Casement Window Colours
With such a range of opening configurations and designs, casement windows are perhaps more popular than any other window. They are essential for projects in contemporary new builds, as much as for those in heritage properties and with commercial work. Our colour range accommodates every installation you may encounter, meaning you’d never need to turn work away.
Aside from the classic White and trending foils that include Agate Grey, Anthracite Grey, Sage Green and Pebble Grey, you can also specify your customer’s casement windows in one of several authentic woodgrains. We’re certain your homeowner will find the perfect one for their property, or your new build project will include windows that fit your vision.

Product Hardware
A window is only as good as the hardware which supports it. Here at Tradeglaze, we manufacture our casement windows for trade supply with only the highest quality components. Doing so allows you provide homeowners or other end users with peace of mind regarding the weatherproofing, security and longevity of the windows they are investing in.
Mulltipoint locking systems, sourced from industry leaders, come as standard. They are structurally sound enough to not require any lead reinforcement, something we’re immensely passionate about here at Tradeglaze. Our casement windows are designed with durable handles and heavy duty hinges to accommodate regular daily residential and commercial use, as well.

Superior Energy Efficiency
Our casement windows attain the best standards of energy efficiency. Whether you’re looking to have these windows fitted, supplied as part of a larger development project or anything in between, they’ll trap heat in during the colder months. Our own in-house glazing compliments a multi-chambered uPVC profile to reach U-values of just 0.8 W/m2K.
They manage such excellently low Window Energy Ratings by trapping heat within the home. In turn, this can result in cheaper energy bills for the end user. Stunning windows can create beautiful windows without it coming at the expense of poor energy efficiency. You get the best of both worlds with our uPVC casement windows.
