How should EPS sheets be joined?

Joining EPS (Expanded Polystyrene) sheets with compatible glue or approved tape is the correct method because it ensures a strong, reliable bond that maintains the integrity of the insulation. This technique is important for several reasons: it allows for an effective sealing of joints, which can contribute to thermal efficiency and moisture control. Utilizing the correct adhesive or tape that is specifically designed for EPS helps to avoid chemical reactions that could damage the material, maintaining the insulation's structural and insulating properties over time.

In contrast, using duct tape may not provide the necessary strength or compatibility with the EPS material, which can lead to failure in the joints over time. Welding techniques could potentially damage the EPS, as the heat applied during welding can melt or deform the material. Standard construction adhesive may not always be appropriate, as it may not be specifically designed for use with EPS and could result in ineffective bonding or chemical deterioration. Therefore, compatible glue or approved tape is the most effective and safe method for joining EPS sheets.
