From traditional to contemporary, our hardware comes in a variety of styles and colour finishes to complement your home’s architectural style and help achieve your home design goals.

Please note: Hardware options will vary depending on the material of your flush casement window. Filterable hardware options are coming soon.

Flush Casement Window Glass & Glazing Options

In addition to clear glass, flush casement windows can be fitted with any one of 30 etched glass or textured glass designs, each offering varying levels of obscurity to meet your privacy or style needs.

Please note: Glass options may vary depending on your window material.

For a heritage feel, decorative glazing bars (leaded bars, Georgian bars, and astragal bars) can also be mounted to your window panes in a variety of different configurations.

All truhouse. flush casement windows are double-glazed and A+ rated as standard, with the option to upgrade to triple-glazing or apply additional lamination and surface coatings that help control the amount of light and heat entering and leaving your home.

Understanding and choosing the right glass and glazing options will help ensure you’re investing your money wisely in windows that will give you both the look and the energy efficiency you require. Let us know what you’re looking to achieve and our friendly experts will assess your environment, discuss options, and advise the best glazing solution for you.

What are Flush Casement Windows?

Flush casement windows, less commonly referred to as flush sash windows, are hinged on one side of the frame and open outward with a push out motion/operation. Different to standard casement windows, the sash (the opening part of the window) sits flat (flush) with the surrounding frame.

Increasingly the popular choice for homeowners, flush casement windows blend traditional 19th century styling with modern performance, delivering a low maintenance, authentic look with the superior energy efficiency and security assurance that you should demand from new window installations.

With each and every window made to measure by our team of specialists and tailored to complement your property and personal taste, there are no limitations to the homes that our flush casement windows suit. Some of the properties that we’ve installed in include new build or modern homes, period or traditionally styled homes, conservation area (where timber or conservation approved uPVC windows are installed), and graded properties (where timber has been installed).

The choice is endless, as is our devotion to you and your household efficiency and security.

Safety & Security

In addition to frame composition and glazing, window safety and security is largely dependent upon the locking and hinge mechanisms fitted.

tru. security

Safety & Security

In addition to frame composition and glazing, window safety and security is largely dependent upon the locking and hinge mechanisms fitted.

Whichever window style you choose for your home, all truhouse. windows are composed of robust multichambered profiles and fitted with the latest high security multipoint locking mechanisms and metal anti-jemmy hinge bolts to prevent your windows being forced open. With each side of the opening sash fully secured with the turn of a handle or closing of a fastener, our windows ensure your home is protected against potential intruders.

High security fire escape hinges, also known as egress friction hinges, are fitted on hinged window units as standard, providing you with maximum clearance in the event you need to exit through your window in an emergency (dependent on window size).

Child safety hinges, known as tri-stay fire escape hinges, are also available on request, with a built in restrictor function to prevent children opening and falling out of windows (or even climbing in through open windows).
