Drew Foam also manufacturers EPS for use as insulation interior and exterior foundation walls, as foundation perimeter and sub slab foundation, and as flat foam or architecturally-shaped foam for Exterior Insulation and Finishing Systems (EIFS). EPS can also be used in wall construction. Some of the uses include: exterior sheathing, retrofit insulation and cavity wall insulation. Below is an overview of the above-listed EPS application.

Perimeter Insulation: With EPS insulation, you can select the strength and thickness to meet loading and thermal requirements. EPS also offers long-term resistance to slab edge heat loss.

Sub Slab Insulation: EPS provides an effective thermal insulation for on-grade concrete floors. EPS can also substantially reduce downward heat loss and increase the thermal capacity of floor slab.

Exterior Foundation Walls: Attach EPS with a spot adhesive. If EPS is exposed above grade, use a suitable protective exterior coating. EPS also provides effective protection for you waterproofing layer.

Interior Foundation Walls: EPS can be used for heated crawl spaces and basement areas. It also supplements batt insulation between floor joists. If you plan to use EPS for insulation on interior foundation walls, apply a suitable thermal barrier such as ½” gypsum board to wood furring, z-furring or thermal studs.

Exterior Sheathing: EPS meets or exceeds current energy conservation design standards without increasing stud width. You can reduce air infiltration and heat loss through framing; and slow convective looping. Non-structural sheathing requires corner bracing. Foil faced EPS with air space can provide additional R-value and retard radiant heat flow using perforated foil promoted breathability. EPS exterior sheathing also eliminates the need for extra deep framing.

Retrofit Insulation: EPS supplements existing insulation and can be easily applied during modernization or during remodeling. A variety of sidings or finishes can be used with EPS backer board.

Exterior Finish Insulation: EPS reduces thermal movements and stresses in the wall, and it helps to eliminate “cold spots” on the interior of the wall. EPS in this application can also help reduce peak demands for heating and cooling.

Drywall Base: EPS provides a self furring, solid base for adhesive application of gypsum board. However, supplementary furring is recommended for the integrity of the gypsum board thermal barrier. EPS can be attached to a masonry wall with adhesive, mechanical fasteners, z-furring or thermal studs.

Cavity Wall: EPS provides high thermal performance and resistance to moisture. EPS is easily fabricated; drop it in during layup and impale to wall ties or aplly spot adhesive to block. Maintain a ?” of air space between EPS and outer wall for minimum moisture penetration.
