underfloor heating/cooling efficient energy distribution efficient energy distribution in the building as a specialist in the field of energy efficient building construction rehau supplies underfloor heating and cooling systems to meet almost any need these include sophisticated solutions for new buildings and renovation projects for floors walls and ceilings for either wet or dry construction methods the key component of all these systems is the rautherm s pipe made of high-quality high pressure cross-linked pe-xa in sizes 10.1 to 32 millimetres now supplies a pipe that is ideally tailored to the requirements of modern homes this pipe recommends itself by virtue of reduced construction depth and by virtue of markedly increased flexibility when compared to 16/17 mm pipes depending on situation and local circumstances underfloor heating and cooling systems can be installed using a choice of various studded panel or tacker panel systems pipe grids or track systems wet or dry systems the range is rounded off with sophisticated control technology systems for the broadest spectrum of system concepts as well as with an extensive range of accessories heating/cooling ceilings can also be used in either new buildings or renovation projects industrial underfloor heating systems are the ideal energy efficient option for heating warehouses and production rooms the high demands made on the material in terms of tons of weight are met by strong rautherm s pipes rehau provides sports facility heating systems for use in flexible sports floors separating the sprung floor from the underfloor heating system makes it possible to renovate the floor struc tailor-made underfloor heating/cooling systems for new buildings and renovation projects ture without disassembling the heating system outdoor facility heating systems make it possible to keep approaches and facilities free of ice and snow for safety s sake these could include helicopter landing pads hospital access roads and pedestrian zones pitch heating systems are special types of outdoor facility heating systems for sports stadiums and training grounds these systems are already proving their worth beneath more than 160 playing fields tailor-made system solutions and services rehau stands by its customers with a broad range of services for all residential and non-residential building projects as a globally active systems supplier we are experts in providing advice planning services and solutions with our own staff available all round the world we can offer our custmers help on a local basis such as in the form of globally active building project networks for major international projects that attract attention solutions for housebuilding for housebuilding rehau can offer custom solutions for efficiently heating and cooling using floors walls and ceilings measures to prevent heat transmission in combination with airtight building shells have markedly reduced the heating requirement of modern homes this trend makes it possible for underfloor systems to use pipes of smaller inner and outer diameters than up to now apart from the tried and tested rautherm s 17 x 2.0 mm with the rautherm s 14 x 1.5 mm rehau solutions for large buildings rehau also provides impressive heating and cooling systems for use in large buildings for maintaining comfortable temperatures in office and administration blocks concrete core temperature regulation suggests itself thermally activating the building s massive structural elements as an alternative to conventional air-conditioning systems radiant the new acoustic heating/cooling ceiling from rehau efficient room temperature control now sounds even better modern offices and homes feature open rooms with large windows and smooth walls in such interiors sound can spread with ease driving the noise levels up a host of heat sources causes temperatures to rise and adversely affects the indoor climate today air conditioning systems often guarantee comfort in terms of temperature humidity and air quality but cause draught and irritating background noise doing nothing to improve room acoustics rehau has tackled this problem and produced a system for heating/cooling as well as for absorbing sound the new rehau acoustic heating/cooling ceiling system for dry construction increases comfort levels and productivity in two ways at once this new system works like any other underfloor heating/cooling system i.e by radiation this saves a lot of energy and makes the system particularly economical motionless heating and cooling using water instead of the air creates neither draught nor background noise nor does it raise dust the improvement of room acoustics is achieved by the absorption of sound a special ceiling element was developed for this it consists of two perforated gypsum plasterboards bonded together and with fleece on the back making it possible to reduce noise on a permanent basis tried and tested rautherm s 10.1 x 1.1 mm pipes are used in these ceiling elements this guarantees our customers a standard proven system extending all the way from the manifold to the ceiling element efficient use of the ceiling for heating and cooling provides the architect with complete freedom when designing interiors three standard sizes make it possible to flexibly adapt to different room shapes three different perforation patterns make a wide range of architectural concepts possible the prefabricated elements are delivered direct to the building site and can be installed using standard dry construction methods acoustic heating/cooling ceiling systems will most likely be available from july 2011 they are intended for use in new buildings and in office and administration block renovation projects our local product specialists would be delighted to provide advice about room acoustics and heating and cooling systems at any time our rehau design centre is only willing to help you 5
