TWINGLAZE COMPARED TO OTHER DOUBLE GLAZING

How does TwinGlaze® Differ to Full Frame Replacement?

+
Until now, the only way you could enjoy all the benefits of double glazing was to go down the costly and invasive path of a full frame window replacement involving stripping your home of all windows including curtains and all woodwork.
Removing and throwing out perfectly fine windows did not make environmental or financial sense.
Research and Development commenced in 2015 to develop a system to allow any single glazed window to be transformed into a fully insulated double glazed window for homeowners to enjoy all the savings and benefits of Genuine Double Glazing without the hassle, mess or expense of a full frame window replacement.
TwinGlaze® maintains the look and feel of your home by replacing the glass in your existing window frames with Genuine High Performance Double Glazing.

How does TwinGlaze® compare to uPVC (Plastic) Window Replacement?

+

UNDERSTANDING DOUBLE GLAZING SPECIFICATIONS

U-Values and Temperature Control Explained

+
U-Values measure the rate of transfer of heat (energy loss) through all glass and double glazing to help homeowners select the best performing glazing for their homes.
Double Glazing with the lowest U-Value achieves the greatest energy efficiency and reduction in heat loss from your home.
Single Pane Glass has a U-Value of 5.2 which translates to virtually no protection against heat loss while standard double glazing can range from U-Value 2.5 to 3.0 depending on the glass combination used by other manufacturers in their double glazing units.
TwinGlaze® Double Glazing boasts an impressive U-Value of 1.63 to deliver superior protection against heat loss in Winter & heat gain in Summer.

Direct Sunlight Protection & SHGC (Solar Heat Gain Coefficient)

+
RADIANT HEAT (direct sunlight)
Solar Heat Transfer in a Double Glazing Unit is measured by the units Solar Heat Gain Coefficient (SHGC).
Radiant Heat is the heat generated by direct sunlight through a window system. TwinGlaze® Double Glazing has a SHGC of 0.60.
TwinGlaze® double glazing effectively addresses radiant heat transfer into your home by reflecting 40% of solar radiation away from your home to reduce glare and Solar Heat Gain. TwinGlaze® further boosts the thermal performance of your double glazing in colder days by reflecting the Infrared Heat you generate through your heating system back into your home in Winter.
What Is Visible Light Transmission ?
VLT is a measure of Visible Light that is transmitted through a material. TwinGlaze® has a VLT of 80 while standard single glazing has a VLT of 90.
This means that TwinGlaze® will allow 80% of Visible Light to enter the Home while standard single glazing allows up to 90%.

How TwinGlaze® protects against UV Radiation & Direct Sunlight

+
TwinGlaze utilises Low E Coating which achieves a reduction in UV Radiation from entering the home as it reflects the radiant solar heat that is emitted by the sun.
Protecting your home from UV Radiation also prevents fading of floors and interior furnishings.
Will the TwinGlaze be more reflective than standard Glazing?
All Double Glazing creates a very slight mirroring effect due to the proximity of the two glass sheets compare to single glazing.
