What are double glazed windows?

An insulated cup unit (IGU) combines many glass panes right into one window system. Most IGUs are double glazed (two panes of glass) with 3 panes (triple glazing) plus becoming more prevalent because of increased power bills. The panes of glass in IGUs are divided by a spacer along with a yet level of fuel or even air. The cup will be fitted into window frames, that is created broader to accommodate the 2 panes.

The advantages of double glazing Bournemouth

Double glazed windows are the most perfect power efficient option with the additional benefit of minimising noise. The closed air gap between the 2 panes acts as an additional level of insulation. This added thermal resistance cuts down on the level of heat escaping in cold weather and helps to keep the home of yours at an cozy temperature. Double glazing has got the reverse impact in summer time, preventing unwelcome heat from coming in to the house. This extra insulation lessens the reliance of yours on artificial heaters and ac units and can eventually reduce the electricity costs of yours.

When you’re near a window, your comfort is impacted by the heat on the cup. With double glazing it is tougher for any undesirable outside temperature to transport through, making the interior pane in close proximity to room temperature. Double glazing also lowers condensation that will lead to the unhealthy formation of mould.

Sealed double glazing works well at reducing medium to extremely high frequency noise like the human voice. A big difference in cup thickness between the outer and inner panes will enhance sound reduction further.

Double glazed windows are regarded as a more secure choice when compared to regular single pane windows. 2 sheets of glass are much harder to break than a single and for greater protection you are able to establish toughened or maybe laminated glass.
What to look for
Total amount of room between panes

The usual room between panes ranges from 6mm to 20mm. A minimum space of 12mm is suggested for optimal winter performance. Conversely, for excellent acoustic management and also in order to minimize very low frequency interference like aircraft and traffic, the top air gap highly recommended is 150mm or perhaps over. Note that such huge gaps allow convection to take place between the panes and lower insulating performance.


For much better power efficient performance choose double glazing with a space of ten to 20mm between the panes.

What is in between

Because the area between the panes in double glazed windows is completely sealed, it functions as an insulator, limiting the transfer of air that is cool coming into the house of yours. Acoustic and thermal performance could also be improved when gas fills this particular space. The most used gas used is argon with low conductivity properties to boost insulation.


Inert, low conductivity gas inserted between panes will boost overall performance.

Double glazed devices include a spacer that is a metal or maybe polymer strip which separates the 2 panes of glass. Typically, spacers contain a desiccant (drying agent) to get rid of water caught in mid-air space.
Kind of glass used

A number of various glass sorts, like laminated and low-e, may be utilized in double glazing devices to further improve energy efficiency and noise control. Low-e glass will even further decrease the level of heat escaping while fuller laminated panes disrupt sounds waves to develop acoustic performance.
Typical problems

Windows have to be considered as an entire unit. The framing material you opt to complement the glass of yours could improve its performance or in a number of instances lower the energy of its efficient properties. Standard aluminium window frames easily do heat and cool of course, if not thermally enhanced, may very well eliminate some advantage from setting up costly double glazing.

Just how well the cavity is sealed and also the kind of spacer being used is likewise vital element to think about. If the double glazed device isn’t sealed appropriately or even if the spacer doesn’t have adequate desiccant, it is able to decrease condensation and performance will show up on cold surfaces.
