The Installer Advantage: Eliminating Seal Shear

Low-cost flat glass rooflights typically carry a major structural risk: inconsistent sealant application leading to seal shear and water leakage as temperatures fluctuate. The Korniche FlatLite™ eliminates this headache entirely with a smart, repeatable installation system.

Striking Frameless Aesthetic

Designed with a sleek, minimalist exterior profile and no internal framework intrusion, the FlatLite™ allows a completely unobstructed view of the sky. This maximizes day illumination while completely hiding bulky structural framing beneath standard internal plaster lines.

High-Performance Triple Weather Seals

Built to survive the toughest British downpours, the frame incorporates an advanced triple weather seal layout. Tested rigorously to premium standards, it delivers exceptional durability

  • Air Leakage Protection: 600 Pa (Class 4)
  • Weathertightness Security: 600 Pa (Class 9A)
  • Wind Load Resistance: 1600 Pa (Class C4)

PAS24:2022 Security Protection

Security is never an afterthought. Despite its highly competitive price point, the FlatLite™ achieves full PAS24:2022 high-security certification as standard, introducing an advanced structural barrier that guards against forced entry and potential threats.

Optional Ceramic Edge Border

Tailor the final look to match your budget. Choose a standard gloss black ceramic edge border to flawlessly conceal the outer structural sealant lines for a refined, tidy look, or choose a plain glass border on non-overlooked projects to drive costs down further.
