Frequently Asked Questions
What material is the LB plus rooflight made of?
The LB plus rooflight consists of an aluminum and thermally separated PVC profile system with various polycarbonate glazing options to meet a wide range of requirements, such as protection against heat, noise, and sunlight. A complete list of options can be found in the product data sheet.
Can the LB plus rooflight be combined with roofs made of insulated sandwich panels from Kingspan?
The LB plus rooflight can be used on flat roofs with a maximum roof pitch of 25° and is compatible with all raised roof systems and Kingspan sandwich panels. For a safe and compliant connection, the use of the ZSA corner safety connection is recommended. Examples of installation in Kingspan insulated panel roofs are available upon request.
Can the LB plus rooflight be combined with safety products?
Yes, the LB plus rooflight can be configured with a glazing variant that meets the requirements for a hard roof according to BROOF (t1). Additionally, it is compatible with our fall protection and penetration safety features, providing additional protection for people working on the roof.
What is the difference between the LB plus rooflight and the LB basic rooflight?
The main difference between the LB plus rooflight and the LB basic rooflight is that the LB plus skylight is thermally separated, offering improved thermal performance and low U-values.
Can the LB plus rooflight also be used for smoke and heat extraction and for daily ventilation?
Yes. The rooflight can be installed with full or ridge flaps, which are tested according to EN 12101-2 and suitable for smoke and heat extraction. Contact our technical team to discuss your requirements further.
What sizes is the LB plus rooflight available in?
Due to its modular construction, the LB plus rooflight is available in any length and a width of 1 m to 6 m (depending on the chosen glazing).
For which types of buildings is the LB plus rooflight commonly used?
The LB plus rooflight is well-suited for projects aiming to achieve higher thermal efficiency or exposed to high humidity and condensation risk, such as bakeries, sports halls, and production facilities.
