aïr performance standards explained

we have quite simply thought of everything

When it comes to looking for a set of sliding or bi-fold doors, many people don't know what to look out for. What separates the average from the best? It is hard to distinguish. We want to make that easy for you, and so we hang our hat on the following measures. Whether you are buying a set of aïr doors or not - always demand to know what you are putting into your home.

  • Security

    Our homes are precious, they hold inside the things most dear to us. Don't compromise security. aïr doors are tested to PAS 24 standard - keeping even the most determined of intruders out.

  • Weather Performance (pa)

    The elements naturally play a huge role in testing the integrity of your doors. Thats why wind load and watertightness are essential values to be aware of. Wind load is the amount of force a structure can take from the impact of the wind. Watertightness is the measure of how much water can penetrate an object. Both are measured in pascals (pa). The higher the pa value the better.

  • U Value (W/m2k)

    A U value is a measure of heat loss. It is expressed in W/m2k, and shows the amount of heat lost in watts (W) per square metre of glass. The lower the U value, the better the insulation provided by the material.

  • 25 year guarantee

    Investing in a set of high-end doors is probably a once in a lifetime decision. aïr is the most impressive range of high performance doors. We are so confident of this, we have an industry leading 25 year manufacturer guarantee on all aïr doors.

  • aïrcoat colour protection

    The level of protection or determination of paint can be related to the value of thickness of the paint that is applied to a door. This value is referred to a microns. The higher the micron value is one indication of the life that the paint will give you.
