ISO BLOCO 600 / ISO BLOCO ONE sealing tapes / ISO-ZELL PE-CORD backing rods
ISO-CHEMIE's foam sealing tapes are providing a high-performance, weather-resistant, airtight sealing solution around new timber frame sash windows installed on a Victorian terrace extension project, whilst also delivering improved thermal efficiency.
ISO BLOCO 600 and ISO BLOCO ONE sealing tapes, together with several ISO-ZELL PE-CORD backing rods, were specified by John Potter Architect Ltd to secure an airtight seal between the window and door sets and the dressed sandstone external wall construction.
The windows, installed within a timber frame inner leaf behind a sandstone outer leaf, feature rebated apertures designed to provide additional protection against wind-driven rain.
The self-adhesive tapes have been applied to the cills, outer face of the windows, heads and jambs of the windows, while the cord has been located between the extension windows and the surrounding rebates to provide a backing strip for additional silicone sealant.
A spokesperson for John Potter Architect said: “We selected ISO-CHEMIE’s products for their ease of use, their high quality, and for their anticipated delivery of long-term protection from the elements. The delivery of the product direct to the contractor, on site, was an added attraction in choosing ISO-CHEMIE’s products.”
Up to 70% cost savings can be achieved using ISO-CHEMIE’s tapes, which enable installers to seal windows from inside the building and avoiding the need to use time-consuming and costly scaffolding and ladders among other external access systems.
