ROXUL COMMERCIAL ROOFING ® Understanding Climate Requirements That Drive Performance

ROXUL® COMMERCIAL ROOFING

ROXUL® COMMERCIAL ROOFING High Performance Roofing Insulation Products ROXUL®/ROCKWOOL® commercial roofing products have been available globally for more than 35 years and have been the insulation of choice for many building owners, architects and roofing consultants who are interested in roofing performance and safety. In this brochure, we begin to introduce you to our products and explain why you should specify ROXUL stone wool insulation. Our products feature a 30-year limited thermal warranty, and are competitively positioned versus other insulation materials in overall performance....

ROXUL® COMMERCIAL ROOFING HIGH PERFORMANCE ROOFING INSULATION FOR COMMERCIAL CONSTRUCTION Fire Resistant Roofing Insulation The Ultimate Insulating Coverboard ROXUL® TOPROCK DD has exclusive stone wool dual density properties that feature a higher-density top layer, providing strong point load resistance and effective load distribution to minimize puncture damage to the membrane – particularly during installation. ROXUL MONOBOARD is a rigid, mono-density roof coverboard with a uniform density that can provide tremendous versatility, and is designed for use as a coverboard and re-coverboard....

ROXUL® COMMERCIAL ROOFING Climate Driven R-Value (CDRV) Declared R-Values – Industry Standard All insulation manufacturers follow the R-value rule that requires all types of insulation to be tested in accordance with one of the standard industry test methods defined by the American Society of Testing and Materials (ASTM). The rule requires that R-value tests be conducted at a mean temperature of 23.9°C (75°F) and a temperature differential of 27.8°C (50°F). This means that insulation is usually tested with the cold side at 10°C (50°F) and the warm side at 37.8°C (100°F). Some insulation...

ROXUL® COMMERCIAL ROOFING STONE WOOL ASSEMBLIES FOR ULTIMATE PERFORMANCE DUAL INSULATION ASSEMBLY USING ROXUL 1st Recommended Design Consideration 2nd Recommended Design Consideration With recent research into roof system performance showing the effects that insulation and the membrane system can have on the performance of the building, designers now have more information to help them make better decisions on building performance. By using different materials, such as membrane, fasteners and insulation, designers are able to create optimal solutions that are economically feasible and will...

ROXUL® COMMERCIAL ROOFING Climate Driven R-value The NRCA conducted a research study after noticing a drop in thermal performance in polyiso roof boards over varying temperatures. Their original results are displayed here for your reference. The concept of climate driven R-value focuses strictly on climate or temperature when predicting R-values in situ. That is to say other factors such as aging, off-gassing, dimensional stability and thermal bridging can further reduce the expected performance of your design. Polyisocyanurate [NRCA] In recent years, BSC and RDH have also conducted their...

ROXUL® COMMERCIAL ROOFING Fire Resistant Insulation To Prevent Flame Spread And Toxic Smoke Development 2400– ROXUL® stone wool insulation has a melting point that exceeds the temperatures of most commercial fires. Therefore it will not add fuel to an existing fire, as foam plastics tend to do; making it ideal for use in high occupancy buildings. stone wool melts 400– polyurethane foam burns polystyrene foam melts ROXUL stone wool roofing insulation is non-combustible and will not develop toxic smoke or promote flame spread, even when directly exposed to fire. Time (Hours) Stone wool...

ROXUL® COMMERCIAL ROOFING Moisture Management Properties; Better Than Other Insulations Repels Water ROXUL® insulation has superior drying potential, minimizing the risk of condensation buildup – effectively managing stresses on the membrane from changes in temperature. Built-up moisture can cause the formation of blisters and ridging, which can lead to leaks and premature failure of the roofing membrane. TOPROCK® DD and MONOBOARD® are water repellent yet vapour permeable and will not promote rot, corrosion, mould or bacterial growth. Minimizing Noise With Superior Sound Absorption ROXUL...

ROXUL® COMMERCIAL ROOFING Dimensionally Stable: ROXUL Holds Up Year After Year ® ROXUL stone wool retains its physical characteristics over time. Unlike foam insulation materials, both TOPROCK® DD and MONOBOARD® have minimal contraction or expansion due to fluctuating temperatures, nor are they adversely affected by the presence of moisture – two critical factors that can compromise a building’s roofing system. Dimensional Stability Material Type Co-Efficient of Linear Expansion Actual Expansion at Temperature Difference of 50ºC on a 10 m Section Actual Expansion at Temperature Difference...
