Artisan offers two distinct roof lantern systems, the S1 and S2, each designed to provide high performance glazing solutions for extensions and orangeries.
The S1 is marketed as a highly secure and thermally efficient lantern with an "ultra-low line" aesthetic.
Design & Aesthetics: It features slim, consistent 50mm sightlines for rafters, hips, and ridges to maximize natural light. The external top caps sit only 8mm above the glass for a sleek profile.
Security: It includes anti-tamper security screws and a patent-pending glass lock. An optional Secured by Design (SBD) upgrade is available, which uses stainless steel clamping plates to prevent the glass from being lifted or removed.
Thermal Performance: The system uses "Thermlock" multi-chamber technology in the eaves, ridge, and rafters, which is designed to be more efficient than traditional polyamide. It also features co-extruded perimeter seals to prevent draughts.
Specifications:
Fixed Pitch: 25°.
Max Size: 3200mm x 6000mm.
Styles: Available in 13 different configurations, including square pyramids.
Extra Features: Integral LED light channels can be built into the ridge and eaves.

The S2 is a versatile system engineered for larger spans and modern glazed extensions.
Versatility: It can accommodate various roof styles and combinations, including larger "grand designs".
Construction: It comes standard with chambered PVC-U cappings for thermal performance, with an optional aluminium capping upgrade for a high-end finish. It also features a "bolster" option to allow for large openings, such as those above bi-fold or patio doors.
Modern Aesthetics: The S2 uses square internal and external cladding for an uncluttered look. The ridge system is low-profile by default but can be upgraded with traditional crestings and finials if desired.
Performance: It is fully thermally broken and designed to prevent glass slippage through specialized glazing security plates.

Sheervent®: Both systems can incorporate this flush-mounted, intelligent ventilation solution. It sits perfectly level with the rafter bars and can be automated with rain sensors and remote controls.
Glass Options: A wide range of high-performance 28mm glazing is available, including self-cleaning glass and various tints (Blue, Aqua, Bronze, etc.) with U-values as low as 0.7 in triple-glazed configurations.
Colours: Lanterns are available in standard colors like Anthracite Grey, Jet Black, and Agate Grey, or they can be customized to any RAL colour in various finishes (matt, satin, or gloss).
