PreSetsTOTAL CONTROL IsoStone thresholds Strong, insulating thresholds made from featherweight glass-fibre plastic for PVC façade elements 2 3 ISOSTONE THRESHOLDS FOR PVC FAÇADE ELEMENTS The BUVA IsoStone ® series of thresholds for PVC façade elements are made from glass-fibre reinforced plastic (GRP). The profile consists mainly of pure glass and the structured surface is coated with UV-resistant corundum granules. The thresholds are also available in bluestone-look. The base plinths are made from polyethylene. Important benefits are the low weight, enormous strength, break and scratch-resistance and the minimum expansion coefficient.

2 e patented threshold is more than 10 x l
e patented threshold is more than 10 x lighter than, for example, natural stone thresholds and therefore significantly easier to handle during manufacture, transport, processing and installation. Strength The glass-fibre reinforced plastic is practically unbreakable, dimensionally stable and stronger (tensile strength) than, for instance, aluminium. The coating provides a very longwearing finish. Expansion coefficient The damp-proof thresholds have a minimum expansion coefficient (the same as concrete) and hardly shrink or swell at all during changes in temperature. 1 metre of BUVA IsoStone threshold swells or shrinks by only 0.4 mm at a temperature difference of 50° Celsius. Thermal insulation With its low U-value of 2.2 W/(m 2 .K), the BUVA IsoStone threshold provides a reduction in the Energy Performance Coefficient (EPC). The insulating threshold prevents cold radiation in winter. 5 The BUVA IsoStone

This threshold is also designed for use under fixed windows. Dimensions: 130 x 55 mm The PS0500 thresholds are finished smooth or with a groove for the stop upon request. Base plinths The following base plinths are available for the various profiles on the system houses of the PS0500: • End base plinths with groove • End base plinths without groove • Intermediate bas

This threshold is also designed for use under fixed windows. BUVA IsoStone PS0500 thresholds are also used under profile systems with changeable frames (frames that make an interior frame an exterior frame).

Base plinths are not needed. PS0600 threshold PS7055 threshold 8 Application possibilities Profiles of PVC façade elements are either recessed or non-recessed. BUVA IsoStone thresholds are available for both profile types on all system houses. Recessed profiles Two thresholds are available for the recessed profiles on the system houses, the PS0500 and the PS0600. Non-recessed profiles The PS7055 is specifically designed for non-recessed profiles. To be used under all non-recessed profile systems on all system houses. Joints The joint between the frame upright and the BUVA IsoStone PS0500 or PS0600 thresholds is achieved with a base plinth that is specifically designed for the profile system. Dowel pins are installed in the bas

e plinth to ensure the frame upright is correctly positioned above the threshold. Packing is placed between the frame upright and the threshold for an air- and water-tight connection. The threshold/base plinths also have holes that correspond with the profile system to attach the threshold properly under the frame uprights. Base plinths are supplied with dowel pins and packing. Drawings are available of all the possible combinations of the BUVA IsoStone thresholds system in every system house. These drawings can be downloaded via www.buva.nl Double doors BUVA IsoStone thresholds are also suitable for double doors. Contact BUVA to find out more about the possibilities. Filler strips Variations of the BUVA IsoStone threshold are achieved with AM strips, delivering a solution for almost every system house.

Recessed profile Non-recessed profile 9 Order form BUVA IsoStone thresholds for use under PVC façade elements can be ordered using a digital order form. All the relevant information regarding the plastic façade element under which the IsoStone threshold will be installed must be supplied in the form. Relevant information • Number of thresholds • System house • Profile type • Threshold model (smooth, grooved or a combination of both) • Number of between thresholds • Divisions • A-sizes (length from the edge of the threshold to the middle of the between threshold / end of threshold) When the form is completed a code is created which provides the model of the threshold, for example XX-Y-PS0500-A-2-DI-VI. • System house XX • Profile type Y • PS0500 threshold &#

PVC façade elements featuring a BUVA IsoStone threshold meet this demand. Fire-resistance The resistance to fire penetration and fire spread of door constructions m

ust comply with the performance requirements in the Dutch Building Code. A survey carried out by Efectis regarding the fire resistance of door constructions has shown that the BUVA IsoStone thresholds have no adverse effect on the fire resistance of these constructions. Burglar-resistance According to the Dutch Building Code, the Dutch Police Hallmark for Safe Homes (PKVW) and the Dutch National Safety Guidelines (NBR), accessible doors and windows must comply with burglar-resistance class 2. BUVA IsoStone thresholds can be used under burglar resistance class 2 façade elements, providing the fitter complies with a number of conditions. Noise insulation Requirements are set in the Dutch Building Code regarding the characteristic noise resistance of exterior partition constructions. Noise leaks by doors have great impact on this performance. In order to prevent noise leaks, doors can be sealed optimally

by using BUVA IsoStone thresholds and seals. Resistance to damp from outside (waterproof) and airtight A door in the exterior partition construction is the entrance to the residence. It is also a critical connection regarding airtightness and waterproofing. Thanks to the shape and design of BUVA IsoStone thresholds and the use of seals, doors can be sealed optimally with attention to airtight construction and the accompanying savings on the Energy Performance Coefficient (EPC). Energy saving With their low U-value, the BUVA IsoStone thresholds provide a reduction in the Energy Performance Coefficient (EPC). The excellent insulating thresholds prevent cold radiation. This means there is no unlimited heat loss to the outside. The Dutch Building Code sets requirements for new-build houses and radical renovations.
