This is the second instalment of our guide running from concept to handover, what needs to happen at each RIBA stage to achieve a successful airtightness test.

We need to retrofit millions of buildings with airtightness and insulation to achieve net zero. What is EnerPHit compared to Passivhaus, what are passivhaus principles? We give an introduction to highly efficient construction renovation projects.

Insulation stops heat escaping by blocking conduction. But it can’t do its job properly if heat is also being carried away by unwanted air movement.

From concept to handover, we describe what needs to happen at every RIBA stage for a successful airtightness test.

Vienna is growing a new landmark: The Wood Boutique Hotel.

In autumn 2020, we launched a brand new product. SIGA Wetguard® is used as a protection during the construction phase - especially for timber building elements.

​Flat roofs can carry more risk of condensation and moisture damage. Here’s how, by using the right design and choice of products, you can achieve a safe and dry flat roof construction using the hybrid or ’compact’ roof principle.

When it comes to vapour checks, there are some myths that are passed on from generation to generation. One myth is that there is an urgent need for a vapour barrier.

Wrong ventilation and heating by the occupants as well as leakages in the building envelope are the reasons why mould develops. Learn how to avoid this!

Most new buildings in the UK and Ireland must undergo a blower door test to measure their airtightness. Make sure you are ready on the day of your test with this handy checklist.
