Bespoke Sliding Over Roof Rooflight For Concrete Frame House Building Case Study

Hush Acoustics provided an effective solution to ‘noise break-in’ at a newly built primary school in Chester to ensure the internal acoustic environment was supportive of learning goals.The Huntington Primary school was designed by Cheshire West and Chester Council to cater for 420 primary age pupils and a 26-provision nursery. The former primary schools it replaced had a capacity of 120 children, but to cope with the demand of 1,200 new houses being built nearby on the former Saighton Army camp, the decision was made to build a new school to meet the requirements.An acoustic concern highlighted was ‘noise break in’ which is caused by issues such as the sound of rain falling onto the roof, which in turn would detract from the learning environment. In order to resolve this potential issue and to guarantee the children a healthy setting free from noise disturbance, we specified our Hush 10kg Barrier Mat to be installed in the roof of the building.Hush Barrier Mat is a vinyl sound barrier mat loaded with naturally occurring minerals. The product is free of lead, unrefined aromatic oils and bitumen. Designed to improve the sound insulation of existing panels of metal, wood, plastic etc., at all frequencies. The mat is normally fixed in intimate contact with the original panel. Hush barriers are particularly effective in overcoming coincidence dip resonance found in stiff lightweight composites such as plywood sheets and hollow core panels.Working alongside Kier, were Delta Group, who we supplied with 1100 sheets of our Hush 10 kg Barrier Mat. They then applied this to the roof of the school in 3x layers, to give a mass of 30 kg/m2 and improving acoustic performance across all frequencies.

Truss roof rafters and ceiling joists are typically spaced either 400mm, 450mm or 600mm apart. Given that the joist is normally 50mm wide, this gives a fairly small opening width for your loft hatch and ladder. However, there are still a wide variety of options to consider. For example, space saving concertina loft ladders, are easy to operate, providing robust and durable access to an attic. Made-to-measure folding wooden loft ladders, such as the new Quadro, are available for widths of 550mm and offer minimal protrusion in the loft space above. Visit our website for more information.

Fully compatible products from the range of TBA FIREFLY™ have been chosen to compartmentalise roof voids between apartments and communal lobbies of a large apartment building in the London Borough of Lewisham, providing 120 minutes fire integrity protection as part of a wide ranging refurbishment programme carried out earlier this year.The contract on Lewisham Homes’ Commodore Court in Albyn Road has been led by the sector specialist construction company, Mulalley & Co. with London/Sevenoaks based CLM Fireproofing carrying out the installation of the TITAN Lite™ 120:60 barrier system, in combination with Collaroll and the use of ancillary products from the FIREFLY™ range.CLM Fireproofing was founded 30 years ago by Clive Miles and has established a reputation as a leader in the fields of both passive fire protection and fire-stopping; working in a variety of sectors on projects right across the UK. A regular user of the FIREFLY™ range, many of its operatives have attended courses at the company’s premises in Rochdale to become trained FIREFLY™ installers.The Site Agent for CLM, Virginijus Pasvenskas, commented: “There was initially an intention to use a mineral wool flexible fire barrier, but the product was not tested for the scenario installed around the services such as a downpipe and it was upgraded to the use of the FIREFLY™ system by the client/project team. The installation of the TITAN Lite™ and the Collaroll to wrap the trusses and the services went very well and, as well as supplying specific details for the work, FIREFLY's technical team came to site to inspect the works. We completed our contract on schedule back in the summer.”TITAN Lite™ 120:60 has been developed for use in vertical separation or compartmentation situations, offering 120 minutes integrity and 60 minutes insulation and is able to be sealed around penetrations. It is widely specified to form fire barriers within roof voids and floor voids in many different property types, including tower blocks and other HMOs.The flexible woven material is easy to cut and fix, and is chemically treated to improve its cooling properties and therefore prevent temperatures rising in adjoining areas. The system has been fully tested to BS 476 Parts 20 & 22 and is third party certified by IFC. The six metre long rolls of TITAN Lite™ 120:60 have a minimum thickness of 6mm and are installed using special staples as well as high temperature adhesive.Employed as part of the FIREFLY™ System and also to wrap the services which penetrate barriers such as PHOENIX, ZEUS Lite™ and APOLLO Lite™, Collaroll comes in a roll which unwraps to 10m long x 300mm wide with a sewn in concertinaed skirt. The skirt can be moulded to shape to seal it neatly to the upright barrier, which is usually at 90 degrees to the Collaroll and fixed into place using the FIREFLY™ high temperature adhesive. The R31 Staple Gun and Staples are used to staple the Collaroll to itself tightly around the penetration.

