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.

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.

TwinGlaze® includes 6.38mm Laminated Security Glass

+
TwinGlaze® Double Glazing includes an exterior pane of Laminated Security Glass which is comprised of 2 sheets of 3mm glass fused together by a 0.38mm Polymer Interlayer.
Similar to glass used in car windshields, laminated glass stays intact if stuck by a hard impact to provide enhanced security against attempted break-ins, accidental injury and severe weather conditions.
The Polymer Interlayer further enhances the acoustic performance of your double glazing while delivering the added benefit of 99% UV reduction to guard against fading of your furnishings and interior surfaces.

TwinGlaze® includes 4mm Toughened Safety Glass

+
Toughened glass, also known as tempered glass, is four to five times stronger than standard glass and will crumble uniformly into small fragments or pebbles, rather than splintering into dangerous shards if struck by an extremely hard impact.
The 4mm pane of Toughened glass has further enhanced thermal properties through the inclusion of a special Low 'E' Nano-Metallic Coating.

TwinGlaze® includes Argon Gas

+
TwinGlaze® Double Glazing incorporates an optimum 12mm Thermal Argon Gas gap between the two panes of glass to achieve maximum energy efficiency and thermal performance.
Dense, crystal clear, non-toxic argon gas is infused in between the two panes of glass in the insulated glass unit (IGU) to significantly enhance double glazing performance by an extra 10% when used in the place of common dehydrated air.
The Argon Air Cushion is hermetically sealed between the two glazing panes to enhance the lifelong thermal performance of your double glazing.

TwinGlaze® includes Low 'E' Solar Glass

+
TwinGlaze® includes an interior pane of 4mm Toughened Safety Glass with Low 'E' to further enhance the year round energy efficiency and performance of your double glazing.
Low 'E' is a transparent nano-metallic coating that is infused onto the interior pane of toughened safety glass to further enhance the performance of your double glazing in Summer & Winter.
Low 'E' reflects harsh direct sunlight and UV away from your home in Summer while reflecting your indoor generated heat back into your home in Winter to deliver life long savings on heating & cooling bills.

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 1.40 to deliver superior protection against heat loss in Winter & heat gain in Summer.

Direct Sunlight Protection & SHGC (Solar Heat Gain Coefficient)

Radiant Heat is the heat generated by direct sunlight through a window system. TwinGlaze® Double Glazing has a SHGC of 0.53.
TwinGlaze® double glazing effectively addresses radiant heat transfer into your home by reflecting 47% 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.
