An extremely flexible torch-applied SBS membrane.  Fastorch SBS is superior to APP membranes because the asphalt is modified with Styrene Butadiene Styrene (SBS) a synthetic rubber, providing it with a rubberized property. APP membranes are manufactured by blending the asphalt with Atactic Polypropylene (APP), which is basically asphalt that has been modified with plastic.  The addition of SBS to rubber makes the membrane easier to apply than other products, with better adhesion to metal and end laps.

Fastorch SBS is available in smooth and granulated surfacing.

Various reinforcement options are available: This includes polyester, glass, and dual reinforced membranes.

A highly elastic polyester-reinforced membrane. The flexibility of the product makes it ideal for flashing and single ply applications. Superflex membranes can be applied over one layer of layflat SBS / layfast SBS base, and it qualifies for a 10 year warranty. Since only one application of asphalt / adhesive is needed, there is tremendous savings in labor and asphalt costs. Superflex membranes are available in smooth and granulated surfacing.

Various reinforcement options are available: This includes polyester and dual reinforced (polyester & glass reinforced) membranes.

Superflex SBS offers versatility of application with hot asphalt or cold adhesive.


Our family of SBS-modified base sheets. Layflat SBS minimizes buckling, wrinkling, and fish mouths associated with unmodified base / plies.    Layflat SBS is used as a base / ply, and is covered with one of our cap sheets.

Layflat SBS is available in four weights, 25-40-50 & 60 lbs/square, to meet most job conditions.

Various reinforcement options are available: This includes polyester, glass, and fiberglass scrim.

Layflat SBS offers versatility of application with hot asphalt, cold adhesive, or mechanical fasteners.

A superior and competitively priced alternative to traditional 30 & 40 lb organic felt.  The addition of SBS rubber to asphalt gives Layfast an elastomeric property that is not available in common felt.  Layfast SBS contains a higher percentage of asphalt for increased waterproofing.  Its inorganic fiberglass reinforcement eliminates the rot and deterioration associated with saturated felt.

Layfast SBS is available in three weights, 35-43-70 lbs/square.  It can be used in lieu of 30 & 40 # felt as an underlayment under shingle, tile, and metal roofs.

Layfast SBS is ICC (formerly ICBO) approved and complies with ASTM D226 standards, which most tile, shingle, and metal manufacturers require.

We have developed a motion graphic and landing page which you can use to present features and benefits of layfast to your customer (home owners, architects etc.)

MBTechnology’s “Ice & Moisture Block SBS” is a self-adhesive, SBS-modified, rubberized asphalt membrane.  The Ice & Moisture Block provides extra protection and prevents moisture penetration from windblown rain or ice damming. It is applied over critical roof areas such as eaves, ridges, valleys, dormers, and skylights. The sealing adhesive is protected on the bottom with a split release sheet which is removed during application.

Ice & Moisture Block is available in three grades:

 SA65G:   Manufactured with fine granule surfacing; ideal for tile & shingle roofs.

SA65S:  Manufactured with a smooth sand finish which enables the membrane to also be used as a self-adhesive base for APP & SBS systems.


In areas that experience rain or snowfall followed by freeze-thaw cycles, the problem of ice dam buildup is of great concern in building design. This condition is caused by a meltdown of snow/rain, which then freezes to form an ice dam that prevents proper drainage. Water backs up behind the ice dam, gradually forces its way under shingles and onto the roof deck, enters the building structure, and then causes extensive water damage.


  • Fine granule/textured film surfacing provides enhanced skid resistance.
  • Available with a higher softening point compound and film surfacing for use under metal roofs.
  • Rubberized asphalt compound seals around nails and screws.
  • Split release film provides faster and easier installation.

Ice & Moisture Block can be left exposed for 30 days before the application of a finished roof.
