So while flexible systems may be perceived by some as the easier, cheaper option, they will never match the quality, light output and efficiency of a rigid tube system. In continental Europe, flexible systems are shunned owing to their poor performance and quality. In the UK, however, while the professional community rarely specify them, some homeowners and builders are tempted by the big brand name or use them simply because they are readily available at builder’s merchants and are cheap.
If you want a quality, efficient tubular daylighting system that delivers high levels of daylight into your home, make sure you (or your builder!) steer clear of flexible tube systems!
