Grade II Listed Anglican Church rejoices at new acoustic secondary glazing installation

Selectaglaze are a member of our Professional Trades Directory. They have recently installed 47 secondary glazing units to several large gothic arched stained-glass windows in St Philips Church, Wolverhampton for noise insulation and thermal insulation.

St Philip’s is a Grade II Listed Anglican Church in the Penn Fields Conservation Area, 3.5km south-west of the centre of Wolverhampton. In the early 19th century, Penn Fields was predominantly rural. As suburban life started to develop and progressively move west, the population increased gradually. The nearby village church of St Bartholomew could not accommodate the numbers of new churchgoers; therefore, an acre of land was given, in Penn Fields, to build a new church.

St Philip’s was built in 1858 in a Victorian Gothic style designed by Wolverhampton architects Griffin and Weller. Constructed with rock-faced stone with ashlar dressings under tiled roofs and with stunning original stained-glass windows, the church is the focal point of the village. The first vicar, Reverend William Dalton invested £3000 in exchange for the patronage and was licensed as Perpetual Curate of the Church in October 1859. The suburb grew during the early 20th century, with further domestic buildings and the extension of the church grounds to the west to form a vast graveyard.

Complete refurbishment of the church

In 1991 Wolverhampton Borough Council made St Philip’s (Penn Fields) a Conservation Area with the church forming its centrepiece. In 1996 as part of a large internal modelling project, the Church was divided to increase the multi-functionality of the building. Worship is undertaken on the upper floor, with the ground functioning as an events space.

Architects Brownhill Hayward Brown and Main Contractor Croft Construction in charge of a complete internal refurbishment of the Church in 2020.

The original large gothic arched church windows, which could not be replaced, required a solution to raise their thermal efficiency so that community activities downstairs, like children’s groups could take place in a comfortable environment.

Furthermore, it was imperative that noise egress on the ground floor, which had internal and external facing windows was kept to a minimum, so as not to disturb those worshiping on the upper floor.

A solution to reduce noise levels and create thermal insulation

Brownhill Hayward Brown got in touch with Selectaglaze to explore treatment options that would complement the church windows and be effective in preventing noise ingress and egress and thermal insulation. In addition, access to the primary windows for ongoing maintenance and cleaning was required.

Selectaglaze secondary glazing installed with standard glass can markedly reduce noise levels by up to 45dB and higher if thicker glass is used. Furthermore, secondary glazing placed in front of stained-glass panels can incorporate anti-reflective glass to preserve clarity.

The church windows are very large and together with the obscure shaping of the stone reveals on the ground floor, the installations initially looked challenging, but when Selectaglaze visited St Philip’s to survey it was found that a simpler solution could be implemented. The window reveals were deep enough to accept the standard fixing method, creating a cavity between the primary and secondary glazing to meet the required acoustic and thermal reductions. The arched windows on the first floor were bolstered by wooden frames but could still be modified with the same solution to the windows on the ground floor.

Selectaglaze installed 34 units to 11 openings, a combination of 11 Series 10 slimline horizontal sliding units and 23 Series 46 slimline fixed light units. Fixed light secondary glazing can be joined together with other products such as horizontal sliding units as over lights or side lights – best for arched windows as they can be shaped or curved to a full circle.

Reduction in heating costs

For the four stone openings on the ground floor, three Series 46 fixed lights were transom coupled to a Series 10 horizonal sliding unit. The horizontal slider was fitted in the lower half of the reveal for access to clean the primary windows, with the fixed lights coupled above to follow the tracery of the beautiful original gothic arches.  The community space has now been made more thermally insulated with the addition of secondary glazing and they should start to see a reduction in heating costs, with less heat escaping and the draughts eliminated.

A similar solution was installed in the Church space on the first floor within five wooden reveals. Series 46 fixed lights were transom coupled side by side above a Series 10 horizontal slider in each window opening with a good cavity to reduce noise egress. Events on the ground floor can happen at the same time as church services, without disturbing prayer.

“Aesthetically it all looks excellent, the thermal glazing on the external window does seem to make the community rooms considerably warmer when heated, as we have held small business meetings in them, however the acoustic glazing awaits fully testing its effectiveness as and when COVID restrictions allow.” Peter Smith, Vicar of St Philip’s Church.

The oldest steeple jack in Britain?

Peter Harknett is a steeple jack of great renown working in the counties of Sussex Hampshire and Surrey. An active Octogenarian, he has spent half his life sitting in a Bosun’s chair dangling repairing and restoring churches.

Until the lockdown in 2020 , Peter could be found assailing heights, far and wide. 

