Triple Glazed Windows - Key Features
Ideal for both contemporary and traditional homes, triple glazed windows offer outstanding durability, improved security and lower energy bills, making them an increasingly popular choice for homeowners looking to maximise performance without compromising on style.
Superior Thermal Efficiency
Reduce heat loss through your windows by up to 60% compared to standard double glazing. Regency Triple® helps keep your home warmer in winter, cooler in summer, and can significantly lower heating bills while improving overall energy efficiency.
Year-Round Comfort
Advanced triple glazing minimises heat transfer, creating a more consistent indoor temperature throughout the year. Enjoy a comfortable living environment regardless of the season.
Enhanced Home Security
Choose laminated glass for increased strength and security. Its tougher construction provides an additional layer of protection, helping to deter break-ins and improve peace of mind.
UV Protection for Interiors
Laminated glass blocks up to 99% of harmful UV rays, helping to protect furniture, flooring, artwork, and soft furnishings from fading caused by prolonged sun exposure.
Outstanding Acoustic Performance
Acoustic laminated glass significantly reduces external noise, creating a quieter, more peaceful home. Ideal for properties near busy roads, schools, railways, or airports.
Reduced Condensation
By keeping the inner pane of glass warmer, Regency Triple® helps minimise condensation on windows. This reduces the likelihood of mould growth and contributes to a healthier indoor environment.
Colour Options to Suit Every Home
Your triple glazed windows should complement the style of your home perfectly. At Walkers Windows, we offer a wide choice of contemporary standard colours and finishes, with the flexibility to match your aluminium frames to any RAL colour for a truly bespoke appearance.


















Triple Glazed Casement Windows Built to Last
Old-fashioned triple glazing meant adding 50% to the weight of a sealed unit. This extra weight could often compromise the design of casement windows. Due to the minimal weight impact of the micro-glass incorporated into our new sealed units your casement windows can still be hinged at the top or the side, providing you with all the flexibility you need, whether you choose double or new triple.
Walkers Windows triple glazed casement windows come with the same Yale locking mechanisms, hinges, dog bolts, and locking handles as the double-glazed options. All the hardware meets strict Secure by Design standards. The minimised weight in the triple glazed option allows your windows to be configured to maximise your views, allow excellent airflow and achieve excellent energy efficiency.
All Walkers’ windows are manufactured to the most exacting standards using only the highest quality materials and with a range of uPVC colours and glazing options they provide the right option for every home- from contemporary new builds to charming period homes.
Triple Glazed Windows FAQs
Choosing new windows is an important decision — and we know you might have a few questions along the way. To help, we’ve answered some of the most common queries about our casement window installation service.
How long does casement window installation take?
Most windows take around 1–2 hours each to install, depending on size and access. A full property can usually be completed in 1–2 days with minimal disruption.
Do I need planning permission to replace my windows?
Not usually. If you’re replacing windows on a like-for-like basis in a standard property, planning permission isn’t required. However, properties in conservation areas or listed buildings may have restrictions — we’re happy to advise.
Are your windows energy efficient?
Yes. All our double glazed windows are A-rated as standard, featuring multi-chambered frames and advanced glazing, but if you want to surpass A-rated choose our new Triple Glazed options.
Can I choose the colour and finish?
Definitely. We offer a wide selection of colours and finishes, including white, grey, black, woodgrain textures, and custom RAL options to perfectly suit your property.
What security features do your windows have?
Our casement windows come with robust multi-point locking systems and use components approved by the Secured by Design initiative — giving you peace of mind as standard.
