Can You Change Single Glazed Windows to Doubled Glazed?

Double-glazing is now more popular than ever and the vast majority of UK homes have double glazed windows. The concept of double glazing is not a new one. Double-glazed windows have been around since the 1970s, with aluminium frames having been replaced by UPVC windows. In this article, we will look at why you may wish to consider upgrading your single glazed windows if you haven’t yet done so.

Can Single Glazing Be Replaced with Double Glazing?

Replacing your existing windows with double-glazed windows offers several benefits that make it a worthwhile investment for homeowners. Here are some key advantages:

Improve the Energy Efficiency of Your Home

Energy efficiency is a hot topic right now, especially with the recent increases in fuel costs. High-performing double glazing is energy efficient and provides better insulation, reducing heat loss during winter and preventing heat gain in summer. This leads to lower energy bills and less reliance on expensive heating systems.

Improved Sound Insulation

Double-glazed windows have an additional layer of glass that acts as a barrier against outside noise. This can help create a quieter and more peaceful indoor environment. Double glazing will reduce outside noise if you live on a busy main road, but if noise is a big problem, consider triple glazing instead.

Increased Security

Single glazed windows are a security risk and installing double glazing enhances the security of your home. The multiple layers of glass make it harder for intruders to break in, providing an additional layer of protection for your property, and UPVC windows typically come with a five-point locking system that’s much more difficult to force open.

Reduced Condensation

Condensation occurs when warm air inside the house comes into contact with colder surfaces, such as windows, and is a big problem in many modern homes. Double glazing helps reduce condensation by maintaining a consistent temperature on the inner glass pane, which helps to prevent moisture buildup.

Enhanced Comfort

With improved insulation and reduced heat transfer, double-glazed windows make living spaces feel a lot more comfortable by maintaining a consistent indoor temperature throughout the year.

Upgrading to double-glazed windows means you can enjoy all of these benefits and create a more energy-efficient, secure, and comfortable home environment.

Aesthetic Appeal

Modern double-glazed windows are aesthetically appealing and come in a range of styles and colours, such as thin double glazing, timber effect frames, and more. Upgrading your windows will improve the appearance of your home and make it more attractive to potential buyers if you decide to move.

Not All Homes are Suitable

While changing from single glazed to double glazed windows offers many benefits, not all homes are suitable.

Listed Buildings

Properties with historic significance or located in heritage conservation areas such as Grade I and Grade II listed buildings have strict regulations regarding window replacements. Homeowners may be restricted from upgrading to double glazing to maintain the original character of the building. In the case of Grade II homes, this doesn’t mean you can’t upgrade your windows, but standard windows might not be suitable.

In this case, you will need to fit approved windows in a suitable style, such as a PVCu sash window that looks like an original Victorian sash window. Most window replacement companies have heritage windows as well as cheaper styles. If in doubt, speak to your local planning department to check what’s allowed.

Cost Considerations

Upgrading to double glazed windows can be a significant investment. Homeowners on a tight budget may not be in a position to upgrade their old windows, although there are usually credit deals and special promotions available from larger companies. It’s also worth noting that upgrading from single-glazed windows to double-glazed windows will save you money in the long run and add value to your property.

Tenancy or Lease Restrictions

If the property is rented or subject to lease agreements, the landlord may have restrictions in place on making alterations or upgrades to the windows. This would require approval from the landlord or the property management company. However, rental homes must meet minimum energy efficiency requirements by 2024, so landlords may need to replace old windows if they haven’t already done so.

Building Regulations

Replacement windows must adhere to Building Regulations, which cover:

  • Thermal efficiency
  • Fire safety
  • Safety Glazing
  • Ventilation
  • Accessibility

Any new windows installation should come with a FENSA certificate from the installer, which means it meets Building Regs. If your installer doesn’t provide one, you can pay for the local authority Building Inspector to check the installation and provide a retrospective approval certificate.

Choosing a Double-Glazing Installer

Be vigilant when looking for a double-glazing installer. There are a lot of companies out there, from well-known brands to small, local installers. Local fitters are usually cheaper, but make sure they come with good reviews and can provide a FENSA certificate, as this protects you from the pain of a sub-standard installation.

Glazing Repairs

An upgrade isn’t always necessary. Broken windows can usually be repaired, even double-glazed windows. We can fix all kinds of windows, even toughened glass and office windows. Repairs can be carried out as a matter of urgency, so your home or commercial building is watertight and secure as quickly as possible.

Before upgrading to double glazing, consider all of the above factors. If double glazing is not an option, switching from single glazing to secondary glazing might be worth considering.
