Types of double glazing

When replacing glass, new double glazing is usually chosen. This type of glass is strong and insulates well. In addition, HR++ glass – where the cavity between the two panes of glass is filled with argon gas instead of dry air – is the most commonly used glass. These are all the different types of double glazing with the corresponding specifications.

Tips for glass replacement

If your glass is being replaced, it is important that this is done properly to prevent any leaks or draughts. The following tips are useful when getting a window replaced:

1. Cheap does not mean cheap

The cheapest glass does not necessarily mean the most economical glass. In most cases, cheaper glass insulates less than the more expensive versions. So always look carefully at the expected savings of the new glass and base your choice on that.

2. Think carefully before choosing the best insulating glass

On the internet you will be inundated with tips to always choose the best insulating type of glass. However, this is not always more advantageous. For instance, HR++ is considerably more expensive to buy and the benefits of the extra insulation do not outweigh the cost in every situation. Often, HR++ glass is already sufficient. So weigh all the pros and cons carefully before making your choice.

3. Look for quality marks

Always pay attention to the quality of the glass and the specialist when you decide to replace a window. Nothing is more annoying than finding out afterwards that mistakes were made in replacing the glass. In addition, look carefully at the professional’s quality marks and certificates. When replacing glass, preferably choose a company that is a member of the trade association MaintenanceNLor has a GBO professional certificate. Companies affiliated to OnderhoudNL offer a 5-year guarantee on the installation of insulation glass. This guarantee can also be extended for another five years.

4. Ventilation grilles open

Isolation glass has the great advantage of bringing down energy bills, but good insulation also means less air ventilation. A poorly ventilated house can cause mould and damp. Therefore, if they are present, always leave the ventilation grills in the window frame open. Do your windows not yet have ventilation grills? For your comfort and health, it is advisable to have them installed immediately.

Advantages of glass replacement

Replacing glass offers a large number of advantages. Below are the advantages of replacing single glazing to double glazing or HR++ glass once again:

• You are less bothered by draughts.
• Insulated glass saves on energy costs.
• Double glazing is more soundproof than single glazing.
• Double glazing is safer, for example against burglaries or fire.
• The discolouration of furniture and attributes in the house is less because less UV rays are transmitted.