Simon Smith of W L West and Sons Ltd shares with us just a few snippets of the life of Peter, probably Britain’s oldest steeplejack, and the joy he gets from working on some of the tallest steeples in the land.

Masters of their trade

Steeple jacking really came into being  in the 16th century where travelling acrobats with their poles and ropes with no fear for heights started to carry out the work. To advertise how brave they were,  they would swing off a church spire for the amusement of local people and found there was more money in repair work than in performing. 

Steeple jacks are a fearless bunch of highly skilled workers who are masters in lead , copper, iron and timber  and masters in using ropes, levers and cantilevers and use their own specialised jargon.  

Scaling tall buildings using ladders and ropes using the Bosun Chair rather than erecting expensive scaffolding can save a huge amount of money on church spire repairs.

Perils of the job

Peter joined Bertram Mills Circus as a rigger after his National Service.  One of his first  jobs after leaving the circus to become self-employed was fixing a Gothic school tower in Surrey  which needed re-slating.  

He recalls working on the top corner bobbing in the wind when a gust caught him and the safety ‘Fall Rope’ he tied wrapped round his leg because it was getting in the way!

The gust of wind knocked him against he building and he fell over eighteen feet and the manilla rope rubbed across his shin and rubbed into the bone.  His first aid kit was a bit of old rag and insulation tape! Then back up the ladder and back to work on the Bosun Chair.

Peter’s red ladder, as shown, was an impressive sight indeed!

Oak shakes can last over 80 years

Timber roofing tiles have been around since pre Roman times and they are still very common in parts of Europe for roofs in Austria and Germany.

Peter is a leading authority on oak shakes for church spires. A shake is cleft from a roundel cross cut from a log into a disc.  They are cleaned flat so they sit well on the spire.   Using a three layer tile constructions they are nailed to a sarking board.  

Oak is very durable and can last well over 80 years if laid up correctly.  It is also very hard and off-putting to woodpeckers, birds that can easily destroy a wooden shingle spire.

Peter used to cleft his own shakes from roundels we cut in our yard but now he works with a family firm called Rapold GmbH and Co  based in Bad Reichenhall in Bavaria.  We now distribute these hand cleft oak shakes for all manner of church and building cladding.

Peter, a pipe smoker, is a great raconteur, with a wicked sense of humour to this day – ask him the off items of ladies’ underwear he has retrieved off weathervanes!

Until recently he used to cycle round the square steeple at the very top of Guilford Cathedral – no safety nets. 

“Every day is a school day,” Peter often remarks and he loves sharing his knowledge with others. What a boon to all of us involved  in conservation and restoration.

This lovely insight into Peter’s work has been provided to us by Simon Smith of W L West and Sons Ltd, timber merchants who specialise in church steeple repair and restoration.

Protecting your church during building work

In this guest post from Neal James at Panthera Security, we take a look at securing your scaffolding, building work and church from unwanted visitors. In the light of several thefts and episodes of vandalism at churches with ongoing building projects, this post is particularly timely, and we hope very useful.

How to protect your project

By their very nature churches are community buildings and we believe they should remain so. We know that most churches are over a hundred years old, and consequently are often in need of reparation works.

We know that most churches have alarm systems now in place and that is fine for normal use.

However, when work to your church becomes necessary you will invariably need to have a scaffold erected to provide safe work at height access to the building.

By providing that safe access to your contractor, you have also provided it to other, less than welcome visitors!

nsi-goldPanthera Security, Part of the Panthera Group have worked with the National Security Inspectorate on raising awareness to this often overlooked problem, and in developing NCP115 the Code of Practice for the Design, Installation & Maintenance of Scaffolding Alarm Systems. Panthera Group is proud to say that after a rigorous auditing process, we are the UK’s first company to become NSI Gold approved installers.

It is important to understand that it is the installer that is approved, and not the equipment, as some are led to believe.

Non-approved installers can still install scaffold alarm systems, but they are not required to adhere to the Code of Practice, therefore they may install an insufficient amount of detectors, thereby leaving access points unprotected.

Using NSI Gold approved installers will negate that problem. We always ensure that all vulnerabilities are covered and will issue an NSI Certificate of Compliance once the installation is complete.

Greater Manchester, STOCKPORT, St Mary (Ian Hamilton 2007) #003Ecclesiastical Insurance already recommends the use of NSI approved companies for all other aspects of security, and we have recently been in discussion over the introduction of NCP115 and have been assured that it is the standard they are looking to set regarding the installation of Scaffold Alarm Systems.

NCP115 compliant systems are now being requested as standard by many Quantity Surveyors, Property Managers and Local Authorities.

Let’s spread the word… Protect Our Churches
