Leadax is the new lead with the same properties as traditional lead. The basic raw material is unused PVB waste material. This is the residue from the production of laminated glass (e.g. car windows). As a result, it has no harmful effect on health or the environment. Not only is it lighter to use, it is also cheaper to purchase.

Intura Suntube light tunnel for pitched roof type 25
A light tunnel is a system that allows daylight to enter through reflection. The advantage of this system is that only a small roof opening is required compared to, for example, a skylight.
The Intura Suntube light tunnel has a crystal glass dome that allows more light to enter than direct daylight. The dome is self-cleaning, does not yellow and algae or dirt will not adhere to it, so there will be no loss of light over the years.
