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
A popular choice for heritage homes, Slimlite is a discreet, ultra-thin double glazed unit designed to replicate the look of traditional single glazing. Despite its slim profile (as little as 10mm), it provides excellent thermal and acoustic performance.

- Low-E coated glass
- Argon gas filled
- Warm edge spacer options
- Approved by many local planning authorities
- Compatible with traditional glazing bars and putty finishes
- Perfect for single to double glazed upgrades and conservation-sensitive settings.

High-performance, modern comfort
For properties without conservation restrictions, we offer full-thickness double glazed units with outstanding energy efficiency. These units are commonly used in new joinery projects or where planning allows for enhanced thermal performance.
- Choice of cavity widths
- Argon or krypton gas fill
- Low-emissivity (Low-E) glass
- Acoustic laminate available for sound insulation
- Toughened safety glass options for ground floors and bathrooms

- Privacy without sacrificing style
Ideal for bathrooms, cloakrooms, or side elevations, we offer a variety of obscured and patterned glass styles to suit both traditional and contemporary tastes.
- Sandblasted and etched glass
- Textured and rolled patterned designs
- Classic options like Flemish, Stippolyte, and Minster
- Available in both single and double glazed formats
- Can be combined with safety laminates or toughened glass
- Acoustic Glazing
- Peace and quiet, even in busy locations
If your home is located on a main road or near high foot traffic, acoustic glazing offers a subtle yet effective way to reduce noise. These units use specialist interlayers or thicker panes to dampen sound vibrations without affecting appearance.
- Available in Slimlite or standard profiles
- Ideal for bedrooms and living areas
- 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:
- Toughened safety glass: Stronger and shatters into blunt fragments
- 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
