Lamtec – Facings for the Building Industry

Lamtec manufactures a wide variety of vapor barriers and facings. These products range from low cost light duty to premium heavy duty barriers with specific applications.

R-3035

Lamtec R-3035 is a foil scrim kraft vapor retarder and air barrier. It is composed of aluminum foil, fiberglass and polyester scrim and 30# natural kraft. It has a water vapor transmission rate of 0.02 US perm, a fire performance of less than 25 flame spread/50 smoke developed, and meets ASTM C1136, Type II and IV.

R-3035-HD

R-3035 HD is a different type of reinforced facing. It is made with heavy duty foil, scrim and kraft paper. It has a permeance of 0.02 perm and a bursting strength of 60 psi. This makes it a good vapor barrier for moisture control, but a better choice in areas that are not susceptible to damage like rips, tears and holes.

WMP-10

WMP-10 has polypropylene on the front side and white kraft paper on the back side. It is slightly heavier than WMP-VR so it can stand up to light to moderate traffic. The white kraft paper provides a better water vapor barrier (0.02 perm) and a little more resistance to impact (65 psi bursting strength).

WMP-30

Similar to WMP-10, WMP-30 has a polypropylene front and white kraft paper back but adds additional thickness and strength. It is better suited for heavier duty jobs and in areas with moderate to heavy traffic. While it has the same vapor barrier strength as WMP-10 (0.02 perm), WMP-30 is superior in terms of bursting strength (70 psi).

WMP-50

WMP-50 has polypropylene on the front side and metallized polyester on the back side. It is twice as heavy and strong as WMPVR-R making it a good choice for metal buildings when the walls are exposed to heavy traffic and abuse. It is a premium heavy duty product with a permeance of 0.02 perm and bursting strength of 120 psi.

WMP-RETRO

WMP-RETRO is a premium heavy duty, highly abuse resistant vapor retarder designed for re-covering damaged faced insulation. It is composed of WMP-30 laminated to a fiberglass mat/scrim/aluminum foil structure. It has a water vapor transmission rate of 0.02 perm and a fire performance of less than 25 flame spread/50 smoke developed.

WMP-RETRO SILVER

WMP-RETRO SILVER is a premium heavy duty, highly abuse resistant vapor retarder designed for re-covering damaged faced insulation. It is composed of R-3035 laminated to a fiberglass mat/scrim/aluminum foil structure. It has a water vapor transmission rate of 0.02 perm and a fire performance of less than 25 flame spread/50 smoke developed.

WMP-UV-HD

WMP-UV HD has a polypropylene front and metallized polyester back but adds additional UV resistance. It is also twice as heavy and strong as WMPVR-R. It matches WMP-50 in terms of permeance and bursting strength. It is particularly well-suited to building applications with large amounts of sunlight.

WMP-VR-R-Plus

WMP-VR-RPLUS is polypropylene faced and metallized polyester backed. It is the most commonly used type of reinforced facing. The metallized polyester backing provides additional strength and water resistance. It has a permeance of 0.02 perm and a bursting strength of 100 psi. It is used in metal buildings that do not require heavy facing.

WMP-VR

WMP-VR has polypropylene on the front side and natural kraft paper on the back side. This is one of the most affordable reinforced facings the lowest priced reinforced facing available, and it is the industry standard used in typical metal buildings that only require standard duty insulation. It is 0.09 perm and has a bursting strength of 60 psi..

ArenaShield

ArenaShield is a highly abuse resistant vapor retarder and air barrier used in ice arena facilities. ArenaShield is composed of aluminum foil, fiberglass and polyester fabric. It has a water vapor transmission rate of 0.02 perm and a fire performance of less than 25 flame spread/50 smoke developed.

GymGuard

GymGuard is a highly abuse resistant vapor retarder and air barrier used in athletic facilities and high traffic areas. GymGuard is composed of polypropylene film, metallization, fiberglass and polyester fabric. It has a water vapor transmission rate of 0.02 perm and a fire performance of less than 25 flame spread/50 smoke developed.
