Build a Raven Specification

The Problem

For doors and windows to function, they must have gaps between their edges and the frame to allow for easy operation and to accommodate normal building movement.

However, these gaps can allow the intrusion of draughts, dust, insects, rain, noise, vermin, fire, smoke or bushfire embers. Unsealed doors and windows allows the leakage of heating and cooling which significantly increases energy costs and reduces the energy efficiency of other design elements of a building.

The Solution

The solution is to fit a Raven sealing system which seals the gaps around doors and windows against a combination of intrusions and leakages. Properly selected and installed, a complete and continuous seal can be achieved for all door and window types without impeding their normal use.

Optimum “sealing systems” can be achieved by combining the appropriate Raven door bottom seals, threshold plates, perimeter seals and meeting stile seals.

Product Selection

When choosing Raven sealing systems, you should consider:
  • What type of protection is required?
  • What type of door or window do you want to seal?
  • Does it provide protection without impeding normal door or window function?
  • Is it compatible with other door or window hardware?
  • What type of duty is required?
  • Is it for an external, internal, residential or a commercial situation?
  • What are the building code requirements?

Duty Levels
Icons have been used to assist specifiers and builders to select the right duty level to meet the expected duty cycle for each building class.

Light Duty
Generally used in residential and light traffic areas such as Class 1 – 4 Buildings.

Medium Duty
Generally used in commercial and medium traffic areas such as Class 3 – 6 Buildings.
    • Office spaces
    • Shops
    • Commercial accommodation

Heavy Duty
Generally used in heavy pedestrian and wheeled traffic areas such as Class 5 – 10 Buildings.
    • Public hospitals
    • Airports
    • Factories
    • Shopping centres


Icons have been used to help identify appropriate seals for various applications to make product selection easier. All seals are designed to meet most standards and in most cases, perform more than one function. Refer to standards and authorities.
