While conceptually doors have been around since the early stages of architecture, their designs, functions
Our windows are available in a number of practical and attractive options. From tempered safety glass, to obscure glass for added privacy, we have a wide variety of colours, designs and textures to meet your custom window requirements.
No matter which glass options you choose, every EuroLine product is performance focused. All of our windows come with insulating glass consisting of two 4 mm panes, one with soft coat Low Emissivity Glass, and argon gas between them to improve thermal resistance.
Our products come in a range of energy saving designs, so be sure to speak with our product consultants to get the most energy efficient glass for your particular needs.
Clear glass allows natural light to show without distortion, provides maximum light transmission, and can be tempered for use where safety glass is required.
Low Emissivity (LoE) Glass reduces wintertime heat loss from inside your home due to a thin, nearly colorless metallic coating that reflects heat back into your home. It also allows moderate solar heat gain while reducing harmful ultraviolet light which can damage drapes, furniture, and carpets. Additionally, the LoE coating reduces summertime air conditioning loads by reflecting radiated heat outside your home.
While there are many different LoE coating options, it is available in two basic types: soft coat or hard coat.
Soft-Coat LoE, or sputter coating, is applied in multiple layers of optically transparent silver sandwiched between layers of metal oxide in a vacuum chamber. This process provides the highest level of performance and a nearly invisible coating. Soft-coat offers high visible light transmission, ultra-low emissivities giving optimum winter u-factors, and up to 70% less UV transmission compared with standard clear glazing. All EuroLine products come standard with a soft-coat LoE.
- The LoE allows most natural light to enter freely but absorbs a significant portion of short-wave heat energy.
- In the summer, long-wave heat energy radiating from objects is reflected back outside, lowering cooling costs.
- In winter, internal long-wave heat energy is reflected back inside, lowering heating cost.
Hard Coat, or pyrolitic coating, is a coating applied at high temperatures and sprayed onto the glass surface. This coating is relatively durable, which allows for ease of tempering. Hard coat LoE can be tempered for increased safety after the coating application. However, it has higher u-values, resulting in reduced thermal performance, compared to soft coat LoE. Also, hard coat LoE has higher haze levels compared to soft coat LoE, resulting in a less attractive appearance.
LoE coatings can be combined to achieve the desired combination of insulation and solar heat gain.

“Using gases such as argon and krypton between the glass surfaces can greatly improve thermal resistance. LoE gas-filled windows are so effective that attention is now focused on the edge of the IG unit and the window frame as thermal weak points; improvements include thermal breaks in metal frames, greater use of wood and clad wood sash and frames, or the use of lower conductance frame materials like vinyl. On a winter day in a northern exposure ‘superwindows’ actually achieve a net heat gain, contributing more useful solar heat gain than conductive losses.”
