Before you specify
What does "thermally broken" mean?
A thermal break separates the interior and exterior metal portions of a frame to reduce heat transfer. Tuscan Secco is the thermally broken option in this comparison. Review the specific system and glazing performance with our team.
Can S40 be used outside?
S40 is designed primarily for interiors. Select exterior applications in modest climates may be suitable, depending on the opening and project requirements. Confirm suitability before specifying.
What are TDL and SDL?
TDL means true divided lite: separate glass panes divided by framing. SDL means simulated divided lite: applied bars create a divided look. S40 and Classic offer both; confirm details for your configuration.
What should I send to get a recommendation?
Share the project location, interior or exterior use, approximate opening dimensions, preferred operation, drawings or inspiration, and any thermal or impact requirements. We will help narrow the options and prepare a quote.
