1 Lindab InDoo Building Integrated Duct Systes

2 Introduction to Lindab InDoo We are facing one of the toughest challenges in decades. New buildings and existing hoes ust iniize their use of energy. In less than years all new build hoes are supposed to use alost no energy at all according to EU directives. This eans the buildings ust be better insulated and ore air tight. It also eans that existing hoes ust be upgraded, but when speaking about low energy houses it is eually iportant to think about ventilation and a good indoor cliate. The Lindab group was established in 99, and we are one of the world s leading ventilation suppliers. We can offer you a wide range of uality coponents and solutions for residential ventilation, all developed and tested by our inhouse R&D departents, and backed by our IT solutions and highly skilled staff - so if you choose Lindab as your partner you will be gaining access to Lindab s 0 years plus of experience and know-how. Lindab InDoo range is a syste of products, suitable for integration into doestic buildings. All circular plenu connections are supplied with gaskets as used on the renowned Lindab Safe syste, which fulfils the toughest deands for air tightness. This ensures that the ducting can be interconnected uickly and easily whilst leaving you safe in the knowledge that undesired leakage will be inialized. All anifolds and plenu boxes have a Sart Lock function which allows Lindab s LFPE seiflexible duct to be attached with a siple push and click and can be reoved uickly and siply without the need for tools and with no daage to either the flexible duct or the plenu/anifold. If noise sensitivity is an issue then low levels of noise are ensured with our optional specially developed silencers, these products, together with other ites fro Lindab s extensive range such as dapers, silencers, valves and grilles, provide you with a coplete high uality syste for residential ventilation. Lindab s Sart Lock Siply Push and Click to safely lock the flexible ducting in place safe in the knowledge that Lindab s gasket syste will iniise leakage without the need for tapes or sealant. To reove or reposition the flexible duct siply pull back on the Locking Tab and the duct can siply be detached without daage to either the duct or the spigot.
