Door Astragal

Key Functions of Door Astragals

The following are the main functions of door astragals:

• Gap Sealing: Astragals cover the space between double doors, effectively sealing the gap to prevent the entry of light, sound, and drafts. This function is particularly important for exterior doors or in areas requiring climate control.
• Better Insulation: They help to maintain consistent interior temperatures and energy efficiency by bridging the space between door leaves.
• Soundproofing: They minimize noise transfer through the door gap, making them useful in environments where noise control is crucial.
• Draft Prevention: They help block drafts and air leaks, enhancing comfort and reducing heating or cooling costs by maintaining better control over indoor climates.
• Smoke and Fire Protection: They play a crucial role in preventing the spread of smoke and fire between rooms during emergencies, especially with fire-rated doors. 
• Increased Security: Astragals provide an extra layer of protection by bridging the space between doors, making it more difficult for burglars to force them open.
• Clean Aesthetics: These door components provide a clean, finished look to double doors, enhancing the overall appearance of the door installation.
