Our Sash Window Terminology Guide

If you’re thinking about wooden sash window replacement, you’ll want as much information as possible. As with any specialist product, a lot of the terminology will be unknown to most people. When you think of a window, you probably think it only consists of the frame and the glass. Add some handles and hinges, and that’s about it. When you hear sash window terminologies such as sash horns, mullions, and astragal bars, you’d be forgiven for thinking you were speaking a different language.

At Rose Collection, we want the best for all our customers. When a customer feels like they understand a product like uPVC sash windows, they are usually happier with their purchase. To help you know some of the more unusual sash window jargon, we’ve compiled a handy sash window terminology guide to ensure you’re fully informed.

Sash Horns

Initially used in timber sash windows to strengthen the joints, sash horns are a distinctive part of their appearance. Here at  Rose Collection, we often feature them in our uPVC sash windows range to replicate timber sash windows authentically.  

Consider either run-through sash horns as an integral part of the window or clip-on sash horns for a cost-effective alternative. Allowing you to add character to your sash windows, you can find this feature available in our Ultimate Rose uPVC sash window.

Transoms and Mullions

A transom is a horizontal beam that divides sash windows into sections. A mullion is its vertical counterpart. Originally used to support separate glass panes, they are now commonly used to replicate the traditional heritage style. 

 

Astragal or Georgian bars

Astragal or Georgian bars are a specific name given for the thin transoms and mullions used in heritage windows. Originally used in the Georgian era, they are a common feature in many historic or conservation area sash windows. For new builds, astragal and Georgian bars are also suitable. They are a great way of adding vintage character to your home through the addition of new uPVC sash windows.

What’s better is that all three ranges of our uPVC sash windows feature astragal bars so that you can incorporate your personal preferences and complement your property. Check out Charisma Rose, Heritage Rose or Ultimate Rose to add Astragal bars to your unique design, along with many other authentic optional features!

Meeting Stile and Rail

The meeting stile and rail – also known as midrail – are the sections of the window frame that support the structure. Without these, your sash windows would not be able to sustain the panes of glazing. It’s these features which help add strength and solidity to the uPVC frame. Without them, your new uPVC sash windows would not be able to be as thermally efficient or A rated as they are, as simply, the window frame would not be able to hold the double glazing panes. Designed specifically for true authenticity, consider our Ultimate Rose uPVC sash windows if you are looking for the slimmest meeting rail on the market.

Profile

The sash window profile refers to the sections of a window that are joined together to create the frame. Here at Rose Collection, we build our sash windows by using the finest uPVC profiles that offer homeowners a range of modern performance benefits.
