Description

Rockwool HD Roof Slab is a premium insulation board made from molten basalt rocks that are spun into fine fibers and bonded with a thermosetting binder to form rigid slabs. This product is engineered to provide good thermal, fire-resistant, and acoustical properties. Its high compressive resistance of 15-80 kPa makes it ideal for supporting loads on roofing systems. The Roof Slab has excellent thermal conductivity ranging from 0.036 to 0.034 W/m.K at 24°C, ensuring optimal energy efficiency.

The product is non-combustible with the highest Euro Class A1 fire classification, providing ultimate fire safety for building envelopes. Its acoustic performance is also exceptional, with a Noise Reduction Coefficient (NRC) of 1, effectively dampening external noise. Gitco-sa.com offers a complete range of HD Roof Slabs with various densities (120-200 kg/m³) and thicknesses (50-150 mm) to suit specific project needs. The boards are available unfaced or with a variety of facings, including Aluminum foil/PE/Bitumen, to meet different roofing requirements.

Key Applications of HD Roof Slab:

• Flat and Low-Slope Roofs: Provides a durable and fire-safe insulation layer for roofing systems in commercial and industrial buildings.
• Under-Screed Insulation: Used as a rigid base for screed floors to provide both thermal and acoustic insulation.
• Roofed Parking Garages: Its high compressive strength makes it an ideal insulation solution for surfaces that will be subjected to vehicle traffic.
• Terraces and Balconies: Offers a reliable thermal barrier for outdoor living spaces.

Know more about HD Roof Slab:

1. What is an HD Roof Slab?

An HD (High-Density) Roof Slab is a rigid or semi-rigid insulation board made from basalt rock fibers. It’s specifically engineered for use in roofing systems, particularly as a base layer for waterproofing membranes.

2. What makes it a “High-Density” slab?

It refers to a nominal density typically ranging from 120 kg/m³ to 160 kg/m³, which gives it superior physical properties, especially compressive strength.

3. Why is compressive strength important for a roof insulation product?

Compressive strength allows the slab to withstand heavy loads without deforming. This is crucial for flat roofs that must support foot traffic, maintenance crews, HVAC units, or even a built-up roofing system.

4. What is the typical compressive strength of an HD Roof Slab?

A standard HD Roof Slab has a compressive strength of at least 60 kPa, and often much higher, allowing it to resist deformation under pressure.

5. How does it provide heat insulation?

The fibrous structure of the rock wool traps air, creating a thermal barrier that slows down heat transfer. This keeps buildings cool in the summer and warm in the winter, significantly reducing energy consumption.

6. What is its thermal conductivity (k-value)?

The thermal conductivity is very low, ranging from 0.036 to 0.038 W/m·K, indicating high thermal efficiency.

7. Is the HD Roof Slab fire-resistant?

Yes, rock wool is inherently non-combustible. The product has a high melting point, exceeding 1000 °C, and a Euroclass A1 fire rating, which is the highest possible.

8. Does it also offer acoustic benefits?

Yes, the dense fibrous structure is effective at absorbing sound, which helps to reduce external noise from rain, wind, and city sounds, creating a quieter indoor environment.

9. Is it moisture-resistant?

Yes, rock wool is naturally hydrophobic (water-repellent) and does not absorb moisture, which is vital for maintaining thermal performance and preventing the growth of mold and fungi in roofing systems.

10. How is it installed on a roof?

The slabs are typically laid directly onto the structural deck. They are then covered with a waterproofing membrane and sometimes ballasted with gravel or pavers. The slabs are dimensionally stable and easy to cut and fit.

11. Can it be used with all types of roofing membranes?

Yes, HD Roof Slabs are compatible with all common waterproofing membranes, including bitumen, PVC, and EPDM, and act as a stable base for their application.

12. Does it contain harmful chemicals?

No, the product is asbestos-free and does not contain any other harmful substances, contributing to a healthy indoor environment.

13. What are the common dimensions and densities available?

They are typically available in standard sizes like 1.2m x 0.6m and in various thicknesses, with densities ranging from 120 to 160 kg/m³, depending on project requirements.

14. How long does the insulation last?

The slabs are highly durable and dimensionally stable. They do not shrink, settle, or degrade over time, ensuring their thermal and physical properties are maintained for the life of the building.

15. Can it be used in green roofing systems?

Yes, its high compressive strength makes it an ideal base for green roofs, which require a durable and load-bearing insulation layer to support vegetation, soil, and irrigation systems.

16. Does it help with green building certifications?

Yes, by significantly reducing a building’s energy consumption and being made from a natural, abundant resource, it can help projects earn credits for certifications like LEED (Leadership in Energy and Environmental Design).

17. Are there different types of facings available?

Yes, the HD Roof Slab can be supplied with or without a facing. Common facings include bitumen paper or aluminum foil for added protection and vapor control.

18. What international standards does it comply with?

High-quality HD Roof Slabs, such as those from Saudi Rockwool, are manufactured to comply with international standards like ASTM C 726, which specifies requirements for mineral fiber roof insulation boards.

19. Where can one find technical data and purchase this product?

Specialized suppliers like Gitco-sa.com are a key source for these products in the Middle East. They provide detailed technical data sheets and expert advice for project-specific applications.
