Best Practices.

To ensure optimal performance in humid conditions, it is recommended to apply a coating to the boards. This will enhance their durability and resilience against moisture, thereby maintaining their reliability in load-bearing applications.

When resizing the boards (cutting to different or smaller dimensions), it is essential to coat the newly exposed edges.

For components being fastened, such as beams, rafters, joists, and trusses, pre-drilling is essential. The diameter of the pre-drilled hole should be smaller than the screw diameter to ensure effective engagement of the screw threads.

During transportation and storage, it is important to protect the PSB® boards from direct exposure to water droplets and precipitation on their edges and surfaces. Ensure that adequate protective covers are provided to maintain their integrity.

For fastening, it is recommended to use screws, nails, or staples with a length at least 2.5 times the thickness of the board, but not less than 50-75 mm. Fastening should be carried out at intervals of 150-300 mm on intermediate supports (depending on roof pitch), 150 mm along board joints, and 100 mm along roof edges.

It is advised not to install decorative tiles or wallpaper directly on PSB® Supreme, nor should plaster work be applied to its surface.

FAQs.

Substrate boards form the base layer in roofing systems, providing strength, stability, and a secure surface for membranes, insulation, or tiles. Without a proper substrate, roofing layers can shift, crack, or fail under load. In the GCC, this is especially important because of heat, humidity, and wind loads. DesertBoard’s Palm Strand Board (PSB®) is engineered to deliver reliable performance as a roofing substrate, offering termite resistance, dimensional stability, and carbon-negative sustainability, making it a better choice than plywood or MDF.

The choice of roofing substrate and surface material impacts durability, energy efficiency, and maintenance costs. Poor-quality substrates may warp or degrade, leading to leaks and structural issues. DesertBoard PSB® offers superior stability, supporting insulation and coatings effectively, which helps regulate indoor temperatures and reduces cooling loads in GCC climates. Unlike MDF or chipboard, DesertBoard is resistant to termites and environmental stress, ensuring roofing systems perform reliably while contributing to sustainability goals.

Roofing systems use a combination of structural decking, insulation, waterproofing membranes, and surface finishes. Substrate boards are often plywood or MDF, though both can degrade in hot, humid environments. DesertBoard PSB® provides a sustainable alternative, engineered from upcycled palm fronds. It is carbon-negative, zero-formaldehyde, and resistant to termites, making it well-suited for GCC climates. Its durability reduces the risk of failures, offering developers a modern material that balances sustainability with high performance.

Extreme climates with high heat, humidity, and UV exposure shorten the lifespan of traditional roofing materials. Timber substrates warp, while MDF swells and loses strength. DesertBoard PSB® is engineered to withstand GCC conditions, maintaining stability under heat stress and resisting termite damage. When coated, it performs reliably even in coastal environments. By choosing DesertBoard, contractors ensure longer-lasting roofing systems with fewer replacements, lowering both costs and environmental impact over a building’s lifetime.

Yes. Roofing plays a major role in thermal regulation, especially in hot climates where most energy use goes toward cooling. Substrate boards like DesertBoard PSB® provide strong support for insulation layers and reflective coatings, helping reduce heat transfer into the building. This lowers air conditioning demand and operational costs. Because DesertBoard is also carbon-negative, it not only reduces ongoing energy use but also cuts embodied carbon, aligning with LEED and Estidama sustainability goals.

Roofing systems can last anywhere from 15 to 40 years depending on the materials, installation quality, and maintenance. Substrate durability is critical—if the base layer fails, the entire system is compromised. DesertBoard PSB® is designed for longevity, offering dimensional stability, termite resistance, and resilience against GCC heat and humidity. Its durability ensures roofing systems last longer and require fewer replacements, making it a cost-effective and environmentally responsible choice for developers and contractors.

Waterproofing membranes rely on stable, secure substrates. If the board beneath shifts or swells, membranes can tear or lose adhesion, causing leaks. DesertBoard PSB® provides a dense, stable base that resists swelling and warping when coated, ensuring waterproofing layers remain intact. Compared to MDF or chipboard, which degrade quickly in humid environments, DesertBoard offers far superior reliability. This makes it ideal for roofing applications where waterproofing integrity is critical to long-term building performance.

MDF and chipboard are cheaper upfront but fail quickly in hot, humid, or pest-prone climates, leading to high replacement costs. Plywood performs better but is often expensive and carries high embodied carbon. DesertBoard PSB® offers a balanced solution—competitively priced, locally manufactured, and longer-lasting. Its durability lowers lifecycle costs, and its carbon-negative production enhances ESG reporting. For developers, DesertBoard is a practical and sustainable investment compared to traditional substrates.

Roofing materials affect both operational energy and embodied carbon. Traditional timber and plywood may involve deforestation and high transport emissions. DesertBoard PSB®, manufactured locally in Abu Dhabi, uses upcycled palm fronds, avoiding deforestation while sequestering carbon. It supports insulation and reflective coatings, improving operational energy efficiency. This dual contribution—reducing both embodied and operational carbon—positions DesertBoard as one of the most sustainable roofing substrate options available in the GCC.

Yes. While most projects still use plywood or imported composites, sustainable alternatives like DesertBoard’s Palm Strand Board (PSB®) are increasingly available in the region. DesertBoard is carbon-negative, zero-formaldehyde, termite-resistant, and engineered for the GCC’s extreme climate. It provides durability and sustainability without compromising performance, making it a standout choice for developers and contractors. By specifying DesertBoard in roofing, projects benefit from long-term performance, reduced maintenance, and stronger sustainability credentials.

DesertBoard’s Palm Strand Board (PSB®) is engineered from upcycled date palm fronds, making it a carbon-negative and deforestation-free alternative to traditional plywood and MDF roofing substrates. It is zero-formaldehyde, contributing to healthier environments while offering durability, termite resistance, and fire ratings up to 90 minutes. In roofing applications, PSB® delivers strength, machinability, and long-term stability even under the GCC’s extreme conditions. By choosing DesertBoard, developers can reduce embodied carbon while achieving performance and sustainability in their roofing projects.

Yes. DesertBoard PSB® can be used in both flat and pitched roofing systems as a strong substrate or structural support board. Its machinability makes it compatible with roofing membranes, insulation layers, and protective coatings. When properly sealed, it resists moisture and thermal stress, ensuring long-term reliability. Unlike traditional plywood, which often warps or swells, DesertBoard maintains dimensional stability. This makes it a versatile option for diverse roofing applications in residential, commercial, and industrial projects across the GCC.

oofing materials in the GCC must endure intense heat, humidity, and UV exposure. DesertBoard PSB® is engineered with these factors in mind. It maintains stability under thermal stress, resists termite infestation, and performs reliably when coated for moisture protection. Unlike MDF or low-grade plywood, which can deteriorate in harsh weather, DesertBoard provides long-term performance. This resilience reduces repair and replacement costs, making it a practical and sustainable roofing solution for the Middle East.

Plywood and MDF are widely used in roofing but often degrade under humidity, pests, or extreme heat. They may also release formaldehyde into indoor spaces. DesertBoard PSB® is carbon-negative, zero-formaldehyde, and stronger in screw-holding and machinability. It resists termites and maintains stability in the GCC climate, where traditional boards often fail. By offering both sustainability and performance, DesertBoard provides a superior alternative that enhances safety, durability, and environmental responsibility in roofing systems.
