U-Trim Edge Sealing Strips

Essential protection for polycarbonate hollow sheets. Prevents dust and water infiltration that damages panel performance and appearance.

Assorted Constructionmart U-shaped profiles in various colors designed for sealing and finishing the edges of hollow twin wall polycarbonate sheets.

Why Edge Sealing is Critical

Unprotected hollow sheet edges are vulnerable to contamination that compromises performance, appearance, and longevity

Dust Infiltration

Problem

Dust particles enter hollow chambers, reducing transparency and creating unsightly appearance

Solution

U-trim seals create complete barrier preventing dust accumulation inside panels

Water Penetration

Problem

Water enters chambers causing algae growth, condensation, and potential material degradation

Solution

Secure edge sealing prevents water infiltration and maintains panel integrity

Thermal Performance

Problem

Open edges compromise insulation properties and allow air circulation in chambers

Solution

Proper sealing maintains designed thermal performance and energy efficiency

The Cost of Unprotected Edges

Performance Issues

  • Reduced light transmission due to dust buildup
  • Compromised thermal insulation properties
  • Visible contamination affecting aesthetics
  • Potential algae and mold growth

Financial Impact

  • Costly panel replacement due to contamination
  • Reduced building energy efficiency
  • Maintenance and cleaning expenses
  • Warranty issues and premature failure

Essential for professional installations

Been installing greenhouses for 15 years and learned the hard way about edge sealing. These PC U-trims are now standard on all our projects. Perfect color match with clear panels, and the installation is straightforward. Customers appreciate that their panels stay clean and clear long-term.

Aluminum U-trims for heavy-duty applications

Used the thick panel aluminum U-trims for a large commercial project with 16mm panels. The build quality is excellent, and they provide superior protection compared to plastic alternatives. The weight gives confidence in the durability, and the professional finish looks great.

Solved our contamination problems

Had ongoing issues with dust and debris getting into our skylight panels, making them look dirty and reducing light transmission. These U-trim seals completely solved the problem. Three years later, the panels still look new. Wish we had used these from the beginning - would have saved money and hassle.

Good quality, packaging could be better

The U-trim quality is excellent and they fit perfectly on our 6mm panels. Installation was easy and they've performed well over the past year. Only minor complaint is that some pieces arrived slightly bent due to packaging, but they straightened out fine during installation. Overall very satisfied.
