Normal and regular maintenance is required to maintain the appearance and extend the finish life and maintain proper operation. The following maintenance procedures are recommended.

Tracks and Bearings- Remove surface contaminants by wiping visible track surfaces with a damp soft cloth and a mild detergent, then wipe dry with a clean cloth. Use a suitable applicator to spread a small amount of clear petroleum jelly or similar lubricant. Ensure that the carrier wheels pass through the lubricant so that it is distributed evenly along the tract. Place additional lubricant around the bearings. In severe environments, apply a thin firm of WD40. Always keep the bottom guide channel free from debris.

Aluminum Coating- Exposed surfaces should be cleaned with mild detergent soap and water. Any chips or scratches must be repaired immediately and not left exposed to the elements.

Screen- Dust and debris can collect in the guide channels over time. Removal of such build up is easy and important to the screen’s smooth movement. While the screen is retracted, remove any debris with a soft cloth or a vacuum cleaner with a soft brush nozzle. Dusty or coastal environments will require regular cleaning. The screen mesh should be lightly dusted to maintain an unobstructed view and air flow. While the screen is extended, remove any build up with a vacuum cleaner with a soft brush nozzle, care should be taken not to tear or rip the mesh.

NFRC is a condensation rating that manufacturers can include on their labels. It shows testing results of the U-Factor, Visible Transmittance, Solar Heat Gain Coefficient, and Air Leakage.

  • U-factor gives the rate of heat transfer through the window-from inside to outside when it is cold and from outside to inside when it is hot. The lower the U-factor, the better the insulating properties, resulting in greater energy efficiency. Range: 0.20-1.20.
  • Visible Transmittance measures how well a product is designed to effectively light your home with daylight, which potentially saves you money on artificial lighting. The higher the number, the more natural light let it in. Range: 0-1.
  • Solar heat gain coefficient (SHGC) is defined when sunlight hits a window and the solar heat is absorbed and subsequently released inward. The SHGC represents the fractional amount of the solar energy that ends up warming the house. The lower the SHGC, the less solar heat it transmits. Range: 0-1.
  • Air Leakage measures how much air will enter a room through a product. The lower the number, the fewer drafts you’ll experience. Range: ≤ 0.3.
