A product that has been found in our homes for decades, double glazing is found in windows and doors. Whilst we may all be familiar with these products, few of us are aware of the specific facts and regulations which govern them – so what are they?
Anyone who has considered investing in double glazing is guaranteed to have heard about the financial savings and increased energy efficiency they offer. They reduce carbon emissions, improve heat retention and provide UV protection – making them the perfect home improvement.
Yet, many consumers remain in the dark over exactly what these improvements amount to. To shed some light on the situation, here are all the facts and regulations you need to know about double glazing:
The facts: Origins and history
rigin: pre 20th century double glazing is believed to have originated in Scotland.
Modern day: an estimated 70% of homes are claimed to have double glazing fitted with cheaper installation costs and widespread appeal prompting the popularity.
The facts: Savings and benefits
Carbon emissions: carbon dioxide emissions are reduced by approximately 740kg a year through the use of double glazing. Back in 2008, this saved more CO2 than switching to the best electricity tariff by more than seven times. If everyone used double glazing then almost five million tonnes of CO2 would be saved.
Heat retention: whilst windows are responsible for one fifth of the heat lost from our homes, double glazings cuts this in half.
Noise reduction: with an additional pane of glass used in their construction, double glazed windows help to keep external noise disruption to a minimum, lowering it by approximately 40db.
UV protection:extra glass means additional protection from UV rays. If a tint is added to the outside pane then UV light is reduced by more than 85%.
Home security:almost all burglars gain access to homes through a door or window. Double glazing makes this harder and a study in Nottinghamshire found estates with double glazings saw a 41% reduction in the number of burglaries committed.
Financial considerations: all of the above benefits lead to impressive financial savings. Increased heat retention saves approximately £80 a year, whilst the most energy efficient windows can generate an annual saving of as much as £165. Double glazings should last for at least 20 years, meaning these savings soon outweigh the initial installation costs.
The regulations: Installation and replacement
Fitting and replacements: in April 2002, new regulations were introduced for double glazing under the Building Regulations. All double glazed windows must comply with the thermal and safety standards outlined in this.
Companies: as part of these regulations, businesses which are pre-registered with the Fenestration Self-Assessment(FENSA) scheme can self-certify their work to show it abides by the Building Regulations. FENSA regularly assesses their companies, which exceed 7 million, and offer a five to ten year insurance guarantee for homeowners on all installations.
Well worth a read. Got great insights and information from your blog. Anyone who has considered investing in double glazing is guaranteed to have heard about the financial savings and increased energy efficiency they offer. They reduce carbon emissions, improve heat retention and provide UV protection – making them the perfect home improvement. I really enjoyed reading the post. Thanks Again.
Grateful for the valuable insights shared here! Double glazing is an effective solution for improving energy efficiency and reducing noise pollution. It works by trapping a layer of air or gas between two panes of glass, offering better insulation than single glazing. In the UK, regulations require that double-glazed windows meet certain standards for thermal performance and safety. This includes compliance with building codes and energy efficiency guidelines, which help reduce carbon footprints and lower energy bills. Homeowners must ensure that any double glazing installation is done by certified professionals to guarantee compliance with these regulations. Grateful for the valuable insights shared here!.
