The Ongoing Fight
Against Condensation
»»Water condensation
on windows is a problem
that inevitably affects many
modern houses and apartments.
Condensing water not only
looks unappealing, but also can
affect visibility. The choice of
ClimaGuard® Dry by Guardian’s
Glass Group in Europe is a way
to get rid of “steamy windows”
while maintaining excellent
insulating properties.
Until recently, it was
commonly believed that the
phenomenon of condensation
was typical for windows with
high thermal performance
glazing. Moreover, external
condensation was widely
considered the signature of a
well-insulated, energy-efficient
window. How did this belief
come to be?
Good thermal insulation
glass does not allow the heat to
“escape” from inside the house,
so the outer pane usually stays
cold and allows the deposition
of water droplets from humid air.
This, however, is not the case with
the anti-condensation Guardian
ClimaGuard Dry glass.
The product’s advantage
lies in its innovative coating
that allows it to effectively

fight the phenomenon of
“steamy windows”. Field tests
conducted by Guardian in real
weather conditions show that
the average duration of water
condensation on ClimaGuard
Dry glass is just one hour. By
comparison, for self-cleaning
glass it is 7 hours, and for
regular float glass it can be up
to 8 hours. The all-new coating
provides excellent transparency
without compromising
insulation or energy-efficiency
of modern windows. The
coating is extremely durable and
requires no special maintenance.
Guardian ClimaGuard Dry
can be successfully used
both in new buildings and in
those undergoing a retrofit.
This innovative glass not
only effectively eliminates
condensation, but it also
improves the energy efficiency
of buildings and helps to
meet the highest standards
of sustainable construction.
ClimaGuard Dry glass can be
used in double- and triple-glazed
windows. The product must
be tempered to activate the
coating.

»»The product is
designed for sealing the
perimeter joint between
windows, doors and walls,
enabling the windows and doors
to be quickly and easily sealed
from inside the building. It seals
gaps from 2mm to 8mm, and
comes in two widths to give extra
thermal insulation equivalent to
A Rated (40mm tape) or A+ and
A++ windows (65mm tape).
The tape is weather tight
to 600 Pa (Violent Storm
Force 11) and has excellent
acoustic insulation properties.
Installing a window or door
using WIN2WALL will give
the window an equivalent or
better thermal property than
the window unit itself. Even the
smaller 40mm size tape, will give
the joint between the window
and wall a U-value of 1.2 W/
m2K, equivalent to an energy
A-rated window.
The larger size tape will give an
A-Value of 0.7 W/m2K, which
is even better than a triple glazed
Passivhaus standard window. The
tape is applied to the window
before installation and has slow
expansion speed to give ease of
installation for large windows or
even patio doors.
WIN2WALL also complies
with the Zero Carbon Hub

project by using materials
that fill the gap between
‘designed performance’ and
‘built performance,’ making it
particularly useful to new build
developers.
The tape is permeable
to outward moving vapour
diffusion according to the RAL
principles of 3-level sealing and is
more air tight on the inside than
the out. This guarantees that the
joint will dry out completely.
