Energy Saving Warm Edge Spacer
Energy‑saving warm edge spacer is hollow composite profile formed by cold‑hot co‑extrusion craft. It combines high‑insulation flame‑retardant polymer substrate and 304 stainless steel layer to build hollow cavity for desiccant filling. Unlike traditional full‑aluminum cold‑edge spacers with high heat transfer efficiency, this warm‑edge product interrupts metal heat conduction paths

Factory Strength
Energy‑saving warm edge spacer acts as core thermal‑break component for high‑performance insulating glass units
Brief Introduction
Hebei Xinjian Metal Products Co., Ltd is a large‑scale high‑tech manufacturer located in Renqiu, Hebei, occupying a plant area of 50,000 square meters. We operate ten dedicated warm‑edge production lines to manufacture three main categories: composite warm edge spacer, PP co‑extruded stainless‑steel warm edge spacer and fiberglass‑reinforced warm edge spacer. Our size portfolio covers 5.5A‑27A, covering most market demands for energy‑saving windows, curtain walls and passive building projects. Featuring low thermal conductivity λ=0.16W/(m·K), this spacer cuts thermal bridging at glass edges and effectively suppresses surface condensation. We deliver matching corner keys, molecular sieve, hot‑melt butyl sealant and two‑component silicone sealant to realize one‑stop sourcing. Test samples are available for customers to run practical performance evaluation
High‑grade flame‑retardant polymer granule and 304 stainless steel thin sheet serve as main raw inputs. We strictly carry out incoming material inspection before co‑extrusion procedure. Adopting mature cold‑hot co‑extrusion compounding process, we control temperature parameters precisely to avoid delamination between polymer and stainless‑steel layers. Precision punching creates evenly‑distributed vent holes to guarantee stable moisture exchange for inner molecular sieve. Different series adopt adjusted formula orientation: composite warm edge for general energy‑saving projects; PP co‑extruded stainless‑steel type focuses on flexible bending performance; fiberglass‑reinforced variant enhances structural rigidity for large‑size glazing. Every finished batch goes through dimension check, bending test and visual inspection before warehousing
Physically separate two glass panes and maintain fixed cavity thickness for insulating glass unit;
Inner hollow cavity accommodates 3A molecular sieve desiccant to absorb moisture and volatile organics trapped inside IGU cavity;
Suppress thermal‑bridge transmission on glass perimeter, lift glass‑edge surface temperature and reduce condensation risk in cold‑climate zones;
Cooperate with hot‑melt butyl primary‑seal and silicone secondary‑seal system to guarantee long‑term gas‑tightness and water‑tightness of double‑glazing;
Compensate pressure difference caused by diurnal and seasonal temperature variation, mitigate thermal‑stress damage risk and extend overall service life of insulating‑glass assemblies
Main Features
Ultra‑low thermal conductivity λ=0.16W/(m·K), reduce thermal loss on glass perimeter and improve anti‑condensation performance for cold‑climate regions
Polymer‑stainless‑steel hybrid construction balances structural rigidity and thermal‑insulating property; 10‑20‑year service life under qualified IGU processing
Stable bending performance, compatible with automatic bending equipment; reliable bonding performance with mainstream insulating‑glass sealants
Excellent weather‑resistance and UV‑aging resistance; no corrosive volatile precipitation, friendly for Low‑E coated glass
Possess flame‑retardant property, bring auxiliary noise‑reduction effect for double‑glazing systems
Multiple series and complete size range, matched corner‑key accessories are supplied together to simplify ordering procedure
Products are packed in heavy‑duty export cartons with inner moisture‑proof barrier layer, preventing scratch, dent and profile deformation during sea or land transportation. Goods are packed according to standard meterage of corresponding model. Standard in‑stock sizes can be delivered within normal lead‑time. Large‑volume project orders follow mutually‑confirmed production schedule. Shipment via customer‑nominated freight forwarder is supported. All quoted prices exclude freight cost and tax
We can provide packing list, commercial invoice, product performance datasheet and factory introduction document for customs clearance and international project tender
