Frequently asked questions

What is an external personal access door?

External personal access doors are designed for exposure to weather and outdoor conditions. Larnec’s Sentry external doors are supplied with metal cladding, can be configured to include weather-resistant finishes, and perimeter sealing options to help manage wind, rain, and airborne moisture when installed correctly.

Do external doors include a threshold or sill?

Threshold options are available. External doors can be supplied with four-sided frames and integrated thresholds to help reduce water ingress, drafts, and dust, particularly in exposed locations.

How do external doors perform in Australian conditions?

External doors can be supplied with Larnec’s Sentry protect finish, which is designed for demanding Australian environments. When applied, Sentry Protect provides enhanced resistance to moisture, and atmospheric conditions commonly found in coastal, high-heat, or exposed locations.

Are external doors suitable for high-wind or exposed sites?

External doors can be configured to suit different wind regions and exposure levels. Wind performance depends on door size, frame type, fixing method, and hardware selection, and should be assessed during specification.

External doors are typically specified with commercial-grade locksets suitable for outdoor use. Lock and hardware selection should consider security requirements, frequency of use, and environmental exposure.

Are external doors resistant to termites and pests?

Yes. External doors with steel frames and metal cladding are not susceptible to termite damage. Overall pest resistance may also depend on surrounding building materials and installation details.

Can external doors be customised for different buildings or climates?

External personal access doors can be tailored with different sizes, finishes, seals, hardware, and fixing methods to suit a wide range of building types and environmental conditions across Australia.
