Glass
Conservatories with glass in the roof certainly look classier
as well as having many advantages over polycarbonate. Being
a lot quieter when it rains, letting more light into the adjoining
room that the conservatory is attached too and if the right
type of glass is specified, giving better insulation in winter
whilst helping to keep the conservatory cooler in summer.
However, you must be careful about the type of double glazed
unit that is specified for your conservatory, although our
‘ULTIMATE’ glass is the best of the high tech
glasses that can be fitted, giving 75% heat reduction and
providing insulation that is nearly equivalent to an insulated
cavity wall, many do not come near to this specification.
See the table below for the most commonly used glass units.

SOLAR HEAT REFLECTION
This is the percentage of total solar energy (or heat from
the sun) not able to pass through the glass. The higher the
solar heat reflection the cooler the conservatory will be
inside.
U-VALUE
This is used to measure internal heat loss during colder
periods. The lower the number the greater the insulation.
 |
SELF CLEANING
The unique ‘Activ’ coating reacts with
UV rays in sunlight to generate a photocatalytic process
that loosens & breaks down organic dirt particles
on the surface of the glass.
The surface of the coating is hydrophilic. Therefore
instead of forming droplets it attracts water so that
it spreads & forms a thin film that ‘sheets’
away quickly & dries off without leaving unsightly
“drying spots”.
|
EASY CLEAN
Easy clean glass surface treatment is a mixture of Alkyl
Polysiloxanes suspended in Alcohol with a catalyst.
When applied to a glass surface a chemical reaction takes
place bonding the Alkyl polysiloxanes to the surface creating
water which will then run off the surface, carrying away any
deposits or pollutants suspended within it.
