Insulation Boards for a timber frame apartment building

Products Used: TB4000
Sector: Housing

Situated in Kendal's flourishing community on the edge of the Lake District, the luxurious riverside Kentgate apartment building is a stylish example of modern design. Built with ethical standards in mind, designers opted for a sustainable timber frame solution that made use of Celotex' excellent thermal performance.

Built on the banks of the river Kent, the development was positioned so that residents could enjoy views over the water or towards the hills of the Lake District some three miles away. Developed by house builder Russell Armer, designed by SMC Architects and built by Thomas Armstrong (Construction), the apartments are especially eye catching and built to appeal to the town's burgeoning professional community.

The project was marked by a commitment to the principles of sustainable construction and particular attention was given to selecting energy efficient heating. An essential part of this system was the use of highly thermally efficient Celotex TB4000 insulation integrated into the structure's prefabricated timber frame to create an effective thermal shell that would supplement the energy savings of the green heating system.

A highly challenging project, enhanced by its town centre location and position next to the river deemed a SSI (Site of Special Scientific Interest), the development, features 46 apartments, a number of retail and commercial units and a basement car park for residents and also the neighbouring hotel. Built from in-situ concrete up to first floor, the timber frame and Celotex insulation was used to create the structure of the remaining building.

The timber frame that provided the skeleton of the apartment block was supplied by Eleco Timber Frame. These patented open frames, manufactured from timber from sustainable sources, use nail plates to create a more rigid structure whilst reducing material costs. Factory produced, the timber frame solution offers a modern method of fast track construction whilst meeting the project's sustainable targets.

The frame was a perfect match for the architect-specified Celotex insulation boards. With the timber frame reducing the need for wooden supports beneath ceiling beams, the insulation creates a more thermally efficient building envelope. This is because, rather than slotting insulation into many timber cavities, creating gaps and risking a non-airtight thermal envelope that would transmit cold, the insulation could be taped together in the larger spaces between load bearing beams, forming a highly effective thermal shell.

The timber frame system also enables the creation of a slim wall profile which was further enhanced by the thin, yet high performance Celotex insulation boards. The Celotex TB4000 boards are available in a range of thicknesses, from 12mm to 45mm, making it the thinnest polyisocyanurate (PIR) insulation on the market. Together with the timber frame, this enabled the creation of more saleable floor space.

The first PIR insulation to be rated A+ when compared to the BRE Green Guide 2008, the Celotex TB4000 boards provide more effective insulation per mm than most materials, including mineral wools. This means that the foil faced 45mm boards play a crucial part in reducing the Kentgate development's need for heating, thereby lowering costs and reducing carbon emissions.

The boards also have low Global Warming Potential and zero Ozone Depletion Potential. Combined with astonishing longevity, this means that Celotex insulation is an ideal addition to any project looking for environmentally conscious insulation.

The apartments at Kentgate are being swiftly taken by residents who want to move into the well conceived development. Featuring bespoke interiors planned by top designers and situated in a beautiful location in the heart of Kendal's cosmopolitan yet traditional centre, the flats are widely regarded as hot property - all the more so due to the amazing thermal properties of Celotex' environmentally beneficial TB4000 insulation boards.
