Description

Fire-resistant glass for fireplaces

Fire-resistant glass, most common applications: fireplace glass, fireplace glass – fireplace glass, stove glass and as technical glass in inspection hatches, etc.

The material we supply is a very high quality and rigorously tested 4mm thick ceramic refractory glass with a very low coefficient of thermal expansion. The glass is slightly yellowish in colour, but completely transparent.

We can also provide you with a fireplace glass in

refractory braids

In cold weather, it’s important to get your hatch glass in good condition without delay, so we aim to deliver fire-resistant glass as soon as possible as a top priority. # fire-resistant glass # fireplace glass # fireplace glass

Border grinding

Usually the edges of the fireplace glass are hidden, so no further sanding is needed. If the edges of the glass remain visible after installation, we recommend that you also apply a polish to the glass from the edges menu. In this case, the sharp edges of the glass are ground clean and polished. ready for presentation. Edge grinding also slightly increases the bending resistance of the glass. To add to the appearance, you can also choose to have the glass surface faceted at the edge or 45-degree faceted. When facet grinding glasses, if all corners of the glass are rounded with less than 11mm of angular curvature, the facet grinding is done in a straight line and does not follow the angular curvature. Otherwise, the facet is ground on a CNC machine to follow the edge line of the glass, including the rounding.

When ordering fire-resistant glass – if you do not choose edge grinding (cut only), we will always roughly strip the edges of the glass to blunt the sharp edges.

You can get your refractory glass cut to any of the above glass shapes (select shape), also available with holes drilled.

If you need corner spins

Examples of the size of angular rotations: the radius, or R, is the size of the circle of which the angular rotation is a part. Examples of what corner spinning can be compared to:

• The diameter of a long-playing LP is about 300mm, i.e. radius R=150mm
• The diameter of the CD is 120mm, i.e. radius R=60mm
• The diameter of a 2 euro coin is about 25mm, i.e. radius R=12.5mm
• The diameter of a 10 ct coin is about 20mm, i.e. radius R=10mm
• 3mm rounding (R3) the rounding is just visible to the eye from the corner of the round, but the shape of the glass is not yet substantially changed
• The 1mm rounding (R1) doesn’t look much like a rounded corner, but feeling it with your fingertip you can feel that the sharpness has just about disappeared.

Drilling a hole in the glass – you can also order holes to be drilled in the glass to your desired location. There are certain regularities in where holes can be drilled in the glass. For example, each glass thickness has its own minimum distances, the distance between the edge of a hole and, for example, the edge of the glass, the corner of the glass or another hole. These distances are larger in tempered glass than in untempered glass, and the distances increase with the thickness of the glass. There is also a minimum hole diameter depending on the glass thickness.

• Our calculator always automatically checks that these minimum distances are met and that the hole is not too small for the glass thickness.
• The holes are always rough-edged, i.e. the holes are supposed to go “hidden”.
• 6-40mm holes are generally drilled with diamond drills and holes over 40mm are either drilled or machined with CNC machines.
• There is no upper limit to the size of the hole, we can machine almost any size hole in the glass
• The holes can also be flush with the edges, making the so-called. half e.g. for cable penetrations, etc. or fireplace glass against a round fireplace
• 
• 
• The holes cannot be too close together, but the holes can partially overlap (min 1/3 part) – this will give you longer gaps. (Hole spacers may be machined straight if production possibilities so require)
• 
• If possible, always try to use the same hole size (cheaper)

Please note that refractory glass is not suitable for tempering (the tempering would break off the glass immediately after the first heating), so if you order glass with holes, you should be careful, for example when tightening screws through the holes.
