Why Office Insulation is Important - Lower Bills and Employee Comfort

June 23, 2016

Office or home, good insulation is the key to occupant comfort and energy efficiency. In North America it's even more relevant, because summer and winter temperatures vary so widely. For employees in an office environment comfort is a must - warm and comfortable in winter - cool and comfortable in summer. For building owners and managers, good insulation means efficient energy consumption, little energy waste, and measurable annual savings. Office environments are particularly susceptible to energy loss (heating and cooling). It's because there are so many potential weak spots, like suspended ceiling systems for example. That's why finding viable remedies is vital to ensuring energy efficiency and employee comfort. But finding solutions is a complex endeavour in offices, mainly because there are so many dynamics. Here, it would be advantageous to have a professional assess the overall situation. Professional insulation contractors have the resources and expertise to properly assess an office environment and the associated "building envelope". In fact, accurate assessment has important benefits: first, specific weak points are identified; second, remedies and fixes are proposed; and third, products and installations are recommended. The idea, of course, is to recommend retrofit and install options that will deliver the maximum return-on-investment. Heat loss through windows, ceilings, and walls is of major concern in any office environment. But with the right remedy, energy efficiency can be enhanced, and energy consumption can be better managed. It's all about which insulation approach (product and installation) will deliver the best overall outcomes. And here again, it's the professional insulation contractor who can advise on solutions that address air leakage, moisture issues, and proper ventilation. There's no substitute for a professional approach to building insulation. The experts understand how various types of insulation products work, how to properly install, and which combination of fixes will suit the energy issues at hand. An amateur approach, or installations that cut corners to save money, will set the stage for poor outcomes. And unfortunately, a re-work or re-install down the line will only serve to add extra project dollars (and time) to the efforts. For the professionals at Great Northern Insulation, a properly insulated office focuses on effective sealing, high performance insulation, and efficient ventilation. The GNI team does it all from start to finish - from assessment, to retrofitting, to installation. The result: better energy efficiencies, improved indoor comfort, and ongoing savings on utilities. GNI also promises complete customer satisfaction, providing manufacturer's warranties on everything installed. For the building owner (or manager) effective insulation can dramatically affect the bottom line. Because the building envelope performs with greater efficiency, the entire HVAC system operates in better balance. Fuel consumption is moderated, and operational maintenance is much reduced because the system isn't over worked. As well, indoor temperatures maintain consistency from season to season, further providing comfort to occupants (and employees). Great Northern Insulation can provide the recipe for better energy usage and quantifiable savings throughout the year. It's work that ensures a very reasonable "pay back" period for the building owner, making the project investment well worthwhile.

Foam Masters

Do it right the first time
- with foam mastersTM

January, 2021 regulatory phaseout of hydrofluorocarbons (HFCs) with the introduction of WALLTITE CM01. Using hydrofluorolefins (HFOs) with lower global warming potential (GWP) compared to HFCs, WALLTITE CM01 is the next generation of spray foam insulation.



Heatlok® Soya HFOTM leverages Honeywell’s latest Solstice® Liquid Blowing Agent technology. This new hydrofluoroolefin (HFO) blowing agent is the most environmentally conscious blowing agent produced to date, with a zero ozone depletion potential (ODP) and a global warming potential (GWP) of 1, which is more than two orders of magnitude (99.9%) lower than HFCs used in this industry.
