At Insulation Board, we take pride in offering our best price on 120mm Celotex as well as express delivery. It has never been easier to order insulation. Simply add your boards to your cart and checkout in minutes. Save the hassle of having to pick up your Celotex 120mm boards and have them delivered directly to your project when it suits you. 120mm Celotex boards are manufactured in accordance with quality management systems (BS EN ISO 9001:2000) and are very versatile. These boards can even be combined with plasterboard. When ordering 120mm insulation boards, it’s crucial to have a clear understanding of your requirements before finalising your order. Taking this proactive approach can help you avoid potential delays in your project. To accurately determine the quantity of 120mm Celotex boards needed for your project, it’s essential to calculate the required area. This calculation involves multiplying the height by the width of the area where you intend to apply the insulation. For instance, if the dimensions of the space are 3m by 3m, the total area would be 9m2. It’s worth noting that each 120mm Celotex insulation board covers an area of 2.88m2. Using this information, consider an example where the area you’re insulating measures 9m2. In this case, you would need a minimum of 4 boards to cover the area. However, as a recommendation, it’s wise to order a slightly larger quantity than the minimum required to accommodate for potential wastage. This allows for unforeseen adjustments during installation and ensures that you have a sufficient supply to complete the project with precision. By carefully assessing your project’s dimensions and factoring in wastage, you can make a well-informed order, which is perfectly aligned with your requirements. This foresight contributes to a smoother and more efficient project execution.

Installing Celotex Insulation Board

The installation of Celotex boards is designed to be hassle free. Below is a quick guide on how to do this, however we do advise you consult a professional. Before you begin, ensure the area is prepared. This includes clearing away debris or obstacles that may hinder the process. You should be wearing appropriate PPE for safety reasons.
Firstly, Begin by measuring the specific area where you intend to install the Celotex insulation boards. These measurements serve as a guide for accurate cuts. Use a measuring tape to obtain precise dimensions. Once measured, transfer these dimensions onto the Celotex boards, marking the areas to be cut. Cut using a saw and ensure the cuts are clean.
The application type will alter the installation method. For example, masonry partial fill cavity wall installations will require mechanical fixings where as upgrading solid walls could be achieved using the dot and dab method. This would feature the use of adhesive. We advise that you check the manufacturer guide at this step. After the Celotex boards are in place, inspect the installation for any gaps between the boards or at the edges. To prevent heat loss and maintain thermal efficiency, you could use insulation tape or sealant to seal these gaps. Depending on the application, you could also add an additional covering layer such as plasterboard at this stage. Once installed, ensure that you inspect and quality check the work as well as clean up any adhesive residue or debris. Lastly, store any unused Celotex insulation boards in a dry and safe location. Proper storage helps preserve the quality and performance of the insulation. If you are looking for 120mm insulation board, we can help.
