When installing FRP transparent skylights, it is important to pay attention to the following key aspects:

Preparation Phase

Material Inspection:

Before installation, carefully inspect the quality of the FRP transparent skylight panels. Check for any defects such as scratches, bubbles, or cracks on the surface of the sheets. These imperfections may expand after installation, affecting the performance and lifespan of the skylight panels.

Ensure the specifications of the light panels meet design requirements, including length, width, thickness, and wave peak shape and dimensions. For instance, if the wave peak size does not match the spacing of the roof joists, it may result in unstable installation.

Tool Preparation:

Ensure you have the appropriate installation tools on hand, such as an electric screwdriver, manual screwdriver, sealant, craft knife, tape measure, and level. These tools will be used for cutting skylight panels, securing screws, and applying sealant.

Ensure the quality and safety of tools, such as adjusting the torque of an electric screwdriver properly to avoid damaging the采光板 during screw tightening.

2. Installation Environment

Weather Conditions:

Minimize installation during adverse weather conditions such as rain, snow, or strong winds. Rain may seep into the gaps of the light-transmitting panel installation, causing leaks; strong winds may compromise the safety of installation personnel and increase the risk of damage to the panels during installation.

Temperature during installation is also crucial. If it's too low, the采光 panels can become brittle and prone to cracking during installation; if too high, the material may become soft, affecting installation accuracy. The ideal installation temperature typically ranges between 5 - 35℃.

Installation Site Cleanup:

Prior to installation, the installation area on the roof or wall must be cleared, ensuring the surface is flat, clean, and dry. Any debris, dust, or oil stains on the surface may affect the bonding and sealing performance between the采光板 and the base.

For uneven surfaces, appropriate treatment is required, such as using cement mortar to level the area, ensuring smooth installation of the采光 boards.

3. Installation Process

Cutting Requirements:

When cutting polycarbonate sheets, use a sharp craft knife as the cutting tool. Ensure the cut is flat and smooth, avoiding burrs or cracks. Burrs and cracks can become stress concentration points, easily leading to crack propagation during use.

Cut sizes must be precise, and operations should be based on the actual installation location and size requirements. If the cut light panel sizes are not suitable, it will affect the installation progress and overall effect.

Joint Treatment:

The lapping of the light panels is a critical step. The length of the longitudinal lap should be determined based on the roof slope and local climate conditions, generally not less than 200mm. This ensures that rainwater can drain smoothly and prevents backflow.

Ensure at least one wave peak overlaps during horizontal lap joints, and seal the lap with sealing tape or adhesive. Apply the sealing material evenly to fill the lap gap, preventing rain and dust from entering.

Fixed Method:

The installation of skylight panels should be secure yet not overly tight. Generally, fixed components like aluminum alloy strips or stainless steel screws are used. The spacing of the screws should be reasonable, typically fixed at the crests of the panels. The spacing is determined by the thickness and size of the skylight panels, as well as factors like wind and snow loads, usually not exceeding 300 to 500mm.

When tightening screws, use washers to distribute pressure and prevent the screws from directly pressing on the light-transmitting panel, which could cause localized deformation or damage. Additionally, the head of the screws should not protrude too much above the surface of the light-transmitting panel to avoid affecting its flatness and aesthetic appearance.

4. Safety Precautions

Personal Protection:

Installation personnel must wear appropriate personal protective equipment, such as hard hats, safety shoes, and gloves. Hard hats protect the head from injury by falling objects; safety shoes prevent the feet from being pierced by sharp objects; gloves safeguard the hands to avoid cuts from the edges of the lighting panels during handling and installation.

Fall Protection Measures:

If installation is taking place at elevated levels, such as on rooftops, reliable fall protection measures must be in place, such as installing safety lines and constructing sturdy scaffolding. The safety line should be securely fastened to a solid structure and the length should be appropriate to provide installers with sufficient maneuvering space during operations, while effectively preventing fall accidents.
