60%
less heat lost through iplus |
|
|
Heat loss is measured by U-value. Its units are watts/m2K. The
lower the U-value, the lower the heat loss.
iplus has a 60% lower U-value than conventional double glazing. |

|
How
heat is lost through glass |
|
|
| Heat is lost
through glass by a mixture of radiation, convection and conduction. iplus reduces the loss
by radiation to next to nothing. Filling the double glazed unit with a special gas such as
Argon, rather than with air, cuts down the convection and conduction losses too. |
|
|
|
|
iplus
is an energy saving glass |
|
|
| iplus
has a thin invisible coating on the inside surface of the double glazed sealed unit. An energy saving ability is provided.
Energy saving glasses
are also known as Low
Emissivity or Low E glasses.
Sealed units made with this kind of glass are
installed just like conventional units. |
|
|
|
How
energy saving glasses work |
|
|
| Conventional double glazed
units absorb heat from the inside of a room and radiate it to the cooler outside. With
iplus, long wave heat radiation from the room is reflected inwards and
little goes out. It works like reflective foil behind a radiator.
But short wave radiation from the sun is allowed in, so providing a free source of energy.

There is
greater noise reduction than
with toughened glass.

|
For
safety and security laminated glass
has benefits over toughened glass |
|
|
|
iplus comes in laminated form when there
is a requirement for a safety glass. |
|
-This provides security against intrusion from outside as well as
safety for people inside if the glass is broken.
-Laminated glass safeguards fabrics and furnishings by providing a high level of
protection against harmful ultra-violet light.
-It gives more clarity of vision by appearing just like ordinary glass without the
distortion that may be caused by 'waves' and 'ripples' in toughened glass. |
|
|
|
|
|
iplus
is neutral
- just like ordinary glass |
|
|
iplus has no colour when you look at it or through it. Other energy saving glosses
are slightly coloured or can look hazy under certain lighting conditions. But
iplus is
barely able to be distinguished from ordinary glass because of the special nature of its
coating |

Benefits to homeowners |
|
|
|
|
1) Less
heat loss so lower fuel bills
The iplus coating saves energy by reflecting back heat from fires and radiators.
But at the same time it allows the free heat from the sun into the home.
Thermostats may be set 1 or 2 degrees lower with no loss of comfort. This saves even more
money.
In a new home or if you are installing central heating, you may be able to save money by
puffing in smaller radiators and boilers.2) Reduces unpleasant internal condensation
Condensation is caused by damp warm air
meeting a cold surface. With iplus the warmer inside
surface reduces the risk of condensation.
|
3) More usable space
With iplus the inside surface of a window is warmer so cold
down-draughts are reduced. When it's freezing outside, the inside glass temperature will
be 5°C or 6°C wormer than with conventional double glazing.
This means that cold zones near a window are eliminated so more space in a room can be
used.
4)
Helps save the environment - the green choice
In the UK one half of all energy is used to heat buildings. Burning less fuel means less
harmful carbon dioxide is released into the atmosphere. So increasing your own comfort and
saving yourself money by choosing iplus helps save the environment too! |
