About ProRox® SL 550
ProRox SL 550 is a strong, rigid stone wool insulation slab designed to bring effective insulation to industrial applications subjected to mechanical loads, such as tank roofs. While tank roof insulation is often overlooked due to, among other things, corrosion risks, significant heat loss can occur without proper insulation. ProRox SL 550 addresses this challenge with its excellent thermal and acoustic performance and high compressive strength, making it suitable where foot traffic or mechanical loads are present.
- Water repellent to minimise the risk of CUI
- Non-combustible and fire resistant
- Uniform appearance – easy to handle and cut-to-size on site
Application
Purpose-built and optimised for the temperature range 10°C to 250°C for insulating tank roofs and similar areas exposed to foot traffic. Provides reliable thermal and acoustic performance under demanding conditions.
