Approvals & Certifications
UL listed for Class A and B fire rated roof coverings.
FM approved. Subject to the conditions of approval as a roof coating when installed as described in the current edition of the FMRC approval guide.
Consult UL and FM listings.
Uses:
modified PLUS NP180p/p Base Sheet is designed for use as the base or first ply in a high performance two-ply modified bitumen system, or as a single ply when not exposed, and for fillets and detailing. Main applications are for tanking, balconies and roofing and for waterproofing of planters.
Features:
SBS polymer provides flow resistance at high temperatures and flexibility at low temperatures for lasting durability.
Non-woven polyester 180g/m2 reinforcement.
Designed for application in new construction, re-roofing and retrofit roofing.
Excellent tear resistance.
Limitations:
Non-resistant to oils and solvents. Refer to manufacturer for specific chemical resistance. Not designed for permanent exposure. Install modified
PLUS
granule surfaced cap sheet over base sheet for permanent exposure.
Storage:
Store rolls on end, on original pallets or elevated platform. Protect from weather or store in an enclosed area not subject to heat over 120
oF.
Surface Preparation
Refer to
modified
PLUS
General Specifications for preparation and acceptable substrates.
Application:
modified
PLUS
NP180p/p
must be torched or nailed to substrate. Roll out
modified
PLUS
NP180p/p
and allow to relax prior to application.
Begin application of the base sheet at the lowest edge or drain. Proceed up the slope from the lowest point. Position and unroll base sheet to achieve correct overlap and alignment. Re-roll one end a minimum of 10' and adhere membrane to substrate. Complete application of remainder of sheet.
Torching Application:
Heat lower surface of membrane. Sufficient heat must be applied to melt the lower surface and provide a flow of bitumen as the roofing membrane is unrolled. Care should be taken to ensure that heating is even across the width to avoid skips or voids.
790-11 Application:
Torch to primed substrate as described above. Scorch film on top surface prior to over coating with 790-11.
Slopes 1:12 (1" in 12") or Greater
: In addition to the above, apply membrane parallel to direction of slope and blind nail or mechanically fasten membrane at end or head lap on 6" centers |
