Thermally Insulating Glass

Save on energy bills and reduce your carbon footprint with our high-quality thermally insulating glass. Suitable for windows, French doors, and patio doors alike, the glass is purpose-designed to create interiors that remain at a comfortable temperature year-round. Thanks to our additional foils and coatings, you can make the panel your own by adding a stylish finish, or by enhancing soundproofing and optimising break-in protection. Just keep reading or head to the configurator to find out more.

Why Purchase Thermal Glass?

  • Although the glass comes with higher initial costs, in the long run it will result in utility bill savings
  • It can create windows and doors suitable for builds aiming to achieve Passive House Institute certificates for excellent energy efficiency
  • Less energy is lost, which also helps to preserve natural resources and lower carbon footprint
  • Thermal glass allows products to meet local regulations and attain planning permission
  • Large, glazed patio doors and dimensions can be purchased while interiors retain heat

The Key Features of Thermal Glazing

  • Insulating glass works to lessen heat loss via conduction. 
  • The panel therefore features technical parts that minimise the temperature difference between the glazing and the surrounding air:

 

1. Multiple Panes

Thermal glazing features multiple sheets to increase the panel’s thickness and reduce heat emission via conduction. At windows24.com two panes can be used as double glazing for good standard insulation or a third can be added for optimised triple glazing.

2. Spacers & Desiccant

We offer two double-glazed options and two triple-glazed variants. These differ in terms of energy efficiency. The option offering the higher degree of insulation features larger spaces between the panes. The spaces are set by spacers made from a low-conduction material.

3. Sealed Argon

The spaces between the sheets of our insulating glass are filled with argon gas. This unreactive gas is denser than air, so slows energy loss to a greater extent. The glass is well-sealed to with quality rubber glazing gaskets to ensure a tight fit.

4. Low-e Coating

Our glass is finished with an invisible low emission (low-e) coating. Made from a metal oxide like silver, the coating reflects UV and infrared radiation that could otherwise cause interiors to become too warm. Because visible light has a different wavelength, its entry is not restricted.

Combine Insulating Glass with Premium Profiles

To purchase truly efficient windows or doors, a thermally effective profile and frame material can be purchased for your new or replacement product and be paired with the insulating glazed panel. Our experts particularly recommend uPVC. This is because this modern material features multiple chambers that trap air to prevent heat loss. Certain profiles like energeto 8000 ED then also feature three seals and purpose-designed integrated insulation foam for improved thermal properties.

Profiles like the energeto 8000 ED, paired with triple glazing, can achieve u-values as low as 0.74 W/m²K, which aligns with the Passive House Institute’s requirements for excellent energy efficiency.

Tailor the Panel to Suit Your Needs & Style

  • Our insulated panels for windows and doors can be adjusted to provide enhanced performance in further areas:

To achieve desired soundproofing and create peaceful interiors, invisible “silence foil” film layers can be inserted between the sheets. This slows the travel of sound waves and can reduce noise by up to 45 dB, which can be suitable for properties located as close as 300 m from an airport.

To enhance break-in protection, wind resistance, and safety, PVB polymer film interlayers can be inserted during production in a lamination process, or the panel can be tempered. These professional techniques increase impact resistance and pressure deflection, which makes products ideal for high wind zones or coastal areas. The thicker surface also makes it harder for intruders to break in. If the panel is broken though due to high force, it will not shatter into sharp shards. Instead, blunt crumbs will form, or the pieces will remain held on the intact laminated foil beneath.

Our windows and doors can feature various surface finishes. An ornamental option like Cathedral Small can be chosen, for example, to add interest and character to the property’s interior and exterior alike. To create secluded spaces that are shielded from onlookers, we also offer a range of frosted variants like Chinchilla or Satinato.
