Products - Double Glazed
A basic double glazed unit consists of 2 no. panes of ordinary float glass assembled in a sealed unit. Up to quite recently that has been sufficient as it meant a marked improvement over single glazing. However in the modern world of energy conservation, It makes sense to choose units that will help maximise the energy available.
Trucurve ‘Green’ or ‘Green plus’ units do just that. The basic principle is that the heat inside is reflected back inside, while the Sun’s thermal energy is allowed through from the outside.
| Trucurve ‘Green’ units: | std float glass (outer leaf) |
| warm edge spacer bar with argon gas | |
| Low emissivity glass (inner leaf) | |
| Trucurve ‘Green Plus’ units: | Low-Iron float glass (outer leaf) has no green hue |
| Warm edge spacer bar with argon gas | |
| Low emissivity glass (inner leaf) |
All our units carry a 5 year warranty against defect once they are fitted in compliance with best industry practice guidelines and are sealed using compatible sealants.

Points to consider:
Airspace: This is the space between the two panes of glass in a sealed double glazed unit and is normally filled with de-humidified air or an inert gas like argon. The airspace acts as a buffer zone between the inside and outside temperatures.
Argon gas: When you fill the inside of a unit with argon gas you are increasing it’s insulating properties. Being an inert gas it is a poor conductor and as such does not allow the same level of heat loss as a unit filled with air.
Spacer bar:This is the bar that forms the space between the two glass panes.
In all our units we use a structural foam spacer bar to achieve this which has the advantage over the standard aluminium spacer bars of minimising the heat loss around the perimeter of the unit. The result is little or no condensation compared to other units. This type of spacer bar achieves what is know as ‘warm edge’ effect , that is, the temperature of the the glass at the edge of the unit would be only marginally cooler than the glass at the centre of the unit. In standard units the difference in temperature between the centre and the edge can be 50%.

Unfortunately soft coated glasses, which have a slightly better energy efficiency rating, cannot be curved as the coating is destroyed during the heating process.
Hard coated glasses on the other hand can be curved and are widely used to obtain low U value ratings. Low emissivity, or ‘Low E’ as it is widely know, is the most common type of hard coated glass used and when used with argon gas can achieve a typical U value in the order of 1.5 Wm2C.
Safety in double-glazed units : Where safety and security issues arise, these are covered by the use of laminated or toughened glass, or a combination of both. It is a matter of upgrading whatever glass is chosen by bonding it to another pane of glass or having it toughened.
Benefits of using Trucurve ‘Green’ and ‘Green Plus’ curved units.
- Reduction in the overall U-value of the window by up to 15% or 0.3 W/m2K
- 65% reduction in the thermal bridge effect around the edge of the unit
- Helps to comply more easily with the new building regulations
- More energy efficient thus reducing heating costs
- Improved comfort and maintenance because of reduced condensation
- Reduced gas emissions associated with the 'Greenhouse' effect, due to potential energy savings
