Why upgrade Hertfordshire or London homes with double glazing?
Double glazed windows

Double Glazing

The Chase Windows team have been supplying and installing high quality and high-performance double glazing for almost two decades, satisfying homeowners in and around London, Hertfordshire and Essex. Nowadays, all new homes have double glazed windows fitted as standard; of course, since April 2002 it’s been mandatory for homes with replacement glazing to comply with Building Regulations.

Ensuring comfortable thermal efficiency, security and ventilation are met, there are a number of benefits double-glazing offers that must be considered.

Save money on energy efficient double glazing Hertfordshire

Did you know up to 80% of energy loss escapes from around the edge of your window?

By replacing an entire single-glazed detached property with A++ rated double glazing, thanks to reductions in heating costs, you could make an average saving of £110-115 every year on your energy bills. Now, think about the average lifespan of uPVC, aluminium and timber windows and you begin to understand the potential energy savings connecting decades of enjoyment via high-quality double-glazed windows.

Double glazing reduces condensation issues

Did you know that 1 in 4 British homes have an issue with condensation or damp?

Condensation thrives on single glazed windows, becoming a daily occurrence to wipe them down throughout the winter months. By upgrading your windows to double glazing, less condensation will occur due to the simple fact that the interior pane of glass in a double-glazed window is warmer than the single pane in a single glazed window. Energy efficient double-glazing will also protect the structure of your building, as condensation, damp and mould can be incredibly destructive if left untreated.

Health-conscious glazing

Did you know that around 5.4 million people in the UK suffer from asthma?

By combining high-performance double glazing with innovative ‘warm edge’ spacer bar technology, the air quality within homes across Hertfordshire and London can actually be improved. Proactively preventing bacteria and viruses from thriving, coupled with condensation repelling and heat preserving qualities, double-glazing offers impressive health benefits too.

Acoustically sound double glazing London

The peace of mind double glazing offers continues through to its effective sound insulation aspects. Thanks to its second air filled barrier, outside sounds are subtly dampened to provide families across Hertfordshire and London with quieter, more peaceful living spaces.

Secure double-glazed casement windows

A more obvious benefit of double glazing, but none-the-less important, is the heightened security it offers. Providing a secondary defence, the glass is a lot harder to break whilst tighter window seals make them harder to force open. Combined with high-performance locking mechanisms, you’ve got a winning formula for burglar-proof windows!

Retain period features without compromise, via double glazed sliding sash windows

Original, single glazed sliding sash windows are inherently draughty and inefficient. So, it’s unsurprising that the popularity of double-glazed replacement sash windows is steadily on the increase. Effectively preventing heat and noise escaping, whilst retaining timeless period features, we have a range of double-glazed conservation-friendly uPVC and timber windows to choose from.

Double glazing can boost your EPC rating and property value

Did you know that by increasing an EPC rating by just one mark (e.g. G to F), this can potentially increase a property’s value by up to 6%?

Did you know that by raising an EPC to an A or B rating could increase a property’s value by an impressive 14%?

Energy Performance Certificates help homeowners and tenants to understand how much their energy costs are going to be, as well as determining ways to save on their energy bills in the future. By law, all homes must have an EPC in place to be legally marketed for sale or for rent, so that potential buyers or tenants have all the essential information at their disposal to make an informed decision. By upgrading single glazing to double glazing, on average this will boost EPC ratings by several noticeable points.

With double glazing and central heating key priorities for buyers, double glazing also has the potential to add up to 10% on to the resale value of East and South East properties.
