PIPES, VALVES & FITTINGS Alexandra Gate gets on the network
Kingspan Kooltherm Pipe Insulation and Insulated Pipe Support Inserts have been fitted as part of the heat network on a new development, forming a key part of the Haringey Heartland Regeneration project
T
he Alexandra Gate development from Berkeley Group is being delivered by Berkeley Capital and is set to provide over 1,700 dwellings across the 12-acre site, which previously housed a gas works. The development master plan looks to convert the disused brownfield site into a thriving community with new public spaces including a large communal park and square, along with a range of one, two and three- bedroomed homes. To meet the requirements of the London Plan, the project team looked to achieve a minimum additional 35% reduction in CO2 emissions over
the standard requirements within Part L of the Building Regulations. A key part of their strategy was the construction of a site-wide heat network, which will eventually be supplied by a combined heat and power plant which is due to be installed but is not yet in place or operational. The heat network has been extended using
thermal substations in the basements of the different development blocks. Kingspan Kooltherm Pipe Insulation and Insulated Pipe Support Inserts were specified for the LTHW and DHW secondary pipework. Specialist thermal contractors, OJM Insulations, carried out the installation of the Kingspan Kooltherm Pipe Insulation across the system pipework, which comprised a wide range of diameters. The product provides leading thermal performance, allowing installers to meet heat loss targets with a minimal thickness of insulation. This was especially important on the Alexandra Gate development with a requirement for a 20% improvement over the insulation thicknesses specified in BS 5422: 2009. Ashley Miall, contracts manager at OJM Insulations commented: “We love fitting Kooltherm Pipe Insulation. The fact it’s thinner and more efficient makes it a lot easier to install when you’re working in tight spaces like the ceiling recesses. We also find the fibre-free insulation core means it doesn’t cause skin irritation for our installers when cutting and fitting it.”
In line with the guidance in CIBSE CP1 Heat Networks: Code of Practice for the UK (2020), the installers looked to ensure a continuous layer of insulation across the secondary pipework and related systems. To minimise losses at supports, they fitted Kooltherm Insulated Pipe Support inserts.
The combination of Kooltherm Pipe Insulation and Insulated Pipe Support Inserts should not only help to optimise system performance within the blocks but also reduces the risk of overheating as a result of excess heat loss from system pipework during warmer months. A BIM object for Kingspan Kooltherm Pipe Insulation is available from
bimstore.co.uk. The product holds Eurofins Air Comfort certification and both products are manufactured under an environmental management system which is certified to ISO 14001:2015. An Environmental Product Declaration (EPD) certificate for Kingspan Kooltherm Pipe Insulation can be accessed at
