Next time you have a project using Carlisle’s TPO Color Palette TPO, consider using custom accessories to make the job faster and easier to install.

Solving Unique Challenges with a Hybrid Approach to Insulation

One of the simplest ways to meet building codes requirements in construction is through the effective use of insulation. There are several types of rooftop insulations available in the marketplace, but two of the most commonly accepted in commercial roofing applications are polyisocyanurate (polyiso) and expanded polystyrene (EPS). Polyiso is a lightweight and cost-effective, closed-cell, rigid foam board insulation that provides energy-efficient solutions for buildings in any region and climate, as well as outstanding return on investment and significant energy savings. EPS is a closed-cell, rigid foam insulation manufactured using expandable polystyrene. It is block-molded for most construction applications and is highly customizable, enabling thicknesses up to 40 inches in a single board. EPS is versatile and durable and can provide significant cost and labor advantages. Both polyiso and EPS provide great benefits and R-value in roof construction projects. However, projects often arise when a hybrid solution to insulation may be the most practical. A hybrid polyiso/EPS solution can help you edge out the competition in a number of scenarios. New Construction with Concrete Decks  A recent innovation introduced by Carlisle is ChannelDry® EPS Insulation. ChannelDry is ideal for new construction projects with structural concrete, lightweight structural concrete, and lightweight insulating concrete roof decks. Using ChannelDry in conjunction with one-way and two-way relief vents allows the installation of the roof system to begin upon structural cure of concrete (typically around 28 days). ChannelDry is compatible with ballasted, mechanically fastened, induction welded, and adhered single-ply roofing systems. The use of ChannelDry creates a problem-solving solution for new construction involving concrete decks, enabling construction to commence immediately upon structural cure. Standing Seam Metal Roofs  With square-, taper-, and profile-cut flute-fill products in custom shapes and sizes, a solution is available for all metal retrofit roofs. Combining EPS to fill the metal roof flutes with a subsequent layer of insulation or coverboard can create an ideal foundation for a retrofit roof. Click here to hear a contractor describe the benefits of this system from a project in Windsor, Ontario, Canada. Tapered Roof Design  A tapered roof is another ideal candidate for a hybrid approach to save time and money. With thicknesses up to 40" and virtually any slope available in a single board, a base layer of tapered EPS insulation can save nearly 30% in product cost alone, with additional savings on installation time when combined with polyiso. Combining polyiso and EPS in commercial roofing applications is an effective solution that can often save you money and labor on a project. Contact your local Carlisle representative to learn more.

Roofing with Resilience: A Review of 30-Year EPDM Enhancements

The history of EPDM roofing runs deep. With over 50 years on the market and billions of square feet produced and installed, Carlisle SynTec’s EPDM has a proven track record as one of the most resilient membranes in the single-ply roofing industry today. As time goes on and the construction industry evolves, more sustainable structures are becoming the norm. Building codes are increasingly robust and are placing a greater emphasis on protecting your building from Mother Nature’s wrath. Your roof system plays a huge part in achieving compliance and serves as the first line of defense against hail, wind, and other damaging elements. This is where EPDM’s sustainability and durability come into to play. Sustainability and resiliency are some of the strongest attributes of Carlisle’s EPDM membranes, and EPDM’s durability allows us to offer a high-end, 30-year Total System Warranty that guarantees long-term performance. Below are the enhancements that Carlisle SynTec requires when upgrading to a 30-year EPDM system: 30-Year EPDM Enhancements The Membrane: The thicker and more durable 90-mil EPDM, 75-mil reinforced EPDM, or 145-mil FleeceBACK® EPDM are required; fully adhered, mechanically fastened, or ballasted designs are available. The thicker membranes will provide greater long-term performance and superior resistance to weathering. Please note, 45-mil and 60-mil membranes are not eligible for 30-year Total System Warranties. The Splices: Membrane splices are one of most important parts of any roofing system and utilizing our Factory-Applied Tape™ means more watertight seams and fewer warranty claims. On a 30-year EPDM system, Carlisle requires membrane with 6”-wide Factory-Applied Tape or 6” SecurTAPE™ to be installed at all seams and end laps. The 6”-wide tape has greater peel and sheer strength and results in a stronger bond. Please note, 3” factory-applied or hand-applied tape on 30-year warranties must be stripped in with Pressure-Sensitive Cured Cover Strip. The Flashing Details: In addition to seams, flashing details are critical to preventing issues where rooftop penetrations are tied in to the field membrane. On 30-year EPDM systems, Carlisle requires specific details to be double-wrapped or covered with two layers of flashing. Below is a list of these details: Key U = Universal (applies to all 30-year systems) A = Adhered Systems Only B = Ballasted Systems Only MF = Mechanically Fastened Systems Only U-2D SecurTAPE Splice Intersection (25-/30-Year Warranties) U-8A.1 Pre-Molded Pressure-Sensitive Pipe Seal with 90-mil Membrane or 25-/30-Year Warranties U-8B.1 Field Fabricated Pipe/Structural Steel Tube Flashing for 25-/30-Year Warranties U-15D.1 Inside Corner Flashing for Projects with 90-mil Membrane or 25-/30-Year Warranties U-15H Outside Corner Flashing for Projects with 90-mil Membrane or 25-/30-Year Warranties A-2 Membrane Splice (25-/30-Year Warranties) B-2 Membrane Splice (25-/30-Year Warranties) MF-2D Membrane Splice (25-/30-Year Warranties) MF-2E SecurTAPE Splice Intersection (25-/30-Year Warranties) ***Please speak with a Carlisle SynTec Design Analyst about additional 30-year requirements in regards to adhesives, coverboards, insulation, fastening density, perimeter securement, and metal edging.***     Ryan Ferguson     EPDM Product Specialist     Product Marketing     [email protected]
