Conservatories

Introduction

Upgrading your home with double glazing or adding a conservatory is one of the smartest ways to boost comfort, energy efficiency, and property value. Whether you’re looking to keep your house warmer in winter, cut down on energy bills, or create a stunning new living space filled with natural light, this guide covers everything you need to know—from choosing the right styles to planning, installation, and long-term care.

What is Double Glazing?

Double glazing means fitting windows with two panes of glass separated by a gap (often filled with inert gas). This design dramatically improves insulation, reduces noise, and helps keep your home quieter and more comfortable.

Key Benefits:

Energy efficiency: Keeps heat in during winter and blocks excess heat in summer, reducing heating and cooling bills.
Noise reduction: Great for busy roads or urban areas—enjoy a more peaceful home.
Condensation control: Less moisture build-up on the inside of windows.
Security: Toughened glass and modern locks boost safety.
Low maintenance: No more annual painting or draughty old frames.

Double Glazing Options: Styles & Materials

uPVC frames: Affordable, low-maintenance, and available in a range of colours and finishes.
Aluminium frames: Sleek, slimline, and ultra-durable—ideal for modern homes.
Timber frames: Traditional look, great for period properties (requires more upkeep).
Composite: Combines timber and aluminium for the best of both worlds.

Popular window styles:

Casement: Hinged at the side, opens outward—classic and versatile.
Sash: Slides vertically—perfect for period homes.
Tilt & turn: Opens inward for easy cleaning and ventilation.
Bay & bow: Adds space and floods rooms with light.

Conservatories: Bring the Outdoors In

A conservatory is a glazed extension, usually at the back or side of a house, perfect for enjoying the garden all year round. It’s an affordable way to add living space, natural light, and value to your property.

Top Uses:

Light-filled lounge or dining area
Home office or creative studio
Playroom or garden room
Indoor plant haven

Types of Conservatories

Victorian: Elegant, curved front, ornate roof—timeless and classic.
Edwardian: Square or rectangular, maximises floor space, simple rooflines.
Lean-to: Modern, minimalist, and ideal for smaller spaces or bungalows.
Gable-end: High, upright front for a dramatic, airy feel.
P-shaped/T-shaped/L-shaped: Combines styles for larger, flexible spaces.

Materials:

uPVC: Most popular, easy to maintain, wide range of colours.
Aluminium: Strong, slim frames, perfect for contemporary looks.
Timber: Beautiful in heritage homes, but needs regular care.

Roofing options:

Glass: Lets in maximum light; choose self-cleaning or solar-control glass for comfort.
Polycarbonate: Cheaper, lightweight, but less insulating.
Solid/tiled: Converts your conservatory into a true extension—great for year-round use.

Planning Permission & Building Regulations

Permitted development: Most conservatories and double glazing replacements don’t need planning permission if they meet certain size and placement rules.
Building regs: Must meet energy efficiency and safety standards—always use a FENSA or CERTASS-registered installer for windows and doors.
Listed buildings/conservation areas: Special rules apply—always check with your local authority.

Energy Efficiency & Comfort

Low-E glass: Reflects heat back into the room, keeping you warmer.
Argon-filled units: Improved insulation compared to air-filled.
Trickle vents: Allow controlled ventilation to reduce condensation.
Thermal breaks: Essential in aluminium frames to prevent cold bridging.

Tip: Upgrade to triple glazing or laminated glass for even better insulation and security.

Maintenance Tips

uPVC/aluminium: Wipe frames and glass with soapy water; check seals and hinges annually.
Timber: Repaint or stain every few years; check for rot or flaking.
Conservatory roofs: Clean gutters, check for leaks, and clear leaves or debris.
Locks and handles: Lubricate moving parts to keep them working smoothly.

Costs & Value

Double glazing: Prices vary by size, material, and installer. Expect to pay more for aluminium or timber than uPVC.
Conservatories: Costs depend on size, style, and materials—lean-to is usually cheapest, bespoke designs cost more.
Value added: Quality double glazing and a well-designed conservatory can boost your home’s value and appeal to buyers.

Design & Styling Ideas

Blinds and shades: Control light and privacy with pleated, roller, or perfect-fit blinds.
Underfloor heating: Keeps your conservatory cosy year-round.
Bi-fold or sliding doors: Create a seamless flow between indoors and garden.
Greenery: Fill with houseplants or citrus trees for a true garden room feel.
Furniture: Choose weather-resistant or rattan pieces for a relaxed vibe.
