Types of insulated glass

Currently, there are different types of insulation glass on the market. But what kind of insulation glass suits your situation? 

The standard insulation glass with a layer of pure air between the layers of glass is barely sold these days. Nowadays, so-called HR glass (glass which has a high yield) is a common type of insulated glass. This type of insulated glass insulates by implementing liquid in the space between the two layers of glass. 

The most frequently applied type of insulated glass by professionals is HR++. However, you can opt for other types of insulated glass. the difference between the types focuses on the insulating ability of the glass and the amount of heat that the glass transmits. This amount is indicated by a U-value. A low U-value indicates that the glass is better able to contain the generated heat, which will eventually reduce your utility costs. 

Below you can find a table with the average costs of insulated glass based on an average household with average energy usage. The savings on the right are based on an initial situation with single glazed windows.

Type U-value Avg. price per m2 Yearly utility savings based on 20m2 glass
Standard insulation glass 2,8 €60 €260
HR glass 2 €65 €300
HR+ glass 1,6 €70 €360
HR++ glass 1,1 €75 €400
HR+++ glass 0,5 €110 €430

Are my current window-frames suited for insulation glass?

It is important to examine whether your current window-frames are suited for the glass that you consider purchasing. In some cases, the new glass plates turn out to be too thick to fit the current window frame. The glazier is able to solve this problem by making a few adjustments depending on the material.

Wooden window frames

The majority of wooden frames will not cause a lot of trouble. A wooden frame is in most cases thick enough to store insulated glass. An option to solve potential problems is to mile the window seal or utilize thinner glass beads. 

Winding wooden window frames

Adjustments to wooden frames that have the ability to turn are more complicated. The level of difficulty depends on the state and thickness of the window frame.

Insulated glass outweighs single glazed windows. Due to this, extra pressure is applied to the hinges. Therefore, it is important that the hinges can handle the new windows. 

Synthetic window frames

Synthetic windows frames fit like a puzzle, all the glazing beads are adapted to one another. Some producers of frames produce 'click frames', which enable you to create additional space for the insulation glass in the existing window frames. 

Aluminum frames

Special glazing beads are available for certain aluminum windows frames in order to place insulation glass in an existing window frame. An alternative is opting for a different type of glass frame that suits your window or order a custom made click frame from your supplier.

Steel window frames 

The manufacturing of click frames is also an option for steel window frames. Click frames are delivered ready-to-use, and instantly being implemented in the steel window frame. 

What if your window frames are unsuitable

The majority of windows can be, with or without adjustments, used for insulation glass. The costs for the adjustments of your window frame are usually included in the total price of placing the insulation glass. it is advisable to check this with your glazier.
