In this episode we discuss, why we like a big eaves overhang? Beyond the look, a deeper overhang keeps walls sheltered, helps finishes last longer and protects windows and sills from driving rain, while cutting down splashback at the base…
Heatwaves are no longer unusual in the UK, and buildings designed to keep heat in during winter often struggle to keep it out in summer. Chris and Andy work through what helps, from simple shading and night purging to airtightness,…
In this episode of the ‘Can I Just Ask?’ series; Chris and Andy take on flat roofs, the most moisture sensitive roof construction there is, and the three ways we specify them with wood fibre. The ventilated build is the…
Watch this episode of ‘Can I Just Ask?’ to find out how to replace windows after internal wall insulation has already gone in. Ideally the existing building is made retrofit ready first, with the windows upgraded before any insulation work.…
In this video we look at what happens to internal wall insulation when a property floods. The real problem isn’t the water itself, it’s what the water brings in with it, and that changes what has to happen to the…
We all know the feeling of walking into a home that just feels right, but it’s harder to put your finger on why. Here’s an interesting one: two homes can be sitting at exactly the same internal temperature, yet one…
A tight retrofit budget means you can’t tackle everything at once, so knowing where wood fibre insulation earns its place first really matters. It’s one of the most common questions we get asked when someone’s approaching a project, and the…
Retrofit projects often throw up variable specifications — sometimes something’s already been installed and you’re working around it, or there’s pressure to reduce overall build-up thickness. So can wood fibre insulation be combined with PIR or other synthetic insulations? In…
In this episode, Chris and Andy look at why positive input ventilation (PIV), despite being widely used in retrofit projects, generally isn’t recommended alongside internal wall insulation (IWI). Andy explains that PIV works by pressurising the indoor space to push…
