Metal construction sealing covered with new
ISO-Chemie iso-Metal Building Sealing System

Leading impregnated foam sealant specialists
ISO-Chemie has introduced a new easy-to-
install system for the high performance
sealing of light metal constructions in
accordance with energy saving regulations.

The iso-Metal Building Sealing System
conforms to EnEV regulations and complies
with guidelines laid down by the industrial
association for metal building constructions
(IFBS) for joint tightness on lightweight steel constructions.

The system is based around the European RAL principles of three level sealing
- the inside seals are more airtight than the external ones, allowing any trapped
moisture behind the joint, or within the wall, to escape outwards rather than
into the building.

The external seal provides weather resistance and breathability, while the
intermediate seal provides extra thermal and acoustic properties and the
internal one air tightness and humidity regulation. All three levels are
designed to accommodate movement between the adjacent materials.

The coordinated tapes featured in the iso-Metal Building Sealing System
provide quick and effective ‘fit and forget’ perimeter seals for both weather
and air tightness, while still remaining permeable to trapped water and
water vapour – similar to a flexible breathable style material.

The range includes ISO-MEMBRA SX which seals moving joints with large
tolerances on metal sheeting, timber, blockhouse, solid and prefabricated
buildings and façade insulation systems. It can also be used to seal window
connection joints in old and new build structures. Functioning like a membrane
seal for joints up to 18 mm, it provides improved protection against driving
rain while allowing trapped humidity to escape, avoiding damage caused
by condensation.

The range also includes self adhesive, fine pored ISO-PROFIL filler strips
for sealing and insulating trapezoidal and wave profile sheets used for roofing
and facades. These offer improved air circulation and thermal control in
building constructions and a class B1 material construction offers improved
fire resistance qualities.

The ISO-BLOCO 600 is a premier option for protecting joints – in buildings
up to 100 m high - against driving rain to a minimum of 600 Pa. It possesses
excellent thermal and acoustic insulation properties and can be used for
sealing skylights, cladding panels and curtain walling among other applications.
Other products include ISO-ZELL thermal tapes, which offer high compression
resistance and thermal insulation qualities, and the self adhesive ISO-BUTYL
for protecting overlapping joints. ISO-ACOUSTIC is also available for
improved sound absorption in trapezoidal sheet metal, sandwich and composite
constructions.

The iso-Metal Building Sealing System is compatible with all standard building
materials and comes with a 10 year warranty. It complies with the relevant UK
Building Regulations, as well as DIN EN standards, covering thermal conductivity,
dimension tolerance, impermeamability to driving rain on joints among others.

ISO-Chemie is one of Europe’s main producers of impregnated foam sealants,
specialising in the manufacturer of foam products from polyethylene (EPE),
polypropylene (EPP) and polyurethane (PUR) using the latest production techniques.

The company’s UK technical and distribution operation is based in the North
East of England, supported by a dedicated logistics service to ensure customer
orders are completed as quickly and efficiently as possible (usually next-day delivery).
