Understanding Windows Glazing

Window Materials Matter

Well maintained timber windows with proper installation and maintenance can last centuries. It’s a testament to the refinement and texture of wood that Georgian sash windows are still present in many cities.

Windows add character to a building through their aesthetical beauty and history. Not only do wood windows impact the external kerb appeal of properties through their shape, size, position and materials, but they also influence the internal design of rooms.

The Importance of High-Quality Windows

The decision-making process of windows and doors can be quite overwhelming. Their style, efficiency and quality play an essential role in customer lifetime satisfaction. Important areas, such as the daylight entry, can make a noticeable difference in heating savings and overall comfort of the house.

Poorly insulated windows can lose up to fifteen percent of the heat inside the house. The U-factor value of a window determines the amount of heat that drifts in and out of the glass.

Essentially the lower the U-value, the less heat that will escape. Cardinal Windows are manufactured and tested to BSEN Standard 14351 (CE Marked), offering a whole window U-Value (Uw) of 1.5W/m2K.

What about double glazed windows?

The glazing indicates how many panes of glass are within the window frame. Double-glazed windows consist of two panes of glass separated by a space that is filled with either air or eco-friendly gases such as argon and krypton.

Cardinal offers windows with double strength Low-E insulated glass with Argon gas as standard to maximise thermal efficiency all year-round.

Double glazed windows consist of the following components:

  1. A Desiccant: This is a silicon material that is applied to the spacer bar in order to eliminate moisture stuck within the gap.
  2. A Primary Seal: This is the main barrier against air or moisture transfer into the double glazed unit.
  3. The Secondary Seal: This is the main structural adherent around the outside edge of the window, holding all the parts together.
  4. The Gap: This is the void formed between the component parts.
  5. The Gas: This fills up the gap, which can be either dehydrated air or eco-friendly gas, such as argon, krypton or xenon.
  6. The Spacer Bar: This is a frame that separates the two panels of glass, creating a gap.

Cardinal High-Performance Sliding Sash Windows

Cardinal Window’s Low-E glass is layered with microscopic coatings that cut UV transmissions with virtually no impact on the clarity or colour of daylight entrance.

Sash Fasteners

Cardinal applies a hermetically-sealed system for optimum insulation from heat, cold and sound. When the windows are produced, a low-conductivity spacer is used to separate the two panes of glass. The space between the two panes is then filled with an argon gas blend which helps minimise thermal transfer.

I ordered 15 sliding sash windows for my home refurbishment project and had my builder install the windows for me. I think I spent hours playing around with the different design options on the window builder! I absolutely love my new windows!
