LAMILUX Modular Glass Skylight MS78

New product: The pre-glazed single tier mono-pitch rooflight


The LAMILUX Modular Glass Skylight MS78 is the newest innovation from LAMILUX which combines all of the advantages of the LAMILUX Glass Skylight FE and the LAMILUX Glass Roof PR60 to bring you a pre glazed single tier mono-pitch rooflight. The thermally broken, mono-pitch rooflight can be configured by forming a row of pre-fabricated modules, presenting design flexibility within product that is easy to specify and install. The official market launch of the Modular Glass Skylight MS78 by LAMILUX is coming soon to the UK. Then, customers will be able to order the modular glass roof system and benefit from its numerous advantages. Until then, full specification of the new system is available by contacting us at sales(at)lamiluxskylights.co.uk or calling 01284 74905

Features and benefits


• CE marked quality according to EN 14351 with CE Label product declaration

• Factory production and office management approved to ISO 9001:2015, which means the quality skylights are manufactured to a consistently high standard

• Pre-fabricated modules  - producing a superior quality rooflight system that reduces on-site installation time

• Enhanced isothermal characteristics in the overall construction – resulting in achieving maximum energy efficiency and thermal insulation


• Thermally broken aluminium framed skylight free of thermal bridges saving heating costs

• Can be configured by forming a row of pre-fabricated modules with no restrictions on fixed / opening configurations

• Opening modules are uniformed in appearance with concealed cables, with no visual difference on fixed modules

• Maximum module size of 1.3m x 3m, and a total rooflight length of up to 20m


• High daylight incidence with a light Transmittance value of 80% (reference double glazed)

• Effective acoustics and soundproofing with a sound insulation value of Rw,p 38dB (reference double glazed)

• For optimum privacy and sun protection optional interior roller shading system reduces glare, solar radiation and heat build-up in the interior    

• Pleasant indoor climate thanks to bespoke configuration of as many individual modules opening for daily ventilation as your project requires


• Suited for application for many sectors within commercial and public buildings 

• Ideal for installation in wood, concrete or steel substructure with pitch inclinations ranging from 5° - 30°

• Improving performance and well-being, due to daylight, optional ventilation and sun and glare protection

Design flexibility

The latest daylighting innovation from LAMILUX offers design freedom with installation available in substructure pitch inclinations ranging from 5° - 30°, and many size configurations - with a maximum module size of 1.3m x 3m, and a total rooflight length of up to 20m. Each module, whilst uniformed in appearance, can be configured as a fixed panel, or as an integrated opening vent for natural ventilation with no restrictions on fixed / opening configurations - removing any requirement for fixed modules in between opening modules

Design details

Modular Glass Skylight MS78 technical design characteristics

Energy efficiency

The Modular Glass Skylight MS78 is a thermally broken single tier mono-pitch rooflight that can be configured by forming a row of modules giving both design flexibility alongside a high performance rooflight system. The aluminium profiles coupled with a  glazing system boasting maximum energy efficiency and thermal insulation ensures certified high levels of wind and rain resistance, alongside enhanced isothermal characteristics in the overall construction. The unrivalled performance of this range results in no condensation alongside excellent air tightness values. 

Interface and fitting

Specialist installation service available subject to our standard installation terms.

Mounting direction: From left to right. 

Self-aligning module connection with tongue and groove principle ensures:

•    Easy assembly

•    Self-aligning due to V-groove

•    Drainage profile


•    CE marked quality according to EN 1873
•    Life Cycle Assessment (LCA) to EN 15804
•    Airtight to Class 4, EN 12207
•    Water tightness tested Class 4 according to BS EN 12208
•    Wind Load to Class C5, EN 12210
•    System U-value: Double Glazed Thermal transmittance of glazing system:
      Ug approx.1.1 W/m²K. Uw 1.0-1.5 W/m²K 

Quality control of component manufacture: 

•    Energy management system to EN ISO 50001:2011
•    Quality management system to EN ISO 9001:2015  

Isothermal line diagram:  

The thermally broken “isothermally balanced” aluminium frames feature optimally aligned 10° isotherm line. This means that the thermally broken 10° isothermal line remains within the structure.
