Safety Precautions

Prior to installation, review all safety guidelines to prevent injury and ensure correct application.

Hazard	Precaution
Sharp Edges	Wear cut-resistant gloves when handling panels
Adhesive Fumes	Work in well-ventilated area; use respirator if needed
Heavy Lifting	Use two-person lift for large panels; employ mechanical aids
Electrical	Ensure work area is de-energized if near wiring
Eye Protection	Wear safety glasses during cutting or sealing

WARNING! Failure to follow safety instructions may result in personal injury or improper installation.

Kit Components & Tools Required

Verify all components are present before beginning installation.

ThermoLite 401414 Panels: (Qty as specified) - Rigid foam insulation with vapor barrier
Adhesive Cartridges: Polyurethane-based adhesive (2-part)
Sealant Tape: Butyl rubber tape for joints
Fasteners: Stainless steel screws and washers
Corner Reinforcements: Pre-formed aluminum corners

Required Tools: Caulking gun, utility knife, measuring tape, level, drill with bits, rubber mallet, cleaning solvent.

Pre-Installation Preparation

Proper surface preparation is critical for adhesion and performance.

Surface Cleaning: Remove all dirt, grease, and old sealant from substrate using approved cleaner.
Inspection: Check substrate for flatness (max 3mm deviation over 1m). Repair any irregularities.
Measurement & Layout: Measure installation area and plan panel placement to minimize cuts.
Climate Conditions: Install only when ambient temperature is between 40°F (4°C) and 95°F (35°C).

CAUTION! Do not install on wet or frozen surfaces. Allow sufficient drying time after cleaning.

Panel Installation Procedure

Follow step-by-step instructions for secure panel mounting.

Adhesive Application: Apply adhesive in continuous bead (10mm diameter) along panel perimeter and in zigzag pattern across center.
Panel Placement: Position panel against substrate, align with reference marks, and press firmly.
Temporary Support: Use bracing tape or mechanical supports to hold panel in place for initial set (approx. 20 minutes).
Fastening: Once adhesive begins to set, install mechanical fasteners at specified centers (typically 300mm).
Sequencing: Install adjacent panels, maintaining 2-3mm gap for thermal expansion.

Tip: Work from one corner outward to ensure alignment. Check level after each panel.

Sealing & Joint Treatment

Proper sealing ensures vapor barrier integrity and thermal efficiency.

Joint Preparation: Clean joint surfaces with solvent and allow to dry.
Primary Seal: Apply butyl tape into joint, compressing to 50% of original thickness.
Secondary Seal: Over tape, apply compatible polyurethane sealant, tooling to smooth finish.
Corner Sealing: Install pre-formed corner reinforcements, sealing all edges.
Penetrations: Seal around any conduit or fittings with flexible sealant.

WARNING! Do not stretch tape during application. Ensure continuous seal without gaps.

Curing & Final Inspection

Allow proper cure time before putting into service.

Adhesive Cure: 24 hours at 70°F (21°C) for full strength. Longer at lower temperatures.
Sealant Cure: 4-6 hours skin time; 24 hours full cure.
Inspection Checklist:
- All panels securely fastened
- Joints fully sealed with no gaps
- Surface clean and free of damage
- Vapor barrier continuous
Performance Verification: Conduct thermal imaging or air leakage test if specified.

Troubleshooting

Issue	Possible Cause	Corrective Action
Panel adhesion failure	Surface contamination; improper temperature	Re-clean surface; ensure ambient temperature within range
Gaps at joints	Insufficient sealant; tape stretching	Remove old sealant; reapply with proper compression
Panel warping	Uneven substrate; improper support during cure	Shim substrate; add temporary bracing
Condensation forming	Vapor barrier breach; inadequate sealing	Locate and repair breach; verify continuous seal
Fastener pull-out	Over-torquing; incorrect substrate	Use correct torque setting; verify substrate suitability
