USE OF FOAMGLAS ® FOAMGLAS ® cellular glass insulation is guaranteed to maintain all its physical values for the lifetime of the building.

PREPARATION AND INSTALLATION In order to provide its full load capacity FOAMGLAS ® PERINSUL ® is incorporated into the structure, laid into a soft mortar on a flat and level support with vertical joints tightly-butted. To achieve maximum adhesion, the blocks are moved to-and-fro in the mortar so that it is squeezed out on all sides. PERINSUL ® must be kept horizontal. The first layer of bricks or blocks on top of the FOAMGLAS ® PERINSUL ® must also distribute the load uniformly over their full surface. (Hollow or indented blocks should not be used for this layer unless they are inverted to present a flat face and the cavities are infilled with concrete).

USE OF FOAMGLAS®
FOAMGLAS® cellular glass insulation is guaranteedto maintain all its physical values for the lifetimeof the building. It does not deteriorate with ageand its thermal properties remain constant.FOAMGLAS® is totally non-combustible andcannot contribute to a fire nor give off toxic fumesor smoke; it is also totally free from HCFC, HFAand pentane.
Perimeter Insulation to EliminateThermal Bridges – New Build
APPLICATIONSFOAMGLAS® PERINSUL® has an compressivestrength at break point 2.5N/mm2 and, whena safety factor is used, it typically has a load bearingcapacity of 1 N/mm2 without compression ordeformation.It can therefore be installed at the base ofstructural walls in the following situations:– inner walls (block or brick)– outer walls (block or brick)– parapets– access points– support areas for roof trusses.
PREPARATION AND INSTALLATIONIn order to provide its full load capacityFOAMGLAS® PERINSUL® is incorporated into thestructure, laid into a soft mortar on a flat and levelsupport with vertical joints tightly-butted. Toachieve maximum adhesion, the blocks are movedto-and-fro in the mortar so that it is squeezed outon all sides. PERINSUL® must be kept horizontal.The first layer of bricks or blocks on top of theFOAMGLAS® PERINSUL® must also distribute theload uniformly over their full surface. (Hollow orindented blocks should not be used for this layerunless they are inverted to present a flat face andthe cavities are infilled with concrete). Shouldcutting be required, first remove a narrow strip ofthe facings with a sharp knife and then use atoughened saw for the PERINSUL®.NB: FOAMGLAS® PERINSUL® blocks shouldnot be tapped or struck with any tool.
BUILDING REGULATIONS,Part L & J
All FOAMGLAS® systems meet the requirements ofBuilding Regulations, with regard to air tightness of thebuilding, the avoidance of cold bridging and sustainableconstruction. FOAMGLAS® systems will continue to fullyperform for the lifetime of the building.

DIMENSIONS AND THERMAL
PERFORMANCEFOAMGLAS® PERINSUL® blocks are 450mm long,available in various thicknesses and widths asshown opposite.Blocks are bitumen coated on all faces.FOAMGLAS® PERINSUL® has a thermal conductivityof 0.055 W/mK at 10ºC.In a single leaf wall, a FOAMGLAS® PERINSUL® block110mm wide will exceed the requirements inPart L & J of UK Building Regulations and providea U-value of approximately 0.39 W/m2K.
PHYSICAL PROPERTIESCompressive Strength(average at breakpoint) : 2.5N/mm2
Load Bearing Capacity(safety factor applied): 1 N/mm2
Density: 220kg/m3(± 10%)Coefficient of thermalexpansion: 9 x 10-6/KThermal Conductivity(± 5%) at 10ºC: 0.055FireNon-combustible, no toxic fumesDimensional stabilityPerfectResistance to water-vapour transmissionµ = ∞28 dB for 100mm thicknessA safety factor is used in conjunction with thephysical properties of FOAMGLAS®; a factorof 2.5 or 3.1 is frequently used, a structuralengineer will provide your design requirements.
Ecologically FOAMGLAS® cellular glassmeets the most stringent demands foran environmentally sound material.In manufacturing, 66% post-consumerwaste glass is utilised, combined with amanufacturing process which minimisesenergy. The result is an insulation materialwhich provides high performancethroughout the lifetime of the building,through to its eventual disposal as aninert material or its re-use. FOAMGLAS®
is totally free from HCFC, HFA andpentane, exceeds the requirements ofthe Building Regulations and hasAgrément Certification.

Ψ-VALUESThe calculation is based on the buildingelements; this gives a design value of theΨ-value (heat loss coefficient for thermalbridge (W/mK) with reference to the length ofthe element).Using FOAMGLAS®, Ψ-values can be achievedof zero or even negative values. Thecalculation follows the European regulationsfor thermal energy saving, taking intoconsideration the heat loss by thermal bridgesin an optimal way.

TYPICAL INSTALLATION DETAILS
This thermal image shows the major cold bridge and high thermal loss at thejunction between the floor slab and wall construction.
Fire tests carried out in Germany achieved Class F60, giving 60 minutes fireresistance in a wall construction. This was achieved without additional structuralelements being applied to the wall.

Fully waterproof, PERINSUL® forms a capillarybreak reducing the risk of moistureprogressing up the wall.
5
Building blocks or bricks are installed on topof the row of PERINSUL® as the wallconstruction progresses.
