Installation process of the Sandwich Panel Three Frets

Following the guidelines and recommendations of our experts, the installation of your 3 Frets Sandwich Panel Roofing can be a quick and easy process. Below, we provide the steps to follow in the assembly process of your Three Frets Sandwich Panel Roofing:

1- Structural preparation

Before starting the installation, it is necessary to ensure that the supporting structure (metal, concrete or cement) is level, aligned and in optimum condition. It is essential that the structure is designed to support the weight and loads of the sandwich panel and the additional elements to be installed.

2- Transport and Storage

The panels must be transported and stored in suitable conditions to avoid deformation and damage. Our experts recommend storing them in a horizontal position and on flat surfaces, protected from the weather and humidity.

3- Laying of Panels

Start the installation from one end of the roof, following the direction of the inclination of the slopes. The panels should be placed perpendicular to the purlins or rafters of the structure. For ease of installation, cranes or elevators can be used.

4- Fixing of panels

It is advisable to fix the panels to the structure using self-drilling screws with sealing washers to ensure a correct joint between the panels and the structure, paying special attention to the areas of the ribs, where the panels fit together. We recommend using rivets or specific screws in the overlapping areas.

5- Joint sealing

To guarantee watertightness and prevent water and air infiltration, we recommend applying specific sealants in the joints between panels (both in the ribs and in the longitudinal overlaps).

6- Installation of additional elements

Depending on the project, it may be necessary to install additional elements such as Polycarbonate Roof Panels, Clear Plastic Roofing Sheets or ventilation systems, among others.

7- Trim and Fiishing

We suggest finishing the installation by placing specific trims and profiles for edges, corners, ridges and other elements. These trims improve the appearance and ensure greater protection against the weather in your 3 Frets Sandwich Panel Roofing, preventing animals from living in the foam and, thus, extending the life of the panel.

Maintenance of the Sandwich Panel 3 Frets

Once the installation is completed, it is necessary to carry out periodic inspections to verify the condition of the panels and perform proper maintenance. Below, we suggest a series of tips to ensure the durability and maximum performance of your Three Frets Sandwich Panel Roof:

  • Visual Check: Perform periodic visual inspections (at least once a year) to detect possible damage or deterioration of the panel surface. Pay special attention to panel joints, trim and fasteners.
  • Cleaning: Keep the surface of the panel clean, eliminating the accumulation of dirt, dust, moss and other elements that can retain humidity and favor corrosion or deterioration of the material. Use mild soap and water to clean the surface, avoiding aggressive or abrasive chemicals.
  • Humidity Control: Make sure that the drainage and water evacuation systems are working properly to avoid the accumulation of moisture on the panel surface. Constant humidity can weaken the structure of the panel and promote the appearance of rust and corrosion on metallic elements.
  • Fixation Check: Verify that the fasteners (screws, staples, etc.) are in good condition and tight. If you detect any loose or damaged fasteners, repair or replace them immediately to maintain the integrity of the panel.
  • Mechanical Damage Prevention: Avoid carrying heavy objects or performing work that may cause mechanical damage to the panel surface. If you need to access the ceiling, use suitable walkways or work platforms to distribute the weight and avoid deformation of the panel.
  • Damage repair: If you detect any damage to the surface of the panel, such as dents, cracks or holes, it is important to repair it as soon as possible. Use mastic or sealants specific to the panel material and follow the manufacturer's instructions for repairs.
  • Corrosion protection: If the panel has metallic elements, apply a layer of corrosion protection in the exposed areas to prevent the appearance of rust. Check the manufacturer's recommendations on the most suitable products for your application.
