ROCKWOOL WORKING IN PARTNERSHIP WITH PORTSMOUTH CITY COUNCIL AND ECD ARCHITECTS

Work has commenced on the refurbishment of 3, 11 storey social housing blocks at Wilmcote House in Portsmouth, a project which aims to reach the rigorous EnerPHit standard, the retrofit equivalent of Passivhaus.


Portsmouth City Council (PCC) has approved a complete whole building refurbishment of these residential blocks, comprising 107 maisonettes, which were originally constructed in 1968, to dramatically improve the building’s energy efficiency.

The project has been designed to work towards stringent EnerPHit standards and offers a whole building solution that will improve residents’ standard of living and reduce fuel costs. The key to this strategy is deep retrofit and installing multiple insulation measures, including external wall insulation, which will greatly improve the thermal efficiency of the properties and provide a stable and comfortable internal environment for tenants. The aim is to lower the demand for heating within the dwellings by 90% and extend the building’s life by a minimum of 30 years as a result of the improvements. Refurbishment will take place over a two year period, with completion expected in January 2017.

The lead architects for the project, ECD, have devised an effective retrofit strategy to super-insulate the residential parts of the block based on a combination of several ROCKWOOL insulation products and systems, including ROCKPANEL cladding façade system, a combination of REDArt® External Wall (EWI) systems, Flat Roof system and a selection of the company’s Firestopping and Fire Protection products.

The improvements aim to radically reduce the building’s demand for energy and reduce fuel poverty. Works will include insulation and cladding of each block, roof replacement, installation of triple glazed windows, extension of the living areas and more efficient heating and hot water provision. The REDArt® EWI will ensure excellent thermal performance and exceptional air tightness, thereby diminishing the occurrence of draughts, condensation and mould growth, whilst markedly improving standards of occupant comfort. The refurbishment will also improve the aesthetic appearance of the prominent block and contribute more widely towards the regeneration of the Somerstown area of Portsmouth.

Recent lessons learnt from the energy efficiency improvements carried out at the Edward Woods estate in Shepherds Bush, London, across 754 flats in three 23-storey tower blocks have proved invaluable in strategising the refurbishment of Wilmcote House. The London School of Economics and Political Science (LSE) interviewed residents of the estate during and after the renovation works for its two reports, High Rise Hope and High Rise Hope Revisited. Among the most significant lessons resulting from the research was the importance of communication with residents. The second report, High Rise Hope Revisited recommended regular community updates and ongoing support to ensure tenants feel informed of the progress of the works and develop a wider understanding of the objectives of regeneration. Residents of Wilmcote House were comprehensively consulted on the refurbishment proposals via a series of resident open days and feedback sessions and ROCKWOOL will again work in partnership with the LSE to record and assess the social outcomes of this project.

“Together, the regeneration of the Edward Woods Estate and the subsequent findings of the High Rise Hope reports provide an important model for high rise refurbishment,” comments Darren Snaith, Director of Refurbishment and Regeneration at ROCKWOOL. “High Rise Hope Revisited has shown that this type of refurbishment scheme can help alleviate fuel poverty whilst achieving marked improvements to the quality of high rise living and transforming the visual appearance of a residential block.”

The Beginners Guide to Pipe Insulation: Flexible Foams

Next up in the series we are doing on pipe insulation is "flexible foams"; a category that includes polyethylene and expanded nitrile rubber.


Polyethylene Pipe Insulation
Climaflex pipe insulation is the UK's leading brand for polyethylene pipe insulation. This is the grey foam that most people are familiar with, the kind you would traditionally find in garden centres for example. Polyethylene is the cheapest, widely available product in the market. People very often wrongly assume cheap means poor quality, this is not the case with a brand such as Climaflex. It has a thermal conductivity of 0.034 W/m.K at 0°C which is broadly equal to that of any other flexible foam, and it also has a much higher "μ factor" than other foams, making it more resistant to moisture ingress. These facotrs make it ideal for use around the home, being easy to work with and providing good insulation. 
The material can be purchased in 1m and 2m lengths, and is available in wall thicknesse…

The Beginners Guide To Pipe Insulation: Getting to grip with the basics

Our Beginners Guide series of blogs will look at the common areas of pipe insulation lagging that you will want to look at when choosing your product. This guide will be of most interest to the DIY installers, but some of our later guides will cover more complex products and areas of application.

One of the things we get asked about a lot is what the dimensions quoted for pipe insulation actually mean. You will always see three measurements quoted when describing pipe insulation; Wall Thickness, Bore Size and Length.

In the below diagram, A is the "Bore" and B is the "Wall".

Wall thickness is very simply how much insulation you have; so for example if you have 13mm Wall pipe insulation, then that means you have 13mm of insulation on either side of your pipe. This thickness is very often one of the most important part of your decision; too thin and you might not get the results you are looking for but too thick and it might not fit between your pipe and the wall.

Frost protection for domestic pipes

With the cold weather approaching we thought it would be a good idea to touch on how best to protect your pipes from frost this winter.

When dealing with frost protection on pipes inside a building your aim with insulating them is to delay the onset of freezing for as long as possible; it is not possible to guarantee a pipe will not freeze by insulation alone. The better the insulation, and the thicker the insulation, the longer you will give yourself. Under normal circumstances you aim to give yourself about 8-10 hours protection against sub zero temperatures. With pipes inside a home this is usually long enough to be sure the pipes will not freeze.


Ice formation inside the pipes will lead to an increase in pressure. As the water tries to flow this pressure will increase, and eventually will lead to the pipes bursting. A burst pipe can cause a lot of problems, not least of which is a lot of damage to your property and a lot of expense incurred.

Water regulations state that all water …
