Frequently asked questions


What is CBD Windows™?

The CBD Windows™ range includes a full range of windows, doors, bi-folds, and sliders; in fact, for almost anything you or your architect can dream of for your home.

Condensation - What is it?

For each air temperature, there is a limit to the amount of water vapor the air can hold. When that limit is reached the air is saturated. Indoors, condensation forms when moisture-laden air comes into contact with a cooler surface. This cooler surface, often walls or windows, chills the air, causing water to fall out of it and accumulate as moisture.

Why CBD Windows™?

The secret to CBD Windows phenomenal performance lies in our advanced drainage and jointing technology. This technology features:

  1. Advanced drainage technology
    2. Crimped corner connectors
    3. Hidden mullion/transom junction connectors and
    4. Torsional corner blocks

CBD Windows™ gives you quality by design.

How to reduce condensation?

Sill support has always been a crucial part of window installation but is often overlooked. The detrimental effects of not having sill support bars, are not immediate but usually manifest themselves over a period of time, and hence we see an indifference to using them.

Most joinery is fixed to the building framing, through the jamb liners thereby creating a cantilevered action. This action stresses the corners, mullion joints, frame/liner connection, and eventually compromises their integrity, and in turn the integrity of the whole window system. With Double Glazing becoming more commonplace, the weight is practically doubled and the problem is further compounded. The combination now of both double glazing and cavities becoming the norm, the stresses placed on joinery have increased. With this in mind,  all windows and doors, irrespective of their size and construction/cladding type must have sill support.

What are R-values and U-values?

R-value is the resistance a material has to heat flow. The higher the R-value, the greater the resistance.U-value is the amount of heat transferred through a material. The lower the U-value, the slower the rate of heat flow and the better the insulating quality.

What is Low E/Argon-filled glass and how does it work?

Low E (Emissivity) Glass is glass with a transparent metallic oxide coating applied onto or into a glass surface. The coating allows short-wave energy to pass through but reflects long-wave infrared energy which improves the U-Value. Argon Gas is an odorless, colorless, tasteless, non-toxic gas which is six times denser than air. It is used to replace air between the glass panes to reduce temperature transfer
