Bespoke heat pump

Octagon required an efficient heat pump solution designed to handle a large heat load for their luxury new build - Crossacres on the Wentworth Estate. Nu-Heat designed and supplied a bespoke heat pump solution. The NIBE Dual ASHP 2300 20kW was chosen to meet Octagon’s requirements and is particularly suited to larger, residential applications. The advanced controllers allows for individual control of multiple swimming pools and boiler back-up, while NIBE Uplink enables remote access to the heat pump for the end user.

Joyner bolt

Joyner has launched an alternative to the traditional coach bolt to the residential and commercial construction market. The Joyner Bolt replaces the rounded head of a coach-bolt with a flat rectangular head with angled “teeth” which grips the wood around the drilled hole. The shank of the bolt slides through the hole and as the nut is tightened, the teeth bite into the timber resulting in a tight, non-twist joint that is perfect for joists, roof trusses, stud walls and a host of other wood-to-wood or wood-to-metal situations.

Waterproofing

A new-build property in Surrey had a large basement area which needed to be waterproofed to meet BS8102 requirements. Maclennan UK was commissioned to design and install a cavity drain waterproofing system. Newton System 500 was chosen for the project as it provides a maintainable waterproofing solution - and thus meets the requirements of BS8102. Newton 508 Cavity Drain Membrane was applied to all internal walls, and ingressing water was collected into the Basedrain channels throughout the perimeters of the wall/floor junction and pumped out to safe drainage using the Newton Titan-Pro pumping system.

Cantilever staircase

Canal Engineering has recently completed a cantilever-staircase project in a London penthouse apartment. The staircase incorporated hidden metalwork within the wall. Once installed, it formed solid American white oak timber box treads sleeved over the channels, which matched the chosen timber flooring throughout the property. Throughout the penthouse apartment, 15mm low-iron toughened-glass balustrade panels were installed as the staircase balustrade and around the first and second floor openings. To finish, satin-polished, stainless steel handrail was installed as a top rail to the glass balustrade and wall fixed for the opposing handrail running up the staircase.
