Insulating glass structure

Warmwave Double Glaze The pane facing the room consists of toughened safety glass ( TSG )and is provided with a special coating without heating wires on the side facing the gap between the panes. The outer pane is made of float glass, toughened safety glass or laminated safety glass and is usually provided with a heat insulation coating. The spacer is supplied as so-called “warm-edge system” made of plastic available in common sizes from 8 mm to 27 mm thickness:

Considerable reduction of heat loss in the border area of the insulating glass pane compared to “normal” insulating glass, because no thermal bridges exist. The gas filled into the gap between the panes is argon or krypton as desired by the customer. The Ug value in accordance with DIN EN673 is 1.2 W/m2K. The cables are lead through at the edge. The insulating glass is electrically protected ( Protection class 2 )

Tempered Glass

  • Temperature difference strength = max. 150K between centre and edge of the pane.
  • Bending strength = 120N/mm2
  • Resistance to pressure = 700N/mm2
  • Scratch hardness in accordance with MOHS = 5 – 6
  • Max. current load of the special coating = up to 1W/cm2, of the glass surface = 10kW/m2

Warmwave Double GlazeElectrical power
The electrical power of WARMWAVE DOUBLE GLAZE® insulating glass can be designed as desired ( min. 20 W/m2 / max. 800 W/m2 ). Suitable for permanent temperatures of up to around 70 °C. Higher power can be installed for special applications in which the heating-up time needs to be extremely short.

Combinations
WARMWAVE DOUBLE GLAZE® can be combined with the following types of glass: Float glass / TSG or LSG / Solar glass

Additionally, WARMWAVE DOUBLE GLAZE® is available with a sun-blind or reflecting foil integrated in the gap between the panes.

Frame types
WARMWAVE DOUBLE GLAZE® can be installed into the following types of frames :Wood, Plastic, Aluminium, structural glazing

Electrical connection and regulation In addition to series and parallel connection, the electrical power of WARMWAVE DOUBLE GLAZE® is adjusted to the requirements of the building and the user in residential buildings, up to a maximum specific power of 800W/m2. Since power requirements vary ( day / night, wind, insolation, etc.), a power regulation system is usually used.

The following options are available:

  • Power regulation based on air temperature measurement
  • Power regulation based on glass surface temperature change
  • Combination of both

We calculate current and voltage for each pane with a view to the specific power required and the control of each pane and the total heated glass surface.

Power consumption
The power required to operate WARMWAVE DOUBLE GLAZE® depends on the application and is strongly dependent on the size of the windows in relation to the floor space. For special applications, the power requirements can be determined by means of calculations or tests.

Efficiency
The efficiency of WARMWAVE DOUBLE GLAZE® is around 90 %, i.e. around 90 % of the electric energy put in is used to heat the room.

Appearance
WARMWAVE DOUBLE GLAZE® is absolutely invisible in the window pane. If the window surface is sufficiently large, there’s no need for additional heating and disturbing radiators.

Cosiness
The warm surfaces of WARMWAVE DOUBLE GLAZE® create comfortable inside temperatures. The heat is radiated into the room and provides a pleasant climate. The advantage of radiant heat is that the air inside the room needs not be heated first to obtain the desired effect. As a consequence, it’s getting warm shortly after the heating is turned on.

Cost effectiveness
WARMWAVE DOUBLE GLAZE® contributes to saving energy, because the perceived cosiness depends on the operative temperature, the mean value of the air temperature and the average surface temperature of the surfaces enclosing the room. An increase of the mean surface temperature of the window surfaces in the room allows the room temperature to be reduced by 2 °C on average. This means a reduction in power consumption by around 12 % and, because the air temperature is lower, less heat is lost when the air in the room is renewed. The room air quality is perceived as being more pleasant. WARMWAVE DOUBLE GLAZE® is a low-temperature heating system. Large glass surfaces in the room are used for heating and thus the temperature of the heating medium is just slightly higher than the room air temperature.

Safety
The heated room-side pane of the WARMWAVE DOUBLE GLAZE® insulating glass is made of high-quality toughened safety glass ( TSG ), while normal insulating glass panes in windows usually consist of float glass.

Health
Headaches and hardened muscles in the back and neck as a consequence of cold convection near windows are avoided. Still and thus dust-free air is a prerequisite to an ideal room climate that preserves your health.Therefore, WARMWAVE DOUBLE GLAZE® is the optimal heating system also for allergic persons and asthmatics. In conventional heating systems, large surfaced radiators generate hot air which rises up, while cold air is flowing up from the ground. This convection creates an unhealthy draught which constantly whirls up dust and allergens. Moreover, convection heating withdraws oxygen and humidity from the air, and dry, low oxygen air full of dust and germs means higher susceptibility to respiratory diseases.

Ideal for

  • Old and new buildings
  • Office buildings
  • Public houses and hotels
  • Swimming-pools and indoor pools
  • Hospitals and old people’s homes
  • Glass extensions and conservatories
  • Roof extensions
  • Buildings in which conventional heating systems cannot be installed
  • Canteen kitchens
  • Inspection glasses on machines and installations
  • In special designs as laminated glass in overhead areas, for vehicle and ship glazing, glazing of freezing chambers and refrigerating sets and other applications aiming at reducing condensation/icing

Cost saving

  • No chimney-sweep
  • No maintenance
  • No emissions
  • No wear
  • Single-room control, thus no regulation loss as, for instance, in the case of a central control system of a heating boiler

Easy installation

  • Only the connection line coming out of the edge of the insulating glass pane needs to be lead through to the outside via the window frame and connected to a power source. Apart from that, the windows are installed in the same way as conventional insulating glass panes.
  • Can be retrofitted at any time.
  • No external connection costs

Advantages of WARMWAVE DOUBLE GLAZE®

  • The heating is integrated into the glass and absolutely invisible. No space is consumed and no erection space is needed.

This gives you freedom to design your interior.

  • The whole surface of the pane facing the room is heated and thus an evenly distributed radiant heat is emitted into the room. The result is a pleasant room climate.
  • No more cold glass surfaces — just comfort and cosiness.
  • Favourable room air hygiene conditions due to low convection and reduced dust formation.
  • No cold flows of air or condensation on the panes, therefore also optimal for roof glazing.
  • Low-cost installation, easy to install compared to conventional heating systems. Therefore especially suitable for renovation and extensions.
  • The warm surfaces of WARMWAVE DOUBLE GLAZE® heated insulating glass considerably enhance room comfort!