Residential New Build apartment and spa area, consisting of 141 apartments.21 loft apartments required a design lead shower solution for which waterproof XPS round shaped floor shower elements, bathboards for tileable cladding of baths and XPS building boards were supplied in 12.5mm thickness for walls and 10mm thickness for floors.120 Apartments had XPS floor level shower elements featuring a drainage channel right next to the wall, a completely continuous slope right to the channel and more flexible adjustment for the channel. 12.5 & 10mm XPS building boards were used on walls and floors.This was the first installation that we know of in the UK where the boards in the shower area were fixed to the studwork solely by a versatile single component adhesive sealant (wedi 610), ensuring no penetrations through the boards. The special formulation is especially suited to waterproof butt joints of building boards, and has outstanding resistance to the elements; and to chemicals; and is also free of solvents, silicon and PCP.As an abP-approved system, the use of the adhesive sealant and XPS building boards reduces installation time by up to 50% because no further sealing is required, even in areas of high humidity.

When Make Architects needed a waterproofing solution for their latest project in the City of London they turned to IKO PermaTEC hot melt. Waterproofing such an expansive and complex roof has its particular challenges and required robust and reliable detailing. The choice of waterproofing was to perform for a minimum of 30 years, be cost effective and also contribute towards the building’s design stage BREEAM Excellent rating.

Cumbria, Northumberland, Tyne and Wear NHS Foundation Trust (CNTW) continuously strive to provide better education for the next generation of medical professionals. As such, with help from NTW Solutions they wanted to create a modern learning space for their medical education centre in Gosforth. Forbo Flooring Systems' Flotex, Modul'up and Allura Flex ranges all played a key role in bringing this project together .NTW solutions was established in 2017 by CNTW NHS Foundation Trust to provide a range of important services, across a variety of teams. They work alongside stakeholders such as NHS Foundation Trust to provide high-end project outcomes. Offering a variety of foundation placements, the medical centre will provide young nurses and doctors with a good base level of education to then move forwards in their chosen speciality. To do this there was a variety of factors to review when looking at designs.

This is a metal roof coating & refurbishment project using Liquasil's BBA Approved Metalseal 20. The project involved removing an existing cut edge corrosion treatment and re-treating with Liquasil SWT Corrosion Primer, followed by two coats of Metalseal. The whole roof was then coated with Metalseal 20 to provide long term protection against fungal growth and weathering. The unique 10 year, single-point latent defects insurance guarantee was issued at the end of the project. For details, speak to our building surveyors on 0121 709 5352

The new flagship outlet of Pioneer Foodstore in Carlisle was built to a high specification with the aim of significantly extending their client base. The planning application had to meet the requirement for a screen to conceal the roof-top services and air-conditioning plant.Italia-80V was proposed, which could be bent to a radius, to fulfill the vision for a semi-circular end to one side of the compound. The 2950mm high steel louvre panels were welded onto appropriately shaped RSA support rails at top and bottom, which were supplied with multiple holes for fixing to the posts to ensure perfect continuity of spacing. A double-leaf gate was also seamlessly incorporated by using a front fixing design.Lang+Fulton worked closely with the architect at an early stage to advise on the fixing points for the posts which would carry the screen. This ensured that the thermal barrier and waterproof membrane could be wrapped up the footings for a neat and effective installation.

Heavy rainfall on the Orkney Islands meant that the basement room of Kirkwall Air Traffic Control Tower suffered from frequent flooding, with water levels reaching 1.2m at their highest point. Newton Waterproofing and Specialist Contractor Wise Basement Systems were called in to remove the existing water and then waterproof the structure to protect it from future flooding, all in just one week.Kirkwall airport is located on the main island of the Orkneys, 10-miles off the North coast of Scotland. Presented with a logistically challenging location and a tight project timescale of just 1 week, Newton had no hesitation in recommending the expertise of Wise Basement Systems as the specialist contractor to Building Surveyor Pick Everard.Getting involved at the very start of the project, Wise were immediately able to design, advise on and install a system to remedy the 2 inches of water in the existing basement of the Air Traffic Control tower.Cavity Drain Waterproofing, or ‘Type C’ waterproofing as it is defined by BS 8102:2009 is often the most effective means of achieving a completely dry ‘Grade 3’ environment in an existing structure below ground. It was therefore no surprise that Wise Basement Systems designed a Newton CDM System for this existing basement area.To begin, Wise installed 120m2 of Newton 508 on the walls and 80m2 of the recycled Newton 520 eco to the floor, above the closed-cell Fibran XPS 500-C insulation. The drainage membranes were supplemented with a perimeter channel of Newton Basedrain, directed to a Titan-Pro sump chamber containing two NP400 Pumps to remove the water.Finally, to ensure that the system will continue to work in all eventualities, even in a complete power outage, Wise installed a backup system with dual Northstar batteries and a Victron Power Inverter.Even with a project located 10 miles from the mainland, and 1 week to waterproof a basement with only a 600mm wide access hatch, Wise Basement Systems delivered a completely dry space for the client that was also compliant with BS 8102:2009 and backed by their guarantee.

