Curtain Wall Manufacturer China Foshan Factory Price Thermal Break Low-E Insulated Glass

1. System Overview — The Envelope Is the Façade

A curtain wall is the building’s outer skin hung from the structure, carrying the weather and the daylight, and the honest engineering question of a curtain wall is not the glass or the mullion, it is the heat, because a curtain wall is a layer of aluminum in front of a layer of glass, and aluminum conducts the heat of the outside straight through to the inside, and the glass passes the heat of the sun straight through to the room. What defines a curtain wall that works is the thermal break in the aluminum that stops the heat crossing the mullion, and the low-E insulated glazing that stops the heat crossing the glass, and the pressure-equalized cavity between the two that stops the water and the air. Richocean manufactures curtain walls in Foshan from 6063-T6 aluminum with a thermal break in every mullion and every transom, low-E insulated glazing, and a pressure-equalized cavity, set to the building’s thermal specification and the climate the building stands in.

Three questions decide whether a curtain wall works: whether the aluminum carries a thermal break that stops the heat crossing the mullion, whether the glazing carries a low-E coating and an insulated build that stops the heat crossing the glass, and whether the cavity between the two is pressure-equalized that stops the water and the air. The thermal break and the glazing are the thermal of the wall, and the pressure-equalized cavity is the weather of the wall, and the two together are the envelope the building stands behind.

2. The Thermal Break — Stopping the Heat at the Mullion

The mullion and the transom are the aluminum of the curtain wall, and the thermal break is what stops the heat crossing that aluminum, because aluminum without a break is a thermal bridge from the outside to the inside:

• Why the break: aluminum conducts the heat of the outside straight through the mullion to the inside, and the mullion is a thermal bridge, and the thermal bridge is the place the heat crosses and the place the inside of the mullion drops to the dew point, so the thermal break is the part of the mullion that stops the heat and holds the inside above the dew point
• PA66GF25: the thermal break is a PA66GF25 glass fiber nylon insert, and the insert is set between the outside and the inside of the mullion, and the PA66GF25 is the material that does not conduct the heat the aluminum conducts, so the break is the barrier the heat must cross and the barrier that stops the heat
• Break width: the width of the break is set to the building’s thermal specification, and the wider the break, the lower the heat the mullion carries, and the break width is the dimension the thermal performance of the mullion is set to
• Mullion and transom: every mullion and every transom carries the break, and the break is the thermal of the whole wall, and a wall that breaks some mullions and not all is a wall that carries the heat at the mullions it does not break
• Inside face: the inside face of the mullion is held above the dew point by the break, and the inside face is the place the condensation would form without the break, so the break is the condensation control of the mullion
• Spigots and joints: the mullion spigots and the joints carry the break through, and the break is continuous through the spigot, so the thermal bridge does not re-form at the joint where the mullions meet

The thermal break is what stops the heat crossing the mullion, because aluminum without a break is a thermal bridge from the outside to the inside, and the thermal bridge is the place the heat crosses and the place the inside of the mullion drops to the dew point. The break is a PA66GF25 glass fiber nylon insert set between the outside and the inside of the mullion, and the width of the break is set to the building’s thermal specification, and every mullion and every transom carries the break, so the break is the condensation control of the mullion and the thermal of the whole wall, and the break is continuous through the spigot so the thermal bridge does not re-form at the joint.

3. Low-E Insulated Glazing — Stopping the Heat at the Glass

• The sun and the room: the glass of the curtain wall passes the heat of the sun straight through to the room, and the room passes the heat of the inside straight out through the glass, and the glass without a coating is the thermal bridge the mullion is, so the glazing is set to stop the heat at the glass
• Low-E coating: the low-E coating is a thin metal oxide on a surface of the glass, and the coating reflects the long wave heat back where it came from, and the coating is set to the surface of the glass by the climate, so the heat of the room is reflected back to the room in the cold season and the heat of the sun is reflected out in the hot season
• Insulated build: the glazing is an insulated build, and the build is two or three panes of glass with a gas-filled cavity between, and the cavity is the barrier the heat must cross, and the gas in the cavity is the material that does not conduct the heat the air conducts, so the build is the thermal of the glazing
• Solar control: the solar control coating is the part of the glazing that stops the heat of the sun, and the coating is set to the solar specification of the project, and the coating is the element that stops the sun’s heat and passes the daylight, so the sun’s heat is stopped and the daylight passes
• U and the g: the insulated build is set to the U of the wall, and the coating is set to the g of the wall, and the U and the g are the two numbers the thermal performance of the glazing is set to, and the U is the heat the glass carries and the g is the heat of the sun the glass passes
• Safety: the glazing is classified to EN 12600, and the glass is laminated where the fall is a requirement, and the safety is the part of the glazing that the glass holds if it is struck, so the glazing is the safety of the wall

The low-E insulated glazing is what stops the heat at the glass, because the glass without a coating is the thermal bridge the mullion is, and the glass passes the heat of the sun straight through to the room and the heat of the room straight out through the glass. The low-E coating reflects the long wave heat back where it came from, and the insulated build is the barrier the heat must cross, and the solar control coating stops the heat of the sun and passes the daylight, so the U and the g are the two numbers the thermal performance of the glazing is set to, and the glazing is the safety of the wall.

