What Are Plastic Wedge Packers?
Plastic wedge packers are robust, high-density plastic shims designed for accurate leveling, spacing, and load distribution in construction projects. The “3-6mm” refers to their adjustable wedge thickness—providing micro-to-macro alignment in everything from window and door installations to decking, cladding, and more. Proper installation is critical, and choosing the right size of packers can significantly impact the overall stability and precision of your project. Ensuring that the packers fit snugly and provide adequate support will help prevent issues such as settling or shifting over time. By carefully selecting the appropriate thickness, you can achieve a seamless and durable finish in your construction endeavors.

Why Do Professionals (and DIYers) Use Plastic, Not Timber?
While timber shims and makeshift fillers were standard for years, they come with drawbacks: they can rot, compress, and vary in thickness. Plastic wedge packers guarantee:
– Exact sizing on every piece,
– Lifetime resistance to water and insects,
– No swelling, shrinking, or splitting,
– Consistency, every project, every time.
