Frequently Asked Questions
What is DryGuard OSB used for?
DryGuard Enhanced OSB is designed as a structural wall and roof sheathing product. The 1/2" Structural 1 panel should be used where its specific performance category and thickness meet the project requirements.
What makes DryGuard different from standard OSB sheathing?
DryGuard features enhanced moisture resistance throughout the panel and a black edge seal designed to help reduce moisture absorption and edge swelling.
What does Structural 1 mean?
Structural 1 is a performance category for structural wood panels with enhanced requirements for certain structural properties. Always use the panel grade stamp and project specifications to determine whether it is appropriate for a particular assembly.
Is DryGuard waterproof?
No. DryGuard is classified as Exposure 1, meaning it is designed to resist moisture exposure that can occur during construction delays and similar conditions. Exposure 1 panels are not intended for permanent exposure to weather.
Does DryGuard have an edge seal?
Yes. The panel has a black edge seal designed to help reduce moisture absorption at the panel edges.
How much area does one sheet cover?
A 4' x 8' sheet provides 32 square feet of coverage before accounting for cuts and waste.
Installation Notes
Install according to the panel grade stamp, project plans, applicable building codes, and manufacturer requirements for the specific wall or roof assembly.
Follow the specified panel orientation, fastening schedule, edge support, and panel spacing requirements. Do not assume that all OSB sheathing panels have the same structural performance or installation requirements.
Exposure 1 panels should be protected from prolonged weather exposure and should not be treated as permanently weather-exposed sheathing.
Store panels flat and protected from moisture before installation.
