Available Thermal Glass

Choose extreme-heat ceramic glass for direct flames (log burners) or toughened glass for indirect heat (splashbacks and oven exteriors).

Thickness Guide

Choosing the correct gauge ensures your glass sits safely inside the stove frame without cracking under expansion.

4mm

The standard thickness for most domestic log burners, wood stoves, and oven doors.

5mm

A heavier gauge ceramic glass used in larger commercial stoves and extensive fireplace screens.

6mm

Typically used in toughened (400°C) form for large kitchen cooker splashbacks.

Stove Glass Thickness Options

Edge Profiling

Because stove glass sits entirely inside a metal retaining frame, standard clean cut edges are typically recommended.

Clean Cut Edge Stove Glass

Clean Cut (Standard)

The glass is scored and snapped cleanly. Edges are left raw as they will be fully concealed and protected by the stove door’s retaining clips or frame.

Polished Edge Stove Glass

Flat Polished Edge

Edges are machined smooth with safety chamfers. Ideal for bespoke fireplace screens or outdoor fire pits where the edge of the glass is exposed.

Precision CNC Fabrication

Many older log burners feature non-standard, curved door panes. We provide advanced CNC shaping to recreate these specific panels.

✓

Arched Tops

Precision curved top edges designed to fit traditional cast iron stove doors perfectly.

✓

Clipped Corners

Diagonal cut corners (chamfers) often required to bypass internal hinge and handle mechanisms.

✓

Cutouts & Notches

Edge notching to fit your glass flawlessly around specific hardware or thermostat gauges.

Measurement Protocol

Perfectly fitting glass prevents cracking from metal expansion. Measure your stove door carefully before placing a custom order.

How to Measure Stove Glass
1
Measure the Old Glass

If your old stove glass is still intact, simply measure its height and width accurately with a metal tape measure.

2
Measuring the Door Frame

If the glass is completely shattered, measure the tight inner opening of the metal door frame where the glass sits.

3
Factor in Expansion Clearance

Deduct 3mm to 4mm from your tight frame measurements. Cast iron expands when hot; if the glass is too tight, it will crack.

4
Submit in Millimeters (mm)

All custom glass orders are processed and manufactured strictly in millimeters.

Engineered for Fireplaces

Extreme Endurance

Withstands thermal shock up to 800°C without shattering.

Frequently Asked Questions

What types of heat resistant glass do you supply in the UK?

We supply specialist ceramic glass (such as Neoceram or Schott Robax) which is specifically designed for wood-burning stoves and fireplaces, as well as heat-resistant toughened glass for ovens and splashbacks.

What is the difference between ceramic stove glass and toughened glass?

Ceramic glass can withstand extreme thermal shock and constant temperatures up to 800°C, making it safe for direct flames in log burners. Toughened glass is heat-resistant up to 400°C, which is ideal for cooker splashbacks or exterior oven doors, but it will shatter if exposed directly to stove flames.

What thicknesses are available for stove and heat resistant glass?

Ceramic stove glass is standardly supplied in 4mm or 5mm thicknesses to fit almost all wood burner models. Toughened glass for high-heat areas is usually 4mm or 6mm.

Can you cut replacement stove glass to a custom size or shape?

Yes, we cut heat resistant glass to exact custom measurements. If your stove door requires a shaped panel (like an arched top), simply provide a template or exact dimensions.

Are the edges of replacement stove glass polished?

For stove glass that sits fully inside a metal frame or retaining clips, we provide a clean cut edge. We can also provide a Flat Polish edge if any part of the glass is exposed or if requested.

Is this glass suitable for an outdoor fire pit?

Yes, our ceramic glass is perfect for outdoor fire pits and bespoke fireplace screens as it handles direct, intense heat without cracking.

Do I need special seals when fitting my replacement stove glass?

Yes, we highly recommend replacing the thermal rope seal when installing new stove glass to ensure an airtight fit and to prevent the metal frame from expanding and cracking the new glass.

How do you pack and ship heat resistant glass?

Because stove glass panels are usually smaller, they are heavily wrapped in protective packaging and shipped securely in sturdy boxes via our trusted courier network to prevent breakage.

What is the usual delivery time for heat resistant glass orders?

Standard replacement stove and heat resistant glass orders typically take 5-10 working days to be cut, processed, and delivered across the UK.

Which UK areas do you deliver heat resistant glass to?

We offer flat rate delivery across England. Delivery to addresses in Wales and Scotland is also available, though additional shipping charges may apply.
