Advantages to using Tapered InsulFoam roofing insulation:

  • Labor Savings:  there are no complicated filler panel systems.  Tapered InsulFoam can be installed in a single layer for thicknesses up to 40″, and is significantly more cost-effective than extruded polystyrene, perlite and isocyanurate tapered systems.
  • Promoted Positive Drainage:  Tapered InsulFoam is the ideal insulation for both new construction and re-roofing projects in which positive slope is desired or ponded water is a concern
  • Environmentally Friendly:  contains no formaldehyde or ozone-depleting HCFCs, contains recycled material, and is 100% recyclable if ever removed or replaced.
  • Stable R-Value:  designers are well served knowing the product’s thermal properties will remain stable over its entire service life.  There is no thermal drift, so the product is eligible for an Insulfoam 20-year thermal performance warranty.

Energy Efficient Construction at World of Concrete

EVENT:  World of Concrete, Las Vegas   |   DATE:  February 5-8th   |   BOOTH:  N2915


The future of architecture and construction is not only going to expand and grow at a rapid pace this New Year, but it is also becoming one of the r-tech_blog copybest industries in regards to saving the environment. When it comes to ultimate respectability in the industry, two names have come together to form one truly amazing ‘gift’ for all the building-owners and contractors out there. The name, Insulfoam, is synonymous with the creation of quality polystyrene-based engineered insulation products that have become even better than before. In addition,Carlisle Construction Materials has been known in all areas of architecture and construction for single-ply roof systems and waterproofing products that are unmatched in quality, durability, and savings. With Insulfoam, the largest manufacturer of expanded polystyrene in all of North America, being a part of Carlisle Construction Materials for several years now, these two powerhouses have shown the rest of the industry that they are not only still among the most respected names in construction, but are also constantly looking out for everyone from architects to building owners to contractors. With this ‘team,’ everyone has the ability to purchase and utilize energy-efficient construction products that are a ‘must-have’ in this ‘greener’ world. Insulfoam’s products insulate buildings, from the foundation to the roof and everything in-between. Versatility is a key word when it comes to these products. Not to mention the product line is 100% recyclable. Being leaders and visionaries when it comes to new product development, the latest in technology, and code approvals, the brands of InsulFoam® and R-Tech® also contribute immensely toward LEED® credit requirements, which is one of the biggest and most important issues to address nowadays. Insulfoam products, which have warranted long-term stable R-values with no thermal loss, are built upon sustainable manufacturing practices. Dye-free, free of formaldehyde and HCFCs, no toxic chemicals or heavy metals are leeched, and prevention of mold or mildew growth, are just a few of the benefits that come with these products. Offered under the InsulFoam® and R-Tech® brands, Insulfoam’sexpanded polystyrene (EPS) products for under-slab and below-grade applications insulate foundation walls, protect water and/or damp proofing, and can be used during backfilling in both commercial and residential projects.

roofing copyStudies have shown that R-Tech® below-grade insulations have some of the lowest levels of long-term water retention among below-grade insulation products. Combined with high compressive strength and long-term stable R-values, these properties make Insulfoam’s products among the most efficient in below-grade insulation. When speaking about wall installations, Insulfoam offers a variety of insulations that cover applications ranging from exterior, interior and cavity wall applications to tongue-and-groove sheathing, whole wall, and gable end applications. Not to mention, these products are extremely lightweight and have physical properties that are well ahead of their time. But below-grade and wall installations are not all that Insulfoam is renowned for. It also makes GeoFoam, a geo-synthetic structural fill that literally exceeds the requirements of ASTM D6817 Standard Specification for Rigid Cellular Polystyrene Geofoam. This is a fantastic alternative to other fill-materials, providing excellent lateral-load support and dimensional stability as a soil and slope stabilizer in various engineered applications.  And, yes, before one asks – roofing applications are also completely covered by offering roof insulation panels that help reduce overall energy consumption, and end up creating a fantastic and comforting environment for the occupants of the building. The company has a wide-range of code-approved composite roof insulations that work with fully adhered, mechanically attached and ballasted roof systems without the need for coverboards or slip sheets. Insulfoam’s high-density composite has code approval for direct-to-combustible decks without a thermal barrier, an excellent illustration that Insulfoam products work for virtually every type of roofing system. And what’s one of the most important words to hear when it comes to building and construction products? Cost-effective! Insulfoam’s products provide some of the best R-values per dollar. These products resist almost everything, which makes these products necessary for a long list of projects ranging from highway retaining walls to parking structures to foundations, loading docks, levees, underground utility protection, railways, runways, and so much more. Are you working on an entertainment construction project that will involve theater or stadium seating? This is what you need. Working on creating that pool with deck outside? …Need I say more? Even the website that is available discussing each and every one of these products proves how efficient and up-to-date this company is. Data, research, analysis, facts, figures – even instructional and technical information is offered on each one of these products, leaving absolutely nothing to doubt. And this includes questions and data regarding global warming, RA standards and the true goal that Insulfoam and Carlisle have to decrease our ‘carbon footprint and make this a healthy place where the next generation can thrive! For more information, head to this amazing website now and get to work making that next project the absolute best and ’greenest’ it can possibly be.

Saving money with EPS Insulation

Did you know that hospitals spend more on energy per square foot than all other building types (except for food service and food sales)?  And U.S. schools spend more on energy each year than they do on computers and textbooks combined.  So how do hospital and school facility managers, architects and contractors find ways to lower energy usage costs?  Given that heating and cooling account for a large share of electricity and natural gas consumption in buildings, insulation is crucial for energy efficiency by keeping heat/cool in and out via the right type of building and roof insulation.  There are many insulation types, Facility Management and Insulfoam’s Director of Sales and National Accounts, John Cambruzzi, outline why expanded polystyrene (EPS) is growing in popularity by reducing material and labor costs while meeting energy efficient goals for hospitals and schools.

R-Tech®:  An effective roof insulation panel helps reduce overall energy consumption, creates improved comfort for the building’s occupants and provides an excellent substrate for a new or retrofit roofing system. R-Tech closed cell panels pair extremely lightweight expanded polystyrene (EPS) with factory-laminated facers for good dimensional stability and compressive strength.  They offer remarkable physical properties, including excellent moisture resistance, long term non-degenerative thermal properties and extreme resilience. Insulfoam’s EPS is also environmentally friendly and 100% recyclable, containing no HCFC’s or formaldehyde and can contribute toward LEED® credit requirements.

Premier SIPs:  Structural Insulated Panels (SIPs) are a high-performance engineered wood framing product. SIPS are manufactured with a super-insulating core of rigid expanded polystyrene (EPS) that is structurally laminated and pressure cured between two sheets of oriented strand board (OSB). When using Premier SIPs for a building’s roof, walls and/or floors, the result is a highly efficient structural building system that is extremely strong, predictable, energy efficient and cost effective.
