ARE PERLITE INSULATING CONCRETE ROOF DECKS WORTH THE MONEY??

The resounding answer is yes!! Perlite Insulating Concrete Roof Deck Insulation offers the Architect, Contractor and Building Owner some major advantages not seen with other types of roof deck insulation.

It offers the Architect peace of mind by reassuring them that they have selected the most appropriate product for the project. Perlite Insulating Concrete offers many benefits over polyisocyanurate board insulation or glass fiber batt insulation.

Ø Perlite Insulating Concrete provides thermal mass to moderate thermal shock of roofing membranes. This greatly enhances long-term membrane performance. Weights are comparable.

Ø The system is not damaged by roof leaks and does not absorb and harbor water.

Ø The system is ideal for roofing over precast tees or Dycore panels. It provides custom slope-to-drain which is not affected by positive or negative camber of precast panels and will accommodate field dimension variations gracefully.

Ø Perlite Insulating Concrete greatly enhances indoor air quality by eliminating glass fiber insulation and reducing spray-applied fireproofing requirements in interstitial spaces and return air plenums. It also eliminates air infiltration through roof system by sealing corrugations in the metal deck.

Ø ConDeck Corporation's membership in the U.S. Green Building Council lets the Architect and Building Owner rest assured that their best interests are being protected and that the product choice is friendly to both indoor air quality and the environment.

Ø Perlite Insulating Concrete is a dual purpose product as it insulates and is integral to 31 U.L. fire-rated assemblies.

To the Contractor Perlite Insulating Concrete allows for project flexibility:

Ø It allows interior trades to start work immediately after installation by effectively drying-in the Project.

Ø The Contractor can schedule the roofer as time and weather permit. This greatly relieves coordination issues between the Contractor and the roofer, and allows the Contractor more scheduling flexibility.

To the Building Owner, the system offers long-term advantages:

Ø Perlite Insulating Concrete offers the Building Owner a permanent roof insulation system. R-value does not decrease with age.

Ø The system can be reroofed cost effectively. Old roofing can be torn-off without damaging insulating roof deck. There is no need to tear-off roof insulation, and there is less impact on the local landfill during reroofing operation.

Ø It is a “life-of-the-building” product.

To all of the building team members it offers unsurpassed economy, scheduling flexibility and long-term performance. You will be astounded at the cost savings! One way to add Perlite Insulating Concrete to your roof insulation specification section is as a Contractor's Option, by adding the following text:

"Contractor's Option: Contractor may use Perlite Concrete Roof Deck Insulation in lieu of the type specified and indicated. Install Perlite System in accordance with Perlite Institute Catalog 31-95."

This way the onus will be on the General Contractor to evaluate whether the system is viable and cost effective.

TAKE A LOOK FOR YOURSELF!

In July everyone was invited to "take a look." Many design professionals took us up on the offer. If you would like to see a perlite insulating concrete roof deck being installed, give us a call. We will be glad to make arrangements for you to see the job first hand. Come get some fresh air and see what a quality installation looks like. Touchy-Feely is really the best way to evaluate any building system. The more you know about how the system goes down, the better we look. All we ask is that proper construction site attire be worn and that the safety procedures of the General Contractor be abided by.

WHAT THE HECK IS ELASTIZELL ENGINEERED FILL?

Elastizell Engineered fill is lightweight Cellular Concrete which is ideal for engineered backfill, sliplined pipe projects or pipe abandonment projects.

Elastizell Fill is flowable and flows like water to fill nooks and crannies completely, but requires only one fourth the mix water of regular grout. Millions of tiny air bubbles explain its flowability and light weight. Elastizell will flow up to 800 feet in pipe abandoning or sliplined pipe applications.

ConDeck Corporation is the certified applicator for Elastizell products in New Mexico. Elastizell Engineered Fill is a perfect solution for engineering projects where site fill materials are not acceptable, where time and expense are an issue or where working quarters are tight and inaccessible to earth moving and compaction equipment. Being pumpable, staging areas are small; on-site storage is eliminated; and dust control is not an issue. Elastizell Engineered Fill is an excellent choice for conduit abandonment, slip-lined pipe applications and for emergency backfill situations. Unlike structural concrete, Elastizell is fully excavatable.
