What’s the difference between bi-fold and sliding doors offered by Klassic Trade Frames?

Bi-fold doors fold neatly to create wide openings and seamless garden access, while sliding doors glide open with expansive glass panels for uninterrupted views and smooth transitions between indoor and outdoor spaces.

What types of sliding doors can I choose from?

You can select from three styles: Traditional Patio Sliding Doors for classic spaces; Multi Slide Doors for flexible, wide openings; Lift & Slide Doors for luxury homes needing superior sealing and effortless operation.

What glass options are available for bi-fold and sliding doors?

All doors come with toughened glass as standard. You can also request laminated glass for added safety and acoustic insulation, float glass for clear views, or Pilkington decorative and performance glass for privacy, energy efficiency, or custom design features.
