The number of "plies" on a roof indicates the variety of layers, i. e. "four plies" denotes a four-layer flat roof membrane system - corrugated metal roofing. BUR systems are redundant, implying if one layer breaks down, numerous remaining layers offer immediate defense. These systems also use great tolerance for constructing tension and resistance to thermal shock, high leak resistance and exceptional membrane strength and strength for proven long-term sturdiness.
The secret to this system is the recurring layers - flat metal roof. BUR likewise is known for exceptional fire resistance from external flames. Reflective appearing alternatives likewise are readily available to provide optimal membrane defense, remarkable leak resistance and high resistance to foot traffic and mechanical maintenance. With basic application procedures, IKO BUR Systems use robust security for today's buildings and are offered in standard four-ply.
Reinforcing materials likewise are called roofing felts or ply sheets. Roofing felts are enhanced with either glass-fiber mats or organic mats. A proven waterproofing material and appropriates for use in picked moist proofing and waterproofing applications. Mod Bit systems include factory-fabricated layers of asphalt that are "modified," utilizing a rubber or plastic active ingredient for increased versatility and combined with a reinforcement for extra strength and stability.
It's discovered in natural deposits or may be a refined product and is used for both roadway appearing and roofing. Bitumen displays a thermoplastic quality when softened by heat. In modified bitumen, there are 2 primary modifiers utilized today: APP (atactic polypropylene) and SBS (styrene butadiene styrene). APP and SBS refer to the kind of polymers that are added to the asphalt.
Scrim is an enhancing fabric made from constant filament yarn in an open mesh construction. Mod Bit membranes are normally set up as a 2- or three-ply (multiply) system. The kind of modifier used might determine the technique of sheet installation: mopped down utilizing hot asphalt or heat bonded to melt the asphalt so that it streams onto the substrate.
The membrane system might be held in put on the roof by totally sticking the base sheet, mechanically connecting the base sheet or using ballast. High performance modified bitumen roof and waterproofing systems are rapidly set up, simple to maintain and cost efficient. Mod Bit membranes are typically hot mopped like conventional BUR but also might be used as a torch down product.
If hot asphalt is required for other roofing operations to adhere insulation or a base sheet, it's likely more economical to hot mop the cap sheet also. Heat welding (also described as "torch down") can evaporate surface moisture from the bonding location. Heat welding preheats and softens material, using advantages in cold weather.
A variety of specifically developed heat bonded systems are offered, consisting of Armourplast APP Heat Welded Cap Sheets, the PrevENt line of fire rated cap sheets and Torchflex SBS Membranes in both base and cap sheets. Developed to minimize labor and setup time, the IKO Torchflex Roofing System can provide large office complex and commercial warehouses with several years of security.
Roofs are considered completely adhered if applied straight to roofing system decks or insulation (cedar shake roof). From PrevENt Fire Rated Premium Strong Cap Sheets to Modiflex Cap and Modiflex Base Sheets, these long lasting totally adhered products will add strength and life to your roof. IKO Mechanically Attached Roof are understood for consistency and durability, and include those that are secured with a fastener system straight into the structure's structural deck.
IKO Fire Rated Roof are developed to deal with extreme temperature levels and to mitigate fire. The PrevENt line of premium SBS cap sheets offers boosted efficiency with graphite innovation for the highest fire resistance score (Class A) readily available in a flat roofing membrane. Graphite is applied to the upper face of the reinforcement mat throughout manufacturing of the cap sheet and functions as a fire retardant by broadening rapidly when exposed to heats.
IKO Reflective and Eco Roof deal reflective properties developed to supply protection from the damaging impacts of the sun and ultraviolet radiation. From ArmourCool to the new fire resistant Carrara ArmourCool HD, these membrane systems install like a basic cap, are strengthened and constructed to last, supplying a substantial contribution towards improving building energy performance and cost savings to the building owner.
Offered throughout the complete line of asphalt systems, these HD membrane products include Fast-N-Stick, Torchflex and Avoid membranes, along with the brand-new environmentally friendly Carrara ArmourCool HD. Premium Heavy Responsibility Composite Systems install like a basic cap and specialists can expect much better "ordinary flat" propensities with increased general strength. IKO Cold-Applied Roof consist of cold procedure adhesives that are ideal for use with vapour retarders and Modiflex Base and Cap Sheets.
