Estimates

What information do you require to provide an estimate?

In order for us to give you the most accurate quote possible and pass your estimate to the correct department, we will need confirmation of whether the enquiry is either on a supply only or supply and fit basis.  Delivery addresses for both supply only and supply and fit are required before estimating.  Please supply glass specification(s) including, dimensions, colour and finish and please supply relevant drawings in CAD, DXF, DWG or PDF format.

Estimates are based on initial information supplied therefore costs may vary/change on final agreed details or after site survey. Delays in finalising prices may occur if either site access or outstanding information is unavailable when requested.

What does E&OE mean on my estimate?

E&OE means ‘errors and omissions excepted’.  In relation to a Gx Glass estimate and/or order,  this is where information supplied is, to the best of our knowledge correct, but we will not be held responsible if an error is found, therefore it is down to you, the customer, to ensure that all information supplied is correct on the estimate or at point of order.

What is the energy surcharge?

The Energy Surcharge (ESC) is a variable rate introduced by the European glass manufacturers to reflect the increase in the energy costs associated with the manufacture and distribution of glass, and applies to all glass sold since November 2004.

The amount is charged per kilo weight of glass supplied and is set once a quarter based on the IPE Brent Crude Oil Price Index in London.  The energy surcharge will now also include a currency exchange rate factor in the November 2008 and subsequent calculations.  Gx Glass cannot control this value which increases as well as decreases.

Surveys

What details are required for a survey?

Surveys (and installations) are managed through our installation manager; surveys normally require 5 days notice to attend site once Gx Glass have received your official purchase order / written confirmation to proceed.  

Please confirm site and personnel contact details as Gx Glass strongly recommend that a site representative is present at the time of survey to answer any question or agree / make decisions where required. Should there be no one on site qualified to instruct us Gx Glass may not be able to obtain the information required; this may result in a subsequent site visit and additional costs.

Our surveyors will have un-priced estimates and copies of the drawings used for the estimate. Please confirm they are the current version to be worked on.

Back To Top

What happens if I need to change my survey or installation dates?

If for any reason a proposed survey or fitting date needs to be changed it must be confirmed in writing, either by email or fax and sent to the installation department. Please request confirmation that we have received your revised instructions. Gx Glass requires a minimum 24 hours notice to cancel a survey and 48 hours to cancel an installation. If insufficient notice is given additional fees may be charged.

Gx Glass reserves the right to change a survey or installation date at any time, subject to a 24hr notice period due to glass breakage, delay in receipt of a deposit or delay in receipt of  3rd party fittings.

Back To Top

How do I place an order for supply and fit?        

Your official purchase order or written instructions to proceed should include the agreed estimate details and number. If there are any variances you must advise  us immediately. Gx Glass will then book in a suitable date for your survey.

Manufacturing and Processing

What does subject to manufacturing tolerances mean?

All glass when processed has a manufacturing tolerance – whereby during the cutting and machining of the glass, we guarantee the sizes to within a specified tolerance for that product.  Please see these below: 

  • 4- 6mm glass has a manufacturing tolerance of +/- 1mm
  • 8- 10mm glass has a manufacturing tolerance of +/-2mm
  • 12-15 glass has a manufacturing tolerance of +/- 3mm
  • 19mm glass has a manufacturing tolerance of +/- 4mm

Back To Top

Does your toughened glass adhere to British and European standards?      

Yes, we are compliant with BS EN 12150 and safety up to BS EN 12600 Class 1. 

Back To Top

What types of template do you accept for supply only goods?

Gx Glass accept rigid templates only (MDF, wood, corex or card), we unfortunately cannot accept paper templates as we are unable to scan them.  Please ensure any supplied templates have your estimate / order number and contact details clearly marked.

Back To Top

Are you able to bevel circles?

We are currently unable to offer shaped or circular bevels at this time.

Back To Top

What is a dubbed corner?

A dubbed corner is where the sharp point is removed from the corner of a piece of glass. This makes the corner safer and is used predominantly for table tops and shower screens. 

Back To Top

What does PAR stand for?

PAR means 'Polished all Round', where the glass is machine finished with a polished edge. If you do not require a polished edge, please specify this at time of order.

Back To Top

What does clean cut mean?

Clean cut glass is cut and supplied without any edge finishing.  Should you require the sharpness to be taken off of your glass, you can request an arrised edge, which is a hand finish.

Back To Top

What adhesive should I use to fix my glass?

Gx Glass can supply suitable adhesives depending on which product you have purchased, please ask when requesting a quotation. Gx Glass will not be responsible for any damage caused if incorrect fixing adhesive is used.

Back To Top

Fitting

What does ‘fitting to prepared surfaces' mean?

Gx Glass only fit to prepared surfaces.  The surface to which the glass is to be adhesive fixed to must be sealed, flat and smooth; we cannot fix glass to bare plaster.

All surfaces can be sealed using a diluted solution of a PVA such as ‘Unibond’ or standard emulsion, this is also relevant to substrates such as melamine.

All sockets and other electrical or multimedia fittings must be disconnected and made safe by a qualified person, socket cover plates are to be removed by you or your contractor and wiring made safe whilst Gx Glass install the glass, they can be refitted carefully after the glass is installed.

Back To Top

Does your fitting include fixing of sinks or hobs?

 

The fitting of hobs, sinks or any other appliances are not included in our fitting costs. For one off domestic installations Gx Glass include silicone pointing along the bottom edge of the glass unless otherwise stated in our estimate. For contract installations Gx Glass do not include silicone pointing unless it is explicitly specified and priced at the initial enquiry.  All silicone pointing is subject to on-site conditions. Gx Glass do not include the supply or installation of fittings unless agreed at the time of the initial enquiry. A signature from the client will be required on completion. Once Gx Glass have left the site Gx Glass will not accept responsibility for any loss, damage or movement to the panels Gx Glass  have fitted.

