Wall Insulation

When you consider that your walls are the largest sqm surface area of your home that is exposed to the raw outside elements, it is easy to understand how they influence your inside environment. Floors and Ceilings are not subject to the impact of rain and high wind speeds which can cause a wind chill factor on your walls.

Reasons to insulate walls are to prevent heat loss, eliminate air movement and prevent internal wall condensation.

Because walls are a large surface area they need to be insulated properly and effectively. Unlike floors and ceilings there is only one opportunity to get it right for the rest of your homes life. We now have three levels of wall insulation product technology to take your wall insulating project into the future now.

1. Low Density Insulation (common insulation). Designed to slow down heat loss, can be very effective as long as you use the right product and is installed perfectly.

2. Medium Density Insulation (more fibre/weight per sqm). A new breed of insulation product designed to reduce air movement within the insulation, therefore maintaining stated R-Value during high air moment conditions, Can also offer some thermal storage due to its increased mass. Made in the form of a pad for a friction fit between 400 and 600 studs. Perfect for DIY guaranteeing a perfect installation.

3. High Density Insulation (higher fibre/weight per sqm). A newer and enhanced technology process that uses high quantities of recycled plastics and recycled polyester fibres into very high densities. Has tremendous bounce back (loft retention) and eliminates all air movement through the fibre, Made in the form of a pad that has enhanced thermal storage properties. Excellent for retrofits in older homes to add more mass to our light timber framed construction to maintain internal temperatures for longer.  Click here for high density photos.

Wall Condensation

This occurs when warm moist inside air meets uninsulated cold wall cavity air and is at the right moisture content to reach dew point. Condensation will then form on the inside of the framing without you knowing it. This is a building physics condition that is being recognised around the world and is called interstitial condensation. Insulating the wall raised the wall temperature beyond the dew point therefore preventing the possibly very damaging condition.
