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.

Casement 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?

Yes. All of our casement windows are A-rated as standard, featuring multi-chambered frames and advanced glazing to help keep your home warm and your energy bills low.
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.
