Replacing UPVC glass can be a rewarding DIY project, but it's essential to know when it's best to call in a professional. Whether you're looking to improve insulation, fix a cracked pane, or update your home's appearance, understanding the process can save you time and money.

Understanding UPVC Glass

UPVC, or unplasticized polyvinyl chloride, is a popular choice for window frames due to its durability, low maintenance, and energy efficiency. Before diving into a DIY project, it's crucial to understand how UPVC frames work and how to handle them properly.

  • Glazing tape or silicone sealant
  • Measuring tape
  • Putty knife
  • Screwdriver
  • Safety gloves and goggles
