Q1: Are Bifold Doors Thermally Efficient?
A1: Yes! Modern bifold doors are highly thermally efficient:

  • Aluminium bifolds: Built with thermal breaks to prevent heat conduction.
  • Glazing: Units filled with argon gas for enhanced insulation.

Q2: What is a U-Value?
A2: A measure of heat loss through a product; lower U-values indicate better insulation.

Q3: How Many Panels Will I Need?
A3: Minimum: 2 panels. For larger setups: Tracks can support up to 8 panels; beyond 20 feet, dual tracks are required.

Q4: Which Way Do Bifold Doors Fold?
A4: Bifold doors are customisable to fold left, right, or split both ways. The lead door placement depends on the configuration you choose.

  • Toughened glass and internal glazing beads.
  • Anti-lift blocks and PAS 24 compliance.

Q8: Why Do Aluminium Frames Cost More Than uPVC?
A8: Aluminium is costlier to produce and requires precision engineering. Powder-coating and thermal breaks also increase manufacturing complexity.
