Super Low U-Value Units

'Optitherm Advantage' 0.9 W/m2k Double Glazed Units

Treforest glass offer an 'Optitherm Advantage' unit which achieves performance comparable to triple glazing within a double glazed unit. The unit combines two low-e coatings to reach a remarkable u-value of just 0.9 W/m2k, offering the thermal performance benefits and cost savings previously only associated with more expensive triple glazing.

Triple Glazed Units

Treforest Glass offer a triple glazed unit in a 28mm overall to achieve an impressive 0.6 W/m2K centre pane u-value or an incredible 0.4 W/m2K centre pane in a 36mm unit.

0.4 W/m2K U-Value Triple Glazed Unit Construction 36mm

2 panes of high end softcoat, 2 x krypton gas cavities

0.6 W/m2K U-Value Triple Glazed Unit Construction 28mm

1 pane of high end softcoat, 1 pane of standard softcoat, 2 x krypton gas cavities 

Before we take a look at the obvious benefits of triple glazing, first you have to understand how the glass in windows links in with the energy efficiency of the property. Firstly, there is direct heat loss, normally measured in u-values, and is basically the loss of heat over a particular area measured in time. The slower the heat escapes, the better. In recent years glass manufactures have achieved better results with Low-E (low emissivity) glass such as Pilkington KS or KS 1, Saint Gobain’s Planitherm Total + or Planitherm One II, which is a soft coating to stop energy escaping.

By adding another pane of Low-E glass it helps the u-value of the triple glazed unit, adding another barrier to stop heat escaping out of a room. We use warm-edge spacer bar, which acts as a thermal break inside the unit, stopping the transfer of cold air into the room, and warm air out of the room, thus reducing the risk of condensation. Most of the heat loss from a window travels through the edge of the glass. The warm-edge spacer helps, as its name suggests, keep the edge of the unit warmer. We fill the cavities of these triple glazed units with inert gases, such as Krypton or Argon, which helps create insulating pockets, thus improving levels of insulation.

One of the biggest trends in the double glazing industry has been the growth in demand for energy-efficient glass. Over the past 10 years the percentage of new homes featuring energy-efficient glass has gone from less than 10 percent to more than 90 percent. Today, innovators looking for further improvements are finding it in triple-glazing.
 
              Ensuring homes are warmer in winter and cooler in summer.
              Making savings on energy bills.
              Reducing carbon emissions.
              Reducing condensation.

Treforest Glass are a forward thinking, innovative Company and we feel that just like the consumer demand and legislation for Low-E glass over the past 10 years, the next 10 years will likely see a similar movement towards triple-glazing.

Triple Glazing may in some instances be the only way to achieve an ‘A’ rating in certain window frames.

Our triple glazing marketing campaign comes ahead of further revisions to the Approved Document L (ADL), expected in both 2013 and 2016, which will see the introduction of a 'zero carbon' policy for new homes. This means a building's CO2 emissions will need to be reduced to zero or offset in some way, providing a challenge for house builders. From 2019 the ADL regulations will apply to all commercial new builds and at some point it is widely believed that existing buildings will need to be refurbished to improve their energy efficiency too: triple glazing will be one of the measures most likely to be adopted.


Quadruple Glazed Units

Treforest Glass offer a quadruple glazed unit in a 36mm overall to achieve an unmatched 0.4 W/m2K
