Replacing double glazing

Replacing double glazing with even better insulating glass is the basis for saving on energy costs. Another reason to replace double glazing is because the window frames also need replacing. That way, you kill two birds with one stone. If only the glass is replaced, HR++ or triple glazing can be chosen. Of course, it is also possible to opt for standard double glazing again because of the costs.

Costs for replacing double glazing

It is of course important to know what the costs are for replacing double glazing. If you choose the cheapest option and go for standard double glazing again, the minimum cost is £45 per m² for a glass thickness of 4 millimetres. For a thickness of 8 millimetres, the cost of double-glazing replacement rises to around £65 per m². To give more insight into the cost of double glazing, a summary of average project prices including installation is shown below.

If you are about to replace double glazing, you have the option of choosing an even better insulating solution, for example HR++ insulating glass or triple glass. This glazing insulates even better and provides a comfortable warm base in your home. Moreover, you save even more on energy bills this way than if you replace double glazing with the same type of glazing. When replacing double glazing with HR++ or triple glazing, you live with extra comfort. The cold and draughts are eliminated and there is no condensation on the inside of the windows. Moreover, this glazing also provides extra sound insulation.

All the advantages of replacing double glazing with better insulating glass at a glance:

Step-by-step double-glazing replacement

The process of double-glazing replacement in a home or commercial building follows a number of steps. It is important that the glass is measured professionally. The correct measurements are important for replacing the double glazing. After measuring the glass and choosing the type of glazing, the glass is ordered. Once the glazing is in place, the first step is to apply cellular tape. Cellular tape is applied to the glazing beads and the rebate to ensure proper pressure distribution. The use of support blocks ensures good support for the glazing. After that, adjustment blocks can be applied if necessary.

Applying glazing beads when replacing double glazing

Once the double glazing has been replaced by new glazing, you are not there yet. Glass slats still need to be applied. When replacing double glazing with new glass, a venting glazing batten should be placed at the bottom. By the way, this can also be a nose strip that rests on rubber blocks for optimal ventilation. The use of a bit of sealant is useful in this case, so that the blocks stick to the rebate, as it were. The sides and top of the glazing receive ordinary glazing bars. Finally, a top seal takes place by sealing the inside and outside.

Extra options when replacing double glazing

When replacing double glazing, you again benefit from extra advantages. Moreover, there are options to opt for additional features. For example, by opting for solar control glazing with double glazing replacement. Or by purchasing soundproof double glazing or extra insulating glass. Solar control glass reduces heat transmission by up to 60%. Soundproof glazing reduces noise by up to 70% compared to standard double-glazing. You can also optionally choose fire-resistant glass or burglar-resistant glazing.

Budget for double-glazing replacement

It is advisable to take your budget into account when replacing double-glazing. The first thing to consider is the options available. Do you prefer standard double glazing again? Or do you want to save extra on energy bills and benefit from optimal comfort? The costs are a bit higher with HR++ glass and triple glazing, but then there are additional benefits you will enjoy. And what about the extra options, such as solar control or soundproof glass?

Compare costs when replacing double glazing

When replacing double glazing, it is important to compare the costs of different glaziers. One company will charge a higher price for replacing double glazing of, say, 15m² in an entire house than another company. So while in this example you already take a price of £2,000 euros into account, it is also possible that another company will present a quote for £2,500 euros. Avoid unnecessary high costs by getting several quotes from different glass specialists and choose the price/quality ratio that suits you.
