Low Energy Construction

At Low Therm Solutions, we work with self-builders and small developers providing advice and support as well as material and product components to create the complete ‘shell’ of a new low energy home.

Whilst our original SIM wall was developed for new buildings we are also increasingly involved in refurbishment projects where owners are keen to reduce energy consumption and create a healthier and more efficient living environment.
Despite the fact that low energy building is the ultimate aspiration of many self-builders and small developers/contractors, many of our customers are uncertain and unsure about the measures needed to build sustainably. Our team are here to help guide each of our customers through the process, ensuring that their architectural plans and drawings are adapted in such a way that all low energy objectives can be met.
We provide advice, design services and support from very initial stages through to planning and construction. From low carbon living to the ultimate passive house, we are able to help each unique green build objective become reality.
