What is Double Glazing?

Insulating Glass or Double Glazing consists of two or more panels of glass bonded to a perimeter spacer, either a metal or thermoplastic spacer. A gas, normally air or argon, fills the sealed space between the glass panes. Their primary benefit is insulation and solar control. Most types of glass can be incorporated into an insulating glass unit

What is Laminated glass?

Laminated glass is glass made by combining two or more layers of glass with one or more “interlayers” of polymeric material (special plastic) bonded between the glass layers. While the most common form of laminated glass is a safety glass, this is not always the case. A laminated glass may not be a safety glass but still provide some functional properties such as for decorative applications. Laminated glass is produced using one of two methods.

The most common method to produce both laminated glass and laminated safety glass is to use a polymer film (Poly Vinyl Butyral or PVB) sandwiched between layers of glass and processed using heat and pressure to bond the glass together. On occasion, other polymers such as Ethyl Vinyl Acetate (EVA) or Polyurethane (PU), Polycarbonates, PET films or ionomers are used. Laminated glass offers many advantages. Safety, security and glass shard retention are the best known of these. Rather than shattering on impact, laminated glass is held together by the interlayer, reducing the safety hazard associated with shattered glass fragments, as well as, to some degree, the security risks associated with easy penetration. The interlayer also provides a way to apply several other technologies and benefits, such as colouring, sound dampening, resistance to fire, ultraviolet filtering, solar control and other technologies that can be embedded in or with the interlayer.

Laminated glass is used extensively in building and housing products and in the auto-motive and transport industries. Most building façades and most car windscreens, for example, are made with laminated glass, usually with other technologies also incorporated.

How do you clean coated Low E glass?

This addresses the procedures for cleaning pyrolitic coated (hard coat) Low E glass. The presence of the Low E coating can be confirmed by using an electronic continuity tester or by touch. Low E coating feels noticeably rougher than the smooth glass surface. The following instructions will NOT harm ordinary uncoated glass. It is important to note the normal presence of a haze on some coated glass under some conditions. If encountered, consult the manufacturer before cleaning. The coated surface of the glass will be to the interior. Extra care must be taken whilst cleaning this surface to prevent damage to the coating. Ensure gloves are worn, and jewellery and watches are removed before cleaning.

  • Flood the glass surface generously with recommended cleaning product (clear liquid Windex (or similar), or a mixture of one part vinegar with ten parts water), or cloth saturated with the cleaning solution.
  • Wipe the wetted surface with a clean, lint free towel or cloth.
  • Wipe dry with a dry, clean, lint free towel or cloth. Do not use a squeegee on the coated (interior) surface.
  • To prevent streaking, stop wiping when the glass is almost dry and there is a uniform film of moisture left on the glass surface. The moisture will quickly evaporate leaving a clean surface.
  • Occasionally spot cleaning may be required to remove stubborn dirt or foreign materials that can adhere to the Low E glass surface. Spot cleaning products work to remove markings from grease, oil, tape adhesive and crayons, or other waxy materials as well as paint and rub-off marks from plastics. Apply a small quantity of the manufacturer’s approved cleaner for the type of coated glass you are cleaning, to a clean wet cloth or towel. Rub on areas of glass needing spot cleaning. Wipe clean using a dry, clean, lint free towel or cloth following the routine cleaning procedure given above. Do not use razor blades, steel wool, scouring bristles or other metallic or abrasive objects on the coated surface. If metallic objects touch the coated surface, a thin layer of metal removed from the object may be deposited onto the surface, which results in a discoloured stain that is difficult to remove using normal cleaning procedures.
How long will it take to complete my project?

It is hard to tell how long your glass project will take. Since we specialise in custom glass solutions, every project is assessed individually as no two jobs are the same. As a generally rule, toughened glass takes longer than standard glass as it needs more processing. Standard non-processed glass can be turned around faster, however it depends on various factors like complexity of the work, size of glass required, external or internal (external work may sometimes be delayed due to wet weather or windy conditions…), location and access of the project, availability of materials from suppliers.

You can rest assured we will keep you informed and up to date through the whole process.

What is Float glass?

Annealed or Float Glass is the basic flat glass product that is the first result of the float process. The float glass process is renowned for flatness and optical clarity. It is available as clear, tinted, high performance tinted, ultra-clear low iron glass and Low E pyrolytic coated glass. It is used in some end products — often in double-glazed windows, for example. It is also the starting material that is turned into more advanced products through further processing such as laminating, toughening, coating, etc. Annealed float glass is NOT a safety glass and when broken it tends to break into large, sharp, jagged shards.

What is Toughened Glass?

Toughened Glass (or tempered glass) is treated to be far stronger and more resistant to breakage than simple annealed glass, and to break in a more predictable way when it does break, thus providing a major safety advantage when compared to annealed glass in almost all of its applications.

Toughened glass is made from annealed glass treated with a thermal tempering process. A sheet of annealed glass is heated above its “annealing point” of 600°C; its surfaces are then rapidly cooled. The different cooling rates between the surface and the inside of the glass produces different physical properties, resulting in compressive stresses in the surface balanced by tensile stresses in the body of the glass. These counteracting stresses give toughened glass its increased mechanical resistance to breakage, and when it does break, causes it to produce regular, small fragments. Toughened glass also has an increased resistance to breakage as a result of stresses caused by different temperatures within a pane.

Toughened glass has extremely broad application in products both for buildings and for automobiles and transport, as well as other areas. Car side and rear windows, glass portions of building façades, glass sliding doors, partitions in houses and offices, glass furniture such as table tops, and many other products typically use toughened glass. Products made from toughened glass often also incorporate other technologies, especially in the building and automotive and transport sectors. Toughened glass cannot be cut after it has been toughened.

How do you clean standard, uncoated glass?

To clean standard, uncoated glass, remove any dirt or debris from the glass as soon as it is visible. When possible avoid cleaning glass in direct sunlight.

  • Flood the surface with water or cleaning solutions to remove loose dust and grit.
  • For best results, clean the glass beginning at the top and working downwards.
  • Wipe with a clean wet cloth, free of grit, (as gritty dirt particles picked up by the cloth could scratch the glass), until glass is visibly clean.
  • Rinse with clean water.
  • Dry immediately with a clean lint-free cloth or good clean squeegee.
  • Do not allow metal squeegee holders to touch the glass surface.
  • Do not use any additives that contain hydrofluoric acid, or have the possibility of forming hydrofluoric acid. Hydrofluoric acid is a highly corrosive liquid and is a contact poison.
How do you clean Mirrors?

Special care must be taken when cleaning mirrors particularly to the back and edges. Avoid any moisture or chemicals coming into contact with the silvering (back and edges) of the mirror.

  • Wipe over the surface with a few drops of methylated spirits on a damp cloth.
  • Polish surface dry with a lint free cloth.
  • Do everything possible to ensure that the cleaning cloths used are free of any abrasives.
How much will it cost to complete my project?

Since we specialise in custom glass solutions, every project is assessed individually as no two jobs are the same. Depending on the size and complexity of your project, we may be able to give you an estimate over the phone or by email, however for more complex glass projects, an onsite job assessment and measure may be required in order to provide you with a more accurate quote.

Once we have determined the cost of your job, you will receive a written quote. As a general rule, we require a 50% deposit paid by EFT for all jobs before we can put it into production. Once job has been completed, the remaining balance payable will be required.

You can rest assured we will keep you informed and up to date through the whole process.
