Operation and Installation Instructions

Proper handling and installation ensure optimal performance and longevity of XPS boards.

Step-by-Step Installation Guide

  1. Site Preparation

    • Ensure the surface is clean, dry, and level.

    • Remove debris, dust, or sharp objects that could damage the board.

  2. Board Cutting

    • Use a sharp utility knife, hot wire cutter, or saw to cut boards to size.

    • Ensure straight, accurate edges for tight-fitting joints.

  3. Placement

    • Position boards directly on the surface (floor, wall, or roof).

    • For overlapping joints, stagger edges to prevent thermal bridging.

  4. Fixing

    • Use mechanical fasteners, adhesive, or a combination for secure placement.

    • Ensure boards are flush and level to prevent gaps or uneven surfaces.

  5. Sealing

    • Apply joint tape or sealant at board edges to improve waterproofing and thermal efficiency.

    • Check for tightness and uniformity across all boards.

  6. Final Inspection

    • Verify alignment, adhesion, and surface integrity.

    • Correct any gaps or misaligned boards before proceeding with finishing layers.

Usage Tips

  • Avoid direct exposure to sunlight for prolonged periods during storage.

  • Do not overload boards during installation, especially in vertical applications.

  • Always wear protective gloves and eyewear when cutting or handling boards.

  • Ensure proper ventilation when using adhesives or sealants for installation.


Maintenance and Care

XPS boards require minimal maintenance, but regular checks ensure maximum durability and performance:

Maintenance TaskFrequencyMethod / Notes
Surface CleaningAs neededWipe with damp cloth; avoid abrasive cleaners
InspectionEvery 6–12 monthsCheck for moisture infiltration, cracks, or displacement
Joint SealingAs neededReapply sealant if gaps appear
Protective CoatingOptionalApply coatings in high-wear or outdoor areas
