Scope of Work includes:
1. Weather-striping 130 fire, mechanical, access and exterior doors. In many cases the existing door knobs hinder the effective operation of the weather-stripping when it is installed on the jamb so the weather-stripping is installed on the door. This eliminates knuckle scrapping.
- Examining surfaces affected by the installation of weather-stripping and notifing ESCO in writing if substrates are unsatisfactory
- Testing doors to be weather-stripped for proper closing and notifying ESCO in writing if any door hardware needs to be adjusted to ensure proper operation
- Removing any old weather-stripping and door sweeps
- Attaching new weather-strip DX 1000 with self tapping screws; consisting of an aluminum carrier with a clad foam insert (pproximate size 5.2m x 17’ long)
- Installing door sweep DSS 10914 consisting of long heavy duty aluminum extrusion, single line 13mm Finseal
- Installing weather-stripping/seals plumbing, squareing and leveling, wherever possible
2. Foaming pipe, duct and conduit penetrations at various locations throughout the building (i.e. mechanical rooms, attic, etc.)
- Differentiating eligible leakage areas through the thermal barrier from interior holes
- Examining sizes and conditions of voids to be sealed to establish correct thickness and installation of materials
- Verifying that the surfaces are ready to accept the work
- Applying sealants within manufacturer's specifications
- Including one-component and two component polyurethane foam materials
- Using single component foam for cracks and openings 6 mm to 50 mm wide
- Using two component foam sealant for gaps over 50 mm and voids in hidden cavities
