How the thermal break supports insulation
Aluminum conducts heat, so a continuous metal frame can provide a path between indoor and outdoor conditions. A thermal break interrupts that path within the profile assembly. This can improve frame insulation, but the performance of the installed window also depends on glass, spacers, seals, fabrication and the connection to the building.
For buyers seeking energy efficient aluminum windows, the useful question is how the complete assembly performs in the intended application. Ask for the relevant system evidence and compare like-for-like configurations. A material description or series number alone does not establish a whole-window U-value, a reduction in energy bills or an acoustic rating.
6063-T5 aluminum and matched system components
Selected MT Flying 55 and 70 outward-opening catalogue configurations list 6063-T5 aluminum, PA66 thermal insulation strips and EPDM seals. The published comparison lists 1.8 mm profile walls for both, with frame widths of 55 mm and 70 mm. These are specific catalogue references, and the approved section drawings should define the exact material ordered.
For a profile purchase, identify frames, sashes, mullions, glazing beads and all matching pieces. State whether thermally assembled sections, separate components or finished windows are required. A complete material list reduces the risk of receiving the main extrusion without the components needed to fabricate the intended window.
Glass options and the complete window specification
The selected 55 and 70 catalogue pages list a 5+15A+5 insulating-glass build-up. That notation describes two 5 mm panes around a 15 mm cavity. It is an assembly reference, not confirmation that glass is included with a profile order. Confirm the glazing scope, compatible beads and gaskets in the quotation.
Different projects may call for coated glass, laminated safety glass, other insulating units or specific appearance requirements. Send the proposed build-up and project criteria for a compatibility review. Glass selection should consider solar exposure, safety, light transmission and the intended thermal target alongside the frame. Request evidence applicable to the final configuration when a performance value is required.
Weather resistance starts with the details
A weather-resistant window needs matched seals, effective drainage, suitable hardware and a sound installation interface. Discuss opening direction and exposure with the technical team, particularly for upper floors, exposed facades or coastal locations. The selected 55 and 70 system references include drainage and sealing details that should be checked against the approved assembly.
Specify the required air, water and wind performance with the enquiry. Those requirements should be evaluated using documentation for the relevant configuration and dimensions. Site fixing, perimeter sealing and drainage outlets also matter after delivery. Avoid covering or blocking designed drainage paths when coordinating external finishes and internal reveals.
Applications in villas and apartments
Villa projects often combine fixed glazing with operable windows and large terrace doors. Review finish consistency, visible frame dimensions and the relationship between windows and adjacent sliding systems. An opening schedule lets the design team compare those decisions across the whole property rather than selecting each unit in isolation.
Apartment projects add repeated types, different floor exposures and installation sequencing. Group windows by type and clearly label variations in dimensions, glazing or hardware. That makes the material scope easier to price and supports checking quantities during packing and delivery. Confirm which items are finished units and which are profiles for local fabrication.
Commercial buildings and coordinated procurement
For offices, hospitality and other commercial applications, the consultant’s specification should lead the selection. Send drawings, performance requirements and any required submittal documents with the initial enquiry. The technical review can then focus on the relevant window family, glazing arrangement, hardware and building interface.
MT Flying’s profile production and window-and-door supply knowledge support a coordinated discussion of these items. Buyers can request a drawing review, sample discussion and itemized quotation before production. Confirm the approved revision and acceptance process so the factory, fabricator and site team work from the same information.
Finishes, export packing and quotation inputs
Powder coating, anodizing and other available finishes should be chosen for the appearance and service environment. Provide a color reference and identify whether the interior and exterior finish requirements differ. Agree the applicable finish sample and inspection criteria for the order.
For quotation, send opening dimensions, quantities, opening direction, glass build-up, hardware preference, finish and delivery destination. Include the requested tests or documents and identify installation responsibilities. MT Flying can then discuss profile supply, matching components or finished windows with packing arrangements suited to the actual shipment.
Factory support for your order
MT Flying connects aluminum profile production with window and door system knowledge. Our team can review the section, finish, related components and requested processing as one supply plan.
Confirm the approved drawings, material list, inspection requirements, packing and shipment arrangements before releasing production.
Frequently asked questions
Do thermal break profiles guarantee a specific window U-value?
No. Whole-window performance depends on the complete assembly, including glazing and dimensions. Request evidence for the proposed configuration and check it against the project specification.
What is the difference between the 55 and 70 series?
The selected outward-opening catalogue references list 55 mm and 70 mm frame widths. Both list 1.8 mm profile walls and 6063-T5 aluminum. Compare the actual section and installation details; a wider frame alone does not establish a higher performance rating.
Can you quote windows for a complete building?
Yes, share an opening schedule, drawings and performance requirements for review. Identify the quantities, glazing, finish, hardware and whether you need profiles or completed windows so the quotation matches your procurement plan.
