Types of glass (and why they matter).

Replacing, updating or installing glass?

The type you choose matters more than you think.

Here’s how to get it right.

Not all glass is created equal. Whether you’re building, renovating, or replacing a single pane, the type of glass you choose affects everything.

From how your space looks and feels, to how it performs in heat, cold, noise, and privacy.

Here’s a quick guide to some of the most common glass types we work with, and why they might (or might not) be the right fit for your next project.

Single-glazed glass

What it is:

Just one single sheet of glass. Basic, functional, cost-effective, and very common in older homes.

Pros:

  • Affordable

  • Easy to install or replace

  • Works fine for interior glass (like mirrors or partitions)

Cons:

  • Poor insulation (both temperature and sound)

  • Not ideal for energy efficiency or security

  • Often no longer compliant for new external windows/doors

Best for:

Internal panels, simple furniture tops, and budget jobs where insulation isn’t a factor.

Double-glazed glass

What it is:

Two panes of glass with an air or gas-filled gap in between—this space acts as insulation.

Pros:

  • Stronger thermal and sound insulation

  • Reduces condensation

  • Can lower energy bills

  • Increases home value

Cons:

  • More expensive than single glazing

  • Heavier (may require different framing)

  • Can take longer to source or manufacture

Best for:

External windows, doors, shopfronts, and any situation where comfort and energy efficiency matter.

Energy-efficient glass (Low-E / EnergyTech)

What it is:

Glass with a special coating (like Low-E or EnergyTech) that reflects heat while still letting in light. Often combined with double glazing for best performance.

Pros:

  • Keeps heat out in summer and warmth in during winter

  • Improves energy efficiency without darkening the room

  • Helps with compliance in modern building codes

Cons:

  • Slightly higher upfront cost

  • Must be installed correctly (coating orientation matters)

Best for:

Modern builds, renovations aiming for energy compliance, or anyone wanting to reduce heating/cooling costs long-term.

Obscured / privacy glass

What it is:

Glass that’s been textured, etched, or treated to obscure visibility while still letting light through.

There are heaps of styles, including:

Frosted Glass: Soft, blurred finish—modern and clean

Fluted / Reeded Glass: Vertical ridged texture. Retro feel that's making a comeback.

Cathedral Glass: Wavy, decorative texture—found in older homes and churches

Satinlite / Acid Etched: Matte, milky surface with a soft finish.

Patterned / Printed Glass: Custom designs for something unique.

Pros:

  • Perfect for bathrooms, entryways, and shared spaces

  • Keeps natural light while protecting privacy

  • Adds style and texture to otherwise plain glasswork

Cons:

  • Some styles may date faster than others

  • Harder to match if replacing a single pane

Best for:

Bathroom windows, shower screens, front doors, laundry areas, or partitions between spaces that need light without full visibility.

Why does glass type matter?

Choosing the right glass isn’t just about aesthetics. It affects:

Comfort: Keep rooms cooler in summer, warmer in winter

Safety & compliance: Some glass types are required for high-risk areas

Noise control: Block out traffic, neighbours, or commercial noise

Privacy: Obscure what needs obscuring without switching to blocky walls

Style: The right texture or finish can completely transform a room
