For international door and window projects, product appearance and price are only part of the purchasing decision.
Different markets may have different requirements for energy efficiency, structural performance, air leakage, water resistance and product compliance.
For developers, contractors and importers, identifying the applicable standards early can help avoid specification problems later in the project.
NFRC ratings are commonly used in the United States to provide standardized information about the energy performance of windows, doors and skylights.
Depending on the product, buyers may encounter performance values such as:
U-Factor — Heat transfer through the product
SHGC — Solar heat gain through the product
VT — Visible light transmission
For U.S. projects, buyers should confirm whether the specific product and configuration require relevant NFRC ratings.
NAFS is an important performance standard for windows, doors and skylights in North America.
Testing can address areas such as:
Air Leakage + Water Penetration + Structural Performance
The required performance level can vary depending on building location, product size, installation conditions and project specifications.
This is especially important for high-rise, coastal or other exposed projects.
Canadian projects may involve CSA standards and requirements referenced by applicable building codes.
Cold climates also make thermal performance, glazing configuration and air tightness important considerations when selecting windows and doors.
Project buyers should confirm the exact requirements for the province and project before ordering.
AS 2047 is an important standard for windows and external glazed doors used in buildings in Australia.
Performance considerations can include:
Operating force
Air infiltration
Water penetration resistance
Ultimate strength
Deflection
Requirements can vary according to building design and project conditions.
For Australian projects, product selection should therefore consider both the required standard and the actual application.
For European projects, applicable product standards and regulatory requirements should be confirmed according to the destination market and intended use.
Performance characteristics may include areas such as:
Thermal Performance · Air Permeability · Watertightness · Resistance to Wind Load
Because requirements can differ between products and projects, buyers should confirm the applicable specification rather than simply asking whether a window or door is “European standard.”
One important point for B2B buyers is that a certification should not be evaluated only by seeing a logo.
Ask the supplier to confirm:
Product Series → Size → Glass → Configuration → Tested Performance → Applicable Standard
Changing the dimensions, glass, hardware or configuration may affect whether test results apply to the product being ordered.
Project Tip: Send the destination country, architectural drawings and required performance specifications to the supplier before finalizing the window and door system.
There is no single certification that applies to every global project.
USA → NFRC / NAFS
Canada → CSA / NAFS-related requirements
Australia → AS2047
Europe → Applicable CE / European requirements
The exact requirements should always be confirmed according to the destination, building type and local project specifications.
Send JBDHOME your project location, drawings, dimensions, quantities and required standards.