The TaskOriginally a garage for a local car showroom in the town centre, The Forum has most recently been a storage facility until the College began redevelopment of its kitchens in a 12th Century Grade 1 listed building. This provided improved and expanded catering facilities. During the works, the College still needed kitchen and dining facilities, prompting the re-purposing of The Forum.Northmores Project Management Consultants were contracted by the College to manage the project, designed by Paul Vonberg Architects, to future-proof the building.The Outcome“It was a very tricky project. Logistically, being right in central Cambridge, and during COVID, we had to ensure we were rigorous in our safe practice. Fortunately, the new internal design of the Forum meant it was easy to operate a one-way system for any internal workings making good the linings where the rooflights had been and redecorating. From a reroofing perspective too it was complex. The team at Langley devised a practical solution and were always on hand to support us with technical advice if needed.”

Established in 1976, Corfe Hills School in Dorset welcomes over 800 secondary and sixth form students through their gates each year. Since achieving Academy status in 2011, Corfe Hills have been looking ahead, keen to develop a schedule of works for building improvements that support the school’s growth and ultimately safeguard the building’s future.Over time, the existing roofs across the site had experienced continuous water ingress issues that needed to be addressed. Multiple roof penetrations from the roof lights were leaking water; the existing waterproofing system and the overlaid bituminous membrane were failing in places resulting in splits and blistering, and the metal roof had rusted beyond repair. With rain seeping directly into the classrooms below, action had to be taken to ensure the site was remedied to a safe and comfortable learning environment for students and staff.Garland Technical Manager, Paul Boole, was instructed by building surveying firm Kendall Kingscott to support Corfe Hills approaching CIF bid for the critical roof refurbishment works. An essential part of the brief was to ensure that the buildings were not only fully waterproofed but to upgrade the overall thermal efficiency, alongside securing a robust 20-year guarantee.In support of the CIF bid, Paul carried out a thorough investigation of the school’s roof assets for Kendall Kingscott, producing core sampling data, detailed condition surveys and U-Value calculations to outline a clear specification for the works required. 

The Ascent Aluminium companionway / ships ladder system was specified to create a permanent safe access route to the roof of refrigeration units within Aldi stores for maintenance personnel.

Newton System 500 fulfils all Listed Building requirements in this Georgian Manor House. Newton Pumping Systems installed to manage waste water, including two Newton Titan pumps and battery backup systems.

refurbishment project posed particular challenges in respect of the flat roof, which consisted of a solid concrete deck, followed by screed laid to falls, a thin dense concrete layer and three bituminous membrane layers. The new roof specification required the application of new insulation to upgrade the thermal performance and a new single ply waterproofing membrane. Due to the location of this project and the presence of existing bonded layers, adhesive application was ruled out at an early stage and a mechanically fastened solution was sought.Initial pull-out tests confirmed that fixing was required through the existing screed and direct into the concrete deck. With the roof’s high exposure rating and dimensions, wind load calculations indicated that only corner and perimeter zones should be used, which demanded a high density of fasteners in these areas.the solutions provided by SFS included its TIA adjustable fastener in combination with the isoweld® 3000 heat induction welding system. This fastener system included specially coated isoweld® stress plates combined with 230mm and 300mm FI-R-20 sleeves and the 150mm long TIA fastener. These were installed through the insulation and screed layers and were mechanically fastened into the concrete substrate.The fasteners were applied through the insulation boards in a field fix grid pattern followed by the Protan SE single ply waterproofing membrane, which was then installed using the specialist isoweld® 3000 system, welding the membrane directly onto the isoweld® stress plates. This provided an extremely secure fix, without having to duplicate fasteners, and the associated drilling, and without the need to penetrate the waterproof membrane as would be necessary on seam fix systems.

Armourplan PVC and Recticel Insulation by SIG Design Technology were selected for a 12,000 m2 roof to a bottling plant in a rural location on the outskirts of an historical Derbyshire spa town, known as Project Merlin. The FMCG company chose to build the new facility away from the site of the natural spring, piping the water some two miles out of town to this green field bottling and distribution site.

Pinewood Studio in Cardiff may be the location where Dr Who regularly saves the Universe but there was no intergalactic crisis when the building’s 16,000m2 roof needed to be refurbished recently. Instead, Sika Liquid Plastics’ Sikalastic® 625 cold applied liquid membrane provided the ideal solution to protect the building from Wales’ famously wet climate while enabling a low key project that didn’t disrupt filming on the many Hollywood movies and acclaimed TV shows filmed there, which have included James Bond, Harry Potter and Sherlock. https://www.youtube.com/watch?v=ayB4ekA7FfM&feature=youtu.be
