Heat Recovery Ventilation (HRV) is an essential system for controlling humidity and CO2 levels in indoor environments. With airtight buildings and increased insulation, there is little air exchange between the indoor and outdoor environment, leading to a build-up of moisture and CO2. HRV systems use a heat exchanger to recover heat from outgoing stale air […]
Housing trends and the link to Passive House Design Modern house builds are changing. The key building philosophies of passive house design of correlate to the latest trends in design of individual, innovative designs and being self-sufficient or ‘off the grid’ both in terms of economic cost and home maintenance. The limited needs for heating and […]
The Science of air leakage: How much does your leaky house cost you each winter? Everyone loves to complain about how cold it is here in Canberra. And it’s true, a month of regular dips below freezing makes us the coldest capital city in Australia. Yes, even colder than Hobart! To combat this, most people […]
The Differences Between U-Values Around the World We often get asked about our U-values, and how they compare with those of other products. Firstly though, what are U-values? U-values are an important metric when determining the energy efficiency of glass windows and doors. It is a measure of both how well a window or door […]
How Does Airtightness Relate to Ventilation: A Beginners Guide When we, and a lot of the industry talk about building airtight, we often use the term ‘leaky’. But what exactly quantifies ‘leaky’ or ‘airtight’? Unfortunately, there isn’t a global standard. New Zealand’s building code defines an air change per hour (ACH) of less than 5 […]
The Importance of Air-tightness and Ventilation in Summer With the first of our summer heat waves upon us, it is important to understand the value of air-tightness and Energy Recovery Ventilation (ERV) during such hot days. But usually, air sealing solutions are framed as a solution to cold climates, keeping the warmth inside the house. […]
Low-emissivity coatings are common place in high performance window assemblies, and the benefits to including them are quite large. When justifying the additional cost, it is natural to ask how exactly this invisible coating is going to help save energy and increase comfort, and what are the key factors to be aware of when choosing […]
