OSB Loft Boards

(1 Product)

OSB loft boards are a fascinating and ingenious invention that has revolutionised the world of construction and home improvement. These engineered wood panels are made from oriented strand board, which consists of thin strands of wood that are glued together under high pressure and temperature to create a strong and stable surface. At first glance, OSB loft boards may seem unremarkable - just another building material among countless others. But upon closer examination, their true value and versatility become clear. These boards can be used to create loft storage spaces or attic floors, providing an additional level of usable space in homes and buildings.

What Are OSB Loft Boards?

Oriented strand boards (OSB) are a type of engineered wood panel typically used as a cost-effective and convenient solution for creating a loft storage space or an attic floor.

But what exactly is an oriented strand board? Picture a puzzle made from wood chips that have been oriented in a specific direction, and then bonded together with a resin binder under high pressure and temperature. The result is a durable, smooth and stable board that is easy to handle and install.

Although they might not be the most glamorous building material around, OSB loft boards definitely have their place in the DIY world. They're strong, lightweight, and able to support heavy loads without sagging or warping.

But the benefits of OSB loft boards extend beyond their physical properties. They're also an environmentally friendly choice, as they're made from fast-growing and sustainably sourced wood species. And because they're relatively inexpensive compared to other flooring materials, they're accessible to a wide range of people and budgets.

Tips for Installing OSB Loft Panels

If you're planning to install OSB loft boarding in your home, here are a few tips to keep in mind:

  • Measure twice, cut once: Make sure to measure the space carefully before cutting your boards to size. You don't want to end up with boards that are too short or too long for the space.
  • Use the right tools: You'll need a saw or circular saw to cut your boards to size, as well as a drill and screws to secure them in place.
  • Follow the manufacturer's instructions: Make sure to follow the manufacturer's instructions/graphic instructions carefully when installing your OSB loft boards. These guidelines tend to have health and safety hazards covered; this will ensure that they're installed correctly and safely.

OSB Tongue & Grooved Panels

These tongue and groove OSB loft boards comprise a ‘tongue’ edge with a precisely engineered gap ‘groove’. When installing the boards, this tongue edge slots perfectly into the groove, making the installation process a breeze.

OSB Loft Board Storage and Handling

Proper storage and handling are crucial to maintaining the integrity of OSB (Oriented Strand Board) loft boards and preventing damage. Follow these guidelines to ensure the safe storage and handling of your OSB loft boards:

  • Storage: Store OSB loft boards in a dry, well-ventilated area on a flat, level surface. Avoid direct contact with the ground or concrete. Use protective covers if storing outdoors.
  • Handling: Handle loft boards carefully to prevent damage to edges and surfaces. Use proper lifting techniques and equipment to avoid strain or injury. Avoid dropping or dragging boards during transportation.
  • Protection: Shield boards from exposure to moisture, sunlight, and heavy objects during storage. Prevent stacking heavy items on top to avoid crushing or deformation.
  • Acclimatisation: Allow boards to acclimate to the installation area's temperature and humidity for at least 48 hours before installation to minimise dimensional changes.
  • Inspection: Before installation, inspect OSB loft boards for any damage. Reject any boards that do not meet quality standards to ensure successful installation.
  • Storage Duration: Avoid prolonged storage, especially in outdoor or exposed environments, to minimise the risk of moisture damage and degradation over time. Use boards within a reasonable timeframe.

Frequently Asked OSB Loft Boards Questions

Can OSB Loft Boards Be Painted or Stained?

Yes, OSB loft boards can be painted, stained, or left unfinished depending on your preference.

Are OSB Loft Boards Environmentally Friendly?

Yes, OSB loft boards are an environmentally friendly choice. They're made from fast-growing and sustainably sourced wood species.

How Are OSB Boards Graded?

European standards dictate four distinct grades of OSB board, each denoting the strength and moisture resistance levels of the product.

  • OSB1: Specifically designed for furniture construction and other dry indoor projects.
  • OSB2: Load-bearing properties, to be used solely in dry conditions.
  • OSB3: Load-bearing properties, suitable for use in humid environments.
  • OSB4: Engineered to have a higher load-bearing capacity and greater resistance to moisture than other grades of OSB - ideal for use in challenging and humid environments.

What Are Zero Added Formaldehyde OSB Loft Boards? 

Designed with environmental sensitivity in mind, Zero Added Formaldehyde Panels are ideal for uses such as museums and art galleries - but can also be used in places like hospitals, schools, care homes and other public buildings. 

To ensure they meet the highest standards of safety and reliability, these panels have undergone rigorous testing processes.

It is essential to be aware of the fact that low levels of formaldehyde are already present in wood and, therefore, its derivatives. These concentrations are so minuscule however that they don't pose any immediate risk - much like a forest or other green spaces have natural emission rates. 

The issue arises when resins used for wooden panelling inflate these figures beyond what is naturally safe.
