Loft boarding

The benefits of boarding your loft
A fully boarded loft offers a wide range of long-term advantages for homeowners looking to make the most of their space. Professionally installed, stable loft boarding can help you:
- Tidy, transform, and declutter your home
- Create a practical and accessible storage area
- Add value, comfort, and functionality to your property
When combined with soft, non-itch, and mould-resistant insulation, your loft becomes not just more usable – but more energy-efficient too. This helps reduce heat loss, lowers your energy bills, and increases your home’s overall comfort.
While other storage solutions can be costly, loft boarding is a cost-effective investment that pays off in both usability and long-term savings.

Using premium boarding
At Viridian, we use high-quality 18mm OSB tongue-and-groove loft boards that provide a strong, stable, and secure flooring solution. At 325mm x 1220mm, these interlocking strong loft boards are ideal for lofts with limited space or smaller hatches. This ensures a smooth installation process without the need for structural alterations.
To support the loft boarding, we install durable timber CLS battens, and beneath these, we fit 100mm PIR insulation. This method not only maintains a consistent air gap for proper ventilation but also helps ensure uniform thermal resistance across your loft floor – essential for maintaining energy efficiency.
Our comprehensive Silver and Gold insulation packages have been designed to transform your loft and give it a fresh, new start. Not only do they offer exceptional value for money, but the loft boarding cost is included in the package price!
If you choose our Platinum Package, our experienced surveyor will assess your loft during the initial visit and recommend the most suitable boarding and insulation solution tailored to your home’s needs.

Following a professional boarding process
At Viridian, we follow a carefully planned and professional installation process to ensure your loft is boarded to the highest standard – safely, efficiently, and with minimal disruption to your home.
Before any work begins, our team will walk you through the full installation plan, answering any questions and confirming that everything is aligned with your expectations. We also take extra care to protect your home, laying down protective coverings all the way to your loft hatch to safeguard your flooring and maintain a clean workspace.
Once everything is prepared, we begin by installing our durable CLS timber battens. These form a strong base and create a vital air gap above the insulation to allow proper ventilation and avoid compromising the effectiveness of the material. Next, we securely fit the tongue-and-groove OSB loft boards, which are carefully screwed into place to prevent movement and ensure long-lasting stability and durability.
This step-by-step loft boarding process is designed to provide you with a safe and accessible storage space that complements your insulation and enhances your home’s energy efficiency.

Benefits of using a certified loft boarding company
Hiring a professional loft boarding company like Viridian comes with a range of advantages that ensure your loft transformation is completed to the highest standards – safely, efficiently, and at a competitive price.
Certified Workmanship: All our loft installations are completed by fully trained and certified specialists, ensuring every step – from the installation of the OSB boards to final checks – is carried out with precision. We follow strict safety protocols and industry standards, giving you peace of mind that the work is both compliant and built to last.
Value For Your Money: DIY loft boarding may seem cheaper at first, but the reality is often different. When you consider the loft boarding cost, tools, and your own time, doing it yourself can quickly become an expensive, frustrating, and possibly unsafe experience. By choosing a professional loft boarding company, you’re investing in high-quality results, long-term durability, and saving yourself a lot of hassle.
Quality Control: Every job we complete goes through a thorough post-installation inspection. Our onsite team ensures that all loft boards are fitted safely and securely, and that the final result is aligned with Viridian’s Gold Standard. That’s our unshakeable commitment to premium quality and customer satisfaction.
