HD Roof Slab

Optimal Heat Insulation and Compressive Strength for Roofing

HD Roof Slab

The Saudi Rockwool HD Roof Slab, a high-density insulation solution, is crafted from natural basalt rock fibers spun into fine threads and bonded with a thermosetting binder. Oriented to offer exceptional compressive strength, this product is specially designed for use in roofing applications, ensuring structural roof decks are insulated against heat effectively. Adhering to the ASTM C726 standard for mineral fiber roof insulation boards, the HD Roof Slab sets the benchmark for quality and performance in building construction.


Key Applications:

Primarily deployed for heat insulation above structural roof decks, the HD Roof Slab serves as an essential base for built-up roofing systems in both commercial and residential buildings. Its compatibility with all waterproofing membranes and resistance to rot and fungi promote a durable and long-lasting roofing solution.


Installation Ease and Advantages:

  • High Thermal Insulation: Keeps buildings cooler in summer and warmer in winter, enhancing energy efficiency.
  • Excellent Fire Safety: With a Euro fire classification of A1, it provides peace of mind through superior fire resistance.
  • Acoustic Improvement: Boosts the acoustic impact insulation class (IIC) of roofing, contributing to a quieter indoor environment.
  • Durability: Its high compressive resistance and stable physical properties ensure longevity and reliability.
  • Ease of Installation: Designed for straightforward laying and cutting, facilitating a seamless application process.


Facing Options:

Available without facing or optionally with one or two sides faced with materials like aluminum foil or bitumen paper, offering additional protection and versatility. Special facing options can be accommodated upon request, tailoring the product to specific project needs.


Technical Excellence:

Featuring thermal conductivity rates of 0.036 - 0.038 W/m K at 35°C and impressive compressive and tensile strengths, the Saudi Rockwool HD Roof Slab guarantees top-tier insulation performance. Its water absorption volume is below 1%, ensuring the insulation remains effective over time.


Packaged in polyethylene shrinkage bags for optimal protection, the HD Roof Slab is available in a variety of dimensions, densities, and thicknesses, with the possibility of producing other sizes on special order. This flexibility allows for customized insulation solutions, ensuring that every roofing project benefits from the unmatched quality and performance of the Saudi Rockwool HD Roof Slab.