Back To Top

What are your fitting tolerances for splashbacks?

Typical 6mm Glass Splashback and wall cladding:

All panels are surveyed and templated to allow a nominal 2mm gap between external edges of a panel and adjoining item. (See image A below) Gx Glass can accommodate out of square panels, however Gx Glass do not measure glass to follow irregular wall finishes other than in straight lines.   If two glass panels are required to butt together there will be no gap except in shower and bath installations which will have a 4mm gap for a silicone beading joint.  

All splashbacks and wall cladding panels will be installed 2mm off of the worktop or up-stand using clear plastic setting blocks; these will be cut back prior to  silicone pointing. Every effort will be made to ensure that the setting blocks are not seen, but we cannot guarantee this unless they are removed; this can only take place 36 hours after installation once the adhesive has cured, and will require a return visit  to carry out the silicone pointing. If you require us to remove the setting blocks,  please make this known as soon as possible, as if we have to return to site there may be additional charges made. This only relates to domestic installations.

Socket Cut Outs and Holes

Cut outs need to be a minimum of 50mm from the edge of the cut out to the edge of the glass, with a further 50mm between cut outs (in-fill pieces can be used for double sockets if required).  Socket cut outs are priced for a cover plate to sit over the face of the glass; if for any reason an item has to sit inside the cut out (within the glass) this needs to be made clear at the initial enquiry stage.

Gx Glass reserves the right to decline to a produce a panel should we feel that the size or quantity of cut outs will be detrimental to the safe handling or installation of the glass (see image B below). If fittings are to be installed on to the face of the glass e.g. extractors, we will drill the glass to accommodate a suitable sized nylon bush to avoid the weight of the fitting being carried by the glass.

Holes drilled in toughened panels will be be of an equal diameter to the thickness of glass or greater. e.g. 6mm toughened glass will have a minimum 6mm diameter hole drilled.

If you require a panel that has different height levels along its length (see image C & D below) this can now subject to manufacturing and product tolerance be produced in one section. Please note that in 6mm glass the internal corners will have a minimum radius of 8mm and that the edges of the cut out section will have a water jet (ground) edge finish and will not polished, should any part of these edges be visible, then please let us know in your initial enquiry and we will allow for hand or CNC polishing.

What are your fitting tolerances for worktops?

Typical 19mm Toughened Glass Worktop and Vanity Tops:

Please note that all glass can scratch, mark and chip and this is especially relevant for worktops, vanity tops and breakfast bars. Please ensure that you and your end client are aware of these potential challenges as Gx Glass will accept no responsibility for any issues that arise from a customer not being aware of this. We recommend that only toughened glass is used as either a worktop, vanity top or breakfast bar

If you wish to use any product apart from toughened glass, contact the office first for technical advice.

Toughened glass will have an edge mark logo; unless you specify which edge you want it on we will apply it where the operator deems appropriate.

Flush Fitting Work or Vanity Tops

Whilst every effort would be made to achieve a flush finish, due to manufacturing tolerances we cannot guarantee that it will be accurate enough. We would advise having a small overhang, and any order placed will be on this basis.

Fitting of Hobs and Sinks into Worktops

Please note that not all hobs will fit into a glass worktop; to manufacture a 19mm toughened top with a cut out we have to have a minimum of 20mm internal radius corners in the cut out, this may not be compatible with your hob. This is also relevant to a certain extent with sinks. It is your responsibility to ensure that your proposed hob or sink can accommodate these radius corners.  Should the cut out need to have a polished finish, then the  internal corner will have a minimum radius of 25mm. Note that once a panel has been toughened, we are unable to carry out any further edgework or drilling. On square or rectangular panels the polished edge on an internal cut out will not match the polished edge on the external edges of the panel as two processes are involved.

If you require a hob or sink, there are a number of manufacturing tolerances to take into account, please see image E below for more detail. If you require a work or vanity top that has an under mounted sink, again please note because of the 20mm radius corner in the glass, the glass top may not line up with the sink below, especially at the corners. We would normally fit the glass so that the edges of the cut out in the glass sit slightly back from the sides of the sink.  This detail stops water getting between the vinyl backing and the paint; in addition it protects the otherwise exposed glass edge when either loading or unloading the sink.

How do I calculate the weight of glass?

To calculate the weight of glass you multiply the area by the thickness and the multiply that by 2.5 (a fixed weight for glass). 

For Example - to find the weight of .75m2 of 6mm silver mirror

0.75 x 6 x 2.5 = 11.25kg

Delivery

Why is your delivery date ‘estimated’?

Please note that glass is a fragile product, and due to this our lead times are based around the optimum production time for the glass to be processed, allowing for contingency should the glass break during this time.  We endeavour to provide accurate lead times, but these are always estimated as, for example, should a machine suffer from mechanical failure, the stated lead time will no longer be correct.  Therefore if you require a definitive lead time for a job, please ensure that we are aware of this. 

Back To Top

What are the terms of your Delivery service?

All supply only deliveries are on a loose load tailboard only basis unless otherwise agreed during estimating. Should you require your goods to be delivered on a stillage or crated then it is dow to you, the customer, to arrange suitable labour and equipment to unload the glass. 

We can only offer AM or PM delivery slots, but should you require a timed delivery, we can offer the first delivery of the day between 8am-9am. 

Any challenges to being able to access a site or provide the goods to the correct person may require additional charges if it results in rescheduling of the delivery. All goods must be checked and signed for on delivery.  Out of hours deliveries or installation work must be agreed at the estimate stage.

Supply only estimates are on an ex-works (collection) basis unless otherwise agreed in advance. Please check the estimate carefully upon receipt.
