The "V" Factor

The "V" Factor

The “V” Factor: What You Need to Know About Ventilation in New Construction.
Ceiling Air Vent
Ventilation is becoming an important topic in the world of energy efficient homebuilding (sometimes referred to as the “V” Factor). With the increase in green building and the tighter building envelopes that result, a new problem has emerged for builders. New buildings that are increasingly airtight can have poor indoor air quality.

Why the increase in air quality problems?
Older homes weren’t built as tightly as today’s standards and were ventilated by the wind or natural air leakage. Let’s not forget that some older homes had no insulation or insulation made of natural materials. These older products did not include volatile organic compounds (VOCs), flame retardants or other additives commonly found in building products today, so ventilation wasn’t as much of an issue.

Today roughly 25 million Americans suffer from asthma. The idea of an “airtight” house  – which might be energy efficient – may not provide proper ventilation ensure their health.

Today’s tight building envelopes require controlled mechanical ventilation to maintain optimal air quality. And it’s a part of energy efficiency that can be overlooked.

Which type of ventilation is best? There are a number of factors that ultimately influence which system is most appropriate. These include code requirements, the size of the building, combustion appliance type, and budget. Four common ventilation system options are especially suited to energy efficient homebuilding:

  • Exhaust Only — This common method uses a small exhaust fan placed in a kitchen or bathroom, which runs continuously or intermittently to exhaust stale air and moisture. These systems are inexpensive and easy to install.
  • Supply Only — In supply only ventilation systems, a fan brings in fresh air and stale air escapes through cracks and air-leakage sites in the home. These systems can include a filter to trap pollen and dust or a dehumidifier to control indoor humidity levels.
  • Balanced — A balanced system provides a much better ventilation solution because it includes separate fans that drive both inlet and exhaust air flow, which allows control of where the fresh air comes from and where it is delivered. Typical systems are designed to ventilate living rooms and bedrooms where people spend most of their time.
  • Balanced with Heat Recovery — These systems co-locate the usually separate fresh air and exhaust fans and an air-to-air heat exchanger so that the outgoing house air will precondition the incoming outdoor air. This system is ideal for colder climates.

Confined Space Guidelines

Confined Space Guidelines

OSHA's Permit-Required Confined Space Guidelines

Confined Space
As a partner in your success, we want to share the latest Confined Spaces Guidelines from OSHA. You can find the complete publication here.

Residential and commercial builders, remodeling contractors, home inspectors, sales representatives, and estimating contractors are all effected by these new guidelines so be sure to share this with your entire team.

First things first, what is a Confined Space?

A confined space is a space that…
  • Is large enough for a person to enter and work
  • Has limited or restricted means of entry and exit
  • Is not designed for continuous occupancy

OSHA defines a permit-required confined space as a space that has at least one of the following characteristics:
  • Contains or has the potential to contain a hazardous atmosphere
  • Contains a material that has the potential to engulf an entrant
  • Has an internal configuration such that an entrant could be trapped or asphyxiated
  • Contains any other recognized serious safety and health hazard

Hazards associated with confined spaces include:
  • Slips, Trips, & Falls
  • Electrical equipment and wiring
  • Flammable materials or chemicals
  • Health hazards (i.e. Dust, Mold, Rodents)
  • Mechanical equipment
  • Hot surfaces
  • Combustible materials
  • Utility Lines (i.e. Gas)
  • Structural Collapse
  • Additional Concerns
  • Noise
    • Amplified due to acoustics of the space
    • Damages hearing and affects communication
  • Slippery or wet surfaces
    • Increased risk of falls and electrical shock
  • Personal protective equipment
    • More common PPE such as hard hat, hard-toed boots, safety glasses, face shield, gloves, and overalls must be worn when needed

If a hazardous atmosphere is detected while a worker is in the confined space:
  • All activities should stop
  • The worker(s) should exit immediately
  • The hazard should be evaluated
  • Protective measures should be taken   

Always remember:   
  • Test the atmosphere prior to entry and periodically
  • Never enter a confined space if the atmospheric conditions are not suitable
  • Ensure an attendant is outside the confined space at all times
  • Follow your company’s confined space permit

