Thermoblocks maintain continuity to ‘wrap’ for bespoke Bristol house build


Already well accepted across the UK construction industry as a quick and effective means of addressing cold-bridging around the perimeter of building oversites, or beneath parapet walls, Bristol based architects Marshall & Kendon have sought technical advice from manufacturer Marmox, regarding the integration of its Thermoblocks into the exterior insulation ‘wrap’ of a bespoke, near-to-zero timber frame construction. The founding partner of Marshall & Kendon, Jeremy Marshall, confi rmed: “It is our habit as a practice to always run insulation across the outside of the structure, wrapping them rather than putting it within the timber frame. In this instance, Thermoblock enables us to make the layer of insulation continuous as it passes through the loadbearing structure, while the airtightness membrane is continued up the outside of the sheathing boards. Our structural engineers were satisfi ed that Thermoblock offers more than adequate compressive strength and our main contractor, who is very innovative in their approach to timber frame construction, agreed to trial them.”

A family-run fi rm from Surrey, which specialises in loft conversions and the creation of bespoke garden rooms, is making extensive use of SterlingOSB Zero from panel product manufacturer, West Fraser, based on the board’s value, performance and ease of installation. MB Loft Conversions, based in Caterham, was established eight years ago by Mark Bell. Typically, the company completes up to a dozen loft conversions and other projects each year. Mark purchases his SterlingOSB Zero from Selhurst Timber and other builders merchants’ local to clients’ properties. While he mainly prefers to use 18 mm tongue and groove boards for their strength and excellent alignment when laid, some of MB Loft Conversions’ builds also use quantities of 11 mm (square edge) SterlingOSB Zero. Mark Bell commented: “There is a number of reasons why we prefer to use both West Fraser’s 8x4 and 8x2 T&G Sterling OSB Zero, apart from it being a product I’m very familiar with. We know we can rely on the quality, while the 18 mm T&G boards are like gold when it comes to doing fl at roofs and make a really good deck.
