A GUIDE TO THE SPECIFICATION OF SEALS

For doors or windows to function, they must have gaps between their edges and the frame. These gaps are there to allow easy opening and closing and to accommodate normal building movement. However, these gaps can also allow the intrusion of:

• sound, fire and smoke, rain, cold draughts, dust and embers, light, insects and vermin, and also the leakage of energy, heating and air conditioning.

Specification

You may find that a door will be required to fulfill several functions at once, such as security, fire and weather control. If this is the case, you will need to consider seals, which will achieve the desired objectives but do not interfere with other door hardware.

When choosing your Raven seal, you should consider:

• does it provide the required protection?
• does it provide that protection without impeding the normal use of the door?
• Is it compatible with the construction of the door and other hardware?
• is it suitable for the projected level of use

Suitability, is it suitable for the door configuration?

• single leaf, butt hinged inward or outward opening

• two leaves, butt hinged inward or outward opening
• one only active leaf
• rebated or plain meeting stiles
• revolving, sliding, bi-fold or pivot hung
• single or double
• wood, metal, glazed.

The situation, is it intended for external, internal, residential, commercial fire door and so on? Each Raven item has been assigned a level indicating its suitability for the severity of the installation:

H (Heavy Duty)

M (Medium Duty)

L (Light Duty)

Adjustability

Many Raven seals have some degree of adjustability and can be adjusted without removing the door or window. Thus maximum efficiency can be maintained in the event of minor building or door movement.
