Why It’s Ideal for Van Conversions

The Dometic Mini Heki Style is one of the most popular skylights for modern van conversions and camper upgrades.

Installation & Usage Notes

• Fits roof thicknesses from 25 to 42 mm.
• Always check the installation area before cutting — ensure no beams, electrical cables, or structural supports are in the way.
• Use a high-quality polyurethane sealant (e.g., Sika Lastomer or Fix-It MS Polymer) to ensure a watertight fit.
• Install the dome with its hinge facing forward to minimize wind lift during driving.
• After installation, remove the protective film and test all opening positions.
• For maximum insulation, ensure even sealant coverage and proper tightening of all mounting screws.
