Vertical Sliding Sash Windows

Warm and cosy

Sliding Sash Windows – Warm and cosy

The exquisite range of sliding sash windows from Budget Designer HomeWorks are amongst the most distinctive and authentic-looking sash windows available in Northern Ireland. 

Available in both aluminium and uPVC, our sash windows can be finished in any colour to match the aesthetics of both modern and traditional buildings. 

The classic window design of vertical sliders will enhance the timeless characteristics of your home whilst providing all the Industry leading specifications of modern uPVC.

The frames and sashes are mechanically jointed, which are much stronger than a welded joint and designed to offer unparalleled strength and security. 

A heavy bottom rail in the sashes allow symmetrical internal sightlines, mimicking the historical charm of heritage style homes.

Optional period features such as decorative or run through sash horns and Georgian or astragal bars help to capture the ageless elegance of historical architecture. 

We pay attention to the smallest details with period-style hardware and fittings such as thumb locking cam catches to replicate traditional timber sash windows, creating the most stunning effects.

Internal sash jammers restrict the opening to only 4 inches for added security – our windows are PAS 24 certified (police approved security).

Forget draughty sash windows of the past!  When it comes to performance, our ‘A’ rated glazing delivers exceptional insulation qualities in both double and triple glazed forms.
Keep the outside world outside, increase the energy efficiency of your home and save on heating bills whilst feeling safe, secure and comfortable.

So if style, safety and durability are important considerations, check out our sliding sash windows. Or simply book an appointment or visit our Bangor showroom 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.
