 | | FERMACELL IS DRY SCREED CHOICE FOR BRUNSWICKA | | | Fermacell | | 18/12/2006 | | | Brunswick Estates has chosen Fermacell board as the dry screed overlay on underfloor heating systems at its Claremont Hall development in Huddersfield.
Brunswick specified the Velta Siccus hot water underfloor system with Fermacell 2E22 elements as the dry screed overlay. The 2E22 floor elements, each comprise two pre-laminated layers of Fermacell 12.5mm board with lapped edges, are simply laid as a floating floor on top of the Velta system. Fermacell floor elements have so far been installed in two show apartments with a total surface covered of around 100m
Claremont Hall is a Grade 2 listed Georgian gentleman's residence that Brunswick has refurbished and converted to provide ten luxury apartments.
The development combines refurbished period architecture with complementary new build development. Each apartment is individually designed, based on the layout of the Georgian mansion, and takes its unique identity from the original plans and layout.
Underfloor heating is rapidly becoming the norm in this type of development, and as Brunswick director, Alan Whyke, explains the dry screed option using Fermacell board offers a number of advantages.
The Velta Siccus is a completely dry fit floor heating system that is equally suitable for new-build and refurbishment projects. Since no wet screeds are required it can be installed very quickly and simply, with no waiting time before the floor covering is laid.
The Fermacell floor board is strong so it can resist impacts, point loads up to 2.5kN and general wear and tear. It also has a low thermal mass that makes it effectively transparent to heat, making the system very quick to respond. These two factors contribute to an underfloor heating system with a very shallow profile that can add as little as 45mm to the height of the floor.
Compared to other dry overlay materials, such as chipboard, Fermacell provides much better soundproofing too - providing an effective barrier to both airborne and impact sound. This makes it an ideal material for multi-occupancy developments. These properties result from Fermacell's unique structure. It is a fibre-reinforced gypsum board manufactured from a high proportion of recycled materials in a fully recycling process. As well as its strength, acoustic properties and thermal transparency, it also offers fire and moisture resistance.
Says Alan Whyke, 'Fermacell was recommended to us by Velta and we are pleased we took their advice. Installing it was a very quick and clean job, with no need to wait 28 days for a wet screed to dry. The Fermacell has the strength we require for it to be able to stand up to wear and tear and heavy point loads.'
Fermacell is a brand of Xella Dry Lining, a division of Xella, the international building materials manufacturer. In the UK, Xella Dry Lining offers Fermacell floor, wall and ceiling systems and the HD exterior board system. | |
