STYROFOAM™ Brand Insulation is the original extruded polystyrene foam insulation, invented by Dow and the first in a portfolio of products that would continue to grow and evolve to meet the needs of the building and Scoreboard Insulation. Description: Dow STYROFOAM Brand Scoreboard. It is an extruded polystyrene foam insulation board. Uses: Exterior cavity wall and foundation applications. STYROFOAM™ Brand Scoreboard Insulation has excellent insulating characteristics, high resistance to water and water vapor, exceptional compressive.

The quick answer is: The key factor is moisture, which can be controlled by adhering to sound construction practices. Keep product tarped or covered to protect from weather. All the weights are for boards of 1″ thickness 1′ x 1′ square. To get weight of 1-inch x 4 feet x 8 feet board multiple the value in table by Subscribe to Premium Services Searches: Use our self-guided Canadian Code Assessment Engine to compare above grade wall strategies for building materials and design methods aligned to local code requirements.

This further reduce the potential for mold and mildew growth.

DOW STYROFOAM™ Scoreboard Insulation Board

Mold and mildew are nuisances every architect wants to avoid. However, Terra cotta, metal panel and fiber styrrofoam siding veneers will probably not appreciably increase the R-value of the system. Walls constructed with proper construction techniques and using an appropriate thickness of insulating sheathing will: They resist moisture absorption in the insulation itself.


Foam boards are lightweight and loose boards can be blown around by wind. Questions or comments about MatWeb? Please read our License Agreement regarding materials data and our Sttrofoam Policy.

Condensation may occur when water vapor permeates through the wall, cools and condenses on the first cold surface it encounters. Looking at Canada in styrotoam, extruded polystyrene insulation products are covered by scorboard standard ULC S, which does NOT specify a density requirement.

It should be noted that there are other performance properties listed in ASTM C that are often more important to consider when choosing the proper product for an intended application.

Top 6 Questions of Rigid Insulation

Our building scientists want to help you succeed. To make matters worse, condensation can be a source of moisture and a potential contributor to mildew growth. Our building science experts can perform a customized cost-to-build and performance analysis of your assembly to ensure the building envelope of your project is optimized. Property Data This page displays only the text of a material data sheet. Example- Thermax Light Duty 1-inch x 4ft x 8ft weighs 0. With increased attention on resiliency and building code requirements of late, the most asked wtyrofoam are about mildew, flame spread requirements, and how to material storage.

We understand that completely. To be clear, no building assembly is likely to be completely free from the potential for mold formation, but good building practices unrelated to insulated sheathing will further reduce the potential or mold formation.


MatWeb is intended for personal, styrofam use. There may be variances among boards. Type X with minimum density of 1. The contents, results, and technical data from this site may not be reproduced either electronically, photographically or substantively without permission from MatWeb, LLC.

If product does get wet, allow it to air dry before covering with exterior coverings. Ultimately, good construction detailing, compliance with proper installation guidelines for materials, and maintenance of the wall system are key to managing the moisture infiltration into the building envelope. They can grow wherever sufficient moisture, spores, optimal temperatures and nutrients are present. We also ask that you refer to MatWeb’s terms of use regarding this information.

One of the ways to manage moisture is to add insulation such that the condensing surface is not inside the wall system. As architects have likely heard, density is sometimes used to select a rigid foam insulation material for a particular application.
