Q
Are your wood-aluminum windows energy-efficient?
Absolutely. Our 90mm frame system features multi-cavity designs and triple-glazed Low-E glass, achieving an ultra-low U-value of 1.1-1.2, fully meeting international passive house energy-saving standards.
Q
What kinds of wood options do you offer?
We offer premium, seasoned solid woods including imported Oak, Larch, and Pine. All timber undergoes rigid moisture control treatment to ensure zero warping or cracking over decades.
Q
Can you provide technical or engineering support for my project?
Yes, we provide full engineering support. Our design team can analyze your architectural plans to offer free CAD shop drawings, 3D model configurations, and structural wind-load advice.
Q
What brand of hardware do you use for your premium windows?
We use top European brands such as Germany ROTO and SIEGENIA to ensure heavy-duty security, smooth operation, and long-lasting durability.
Q
Do your wood-aluminum windows meet North American building codes and NFRC/AAMA requirements?
Yes. Our premium windows are engineered to align with North American structural and thermal efficiency standards. We can provide technical parameters, structural wind-load analysis, and certification documentation required by local US/Canadian building departments for permit approvals.
Q
What glass options do you provide for North American climate zones (e.g., California Title 24 or Canada Zone 3)?
We provide high-performance insulated glass units (IGUs) with double or triple-pane Low-E coatings (such as Cardinal Low-E 270/366), Argon gas fills, and warm-edge spacers to ensure compliance with local energy codes.
