The Ultimate Guide to Choosing a uPVC Conservatory: Everything You Need to Know

Are you thinking about adding a conservatory to your home? A conservatory can provide a lovely space to relax in and enjoy views of your garden. When it comes to choosing one, uPVC (unplasticized polyvinyl chloride) is a top option. uPVC conservatories are affordable, durable, and energy efficient. This guide will walk you through everything you need to know when choosing a uPVC conservatory for your home.

What Exactly is a uPVC Conservatory?

A conservatory is essentially a glass garden room attached to a house. uPVC is the material used to make the frames and roof. uPVC is a versatile, weatherproof plastic often used for window frames, gutters, and plumbing. For conservatories, uPVC provides a long lasting, low maintenance option. It doesn’t rot or corrode like wood and resists fading or discolouration better than cheaper PVC alternatives. A uPVC conservatory has glass walls and roof to let in natural light. The floors, doors, frames and roof bars are made from uPVC in white or a colour to complement your home.

Benefits of a uPVC Conservatory

There are many great reasons to choose a uPVC conservatory:

  • Affordable – uPVC is cheaper than wood or metal alternatives
  • Durable – Lasts over 25 years with little maintenance
  • Energy efficient – Insulated frames prevent heat loss
  • Low maintenance – Doesn’t need painting or treating
  • Customisable – Range of styles, colours and glazing

Drawbacks of uPVC Conservatories

uPVC conservatories do have some downsides to consider:

  • Can fade over time, especially dark colours
  • Can be prone to condensation without adequate ventilation
  • Less aesthetic appeal for period properties than wood
  • Limited colour choice compared to aluminium frames

Key Factors to Consider When Choosing a Conservatory

When deciding on your perfect uPVC conservatory, there are several key factors to think about:

Size and Layout

Consider how you’ll use your conservatory and how much space you need. Popular styles include:

  • Lean-to: Simple square or rectangular addition
  • Victorian: Iconic bay front with faceted end
  • Edwardian: Square or rectangular with flat front
  • Gable end: Triangular roof sloping back to house wall

Make sure to think about access, views and sunlight too when planning the size and layout.

Frame and Roof Type

uPVC frame choices affect appearance, insulation and cost. Consider:

  • Number of roof angles
  • Ridge capping for an ornamental roof peak
  • Decorative finials, cornices and cresting


Conservatory glass types include:

  • Clear glass – cheap but poor at insulation
  • Toughened safety glass – Added security
  • Double glazing – Draught proof, energy saving
  • Solar control glass – Prevents overheating

Ventilation and Temperature Control

To prevent a conservatory becoming too hot in summer or cold in winter, ensure adequate ventilation and glazing options:

  • Roof vents
  • Fans
  • Air conditioning
  • Heaters
  • Blinds


Pick doors to match your frames. Options include:

  • French doors – Stylish access to the garden
  • Bi-fold or sliding doors – Open up space
  • Patio doors – Classic wide opening to deck or patio


Personalise with:

  • Colour to match existing paintwork
  • Bricks or coloured panels around lower walls
  • Internal dwarf walls for planting or display shelves
