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.

Sub flooring is the structural layer beneath the finished floor, designed to provide strength, stability, and a smooth surface for materials like tiles, carpet, or parquet. It distributes weight evenly and prevents flooring failures. Traditionally made from plywood or MDF, sub flooring materials must be durable and climate-resistant. DesertBoard’s Palm Strand Board (PSB®) is engineered for these purposes, offering termite resistance, dimensional stability, and carbon-negative sustainability. This makes it a superior choice for sub flooring in residential, commercial, and hospitality projects.

Durable sub flooring is critical because it prevents warping, cracking, or sagging that can compromise finished floors. Poor-quality materials often lead to costly repairs or replacements. In humid climates like the GCC, durability becomes even more important, as moisture and termites quickly damage MDF and chipboard. DesertBoard PSB® solves this with engineered strength and built-in resistance to environmental stressors. Its durability ensures long-term performance, lower lifecycle costs, and healthier, zero-formaldehyde indoor environments.

Sub flooring contributes to acoustic insulation by reducing sound transmission between floors. It also enhances comfort by creating a solid, level surface underfoot. Traditional boards can lose integrity over time, leading to squeaks or uneven surfaces. DesertBoard PSB®’s dense composition improves acoustic performance while maintaining strength, making it ideal for apartments, hotels, and offices. Its carbon-negative, zero-formaldehyde credentials add sustainability to comfort, ensuring better living and working environments.

Plywood, MDF, and OSB are the most common sub flooring materials. Each has trade-offs: plywood is strong but costly, MDF is affordable but moisture-sensitive, and OSB offers mixed durability. DesertBoard PSB® provides a new alternative by combining durability with eco-credentials. Made from upcycled palm fronds, it is carbon-negative, termite-resistant, and suitable for GCC climates. For developers seeking sustainable sub flooring without compromising performance, DesertBoard is a next-generation solution.

Moisture is one of the biggest threats to sub flooring, causing swelling, warping, or mold growth in materials like MDF and plywood. This is especially problematic in humid regions or areas with frequent spills. DesertBoard PSB® is engineered for resilience, maintaining dimensional stability when coated for moisture protection. Its durability makes it well-suited for kitchens, bathrooms, and commercial spaces where moisture exposure is common. By resisting water damage, DesertBoard ensures long-lasting flooring systems.

Yes. Sub flooring can play a role in thermal insulation, especially when integrated with underlayment or insulation layers. This reduces energy use by minimizing heat transfer between floors. DesertBoard PSB® contributes to energy-efficient designs by providing a dense, stable base that supports insulation layers effectively. In addition, its carbon-negative production reduces embodied energy, aligning with projects aiming for LEED, WELL, or Estidama certifications. This dual impact makes DesertBoard both practical and sustainable for energy-conscious construction.

The lifespan of sub flooring depends on the material. MDF may last less than a decade in humid conditions, while plywood can extend to 15–20 years with maintenance. DesertBoard PSB®, designed for GCC climates, offers a much longer service life due to termite resistance and dimensional stability. Its durability reduces the need for frequent replacements, lowering lifecycle costs. For developers, this means reliable long-term performance and a reduced environmental footprint through fewer material changes.

Sub flooring is typically installed over joists or slabs using nails, screws, or adhesives. It must be level and securely fastened to prevent squeaks and uneven floors. DesertBoard PSB® is fully machinable and works with conventional installation methods, making it easy for contractors to adopt. Its superior screw-holding strength ensures tight, lasting connections. This practicality, combined with eco-friendly credentials, makes DesertBoard a seamless upgrade from conventional sub flooring materials.

Costs vary: MDF and chipboard are cheap upfront but prone to failure, while plywood is stronger but more expensive. DesertBoard PSB® sits competitively in the mid-range but offers far better lifecycle value. Its durability reduces replacement frequency, and local production lowers shipping costs compared to imports. When sustainability benefits and certification contributions are considered, DesertBoard provides both economic and environmental advantages, making it cost-effective over the long term.