Prevent delays and keep your job site safe by:
  • Identifying Confined Spaces in advance
  • Identifying all hazards in the space
  • Controlling all hazards in the space
  • Educating and training employees
  • Avoiding creating permit required spaces
  • Staying current as the rules change
  • Staying on top of your program
  • Communicating with GC and Subs

Crawl Space Insulation in Baltimore, MD

Crawl Space Insulation in Baltimore, MD

Crawl Space
Crawl spaces may be useful for out-of-sight storage, but they also come with a lot of inconveniences that leave many homeowners grumbling. At DeVere Insulation, our insulation experts want nothing more than to help you achieve maximum use of your crawl space, which is why we offer a variety of insulation services to suit your needs. Our insulation experts have the knowledge and skills to handle the most difficult of crawl space challenges, so you can depend on us for the very best results.

Common crawl space complaints
While every crawl space comes with its own unique challenges, some of the most common crawl space complaints include:
  • Dampness
    Since crawl spaces have direct contact with the soil beneath your home, it’s no wonder that dampness is a problem. The humidity in the soil can help harbor mold while creating an ideal environment for unwanted pests. No matter how isolated your crawl space is, the natural flow of air will bring the moist air and everything in it into the living areas.
  • Cold floors
    Another major complaint about crawl spaces is that they make the floors cold, a problem which is obviously more apparent during the colder months. Hot air naturally rises, leaving the coldest air beneath the house. Without proper crawl space insulation, all of that cold air adversely affects the temperatures of your floor, making the main level of your home needlessly uncomfortable.

Benefits of air sealing and insulating your crawl space

The only way to eliminate the headaches of your crawl space is to properly seal and insulate the area. Air sealing and insulating will:
  • Make your home more comfortable
  • Promote a healthier living environment
  • Decrease your energy costs

Attic Insulation
Attics are important for energy efficiency – 70% of energy loss happens through a poorly insulated attic. Energy efficiency is about more than insulation. An efficient attic includes air sealing. According to the Department of Energy, having your home air sealed by a qualified contractor can save up to 20% on heating & cooling costs.

To upgrade insulation in existing homes, loose fill insulation is blown over existing insulation using one of the following products:

Both applications add R-value to existing insulation and create a fresh new blanket of energy-saving protection.

Have a newer home and don’t think your home needs more insulation? It probably does. As building codes increase, nearly all homes need more insulation to ensure they are meeting current standards.   

Upgrading insulation is just one part of increasing attic efficiency. Air sealing prevents airflow between a home and the attic, keeping heated and cooled air inside the home by closing the gaps that leak air. Beyond leaks that can be easily spotted, your home may have many other holes in its envelope that can’t be easily seen. These air leaks are found around light boxes, plumbing stacks, soffit drops, basement box sills and more.

Spray Foam Insulation

Spray Foam Insulation

Spray Foam Insulation Spray Foam Insulation is the right choice for any application!

If you’re not familiar with spray foam insulation, think of a foam coffee cup or a foam ice chest. Both products keep heat or cold in, while protecting the exterior from transferring temperature. Spray foam insulation does exactly the same thing.

Spray foam insulation doesn’t just insulate your home like fiberglass, cellulose or other insulation products – it also seals air leaks. Why does this matter? Air sealing prevents air from inside your home from escaping through the cracks and crevices in your home. These exist around recessed (can) lights, plumbing stacks, electrical wires, attic hatches or doors, around chimneys or flues, and duct chases. This means conditioned air you’ve already paid for stays in your home.

There are two types of spray foam insulation: open cell spray foam and closed cell spray foam. 

Open Cell Spray Foam
Open cell spray foam insulation works as an insulator and air barrier. The typical R value of open cell foam is 3.7 per inch. Other features of open cell spray foam insulation are:

  • it is vapor permeable
  • is able to accommodate seasonal movement
  • is not a food source for mold
  • dampens sound

Closed Cell Spray Foam

As with open cell spray foam insulation, closed cell spray foam works as an insulator and air barrier. An additional feature of closed cell spray foam is that it is solid. The cells of the bubbles remain intact (closed), which makes the product rigid. The closed cell composition and increased density contributes to a higher R-value than that of open cell foam. This can contribute to building stability during storms and high winds.
