Glass doors

Glass doors are the stars among doors: they open up rooms and perspectives. Glass doors give light to living space. Glass doors open rooms.  They enable wide lines of sight and make living areas appear friendlier, brighter and larger. A revolving door made of glass is the optimal alternative to revolving doors made of wood.

Why glass doors? All advantages at a glance

  • daylight into every living space

  • rooms appear larger thanks to transparent room transitions

  • visibility protection through opaque matting nevertheless allows light into the room

  • certified safety with ESG and VSG glasses

  • creative interior design thanks to individual motifs on the glass door

  • durable, as less susceptible to scratches and wear

  • material without evaporation for more healthy living


Homely inspired

Glass doors are particularly suitable as room doors for noble and bright rooms - whether kitchen, living room, corridor or bathroom. By the way, replacing an existing wooden door with a glass door is very easy. For a revolving door even the existing frame can be used. With a glass sliding door, room transitions can be staged in a new way. That looks good and also saves space. In contrast to revolving doors, they do not need a pivoting range. Sliding glass doors run along the wall to save space. With a soft-closing variant you can treat yourself to additional comfort.

All glass doors from the GRIFFWERK range are available as revolving door systems or sliding door systems.

Spectacular white

Glass doesn't need to be green

Usually for an all-glass door soda-lime-silica glass is used. It has a distinct green tint. The reason for this is the iron oxide used for the glass melt. Depending on the light conditions, the green cast of the material is more or less visible. The brighter, whiter and clearer the interior design is, the more disturbing this discoloration is. Even in front of a plain, white wall, the difference is clearly visible. Especially in contemporary architecture, pure and high-quality materials are essential.

The pure difference

Glass door instead of wooden door? Of course you want to invite as much light as possible into your rooms. With PURE WHITE by GRIFFWERK, daylight can flow into the interior rooms unadulterated and colors, especially shades of white, come across clearly and unadulterated. White glass has been proven to be more translucent than the basic green variant. In a six millimeter thick glass door, light transmission is improved by about three percent. The gain in light has an even greater effect on large surfaces. The light that passes through is also pure and color-neutral. If you decide to use glass instead of wood for an interior door, the main reason is the gain in light.

Why White glass?

Our passion for glass began in 2014 when we designed our first collection of glass doors. Glass is a fascinating material because it is 100 percent recyclable. For the production of white glass PURE WHITE by GRIFFWERK, the iron oxide content is reduced to minimize the green tint. White glass has a special lighting effect and brings out the brilliance of decorations. That's why we have been processing white glass with finishing and printing processes since 2016, even at our headquarters in Blaustein in southern Germany - for a perfect result.


Fascinating Laser technology

Bundled light engraves delicate lines into the glass surface. Point by point and precisely controllable, detailed motives and finely graduated progressions can thus be transferred to glass. Our laser places microscopically small pixels next to each other, permitting photo realistic results. The deeper engravings change the light reflection. Laterally ingressing light makes the patterns virtually light up. Laser-processed glass doors remain transparent. If you wish more protection from looks, simply pick the version in TWO-SIDES with rear satination.

Light in its strongest form

Thanks to innovative laser technology, particularly fine and haptically attractive textures can be engraved on any glass door. The surfaces are durable and easy to clean.

Griffwerk laser doors meet ESG standard

GRIFFWERK offers tested safety for lasered glass doors made of single-pane safety glass ("TSG glass"). According to the German Institute for Building Technology (DIBT), the laser technology applied by GRIFFWERK fulfils all requirements. Since then GRIFFWERK is allowed to mark all glass doors with the TSG test stamp.

The stamp contains the number of the standard (DIN EN 12150) and is placed on the edge of the glass at GRIFFWERK in an optically unobtrusive manner on the hinge side. TSG is available from GRIFFWERK as green glass or in the high-quality white glass variant PURE WHITE by GRIFFWERK. Both glass types can be lasered and also meet the TSG standard when lasered.


Two sides of a glass door - "TWO SIDES"

Almost all all-glass doors in our range are also available in the translucent "TWO SIDES" variant. This will be processed from both sides: one side with laser decor, the other one flat satinized. So you can choose between two different versions of your favorite motif. The matt TWO SIDES variant offers more privacy.

By the way, our TWO SIDES option has nothing to do with the difference between "DIN left" and "DIN right" doors. All our models are available in both versions. If hinges and fittings are mounted on the left, we speak of "DIN Links" doors. If they are mounted on the right, they are "DIN right" doors.

Smoked glass MOON GREY

For glass doors we plead for white glass PURE WHITE by GRIFFWERK. Actually. But then we developed the new grey tones: Four new color shades that perfectly complement our product range.

The new MOON GREY glass reminds us of the countless soft shades of grey in moonlight. Laser technology engraves fine lines into the surfaces. SMOKED GREY is what we have called the clear glass version. In the TWO SIDES variant SATIN GREY, the door is fully frosted on the back and shields glances. Glass doors FROSTED GREY and FROSTED WHITE are made of high quality LSG PRIME glass and look particularly elegant due to the matting on both sides. FROSTED GREY owes its grey shade to a colored foil on the inside and is translucent. FROSTED WHITE is opaque due to a white foil on the inside.

