Membranes

We pioneered built-up roofing systems in America more than 160 years ago. Our highly reliable waterproof membrane is field-fabricated with layers of bitumen, alternating with plies of reinforcing felts.

The redundant layers give roofs exceptional resistance to water and weather. As a result, we have long-lasting, durable and worry-free systems. Few roofing companies can claim to have created nearly one billion feet of BUR that are today under full guarantee.

Fiber glass-reinforced, SBS copper foil-surfaced cap or flashing sheet.

Meets or exceeds the criteria for ASTM D 6298

DynaClad Copper is used as a fiber glass-reinforced cap or flashing sheet in a variety of multi-ply roofing systems.

Copper Foil Surface: Provides high reflectivity, reducing heat load on the roof membrane and potentially lowering air conditioning energy costs.

High-Quality SBS Rubber and Asphalt Blend: Lends elasticity and flexibility to the sheet. The elongation and recovery properties allow the product to easily accommodate the continual expansion and contraction experienced on all roofs.

Fiber Glass Reinforcement Mat: Offers excellent dimensional stability and tensile strength and withstands differential movement. Because it has no thermal memory less time is needed to relax the sheet, allowing for ease of installation. The fiber glass mat also has good lay-flat characteristics.

GlasPly Premier is intended for use as an interply in any built up roofing or modified bitumen roofing system.

Excellent Porosity: Allows the product to readily accept hot asphalt and disperse it throughout the entire felt, to stabilize the asphalt after cooling.

Asphalt Impregnated, Fiber Glass Reinforcement Mat: Delivers high tensile strength to resist splitting that can be caused by rooftop stresses. Low moisture, excellent dimensional stability and resistance to rot make it an ideal replacement for organic ply sheets. Provides a solid dimensionally stable substrate for other roofing membrane components.

Laying Lines: Before the product is wound into rolls, it is imprinted with laying lines on the top surface so the roofing mechanic can install the felt with the proper exposure and provide the correct number of plies

Surfacing: Liquid parting agent eliminates sticking when the felt is unrolled.

Polyester/fiber glass-reinforced, asphalt-coated base, ply or flashing sheet.

Meets the requirements of ASTM D 4601, Type II 

GlasTite Flexible is intended to be used as a base sheet, ply sheet, or flashing membrane in built up roofing systems.

Fiber Glass/Polyester Composite Reinforcement Mat: Provides superior flexibility and conformability, making it easy and quick to install. Exceptionally high tensile strength delivers superior protection against splitting as well as excellent puncture and tear resistance to prevent damage often caused by rooftop traffic.

Ideal for Flashing Systems: Superior flexibility and conformability allows the mechanics to easily and quickly install tight flashing systems and make it ideal for all roof terminations, including parapet walls, skylights, roof penetrations, drains, vents and roof edges. GlasTite Flexible does not bridge at the cant and will not pull away from the substrate after it has been installed.

Laying Lines: Laying lines are imprinted on the top surface so the roofing mechanic can install the felt with the proper exposure and provide the correct number of plies.

Surfacing: Fine mineral parting agent

Fiber glass-reinforced, asphalt-coated lightweight base sheet.

Material meets the requirements of ASTM D 4601, Type II

PermaPly 28 is designed for use as the first or base sheet in built up roofing or modified bitumen roof assemblies.

Lightweight: Exceptionally pliable, easy to handle and lays flat.

Asphalt Coating: Makes it suitable as an intermediate or ply felt in cold-applied built-up and modified bitumen roof assemblies.

Ideal for Mechanical Attachment: Use where mechanical attachment of the membrane to the roof substrate or deck is desired.

Fiber Glass Reinforcement Mat: Low moisture, excellent dimensional stability and resistance to rot make it an ideal replacement for organic base or ply sheets. Provides a solid dimensionally stable substrate for other roofing membrane components.

Laying Lines: Laying lines are imprinted on the top surface so the roofing mechanic can install the felt with the proper exposure and provide the correct number of plies.

Surfacing: Fine mineral parting agent.

Fiber glass-reinforced, asphalt-coated venting base sheet.

Material meets the requirements of ASTM D 4897, Type II

Ventsulation Felt may be used as a base sheet for any built up roofing or modified bitumen roofing system to be installed over a substrate that potentially contains moisture.

1" Embossed Waffle Pattern Grid Channels: Promotes moisture vapor venting. Helps prevent blistering of asphalt-based roofs when installed over potential moisture-containing substrates such as: Re-covers over existing roof membranes, lightweight insulating fill or gypsum decks.

Fiber Glass Reinforcement Mat: Low moisture, excellent dimensional stability and resistance to rot make it an ideal replacement for organic base sheets. Provides a solid dimensionally stable substrate for other roofing membrane components.

Surfacing: Coarse minerals on one side.
