1. Preparing the structure
The structure must be level and clean. Any deviation shows at the panel joints, so it is checked before installation.
2. Fixing the panels
Panels are fixed with fasteners suited to the thickness and structure type, keeping the spacing in the design. Installation starts from a straight reference so the lines stay parallel.
3. Sealing the joints
Joints, corners and eaves are where thermal bridges and leaks appear. They are sealed carefully, as are the openings for doors and windows.
4. Common mistakes
The most common problems are:
- Too few or overtightened fixings
- Unsealed joints at corners
- Panels stored or cut incorrectly
- Missing trim profiles
5. Who installs
Installation by the same crew that raised the structure avoids mismatches. See our page on sandwich panel installation.
