Creating a Passivhaus home Balancing sustainability and style, Sort Trae is the culmination of a retired architect’s vision for a home and creative space that blends into a South Yorkshire hillside. HEM Architects helped the client to bring this dream to life, using Knauf Insulation’s glass mineral wool insulation to achieve the incredibly high Passivhaus standards for energy efficiency. Low carbon and high comfort The client envisioned a sustainable build using Passivhaus, a voluntary standard for designing and building properties with very low energy consumption, that offer high levels of comfort for their occupants. To achieve this, the levels of air tightness and thermal performance far exceed those mandated by building regulations. FrameTherm® Slab 32 was friction-fitted within the 140mm thick timber frame walls on the first floor, while DriTherm® Cavity Slab 32 was used to fill the stone-clad masonry cavity walls on the ground floor.  “We try to specify fully filled masonry cavity walls where possible, sometimes up to 200mm wide, to maximise the use of mineral wool insulation. It pays dividends for the client”, explained Liam Seaman, Architectural Technologist for HEM Architects. Thermal performance is critical to the Passivhaus approach. The FrameTherm® Slab 32 provided a calculated U-value of 0.137 W/m2K in combination with the black timber frame wall and cladding. For the masonry cavity wall on the ground floor, a fractionally higher U-value of 0.138 W/m2K was achieved using thermally broken wall ties and DriTherm® Cavity Slab 32. This has contributed to Sort Trae’s exceptional thermal efficiency. Because glass mineral wool is flexible and fibrous, slabs knit together and adapt to minor imperfections in the substrate. This tight fit contributed to an overall air change of 0.54 ach (air change per hour), comfortably below the Passivhaus standard of 0.6 ach, meaning the property is air-tight while still providing good ventilation. Sustainable practices Liam explained his reasons for choosing Knauf Insulation, “The alternative products are often oil-based and the application of these is outweighed by the environmental impact of their production and lifecycle.” Both FrameTherm® Slab 32 and DriTherm® Cavity Slab 32 are manufactured with ECOSE® Technology, Knauf Insulation’s unique bio-based binder that contains no added formaldehyde or phenol. The binder is made from natural raw materials that are rapidly renewable and is 70% less energy-intensive to manufacture than traditional binders. Knauf Insulation’s glass mineral wool insulation contains up to 80% recycled content, mostly glass bottles and jars. It is also compressed so more product can fit per pack or pallet, and less packaging is used. This means there’s more product per truck, resulting in fewer vehicles on the road, and less packaging per m2 of insulation. Achieving the Passivhaus standard In collaboration with HEM Architects and other suppliers, the client has created a stunning home and an inspiring set-up for her loom-weaving workshop. “It is general practice for us to specify Knauf Insulation as standard because we find the product information available to be really clear and useful”, Liam added. Knauf Insulation’s practical, detailed product information made it HEM Architects’ first choice to achieve the Passivhaus standard for thermal performance. 

Georgina and Matt were undertaking a refurbishment to their family home in Surrey, including a new annexe, when they approached us about our range of timber windows and doors.The age of the original building dated back to the 16th century, with both Regency and Edwardian additions, and so finding timber windows that helped to retain and enhance the original character of the property was a priority.Spring Sash windows from the Conservation Range were recommended for most of the home, featuring concealed pre-tensioned balances. This offered Georgina classic period styling but also ensured the house benefitted from the high performance offered by a modern double-glazed window.Conservation Range Casement windows were used for the rest of the property, alongside Spring Sash products offering traditional sightlines - ideal for period properties.Georgina also wanted to ensure that the new outbuildings retained a traditional look, so we created a bespoke ‘sunrise’ feature window to give it interest and kept the styling in line with the rest of the renovation.Antique brass ironmongery and a ‘Wimbourne White’ paint finish, complements the classic look throughout.Georgina explains;“When I approached Mumford & Wood, I told them I felt a ‘Jane Austen’ period feel would fit well with the main era of the house. After witnessing the quality and elegant style of the Conservation Range at their London showroom, I felt confident that my Regency vision with a mixture of Spring Sash and Casement windows could be fulfilled, and I was thrilled with the end result. I wouldn’t hesitate to recommend Mumford and Wood to anyone.”

Road users in Kensington Church Street in Bayswater, are now enjoying a peaceful commute after Openreach and Centercomms Ltd replaced a long-standing failed access cover using UltraCrete’s market-leading access cover reinstatement materials.BackgroundClient Openreach, and contractors Centercomms Ltd, were once again required to repair a failed ironwork chamber on a busy central London street – the longest standing failed unit on their work stack.The ChallengeThe troublesome unit was located on Kensington Church Street in Bayswater – an extremely difficult and busy area in Central London. Working in London can be challenging as traffic management permits can be difficult to obtain and, due to heavy traffic, all work must be completed within 9.30am – 3.30pm.As well as a tight turnaround, upon arrival it became clear very quickly that chamber was damaged and the brickwork needed to be excavated.The SolutionWith this in mind, contractors Centercomms Ltd, working for, and on behalf of, Telent, chose to use UltraCrete’s market-leading maintenance solutions to replace the failed unit. UltraCrete has a reputation of providing the industry with expert and approved materials that reach required compressive strengths very quickly, helping operatives to complete installations before the 3.30pm deadline.To begin, the damaged brickwork was removed and timber shuttering installed using UltraCrete QC10 F. This fast, strong and easy to use flowable concrete provides an extremely robust repair in just 20 minutes.Using the SG Pam Install Plus frame installation system, Centercomms Ltd carefully placed the frame and used a string line to ensure it was level with the existing road surface.Once in position, Envirobed® CD534 Red high performance bedding mortar was applied to the inner face and chamber top and the timber shuttering was then placed 50mm beyond the flange.After Envirobed® CD534 Red had fully cured, Envirobed® CD534 Flowable Red was mixed and poured to fully bed and encapsulate the frame to a minimum depth of 35mm.To complete the installation, operatives returned the lid into position, applied SCJ seal and tack coat spray to the vertical edges of the existing road surface and frame ahead of the asphalt reinstatement.ResultsThe entire installation took just two and a quarter hours to complete, much to the delight of the client, contractors and road users.

Jesus Church had Selectaglaze secondary glazing installed by partner Fenestral, to raise the thermal efficiency of its thirteen lancet shaped stained glass windows in the north and south walls. The heating of the church is run on an antiquated oil-fired system which takes time to warm up the building. Once heated, a great deal of the energy was lost through the original windows. Special timber grounds were produced with enlarged gothic curved heads. By fitting the units nearer to the reveal, the primary windows are beautifully framed and the 13, Series 41 side hung casements have clearance to open.
