Product Feature: Code Approved, High Performance Metal Flute-Fill Insulation

InsulFoam Flute Fill

InsulFoam Flute Fill

Insulfoam FL (Flute Fill) is a custom-cut, high performance insulation for standing seam metal roofs in need of insulation and a roof membrane.  Insulfoam FL is versatile enough to be used across any metal deck (24 /26 ga) and can be combined with a variety of Insulfoam insulation products to build a code-approved metal-retrofit system.

InsulFoam FL can be taper-cut or square-cut to fit the metal roof system’s flutes, and can be designed to fill virtually any profile of the existing metal roof.  It comes in multiple thicknesses, widths and compressive strengths and can also be customized with taper or bevel-edges to provide a continuous seam over the flute.


  • Versatile:  InsulFoam FL can be manufactured in a range of sizes, densities, thicknesses and profiles to meet any job-specific needs.
  • Cost-Effective:  InsulFoam FL reduces concerns with flute span ability and minimizes the need for additional insulation.  Minimizing the use of insulation above the flutes also redoes the possible need to raise curbs and other rooftop units.
  • Environmentally Friendly:  InsulFoam FL contains no formaldehyde or ozone-depleting CFCs or 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.
  • Water-Resistant:  InsulFoam FL does not readily absorb moisture from the environment.
  • Proven Performance:  Insulfoam has been making engineered EPS insulation since the mid-1950s, so the actual performance of the product is well known.
  • Sizes:  InsulFoam FL is custom-manufactured for each specific application, and is readily available in a variety of lengths, widths and shapes to meet virtually any job condition.

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.
