Custom Insulated Glass Units for Building Projects

EVERMADE GLASS supplies custom insulated glass units from China for building projects and trade buyers. Share your glazing schedule, unit construction, quantities and destination. We review the proposed glass supply and performance-document requirements before preparing a quotation.

For designers, contractors & glass businesses · Export supply from China

Specify the Complete Insulated Glass Unit

Insulated glass units (IGUs) use panes separated by a sealed cavity. Double-glazed units have two panes; triple-glazed units have three. Specify the assembly from outside to inside so the quote addresses the complete unit. Supply feasibility is reviewed for the proposed configuration.

Outer paneThickness, glass type and treatment
CoatingSpecified product and coated surface, if defined
CavityWidth and specified air or gas fill
Spacer and edge sealRequired system and material compatibility
Inner paneThickness, treatment and laminated build-up if used
Finished unitOverall thickness, dimensions, quantity and drawings
Performance scopeGlazing or whole-window targets and supporting documents

Low-E and Solar-Control Requirements

For a Low-E or solar-control specification, send the required coating or performance targets, including U-value, solar heat gain coefficient and visible light transmission where applicable. Include the reference method and whether the targets concern the glazing or the complete window system. These values need to be assessed for a defined construction. A coating name alone does not establish the performance of every unit. We confirm the proposed glass and available supporting documentation during quotation review.

Cavity, Spacer and Edge-Seal Details

The cavity, spacer and edge-seal specification are part of the unit, alongside the glass panes. Identify any required spacer system, air or gas fill, and sealant requirements. Where the unit will be used in structural glazing or another specialist assembly, include the relevant system details and compatibility requirements for review. Required materials and supply availability are confirmed for the order. We do not treat different spacers, fills or sealants as automatic substitutes for one another.

Glass Options and Fabrication Review

Include any clear, low-iron, tinted, tempered or laminated pane requirements in the glass schedule. If one pane is laminated, give the glass layers and interlayer specification as well as the overall IGU construction. Provide dimensioned drawings for shapes, offsets or other fabrication features, and identify the glazing system where available. Feasible sizes and fabrication details are reviewed together with the configuration and handling requirements. Send curved or otherwise complex units for a separate feasibility review.

Thermal, Acoustic and Safety Requirements Need the Full Build-Up

A project may ask one unit to address several requirements, such as solar control, noise reduction and safety glazing. Include each requirement in the enquiry and identify the documents needed for approval. The glass construction, cavity, edge system and final installation all matter to the assessment. Where acoustic performance is specified, request evidence for the relevant assembly rather than assuming double glazing is soundproof. Test reports or calculated values should identify the construction and the scope they cover.

Inspection, Packing and Project Delivery

Inspection records can be provided and third-party inspection can be coordinated for the proposed order. Share the inspection scope, approval documents and any identification or packing requirements before production is agreed. Tell us the destination, delivery programme and expected handling arrangements so packing and shipment can be discussed with the unit configuration. Production and transport timing are confirmed for the order. Do not assume a local replacement-glass delivery schedule applies to an export project.

Send Your IGU Schedule for a Supply Quotation

Provide the details below, marking any undecided items. For standard projects with the necessary information, a formal quotation is normally prepared within 1–3 working days; complex projects can require additional review. Our scope is architectural glass supply from China; your project team arranges installation.

  • Application and project destination
  • Outside-to-inside build-up, including coating and cavity
  • Dimensions, quantities and current drawing revision
  • Specified performance and required supporting documents
  • Requested delivery date and any packing or inspection requirements

Project questions

Are insulated glass units and double-glazed units the same?

Double-glazed units are one type of IGU. They have two panes separated by a sealed cavity. Triple-glazed units have three panes and two cavities. Use the full build-up to identify the required product.

Does Low-E describe a complete insulated unit?

No. Low-E describes a coating function, while an IGU is a complete assembly. The pane types, coating position, cavity and other components still need to be specified.

Can an IGU include laminated or tempered glass?

Include these pane requirements in your schedule. A laminated pane needs its own glass-layer and interlayer details, while tempered panes need to be identified in the overall construction.

Can you quote a required U-value or acoustic target?

Send the target, assessment method, complete construction if available, and required supporting documents. We review the proposed supply and documentation against those requirements before confirming the quotation.

Is this a local window-repair service?

Our focus is architectural project and trade supply from China, including glass for windows, facades and other building applications. We do not provide local installation or repair. A contractor or trade buyer can submit a replacement package with its specification, quantity and destination.

Do you have a minimum order or fixed delivery time?

Send the quantities, construction, destination and required date. Order suitability, production scheduling, packing and shipping terms are reviewed for the project rather than quoted as one universal limit.

Have a glass schedule or drawing?

Send the information you have. Include the glass type, approximate quantity and destination. We can clarify the remaining details with you.
