ECO WATT.
THE FIRST OPENABLE ENERGY CLASS
A++ WINDOW ON THE MARKET.
Lammin Eco Watt is the first openable energy class
A++ window on the market as classified by Motiva*.
The window is equipped with quadruple panes and
a unique protected outer sash structure (PRH FI
7415/2007).
The inner and outer sashes of the aluminium-protected
energy-efficient window are made of durable
Finnish pine, and their manufacturing process
consumes significantly less energy than aluminium
refining. Only the external parts exposed to rain and
sunlight are made of aluminium profile. The entire
protection on the wooden outer sash is made of
edge-polished glass, so the sash does not require
any care or maintenance aside from washing.
The Finnish Patent and Registration Office has
granted design protection for Eco Watt. Its low
energy consumption is unparalleled: only 36 kilowatts
per square metre a year when the U-value is 0.62.
The U-value, i.e, the thermal transmittance factor,
indicates to what extent the window transmits heat.
The smaller the U-value is, the better the thermal
insulation in the window is.
*In the energy classification of windows, windows
are divided into energy classes on a scale of
A++ – G. More information on the energy efficiency
of windows is provided at www.motiva.fi.

SIGNAL WINDOW®
Signal Window® is an international trademark developed and registered
by Lammin Ikkuna Oy. The Signal Window® does not weaken the U-value
of the window but enables the significant strengthening of mobile signals
depending on the conditions.
The Signal Window® does not differ from regular windows in terms of
appearance, properties or installation, and it provides a cost-effective way of
improving indoor mobile phone reception. The Signal Window® is does not
require maintenance or electricity in order to operate.
The Signal Window® is not directed only at low energy buildings. This product
is recommended for use in all kinds of locations to increase the strength of
mobile phone signals now and in case of future changes, due to which signal
levels may be lowered by external factors.
The Signal Window® technological feature is available for most products
by Lammin Ikkuna Oy. For the windows equipped with this feature, the
dimensions, models, shapes, and colours; energy-efficiency of the glass
portion; safety-related characteristics of the glass panes; and additional
features and accessories are always selected individually for each order
and product to meet the customer’s needs.
