Increase energy efficiency, Reduce energy bills, Prevent roof rot and Give your attic a long life

‘There is no place like home’ they say, and making your home a happy place is important. A house is turned into a home not just by the people living in it but the very infrastructure and its maintenance as well. With that comes the role of insulation, ventilation, and an overall renovation of the mere structure that adds on to it. Homes have different corners and spaces that need special attention. 

The attic is one of the most vital areas of a home. Being a bigger space, proper care for the attic needs is a must. It is used for several purposes. Some may have turned it into a working place and some into a bedroom or even as a storeroom. Attic insulation stabilizes the thermal condition but it also equally needs to be ventilated to function better.

Why Do You Need Attic Ventilation?

‘About 90% of homes have excess moisture that leads to roof and attic problems.’

 Have you ever experienced an unreasonable increase in the heat? This happens when your attic is inadequately and inappropriately insulated and ventilated. What do you, when the house gets hotter? The first thing would be turning on the air conditioner or fans to cool it down. This increases when it gets hotter. You tend to use the cooling systems more and with that, the bills go high. All such problems lead you to one of the solutions like good ventilation. 

Attic shields your house like a hat, keeping the air in or out varying with the weather and seasons. When your attic is not properly ventilated in summer, the heat migrates into the attic causing it to heat up. While in winter it becomes cold and allows more space for the heat to increase which increases moisture.  For a better understanding of the attic rafter vents, here is what you need to know:

Attic Ventilation during Summer Attic Ventilation during Winter
Attic ventilation helps to prevent the hot and moist air and rather balances the airflow from the outside in a uniform way.  Attic ventilation helps you get rid of the wet and hot air which causes serious damage like a broken roof or a mold problem.
It helps in eliminating the hot air in the attic with the radiant barrier between the attic space and roof structure.  It helps to keep the temperature even and prevents ice dams that can be damaging. 
Regulates proper air circulation in your home keeping the attic intact. Regulates proper airflow in your home keeping the attic intact.
Extends the durability of the shingles by keeping it cooler during summer.  Gives longer durability to your attic. 

What is Attic Rafter Ventilation?

Attics being the bigger part of your home require enough ventilation besides insulation. Attics need to be free from clogs to ensure maximum airflow. Due to the accumulation of debris, the vents become clogged. For this, there have to be certain measures taken and procedures to follow. Rafter vents are used to protect the opening (for airflow) in your attic. Attic rafter vents are also known as baffles. It ensures a clear soffit vent which enables the channel for the outside air to be transversed into the attic and flow out through the roof vents. These vents are usually placed in the attic ceiling between rafters that certainly meet the attic floor. Baffles or rafter vents play a vital role by creating a channel for air circulation from your soffit (underside edge of the roof) to the ridge (roof peak). An entire length of baffles of a rafter bay from the soffit to ridge vent can work the best for your attic.  With rafter vents or baffles, your attic floor can be covered with insulation where the floor connects the roof. 

Are Rafter Vents And Baffles Same?

You call it rafter vents or baffles, both are the same. Baffles are also known as venting chutes,  rafter vents and even wind baffles. Generally relating to the field of the roof and attic ventilation systems, this came to be referred to as baffle vents, venting channels or under-roof-deck vents or attic insulation vents. It all collectively came to be known as ‘Rafter Vent’ or ‘Rafter Ventilation’. 

What Are Rafter Vents Made Of?

Varying in their lengths, rafter vents are usually made of aluminium, sheet metal or plastic. Rafter vents or baffles are made from polyvinyl chloride, cardboard or rigid foam board and they can be stapled for installation. Rafter vents consist of waterproof foam and are commonly in pink, blue or tan in colour. 

Benefits Of Attic Rafter Ventilation

Proper Air Circulation

Attic rafter ventilation provides air circulation or airflow. It creates space in narrower gaps and direct fresh air from the soffit. So, there is a constant flow of fresh air through the soffit vents to the attic. This results in improved air circulation. 

Prevents Mold or Mildew

Moisture is an inevitable problem in most home spaces or any structure. Regardless of a well-sealed or covered roof, moisture is likely to accumulate in the attic. Attic rafter ventilation keeps the damp level low and prevents condensation that causes moisture. 

Prevents Ice Dams

During winter, ice dams on the roof become a problem as they meltdown and refreeze over the soffit. This can cause damage to the roof and eavestrough. Ventilating your attic with rafter vents can prevent the ice dams from forming. 

Reduction of Energy Bills

Good attic rafter ventilation reduces the energy system by improving the attic condition. This reduces energy bills automatically. 

Prolonged Attic Life 

Many homeowners notice and face difficulty in the durability and rafter vents play a vital role here. Including the shingles, attic rafter ventilation improves the level of comfort and quality of the attic. 

What Is The Ideal Way To Ventilate An Attic?

According to the studies,the attic ventilation system has to be balanced. It provides an equal  intake amount in net free area through soffit vents or ridge vents. The cool or dry air enters the attic and removes the hot and moist air from the inside.

Soffit Vents Installed in the soffit, allows airflow into the attic, ranges from 6 inch stainless steel vents covers and are placed between the rafters covering the length of the soffit. 
Ridge Vents Run the length of the ridge by replacing the shingles or even tiles, interior baffles that allow airflow on the outside and prevents rain from blowing in.
Turbine Vents Most commonly used vents, turned by even the slightest wind, draws oit air from the attic. 
Eyebrow Vents Eyebrow or turtle vents provide curved opening on slopes of the roofs, used in pairs to boost air movement.
