A Brighter & Warmer Space, Year-Round

Our Double Glazed Conservatories

A conservatory is more than just an extension – it’s a bridge between indoors and out, offering a bright, welcoming environment to relax, entertain or even work. At Estuary Windows Ltd, we design, supply, and install high-performance double-glazed conservatories tailored to suit your home and lifestyle. Types of double-glazed conservatories we offer include

Polycarbonate Conservatories – Affordable, Functional & Versatile

Ideal for homeowners seeking cost-effective space solutions, our polycarbonate conservatories offer durability and functionality. Featuring optional heat-stop polycarbonate roofing, they help preserve room temperature, making them more usable throughout the seasons without breaking the bank.

Glass Conservatories – Light-Filled Elegance

The classic choice, glass conservatories create a sense of openness and tranquillity with large double glazed panes that allow natural light to flood your space. We offer a variety of coloured frame options, enabling you to design a glass conservatory that complements your home’s personality.

SupaLite Tiled Conservatories – All-Year-Round Comfort

Our most popular option, the SupaLite tiled roof system, transforms your conservatory into a warm, insulated space that looks and feels like a true extension of your home. Complete with plastered ceilings and lighting options, these conservatories are perfect for dining rooms, offices, lounges and more – whatever you imagine, we can build.

From full replacements to bespoke installations – we do it all. No job is too big or small, and every conservatory we construct is completed to the highest standards using quality materials designed to last. Get in touch today to receive a FREE no-obligation quote from one of our friendly experts.

Why Double Glazed Conservatories? Discover the Benefits

  • Energy Efficiency
    Double glazing dramatically reduces heat loss and traps warmth inside during colder months, helping lower your energy bills and reduce your carbon footprint.
  • Increased Property Value
    A high-quality conservatory enhances your home’s kerb appeal and adds genuine value, making it an investment that pays off both now and in the future.
  • Year-Round Usability
    Say goodbye to too-hot summers and freezing winters. Double glazing, especially when paired with SupaLite tiled roofs, ensures your conservatory stays comfortable all year long.
  • Enhanced Natural Light
    Our conservatories are designed to maximise sunlight, reducing your reliance on artificial lighting and boosting your mood in the process.