4. The Pressure-Equalized Cavity — Stopping the Water and the Air

• The cavity: the curtain wall is set with a cavity between the outside and the glazing, and the cavity is the space the water and the air move in, and the cavity is the part of the wall that manages the weather
• Pressure equalization: the cavity is opened to the outside at the weeps and the vent, and the pressure in the cavity is equal to the pressure of the outside, and the equal pressure is the part of the wall that stops the water being driven through the glazing, because the water is driven by the difference of the pressure, and the difference is removed
• The weeps: the weeps are the openings at the bottom of the wall, and the water that enters the cavity leaves at the weeps, and the weeps are the drain of the wall, so the water is not stored in the cavity
• The gasket: the glazing is set on the gasket, and the gasket is the seal of the glazing, and the gasket is set to the movement of the glass, so the gasket holds the glass and the glass moves without the gasket failing
• The air: the air is stopped at the cavity, and the air that enters the cavity is equalized and leaves at the weeps, and the air is the part of the wall that the pressure-equalized cavity manages, so the air is not driven through the wall
• Testing: the wall is tested for the water and the air and the wind, and the test is the wall and not the mullion and the glazing apart, and the test is set to the project’s specification, so the wall is the wall the customer receives

The pressure-equalized cavity is what stops the water and the air, because the curtain wall is set with a cavity between the outside and the glazing, and the cavity is the space the water and the air move in. The cavity is opened to the outside at the weeps and the vent, and the pressure in the cavity is equal to the pressure of the outside, so the water is not driven through the glazing by the difference of the pressure, and the water that enters the cavity leaves at the weeps, and the air is stopped at the cavity and equalized, so the pressure-equalized cavity is the weather of the wall, and the wall is tested for the water and the air and the wind as one.

5. Condensation Control — The Dew Point Stays Outside the Wall

• Why condensation: the curtain wall is the cold surface of the building, and the inside air meets the inside face of the wall, and the inside face is the place the condensation forms, so the wall is set to hold the inside face above the dew point
• The break and the face: the thermal break holds the inside face of the mullion above the dew point, and the glazing build holds the inside pane of the glass above the dew point, and the two together are the condensation control of the wall
• Thermal specification: the wall is set to the building’s thermal specification, and the specification is the dew point of the climate, and the break and the glazing are set to the specification, so the wall is the wall that does not condense in the climate it stands in
• The frame and the glass: the frame and the glass are set to the same line, and the line is the inside face of the wall, and the line is held above the dew point, so the frame and the glass are the same wall and not two walls
• Verification: the condensation is verified to the specification, and the verification is the inside face of the mullion and the inside pane of the glass, so the condensation is the part of the wall that the specification is set to and the wall is verified to

The condensation control is the part of the wall that holds the dew point outside the wall, because the curtain wall is the cold surface of the building, and the inside air meets the inside face of the wall, and the inside face is the place the condensation forms. The thermal break holds the inside face of the mullion above the dew point, and the glazing build holds the inside pane of the glass above the dew point, and the two together are the condensation control of the wall, and the wall is set to the building’s thermal specification and verified to the specification, so the wall is the wall that does not condense in the climate it stands in.

• Mullion and break: every mullion and transom set with the break, and the break continuous through the spigot, so the thermal bridge does not re-form at the joint
• Glazing and gasket: the glazing set on the gasket, and the gasket set to the movement of the glass, so the gasket holds the glass and the glass moves without the gasket failing
• Cavity and weeps: the cavity set to the pressure-equalized line, and the weeps set at the bottom, so the water that enters the cavity leaves at the weeps
• Condensation check: the inside face of the mullion and the inside pane of the glass confirmed to the specification, so the condensation is held outside the wall
• Testing: the wall tested for the water and the air and the wind as one, and the test is the wall and not the mullion and the glazing apart
• Maintenance: periodic inspection of the glazing, the gasket and the weeps, with the cavity checked for the water and the wall checked for the condensation
