Primer on Window Sashes and Sash Components, Part 2

In part one of this two-part blog series, we went over some basics to be aware of when it comes to window sashes and their various components. The sash covers the window pane and all related features, and both single- and double-hung windows will come with two sashes.

At Peach Building Products, residential windows and all their components are one of our several specialty areas, which also include entry doors, patio doors and various additional window replacement services. In today’s part two of our series, we’ll go over a few additional component areas it pays for home or business owners to be aware of when selecting window sashes and overall window themes.

Glass (Glazing)

One of the single most vital parts of any window and window sash is the glass itself, which in the industry is often referred to as glazing. For instance, you’ll often see terms like single-, double- or triple-glazed window – these simply refer to how many layers of glass are being used.

Generally speaking, more panes means a more efficient window. Window sashes with multiple frames, naturally, tend to be a bit pricier than those with just one.

Gaskets

In modern windows, the glass itself will be sealed into the window frame on the sash using gaskets. These gaskets are made from rubber of thermoplastic vulcanizates (TVPs), and are in place to improve efficiency, prevent rattling and keep double- or triple-glazed windows set at the proper distance apart from each other.

Tilt Sash Release

Today’s double-hung windows are often built using a tilt-in design that allows them to open inward. In these cases, a tilt sash release will be required – it engages this function and allows this opening, making it easier to operate and clean windows from inside the home without risking safety.

Muntins

Some have never heard this term before, but you’ve almost certainly seen muntins on windows. They refer to thin grilles that are placed in windows to break the pane up into smaller visual segments – they hold little practical purpose, and are almost completely aesthetic. They are not to be mixed up with mullions, which separate adjoining windows using a thicker material.

Gas Fill-In

Finally, for double- and triple-pane windows types, there will often be what’s known as a gas fill-in included. This fill-in, usually made using argon or krypton gas (both are completely safe), helps increase insulation capability between the glass panes themselves, often in major ways that limit temperature loss and benefit your HVAC system throughout the year.
