Expanded Polystyrene Roof Insulation

Thermal efficiency at a low Cost
LIFOAM™ Stryoshield Roof Insulation products begin with a modified expanded polystyrene foam. This rigid, cellular foamed plastic combines light weight and high strength with exceptional thermal properties and moisture resistance. The long term insulating performance of LIFOAM™ Styroshield Insulation is one of the highest in the industry. Tests conducted by SPI, MRCA and NRCA have concluded that EPS maintains close to 100% of its manufactured R-Value and is very resistant to moisture.

Features and Benefits
Lightweight - easily lifted to rooftop and adds little additional weight
Versatile - can be used with any roofing system, easy to cut and shape.
Cost efficient - best thermal efficiency of any insulation on the market, helps reduce HVAC operating costs and saves energy.
Stable - predictable, long term R-Value

Moisture Resistance
A study by the Energy Materials Testing Laboratory (EMTL) has shown that EPS insulation installed in well-constructed roofs does not absorb appreciable moisture, even under conditions characteristic of prolonged, cold, damp winters. The small amount of moisture absorbed (an average of 0.2% by weight) has little or no effect on the compressive or flexural strength, and the EPS insulation retains between 95% and 97% of its thermal efficiency

Though it has low water vapor transmission, EPS is not a vapor barrier. Rather it "breathes", and therefore needs no costly venting as do some other relatively impermeable insulation materials which could otherwise trap moisture within walls and roof assemblies.

Flammability
As with organic materials, products manufactured from expandable polytyrene must be considered "combustible" when directly exposed to fire.

Roof Insulation Products
Various roof insulation products, developed by LIFOAM™, LLC. offer great design versitility to meet a wide range of job conditions. Equally suited to new construction and roofing applications, these EPS insulation products provide the greatest R-value at the lowest cost.
 
Conventional

Tapered

Composite Board
 
Tapered Insulation
A custom design is engineered for each tapered insulation application. A detailed shop drawing is supplied for architectural approval on all projects. All hip and valley lines are at 45° angles, when possible, so that a factory miter can be supplied (other angles must be field cut). Special sizes are produced to reduce field cutting. All delivered material is coded to match plans. Assistance is available in establishing drainage patterns for any particular project.
 
Ballasted Roof Over Metal Deck


Roof Systems

Deck
-Metal - A thermal barrier between EPS and the metal deck is a building code requirement. i.e. 5/8" gypsum board, 3/4" perlite, 1" plain or asphalt impregnated wood fiberboard or other approved thermal barriers.
-Concrete - EPS may be applied directly to the concrete deck
   
Vapor Barrier
- Optional
   
EPS - The density ranges from 1-2 lbs/ft and can be either flat or sloped

Overlayment - Required for BUR, mechanically fastened, fully adhered

Seperation Sheet - Required for some membranes

Membrane - BUR or Single Ply ballasted or unballasted
