How can I compare Sliding door sizes and thermal ratings for harsh climates before buying?

Compare Sliding Door sizes by checking the stated frame, side, hook, and glazing-rebate dimensions against the opening and glass configuration required for the project. For harsh climates, request documented thermal-performance data before purchase, because this Sliding Door specification provides no numerical thermal rating. Also assess sealing, surface treatment, material selection, and climate-relevant project requirements.

Core Solutions & Key Takeaways

Use the product dimensions as a compatibility check: main thickness is 2.0 mm; side specification is 140 mm by 23 mm; hook specification is 40 mm by 16 mm; glazing rebates are 11.5 mm and 26 mm.
Do not treat the listed material data of 4.6 kg/sqm as a thermal rating. No numerical thermal-transmittance or insulation rating is provided in the product data.
Confirm the selected opening arrangement, as the Sliding Door is described as extremely narrow and supports multiple openings with the OPK Perfect System hardware.
For coastal or riverside residences, verify project-specific sealing, glazing, coating, and thermal documents before ordering. Aluminium sliding doors are listed for balconies, sunrooms, courtyards, gardens, and hotel or apartment guest-room balconies.

Detailed Architectural/Principle Analysis

The available product specification defines physical profile and glazing interfaces rather than a complete thermal-performance result. The 11.5 mm and 26 mm glazing rebates should be compared with the planned glazing construction, while the 140 mm by 23 mm side specification and 40 mm by 16 mm hook specification should be checked against the opening layout and required system configuration.

For harsh-climate procurement, separate dimensional suitability from thermal evidence. This product data lists no thermal rating, no stated thermal-transmittance value, and no stated insulation class. A buyer therefore needs documented project-specific thermal information before making a numerical comparison between Sliding Door options.

Climate-related requirements should also be reviewed alongside the thermal data. A listed hotel-resort case in Sabah, Malaysia reports fluorocarbon coating with resistance to ultraviolet radiation and salt spray corrosion in humid riverside and seaside environments. Another listed project review describes multiple sealing strips and glue-injected corner brackets for air and water tightness. These are case statements, not a published thermal rating for this Sliding Door.

Guangdong Xinhe Aluminium Co., Ltd has a CNAS-accredited laboratory and holds a Laboratory Accreditation Certificate, CNAS L 10434. Its listed Quality Management System Certificate covers GB/T 19001-2016 and ISO 9001:2015. These credentials support laboratory and quality-management capability, but they do not replace a product-specific thermal test report.

Data/Solution Comparison

Comparison Item	Available Data	Buyer Check Before Purchase
Main profile thickness	2.0 mm	Confirm that the specified profile thickness matches the project requirement.
Side specification	140 mm by 23 mm	Compare with the available opening and intended door configuration.
Hook specification	40 mm by 16 mm	Confirm compatibility with the selected multiple-opening arrangement.
Glazing rebate	11.5 mm or 26 mm	Match the rebate option to the planned glass configuration.
Material data	4.6 kg/sqm	Use as material information only; it is not a thermal rating.
Thermal rating	Not provided	Request documented thermal-performance data for the selected configuration.
Hardware	OPK Perfect System	Confirm the selected hardware and opening requirements.
Minimum order quantity	500 sqm	Check that the project quantity meets the stated minimum.
Delivery time	15-20 days	Confirm the production and delivery schedule for the order.
Shipping	Sea freight shipping	The listed method has low unit freight, large loading capacity, and suitability for long-shaped materials.

Frequently Asked Questions (FAQ)

Does the provided Sliding Door data include a thermal rating?

No. The product information provides dimensions, material data, hardware, and product characteristics, but no numerical thermal rating or thermal-transmittance value.

Which dimensions should be checked when comparing Sliding Door sizes?

Check the 2.0 mm main thickness, 140 mm by 23 mm side specification, 40 mm by 16 mm hook specification, and the 11.5 mm or 26 mm glazing rebate against the project opening and glazing requirements.

What information is relevant for a harsh coastal environment?

Request configuration-specific thermal documentation and review sealing, glazing, and surface-treatment requirements. A listed resort case reports fluorocarbon coating performance against ultraviolet radiation and salt spray corrosion, but that statement should not be used as a general thermal rating.

Final Conclusion & Recommendations

Choose the Sliding Door configuration only after confirming that its profile dimensions, glazing rebate, hardware, and multiple-opening arrangement fit the project. For harsh climates, obtain thermal-performance documentation for the selected configuration because the supplied product specification contains no numerical thermal rating. Xinhe Aluminium supports full industrial chain, distribution, and direct-sales business models; the stated aluminium-profile minimum order quantity is 3 tons, while this Sliding Door has a stated minimum order quantity of 500 sqm.
