The SL-20 FRP Aluminum Flush Door is constructed as tough as the SL-17, but with a softer, smoother appearance.
The Special-Lite® SL-20 FRP Door is strong, yet aesthetically pleasing with its exclusive, exterior-grade sandstone-textured FRP surface finish. Tough enough for your entire high traffic exterior entrance locations, but also attractive enough to complement indoors spaces. The SL-20 has the same durable construction as the SL-17 for long life and low maintenance and is available in many prominent architectural through-colors.
Features and Benefits
At the Core of our Door’s Strength is our Door’s Core
The poured-in-place urethane core of our SL-20 is not just a passive filler — it’s a functional component that contributes significantly to the durability of Special-Lite® Doors. After the door has been completely assembled, the core material is injected using our proprietary foam injection technology, ensuring a complete fill with a minimum five pounds per cubic foot density.
This strong, lightweight, structural urethane foam bonds firmly to the rails, stiles, reinforcements and face sheets to transform the door into a solid, completely sealed unit with incredible impact resistance and flexural strength. Our urethane foam won’t absorb or be damaged by water.
The SL-20 FRP Door features an aesthetically pleasing, fine-grained surface finish. This door withstands high traffic, improves security and increases energy savings. Building types include public buildings, schools, universities, dorm rooms, government, and restaurants, hotels, healthcare, fitness and sports buildings.
