Sealed Unit Repairs

The obvious reason for replacing the glass in your double glazing is due to the seal breaking which makes moisture between the 2 panes. It’s easy enough to replace a unit like for like, however have you ever considered it as a way of altering the appearance of your window?
For example, changing of clear glass to obscure, adding of Georgian bars or diamond/ square leads or even change the unit for a bevelled or stained glass effect, which has a fantastic effect on a front door or conservatory fanlight!

To help eliminate condensation you might consider changing the sealed units to upgrade the effectiveness of the window, or if your window sills and internal panes of glass are saturated with water, mould can also become a problem and subsequently health issues may follow.

If condensation is an issue changing your glass so it incororates the following 3 elements will help…

Argon gas

This gas is a colourless, odourless, non-flammable, non-reactive and inert. It is used to reduce heat loss in double glazing sealed units by slowing down convection inside the air space.

Filling the gap between the glass panes with this low-conductivity gas improves window performance by reducing conductive and convective heat transfers. The phenomenon results from the fact that the density of the gas is greater than the density of the air. Argon gas is extremely cost-efficient, has excellent thermal performance and works very well with Low E coated glass.

The above picture shows the difference between the centre pane being an “A Rated” unit, opposed to the glass either side being standard glass and covered in condensation.

Thermospacers

We believe this is the most important aspect of reducing condensation. Did you know that up to 80% of a window’s energy loss occurs at the edge of the glass due to the old aluminium spacers. A warm edge spacer can make the temperature at the edge of the glass up to 65% warmer! It is also 950 times less conductive than the aluminium spacers. These spacers are made from a particular type of foam and are more durable as it can expand and contract much better than rigid metal systems – a major cause of stress fractures in conventional sealed units. They are also proven to absorb sounds and reduce noise levels by up to 2DB.

So as you can see, a blown unit is not always the reason to change your glass. Remember, simply changing the unit is a cheaper alternative to replacing the whole window.

pilkington glass

Non K glass units absorb heat then radiate it again on the colder outside surface. Pilkington K Glass™ has a low emissivity coating which is positioned on surface 3 (counting from the outside) of the unit.

The Low E coating is a poor radiator of heat, so the heat absorbed by the coated glass does not travel across the air gap to the outer pane and the cold outside. Instead the coating reflects the heat back into the room. Windows incorporating Pilkington K Glass allow heat from the sun through and keep heat inside, thus making it easier and more cost effective to keep buildings warm.
