Andrew Black Design relocated to the city’s Tay Street Lane earlier this year, where they transformed their former stables dating back to the 19th Century into a contemporary business hub accommodating some of the best of Dundee’s creative talent.

Relocating from their former Perth Road base, the project saw Andrew Black and his team regenerate the building, which dates back to around 1830 and is built against part of the historic old town wall.

As part of the transformation, Andrew Black Design contracted GoSustainable, whose showroom is located at the city’s Seabraes House in Greenmarket.

Callum Milne, Managing Director commented, “Following discussions and site visits, Warmcel was identified as the best insulation system for the building.  The product stands out from other insulation brands by offering  ‘Better than Carbon Zero’ environmental standards – allowing properties featuring its insulation products to significantly reduce their carbon footprint.

“GoSustainable then completed the infrared heating design calculations for each space.  With the client’s preference for ceiling-mounted heating to save space, and complement the aesthetics of the space, a full Redwell infrared heating system was recommended. Redwell gives homes and businesses an unprecedented level of control over their heating needs – increasing energy efficiency and combating the rising cost of energy.”

Prior to the works, the walls of Andrew Black Design’s premises had an ‘as-built’ U Value* of 1.6 *.  On completion of the works, the U Value was 0.32, pointing to a significant improvement in the building’s insulation and, therefore, future energy costs.

Andrew Black said, “When it came to heating the building, we had the opportunity to do what we wanted as the building was essentially a shell.  We were against putting in gas, mainly for financial reasons, and didn’t want conventional heating so Redwell ticked all of the boxes.

“The main appeal for us was that it allowed us to free up wall space. Most of the walls have desks against them so it made sense to have the heating positioned on the ceilings which were free and, essentially, wasted space. There is also the aesthetic appeal of Redwell – they are non-intrusive, very clean, light and blend into the white ceilings.

“In terms of the insulation, Warmcel was our immediate preference for a number of reasons.  Environmentally, we like it as it’s not an oil-based product which can have health implications, with the potential for small levels of gas to be released over time. Furthermore, it’s made from recycled paper which is clearly a great, green solution.  We also like its thermal values – it creates a density which is hard to get with more traditional, mineral wool-based insulation and, because it is sprayed in, there are no gaps – it’s completely foolproof.  Finally, it’s a very quick and therefore more cost-effective product to install, with GoSustainable completing the job within a day and half.

“GoSustainable really know their stuff.  Not only did we want to work with a local company but we were very much attracted by their technical expertise and the fact they offer advice on the best solution for the client, rather than simply installing a product. As architects, we have the benefit of knowing what we wanted and why, but others may not so we would highly recommend GoSustainable to ensure that the most appropriate systems and products are installed.”

*The U Value is basically a measure of heat loss through a structural element. It is calculated on the rate at which heat transfers through 1 square metre of a structure, where the temperature difference between the inner and outer face is 1 degree Celsius.
