We often get asked why our renders are lime and not cement based. People query why breathability matters if you’re rendering on to impervious materials and why you'd pay more for no clear benefit? We supply Baumit renders because they are lime based, technically very good and high quality.
When installing windows, particularly windows with no visible fixed frame such as Velfac windows, it's really important to get the detailing correct. Few manufacturers seem to offer details for awkward junctions such as sill corners which can lead to poor or leaking installations. We regularly get asked how to detail windows when installing our insulation systems so we’ve put together some key points...
One area that is sometimes overlooked whilst on site is the weather tolerance of the materials being used. The UK is well known for it’s high rainfall and for it’s ability to surprise, at any time of the year. We believe that when building, materials should be robust enough to withstand the weather and being handled by installers.
Can you suggest any materials for internal insulation of an old building?
For internal insulation you could use our UdiIN or UdiINRECO systems which are both wood fibre insulation board based system that are fixed to the interior of the walls to insulate.
How does UdiRECO compare to Polystyrene or PIR boards?
The 80mm UdiRECO board has an overall conductivity of 0.044 W/m2K so would be equivalent to 60mm of grey EPS or around 40mm of PIR. However, neither of the other two are able to manage moisture...
