EXTERIOR WALL CLADDING

EXTERIOR INSULATION AND FINISH SYSTEM (EIFS)


HUFFMAN INSPECTION SERVICES (H.I.S.) Is certified as an EIFS inspector by the Association of the Wall and Cieling Industry (AWCI).

AWCI trains, tracks and ensures that everyone with this certification has documented experience and education to properly perform and execute all  inspections to the highest industry standards. 

AWCI requires passing a comprehensive exam related to the installation of EIFS over various substrates and conditions, but also requires and assures that the reporting content and procedures required by the industry are understood, practiced and meet those requirements during every inspection.

H.I.S. has experience as a certified inspector with all EIFS manufacturers products and installation requirements. Dryvit, STO and Parex have all been inspected by HUFFMAN INSPECTION SERVICES. 

Due to the complex nature of different installation methods and materials over different substrates, including flashing components and pre-EIFS components for treating rough openings and wall penetrations, a full-time QA observer / inspector is highly recommended for a successful installation, which results in a "Moisture Free Environment®" in the building interior.

Certain manufacturer's require 3rd party inspections for warranty purposes. Those 3rd party inspections assure the manufacturer that the products were installed as required by the manufacturer and all project related construction documents.

HUFFMAN INSPECTION SERVICES has performed several EIFS inspections throughout Nevada and California over the past twenty years. Hospitals, schools, airports, casinos, big box home improvement stores, and other public and private structures without any call-backs. H.I.S.Has also performed forensic evaluation of EIFS for several major casinos in the Las Vegas area. Due to the hot/desert region in Las Vegas, nevada, EIFS is a popular wall cladding due to the insulation capabilities as well as the ability for the EIFS system as a whole to handle the extreme thermal movement which comes in a freeze/thaw type region/climate.
  There are commercial EIFS systems which have a primary drainage system incorporated behind the system, incorporating drainage mat, vertical adhesive for the installation of the EPS insulation boards, etc. Others also have secondary water/air barrier installed over the exterior sheathing prior to the EIFS system. It is important to have the secondary air and water barrier installation monitored to ensure it's continuity throughout the exterior of the buildiing, prior to the EIFS system installation.
The secondary air and water barrier will also treat the rough openings and wall penetrations as additional assurance of protection from water intrusion into the building interior from these highly attribitubles areas. Typically, a testing firm will be responsible for testing and providing isoated, chambered testing on walls and windows for air/moisture leakage after the air/water barrier installation is completed. H.I.S. does not provide these testing services.
It is recommended and sometimes required for the General Contractor to water-test a percentage of windows after the installation of the EIFS and related perimeter sealant at rough wall openings for windows, vents, etc. has been installed and cured minimum 48 hours.The water-test verifies the windows and related sealants are water-tight and performing as intended and designed or verifies water intrusion into the building interior as a result of failure of one or more of the components..
If there is water intrusion during window/sealant joint testing,measures are taken to identify he source(s) perform repairs and continue water-testing until there are no leaks or evidence of water intrusion into the building interior, prior to occupancy of the building.

These test(s) are monitored by the inspector so testing results are verified, witnessed and documented for the owner, general contractor and manufacturer for future reference. 


CEMENT PLASTER

HUFFMAN INSPECTION SERVICES several years experience inspecting the installation of cement plaster and related components on commercial and residential projects throughout California and Nevada.

A properly designed system has incorporated properly designed flashings and intricate components detailed and installed in conjunction with the cement plaster installation. The design and proper installation of flexible, self-adhering and/or rigid metal flashings are critical to a successful and complete water-tight installation. The actual application of the cement plaster is performed after extensive pre-plaster installation components have been installed.

Flashings for rough window and door openings, wall penetrations, wall transitions from one material to another, placement of control and expansion joints, handrail and balcony attachment points and details are all critical components in the system, which is why full-time quality assurance should be provided during the installation.

Cement plaster all looks the same from the exterior, it's whats beneath the plaster which seperates the performance of a typical installation from a very well designed,"Moisture Free" long lasting and trouble free cement plaster system.


A pre-stucco or "Lath" inspection is usually performed by a representative of the local building department.
Typically the building department inspector is checking for placement and spacing of lath fasteners, lath laps and other easily identified spacing and lapping requirements. The building departments may hire an independant consultant to perform this work or may have an inspector with qualifications in areas other than exterior wall cladding systems and waterproofing perform the inspection due to staffing difficulties related to the recent economy. The building department holds no liability for overlooking or missing something during the inspection which could be detrimental to the water-tight integrity of the system, which is why a 3rd party, full-time inspector is recommended.

The lath inspection by the building department is usually performed after all penetrations and rough openings have been flashed, all metal/ flexible saddles, counter-flashings, penetrations flashings and other critical components have already been installed are not in plain view of the inspector, therefore not always inspected to ensure conformance to the construction documents.

Inspection of all components and verfiying conformance with the construction documents during the installation and is critical for a successful and water-tight "Moisture Free Environment®" installation.

HUFFMAN INSPECTION SERVICES offers full-time Quality Assurance inspections for EIFS and cement plaster installations on commercial projects. We provide the same service in the field that the "consulting" firms employees: field techs/inspectors/monitors/consultants provide, although we charge less in most cases, yet provide the same thorough inspections, daily reports with photos, etc. as necessary to ensure all work and materials conform to the requirements of the construction documents. H.I.S. also tracks all items which are considered "Non-conformance issues" until they are verified as conforming, signed off by H.I.S. or other responsible parties, such as the Architect, Engineer, I.O.R., City, County, etc...