VSG PRIME meets LASER

In the everyday life of a family, things can get a little rough. A glass door is then actually taboo - not with us: Because we have a solution with maximum protection in our offer. Laminated safety glass. First of all, there is the higher safety if glass breaks. The fragments adhere to the inner, tear-proof film, thus minimising the danger of injury. Additionally, our LSG PRIME glass doors are made of two connected ESG glass panes. They are characterised by crumbly fragmentation that prevents cuts. This is good to know. Safety comes first, especially for families. The decision to use LSG PRIME glass rightfully ensures a good feel.

LSG PRIME glass has plenty to offer aesthetically as well. The inner film can be coloured matte-grey smoky or even opaque. Colour tonalities in the interior can be controlled this way, and the desired degree of sight protection can be chosen freely. Now all laser patterns are avaliable on LSG PRIME.

Transparency

The GRIFFWERK-range offers most glass doors in two versions. In the TWO SIDES version, the door is fully matted on the rear to shield against looks.

Laser technology permits very fine engravings. They delicately draw through the glass surface. The course of the lines is permitted to vary: strictly lined up, compacting, overlaying or unevenly interrupted.

 


Reflecting gloss with glass doors

In VSG doors, a PVB-film is embedded between two ESG panes. This offers true additional safety: if the glass breaks, the shards will remain adhering to the film. Both sides are high-gloss and easy to clean. High-quality VSG doors also convince with better sound protection properties.

The high-gloss surfaces of the glass door design PIANO WHITE offer pure white reflection. They are a refined eye-catcher, especially in rooms designed in white. They also are an invitation to subtly play with the appearances of different surfaces.

We love the opposites of high-gloss glass in contrast with rough stone, natural wood or matte wall plaster. PIANO BLACK in deeply black glass is a special statement. VSG TRANSLUCENT is opaque but light-permeable as well.
 


How do I clean glass doors?

When you clean your interior glass, it is enough to clean the surface with warm water. For this, use a sponge or a soft, lint-free cloth. Clean a large area, rather than pointedly.

If there are residues such as fingerprints, you can also use commercially available glass cleaners (foam cleaners). Please do not use any scouring, caustic, acidic or alkaline cleaning agents, as these can attack the glass surface and cause scratches. Excess water can be wiped dry with a microfiber cloth. If water acts on the glass door over a longer period of time, stubborn lime residue can form.

For LSG doors, observe that the edge composite must not get into contact with water, since this may cause moisture and cleaning agent to enter the laminate. 

For satined and laser-treated surfaces
To avoid abrasion of the surface structure, you should not exert too much pressure here. In order to avoid the so-called cloud formation, rub your door with a microfiber cloth to dry a large area. Do not use paper or cellulose cloths. They have too much abrasion.

For screen-print glasses
Screen-printed surfaces are softer than the pure glass surface and therefore more sensitive against mechanical cleaning agents. They also must not be cleaned with acids since they may attack the print pattern.

Attention
Please do not use any scratching tools, razor blades or scrapers. They can leave visible and irreparable scratches on the surface.

FAQ

Why white glass?

White glass has a special lighting effect and brings out the brilliance of decors. For the production of white glass PURE WHITE by GRIFFWERK, the iron oxide content is reduced to minimize the green cast.

Why glass doors?

Glass doors allow natural daylight into every living space. Rooms appear larger thanks to transparent room transitions. A glazed door offers privacy through opaque matting, but still allows light into the room. ESG and VSG glasses offer certified safety. Individual motifs on the glass door create a creative interior design. Glass doors are durable, as they are less susceptible to scratches and wear. The material of the glass door has no evaporation and thus contributes to the health of the home.

Can a glass door be installed in a normal frame?

Yes. Existing frames for wooden doors can also be used for glass doors. When installing a glass door, it must be considered whether 2-part hinges or 3-part hinges should be used. To match the respective hinges, only the frame part has to be replaced, readjusted and screwed tight. After these steps, the glass door can be hung up without any problems.

Which frame for a glass door?

No specific frame is required for glass doors. Existing frames for wooden doors can also be used for glass doors. When installing a glass door, it is important to consider whether 2-part hinges or 3-part hinges should be used. To match the respective hinges, only the frame part has to be replaced, readjusted and screwed down. After these steps, the glass door can be hung up without any problems.

How do I clean glass doors?

With warm water and a sponge or a soft, lint-free towel. Clean large areas, not selectively.
In case of residues such as fingerprints, you can also use commercially available glass cleaners (foam cleaner). Please do not use any scouring, caustic, acidic or alkaline cleaning agents, as these can attack the glass surface and cause scratches. Excess water can be wiped dry with a microfiber cloth. If water acts on the glass door over a longer period of time, stubborn lime residue can form.
With laminated safety glass doors, make sure that the edge seal does not come into contact with water, otherwise moisture and the cleaning agent can penetrate the laminate.

