Casement Windows

Best for energy efficiency

Casement Windows – Best for energy efficiency

Casement windows are our most popular style of uPVC windows. And it is easy to understand why! They are a completely customisable window that will suit most homes, no matter where you live in Northern Ireland. 

Black or grey windows have become increasingly popular in recent years. These window frames are finished with a wood grain effect and can be designed with either triple or double glazing too!
A beautiful, low maintenance alternative to timber windows, and we can replicate most styles including Georgian bar windows.

Windows and doors can account for up to 20% of domestic heat loss. So when it comes to energy efficiency, our ‘A’ rated windows deliver exceptional insulation qualities in both double and triple glazing options.

Modern uPVC windows feature a multi chambered design which optimises thermal performance by preventing heat escaping from your home.

Coupled with our A-rated argon gas filled glazing units, your new windows will perform well year after year, and help save money on heating costs!

Our rigorous focus on quality extends to handles and hinges – after all, you want to be sure they will last the lifetime of the window. So in order to make sure they are up to the job, we test them to the highest possible standards. Consider this – our window handles are tested to 50,000 cycles. That is the equivalent of opening and closing them every day for 136 years!

At Budget Designer HomeWorks, we believe that security is paramount. Market-leading safety features such as Bear Grip Hooks are built into all of our casement windows.

As the strongest multi-point locking mechanism available, they significantly exceed the level of BSI security standards!

Our casement window range comes with a choice of safety and comfort options such as child proof restrictors, trickle vents and different handle options.

Available in a variety of colours, we even provide flush casement windows for a sleeker finish.

So if style, safety and durability are important considerations, check out our casement windows. Or simply book an appointment for one of our consultants to give you a no-obligation quote.

Efficiency Guide


All windows and doors are energy A rated as per the Energy Ratings labels. Our energy rated products help to contain and conserve heat within your home and also reduce your ‘carbon footprint’ by keeping out wind and rain and yet allowing natural ‘free’ energy to heat your home.

With carbon emissions high on the global agenda and the current high cost of fuel, we are all looking for ways to make our homes more energy efficient. You can save money on your energy bills and help to reduce emissions by installing energy efficient windows and doors.

The BFRC ratings scheme is the UK’s national system for rating the energy efficiency of windows and doors and is recognised within the building regulations as a method to show compliance for your installations.

Its rating scheme for energy efficient windows is a system that uses EU authorised energy labels, (specifically produced for windows and doors) that are similar to the energy labels seen on most household appliances.

All of Budget Designer HomeWorks range of doors and windows conform to British standards and windows and doors are all energy A rated. As well as this all our products incorporate maximum security iron mongery.
