Stone Wool Delivers Stable R-Values at Extreme Temperatures

Test data from a ten-year NRCA-sponsored study on aged R-values reported at the International Roofing Expo in Feb. 2010 show that tested R-values for polyisocyanurate insulations are lower than the LTTR and somewhat lower than the polyisocyanurate ASTM standard C 1289. The NRCA recommends that total in-service thermal resistance be calculated on the basis of an R-value of 5.6/inch and further recommends that “it may be prudent for designers to use an even lower R-value when designing for cold conditions, such as in northern climates or cold-storage applications”. ASTM C 1289 requires the R-Value to be measured at four temperatures. For polyisocyanurate, a peak R-value of 5.70 is obtained at 75°F (24°C) and drops to 4.74 at 25°F (-4°C) and 5.05 at 110°F (43°C).

Q&A: Fastener Requirements for ROXUL Insulation

Q: What are the FM fastening rates for MONOBOARD® Plus?
A: ROXUL has various FM approvals for MONOBOARD® Plus. For most mopped and torched modified bitumen and 3-ply BUR assemblies six fasteners per 4’ x 4’ board are required for an FM 1-75 approval. For select mopped and torched modified bitumen assemblies eight fasteners per 4’ x 4’ board are required for an FM 1-90 approval.

Steel & Ice Ball Impacting of PVC & TPO with ROXUL Mineral Wool

In a recent Laboratory study, thermoplastic single-ply membranes supported by ROXUL mineral wool insulation were tested in accordance with FM 4470, and UL 2218, and ice balls in accordance with FM 4473. The conclusion of this independent Laboratory study is that, PVC and TPO thermoplastic single-ply membranes supported by ROXUL mineral wool insulation are not damaged by impacts with steel balls in accordance with FM 4470 (Class 1-SH) and UL 2218 (Class 4), and ice balls in accordance with FM 4473 (Class 4).

Moisture Management Properties of ROXUL TOPROCK® DD Roof Insulation

An important benefit of TOPROCK® DD is its ability to allow trapped vapors in a roof assembly to disperse throughout the insulation layer. The Water Vapor Permeability of TOPROCK® DD is approximately 30 Perm, as measured in accordance with ASTM E 96-05 ‘Standard Test Method for Water Vapor Transmission of Materials’. TOPROCK® DD is water repellent, resisting the infiltration of water into the insulation layer. The structure and integrity of stone wool insulation is not affected by the presence of water. Water exposure from leaks in the roof membrane or from condensation within the assembly can be removed by allowing the insulation to vent this moisture. Stone wool will quickly dry out to become fully restored and retain its original

R-Value Claims of Polyisocyanurate Insulation

Based on the PIMA statement, Polyisocyanurate manufacturers base R-Value claims on the LTTR criteria as an accepted Industry standard value. PIMA has issued the following statement with regard to LTTR: Polyiso roof insulation users are primarily interested in R-value - the measure of the product's thermal performance. Since 1981, the polyiso foam insulation industry has been using PIMA 101 (RIC/TlMA 281-1), a six-month conditioning procedure to report Rvalue. This practice allows for an "apples to apples" comparison of R-values from different manufacturers. The polyiso industry has begun a transition to a new methodology to determine the thermal insulation efficiency of their permeably faced products. LTTR represents the most advanced scientific method to describe the Long-Term Thermal Resistance of foam insulation products using blowing agents other than air, including polyiso, polyurethane and extruded polystyrene.
