How Cottage – Internal Walls


How Cottage – Internal Walls

How Cottage

How Cottage is located just outside Keswick in Cumbria. It’s a traditional Slate Lakeland Cottage built in the Mid19th Century. The owners of the cottage decided to completely refurbish the building and add a large extension, which would make the building twice its original size.

The owners of How Cottage were advised by their architect, at 2030 Architects, that insulation was a must for their refurbishment, to reduce both heat loss and carbon emissions. However, one of the walls backs straight onto a public road, which means that this wall could not be externally insulated. Therefore insulation to the interior of the cottage became essential.

2030 Architects turned to Vacutherm to supply Vacupor, which is the thinnest Vacuum insulation on the market. This means that the wall is fully insulated, which not only saves you money on heating, but also minimal space is lost in the home.

Vacupor was used in 3 different areas of How Cottage, including, 1. Stair way 2. Utility room 3. Window reveals The brief was to improve the insulation levels to better than the current building regulations. This was achieved very effectively when using Vacupor as it is a complete internal insulation system which achieves incredible U-Values. In this case 0.27W/m2K with just a 15mm thick vacuum panel.

PIR insulation would not have been viable for How Cottage, because it would be too thick to achieve the required U-Value. This would have meant that the stairs and rooms would have been unusable.

The face of the Vacupor panel was over board with Fermacel which is a dense Gypsum based board, this means that there is no need for plastering. This was something that was extremely helpful with How Cottage refurbishment. It meant that time was not lost on skimming and waiting for plaster to dry. In fact decoration was started the day after the Vacupor was installed.
