What is R value in insulation?
What is Insulation R-Value? R-value measures how well certain building insulation materials, such as foam insulation, can resist heat. The higher the R-value, the greater the performance of the insulation. Keep in mind that if insulation is compressed, the R-value will decrease.
What is the most common type of insulation?
The most common types of insulation are fibreglass, cellulose and foam. These types of insulation are available in a number of different forms depending on the location and R-value you intend to add.
What tools are needed to install insulation?
The basic tools needed for an insulation project are: a tape measure, utility knife, straight edge, lightweight stapler, or hammer tacker to secure insulation in place, and a putty knife. Additional materials may include a drywall compound and expanding foam sealer.
What is the best insulation for a door?
Spray Foam. Latex or polyurethane spray foam insulation can be used to fill small gaps and cracks and is ideal for sealing around doors, windows and vents. It sets quickly, and can be trimmed, painted or stained. Special equipment may be needed to apply foam to larger areas.
What to wear when working with insulation?
Working with insulation can cause itching and skin irritation, so make sure you take proper safety precautions: Wear long sleeves and pants, work gloves, safety glasses, and a dust mask or respirator to avoid irritating your skin or breathing in harmful substances.
Where to put insulation?

How to control heat loss?
Window Insulation. Another way to control heat loss is by improving the quality of your windows. Low emissivity (or Low-E) windows do not allow as much heat to pass through, keeping your house cooler when it’s hot and warmer when it’s cold. Shrink film and weatherstripping are low-cost alternatives.
