WEBVTT 00:00:04.000 --> 00:00:07.000 [Music] 00:00:15.220 --> 00:00:19.000 This house is something truly special – 00:00:19.000 --> 00:00:22.000 because it has a very unique type of roof. 00:00:22.000 --> 00:00:24.000 There is no conventional roof truss. 00:00:24.000 --> 00:00:27.000 We work with a fully solid roof. 00:00:27.000 --> 00:00:31.000 Fully solid means: it doesn’t stop with the walls. 00:00:31.000 --> 00:00:38.000 The roof itself is also made of solid material. 00:00:38.000 --> 00:00:43.000 It only needs plastering from below – making the roof practically a fifth wall. 00:00:53.000 --> 00:00:56.000 Aerated concrete is an ecological building material. 00:00:56.000 --> 00:01:02.000 It is produced with little energy and simple natural resources. 00:01:02.000 --> 00:01:06.000 Another advantage: in the Leipzig region airports and railways play an important role. 00:01:07.000 --> 00:01:10.000 There, increased sound insulation is especially important. 00:01:14.000 --> 00:01:20.000 In summer, the roof surface can heat up to 80 or even 90 degrees. 00:01:20.000 --> 00:01:23.000 Nevertheless, it stays pleasantly cool underneath. 00:01:23.000 --> 00:01:27.000 That is thanks to the mass and weight of the roof panels. 00:01:27.000 --> 00:01:31.000 In winter, the roof keeps the warmth inside. 00:01:31.000 --> 00:01:36.000 It provides excellent insulation, enhanced by the additional roof insulation. 00:01:36.000 --> 00:01:42.000 That is a major advantage compared to a conventional wooden roof truss. 00:01:43.000 --> 00:01:47.000 And: the roof is very easy to install. 00:01:47.000 --> 00:01:52.000 The panels are up to six meters long. 00:01:52.000 --> 00:01:55.000 They are simply laid onto the roof. 00:01:55.000 --> 00:01:59.000 On the outside, we connect them to the walls using a ring beam. 00:02:00.000 --> 00:02:06.000 For 13 years, we have been building in Leipzig individual, solid single-family houses. 00:02:06.000 --> 00:02:10.000 We work together with local craftsmen. 00:02:11.000 --> 00:02:13.000 That ensures the highest quality. 00:02:14.480 --> 00:02:20.000 The Hebelhaus solid roof – a smart investment in the future.
