Double glazing functions by incorporating two glass panes separated by a spacer bar, forming an insulating air gap. This gap impedes heat transfer by conduction and minimises air convection, effectively reducing heat loss.

Double glazing allows solar gain by trapping the thermal energy from sunlight using short-wave infrared radiation. To regulate room temperature and prevent overheating, low-emissivity (Low-E) glass with a special coating is recommended. This coating reflects shortwave radiation while maintaining daylight clarity and reducing the greenhouse effect. For added benefits, solar control glass coatings can filter light to reduce solar glare and protect furnishings.

Double glazing offers a multitude of benefits, such as noise reduction, enhanced insulation for a warmer home, decreased condensation, lower energy consumption and bills, and increased property value. Our windows cater to your specific needs.

Common Questions About Double Glazing

Get answers to commonly asked questions about TLC Windows and our services to make informed decisions for your home improvement.

What is the principle behind double glazing?

Double glazing uses two glass layers separated by an inert gas, reducing heat transfer due to the gas’s poor thermal conductivity.

How can I determine the quality of double glazing?

Quality double glazing includes two glass layers with a non-conductive gas between them, sealed hermetically, and features a low U-rating (around 1.3-1.5 W/m2K).

Is it worthwhile to upgrade double glazing installed 20 years ago?

Yes, it’s beneficial. Older double glazing may not offer the same energy efficiency and soundproofing as newer options due to its average lifespan of 15-20 years.

When is the ideal time to invest in double glazing?

Autumn is optimal for double glazing installation, offering more availability and better deals, ultimately reducing your heating costs when you need it most.

What's the ideal glass thickness for double glazing?

Double glazing typically consists of two glass layers with an overall thickness of 28mm, although 24mm is the optimal choice thermally, whether filled with air or argon cavities.
