  • Creating an access panel in a drywall ceiling is a practical solution for maintaining and inspecting plumbing, electrical wiring, or HVAC systems hidden above your ceiling. Whether you’re a DIY enthusiast or someone looking to save on professional labor costs, this guide will walk you through the steps to make an access panel safely and efficiently.


  • One of the standout features of mineral fibre board insulation is its exceptional thermal performance. The product provides high resistance to heat flow, which helps maintain stable indoor temperatures and reduces energy consumption for heating and cooling. This can lead to significant cost savings for homeowners and businesses alike, as well as a smaller carbon footprint. The thermal resistance of mineral fibre boards is measured using the R-value, with higher values indicating better insulating properties.


  • Cost is another important factor to consider. Generally, gypsum ceilings are more affordable in terms of initial material costs compared to PVC panels. However, when factoring in installation labor and maintenance expenses over time, the overall cost can balance out. PVC ceilings might have a higher upfront cost, but their durability and low maintenance can lead to savings in the long run.
