P244 is a roving produced by assembling E-glass strands, wound without twisting into cylindrical cheeses.
P244 uses a sizing system (medium solubility type) with a silane coupling agent.

495 conventional roving is manufactured with state-of-the-art equipment, innovative chemistry and a major commitment to statistical process control. The quality Management Program of Owens Corning manufacturing is certified as meeting the requirements of ISO 9002. Owens Corning 495 roving is manufactured from a collection of continuous glass filaments gathered, without mechanical twist, into a single bundle. The roving is then wound and shipped in a tubeless package ready for use in cstomer continuous operations.

P243 is a roving produced by assembling E-glass strands, wound without twist onto cylindrical cheeses. It is specially designed for the manufacture of translucent panels, using all types of cutters.
P243 has a sizing system with a silane coupling agent.

P244C is a multi-end E-glass roving designed for chopping application with various types of chopping  machines. P244C sizing is of medium solubility and contains a silane as coupling agent. Due to its outstanding characteristics, P244C roving is recommended for: Car headliners, Manufacture of panels, complexes and felts, Reinforcement of plaster.

P246 has been designed for applications where the rovings are chopped and especially for: the reinforcement of car headliners, the reinforcement of plaster, the manufacture of panels, complexes and felters, the filament winding processes with choppable roving, the Drostholm process (chop and drop).

P223 is an assembled E-glass roving for the manufacture of complexes. It has a very good wet out in thermoset resins and it is particularly suitable for needled mat manufacturing.

P244 is designed for applications such as headliners reinforcement, the manufacture of panels, complexes and felts, plaster reinforcement. The Advantex® glass fiber combines the electrical and mechanical properties of traditional E-glass with the acid corrosion resistance of E-CR glass.