How to clean LSG doors?

Glass is insensitive to acids, alkalis and solvents but is sensitive to scratches. Cleaning utensils should therefore be clean and soft. It is best to clean glass with plenty of clean water and a microfiber cloth or sponge. If necessary, commercial cleaners can be used. With laminated safety glass, care must be taken to ensure that the laminated film is not exposed to high levels of moisture. It is sufficient to simply dry it off so that any remaining moisture is removed.

TSG or LSG? Which is better?

Both glasses provide a safe living feeling. TSG is very robust and insensitive to impacts on the surface. When damaged, it breaks into small crumbs. This prevents deep, serious cuts. With a laminated safety glass door, all shards also stick to the composite film, comparable to the windshield of a car. The shards do not splinter into the room. The door continues to hang in its anchorage due to the extremely tear-resistant foil. Interior foils for laminated safety glass are so efficient that they are also used for burglar-proof glass and are even produced in bullet-proof versions. LSG Prime doors from Griffwerk combine the security properties of ESG and LSG.

When to use LSG?

Which glass variant is best depends strongly on the place of use. In highly frequented areas we would recommend LSG glass. Even if it is rather turbulent at home, e.g. because children romp around, it makes sense to invest in a higher quality laminated safety glass. It's definitely worth considering, because you will enjoy high-quality laminated glass doors every day and for years to come.

More security desired?

Who would like to arrange its dwelling as agefairly and barrier-poor as possible is with glass doors from laminated safety glass likewise well advised. We also recommend doors with large-area decors or matting on the back, as these are more visible. The purchase is worthwhile itself. It is always a good feeling to invest in a little more security and comfort.

What do LSG doors cost?

LSG doors are naturally more expensive than TSG doors. After all, the manufacturing process is much more complex. Those who have to pay more attention to the budget can only use laminated safety glass doors where a plus in safety is particularly important. This is the case in some rooms, such as staircases where there is a risk of tripping, in narrow corridors, in bathrooms (where floors can become slippery), at room transitions where there is a strong draught and generally wherever there are people in need of special protection, such as children or elderly people. In any case, only doors made of safety glass, whether toughened or laminated, should be used. We offer many designs in both types of glass.

How thick is LSG?

Usually it is 8.8 mm. However, the thickness of our LSG glass doors depends on the format. For larger formats we recommend a thickness of 10.8 mm.

Can LSG be cut?

No. Since our LSG glass doors are made of TSG panes, they cannot be cut. Due to the stress conditions in the single-pane safety glass (TSG), normal cutting wheels cannot be used. The glass would shatter. Later adjustment of your door is also not necessary. Griffwerk offers all common formats in its range. Special sizes can be ordered. It is best to use our practical measurement sheets to order your new glass door. So nothing can go wrong and everything fits perfectly.

Can LSG be lasered?

Yes, Griffwerk also refines LSG glass doors with laser decorations. The filigree surface engraving by laser looks particularly noble on this premium material. Numerous motifs are available to choose from. Let yourself be inspired and enjoy the added aesthetics and safety.

Which glass for room-high doors?

We recommend a thickness of 10.8 mm for larger formats. In principle, TSG or LSG doors with a thickness of 8.8 mm can also be installed. However, because of the height and the larger amount of glass, we would recommend a LSG door with a thickness of 10.8 mm. Room-high doors appear particularly spacious and provide an open living feeling. In LSG, they are particularly high quality.

Is laminated safety glass also available tinted?

Yes, of course, tinted glass can be processed into LSG doors. As a rule, however, special functional foils are used. The inner foil processed in a laminated glass door can be matt, opaque or colored and can even be printed with motifs. Double-sided frosted glass doors are particularly elegant. This is also possible with LSG glass.

Why use white glass for LSG doors?

The double-layer construction of a laminated glass door would also double the green tint in regular float glass. We therefore recommend color-neutral white glass PURE WHITE BY GRIFFWERK for glass doors made of laminated safety glass, especially if these are to be frosted over a large area, because the matting further emphasizes the inherent color of the material.

What is meant by residual carrying capacity?

In case of glass breakage, the fragments of a laminated glass door do not only adhere to the inner foil. The entire glass door remains stuck in the anchoring due to the high tear resistance of the foil. Thus, it does not fall to the floor and does not splinter into the room. Therefore, LSG is indispensable especially for overhead roofing. The residual load-bearing capacity naturally also increases safety in case of glass breakage in the living area.

How sensitive is LSG?

LSG Prime doors can withstand a lot. This is already due to the fact that they are made of two TSG panes. TSG has a much higher stability than normal float glass. For example, the bending strength alone is three times higher. The impact and shock resistance is also much better. These properties are achieved by thermal pre-treatment of the ready-cut TSG pane. The glass is heated and then cooled down relatively quickly. This creates two different stresses in the glass. There is compressive stress on the inside and tensile stress on the surface. Unfortunately, these stress ratios also have disadvantages, because TSG becomes very sensitive at the edges. The edges are actually the greatest weak point of a pane. This also applies to LSG doors.
