lfold Gardens – Winner of Housing Design Awards ‘Masterplan Award 2020’An architecturally acclaimed development of 56 two, three, four and five bedroom homes on the former 7-acre site of Alfold Garden Centre. The development was purposely designed to provide an elusive village feel.A contemporary addition to the historic Surrey village of Cranleigh, it provides the highest standards of energy efficiency through advanced technology and the latest fabric efficient materials.With a huge emphasis on air tightness and the mitigation of thermal bridging at every juncture, Unilin Insulation’s technical team engaged at design stage to ensure specification of suitable products throughout every element of the building.Fabric First design was of particular focus in this project, Unilin’s technical advisors carried out various calculations including U-Values and condensation risk analysis.Unilin Insulation specified ECO360 MA for the floors & roofs as well as Cavitytherm360 for the walls.

Unilin Insulation partnered with Waterford City & County Council in delivering An Garrán. Our ECO360 range of insulation products for walls and floors helped achieve A-rated, energy-efficient new builds for Waterford City & County Council’s social housing development in Tramore.The project comprises 50 housing units with a mix of one-, two-, and three-bedroom homes, including accessible units for disabled residents.Designed by EML Architects, the project was constructed by local firm Nevin Construction and accommodates over 105 residents. The new development ties into the first phase using consistent materials, architectural style, and landscaping.Residents from Phase One were nominated in the Urban Neighbourhood category at the IPB Pride of Place Awards in 2023

Chester Zoo is one of the UK's largest zoos with more than 27,000 animals on a 128-acre site. Visited by around 2 million people every year, many of whom choose to eat at June's food court. The restaurant has a pavilion-like structure with an unusual roof comprising nine hexagonal peaks linked by seven flat areas.The Challenge:Water ingress through the old roof had forced shut down of the café multiple times making it necessary to renew the entire buildup. The beautifully designed trapezoidal featured roof was hugely complex.The extremely intricate design process involved SIG as system experts alongside Tapered Plus in designing the cut to fall scheme that achieved the correct U-Value for the new roof.Unilin Insulation’s Solution:Our TR/MG product is a high performance polyisocyanurate with mineral coated glass facers which is suitable for use below single ply waterproofing system. It is also compatible with partially bonded built-up felt and many liquid waterproofing systems. In addition, the insulation boards are easy to handle, cut, and secure with insulation adhesive or mechanical fixings. The specifications and quantities met U-Value of 0.18W/m2K, which is required by the updated Building Regulations Part L.  (published in 2021).

An extensive refurbishment of a 1970's dwelling into a smartly designed, low energy, light filled family home in South Dublin, Ireland.Winner of the 2022 ‘RIAI Architecture Award for Sustainability’ and the 2022 ‘Towards Net Zero Ireland Construction Awards’ in the Refurbishment Category, this South Dublin suburban project was an extensive refurbishment of a 1970s dwelling into a smartly designed, low energy, light filled family home.The project achieved the EnerPHit standard which provides a Passive-oriented set of requirements for retrofits. EnerPHit is the ultimate standard in energy efficiency for renovation projects and offers approximately the same benefits as offers the retrofit equivalent to the new build Passive House certification. The owners have experienced a significant uplift in comfort and energy economy, as well as the reduction in emissions.There were a number of technical challenges involved, such as the dig out of the old lobby and the reinforcement of the back and middle walls to ensure structural integrity. Total demolition was considered, but eventually decided against, as part of the strategy to limit impacts on embodied carbon.The overall goals were increased thermal performance, enhanced functionality and an improved building aesthetic while honouring EnerPHit and Passive principles.These goals were met throughout the entire build and especially in the decision to extend upwards rather than outwards. The decision to add an extra floor improved the building’s form factor, allowing the house to achieve EnerPHit’s passive-orientated retrofit standard. Clever placement of windows and lighting means that almost all of the house benefits from the daily sun movements.

English Martyrs Catholic School &Sixth Form CollegeThe replacement of the roof for English Martyrs School Hartlepool, part of the Bishop Hogarth Catholic Education Trust was a very complex projectThere were different roof shapes including circular and sloped roofs, multiple rooflights, and ventilated penetrations along with the requirement to avoid pooling water. In addition, work had to be carried out during school operating hours which was an additional challenge.Our solution:The supplier was very keen to use Xtrafall as a solution to the complexity of design and the necessity to minimise onsite disruption.Our Xtrafall solution is a customised cut-to-fall scheme. The system comprises of individually engineered pieces, which were installed in accordance with comprehensive laydown mapping to ensure that the overall design intent was achieved. Complex geometrical patterns are pre-formed under controlled factory conditions to provide a technically excellent, cost-effective method of providing an effective flat roof insulation and drainage solution with improved speed of installation.The project was also supported with a range of exclusive ancillary products, designed to ensure continuous thermal insulation and complete roof drainage.

Erne Campus – the World’s Largest Passive House Premium BuildingUnilin Insulation’s vast range of insulation products for walls, floors and roofs helped achieve record-breaking energy efficiency for this new build education hub. As well as being the world’s first educational building to achieve Passive House Premium standards, the impressive new campus was confirmed by the Passive House Institute as being the world’s largest building of ‘premium’ status. To complete a trio of ‘firsts,’ the 8,200 m2 project was also the first UK building to achieve both Passive House Premium and BREEAM outstanding accreditations.

Midland Heart’s approach to achieving Future Homes Standard (FHS) 3 years in advance of the legislationProject 80, the first phase of 12 homes built by Tricas in Birmingham for social homes provider Midland Heart, is complete and the residents have moved in. Built to the Future Homes Standard (FHS) 3 years in advance of the 2025 legislation’s introduction and using brick and block construction or masonry construction, the site consists of eight three-bedroom houses of two-and-a-half storeys, two four-bedroom three-storey houses and a pair of two-bedroom two-storey houses.This development of high-quality social homes is not connected to the gas grid, is highly insulated with good ventilation and is designed to provide between 75% to 80% reduction in carbon.Once residents have moved in, the homes will also be the subject of an extensive programme of evaluation by a team at Birmingham City University.

The selection of Unilin Insulation products ensured superior thermal performance and enhanced indoor air quality, meeting the project's stringent standards for sustainability and comfort.Purchased back in 2017, this Dublin building had previously been split into four bed sits. The house needed structural changes and rising damp was also an issue. Architect Brendan O’Connor devised the concept of encasing the old brick structure within a timber-framed house.There were various challenges on the project, including the search for a responsible way to deal with ventilation and airtightness. Significant structural changes were needed with everything removed except the stairs, three walls and the upstairs floorboards. The floors had Unilin Insulation’s XT/PR UF floor insulation installed along with membranes and damp proof courses, along with the construction of a timber frame to encase the existing building.The contractors rebuilt the side back wall to allow for the cantilever to support the corner unit and constructed a cavity wall extension with Unilin Insulation’s CavityTherm fullfill insulation system. The house has triple glazed windows and two wood-burning stoves.The build followed passive house principles resulting in an improvement in the building energy rating (BER) from a G (before the build) which jumped to an A3.
