Brand Name Spray Foam Products Deliver the Goods

December 09, 2014

Spray foam insulation (also known in the business as polyurethane foam insulation) achieves better energy efficiency and year-round comfort than any other insulation product on the market.Large project or small, new construction or renovation, spray foam can be installed in practically any part of the home:basement; ceiling (cathedral or sloped); crawl space; attic; even inside the walls. And best of all, annual energy savings are significant and noticeable!

WALLTITE ECO� is a respected and recognized spray foam product.It meets and/or exceeds industry standards across the country.It exceeds requirements of the National Building Code and meets the technical testing standards of the Canadian Construction Materials Centre.It's a multi-functional product that meets BOTH air barrier and insulation requirements for non-residential and residential buildings.It's a superior product that has successfully proven itself.

The WALLTITE ECO� brand adheres to virtually any surface - smooth, rough or uneven.When properly applied, it's 100% seamless, and provides the very best air barrier system for new construction as well as retrofits.As a combination air-vapor barrier, it's an application that suits residential, commercial, and institutional buildings alike.And for long-term performance, there's really nothing that compares with the product benefits and the energy savings.

WALLTITE ECO� is also considered to be environmentally friendly.It is widely acknowledged as a green product, and carries the EcoLogo� certification, which includes "aggressive rates of recycled content and the promotion of products that conserve resources".For the consumer who is discriminating, this is the ideal spray foam product, and comes with the assurance that the product is credible as advertised, and is "better for the environment".

An outstanding insulation contractor will install outstanding insulation products - products like WALLTITE ECO�.They will be expert in working with the product and with the installation. And the install teams will have the proper training; will be safety-oriented; and will be sensitive to the safety and security of occupants during an install.Above all, they will be experienced and qualified enough to answer any and all questions to the satisfaction of the customer.

Performing a professional spray foam installation cannot be overemphasized.The installation equipment is very specialized and sophisticated, and the application requires previous training and experience. Quite simply, this is not the right time for a do-it-yourself project.Indeed, with the complexities of an install, the failure risk is just too high for an unqualified installer.The professional knows how to properly install so that the product performs to its peak potential.

Like most professional projects, its best to do the job right the first time.This is especially true with a product like WALLTITE ECO�.The manufacturer's brand specifications are designed to provide guidelines that will deliver optimum performance from a premium product.And doing it right the first time achieves results.The short-term advantages include energy efficiency through an effective air-barrier, vapor barrier, and insulator, and the long-term benefits include significant cost savings and a reasonable "pay-back" period on the initial project cost.
