Glazing Options for Timber Sash Windows
Glazing Options Designed to suit your property, performance needs, and personal taste
At Cavendish & Cole, we offer a full range of glazing options to complement our bespoke timber sash windows and restorations. Whether you’re upgrading to double glazing, renovating a listed building, or enhancing privacy with obscured glass, we’ll guide you through the best choice for your home.
All our glazing is selected for quality, energy efficiency, and visual compatibility with period-style joinery. We work closely with homeowners, architects, and conservation officers across Sussex, Kent, and Surrey to deliver beautiful results—inside and out.
Slimlite Double Glazing

- Can be combined with other features like obscured or Low-E glass
- Safety & Security Glazing
- Enhanced protection where you need it most
For added security or to meet building regulations, we offer safety glass options that do not compromise on appearance:

- Laminated glass: Resists impact and stays intact if broken
- Ideal for low-level glazing, doors, and areas accessible to children
- Specialist Heritage Glass
- Keeping historic charm intact
We can source and install hand-drawn or cylinder glass to match the ripples and irregularities of antique glazing, perfect for historically sensitive projects or full restoration work.
- Authentic appearance for listed buildings
- Matches Georgian and Victorian period styles
Can be combined with Slimlite for invisible performance upgrades

Discreet double glazing designed for traditional sash windows When it comes to upgrading sash windows in period or listed properties, finding a glazing solution that delivers energy efficiency without compromising aesthetics can be a challenge.
All our glazing is selected for quality, energy efficiency, and visual compatibility with period-style joinery. We work closely with homeowners, architects, and conservation officers
Living in a bustling town, near a main road, or under a flight path doesn’t mean you have to sacrifice peace and quiet—nor the classic style of your sash windows.
Privacy glazing is a common requirement in bathrooms, cloakrooms, and entryways—but standard modern options often look out of place in traditional homes. That’s why we source a range of authentic obscured and patterned glass styles that work in harmony with Georgian, Victorian, and Edwardian architecture.
If you're renovating a period home or looking into sash window repairs or replacements, you’ll quickly come across a number of technical terms — some of which can sound confusing at first.
