Frequently Asked Questions

What is the purpose of the Renovation, Repair, and Painting (RRP) Rule?

The purpose of the Renovation, Repair, and Painting (RRP) Rule is to minimize exposure from lead-based paint dust during renovation, repair, or painting activities. This is a key effort in reducing the prevalence of childhood lead poisoning, particularly lead poisoning caused by housing contaminated by renovation activities. This will also minimize exposure to older children and adults who are also adversely impacted by lead-based paint dust exposure. Lead paint was used in more than 38 million homes prior to its ban for residential use in 1978. This paint can form toxic dust when it is disturbed during normal home repair work. The EPA's Renovation, Repair and Painting (RRP) program is designed to reduce lead contamination by training contractors in relatively simple lead-safe work practices, and certifying contractors to make sure that they follow lead-safe work practices. We also want consumers to choose firms that are certified. Given that lead poisoning can cause a wide range of physical, intellectual, emotional, and behavioral issues with societal and financial impacts, this program is prevention-based, cost-effective, and a long-term bargain.

What do "R" and "U" value mean?

The R-value represents the resistance a material has to heat flow. R-Value measures the insulation properties of a material; the higher the R-value, the greater the resistance. Insulated glass provides a pocket of air to enhance its R-Value.

The U-Value is an insulation rating for transparent objects like glass. The term U-value is measured by the amount of heat that escapes a surface, like a wall, ceiling, or in our case, a window; the lower the U-Value, the better the insulation.

Will this window meet egress requirements?

All of our windows in some capacity will meet egress requirements based on size.

Will my new door meet ADA requirements?

Yes, based on hardware and size.

Can you replace just the glass in my existing window?


What are the benefits to having Low-E or argon filled glass?

The low-e coating, placed on the inside of the insulating glass unit, enables the sun's short-wave energy to enter the room and at the same time prevents internal warm air from leaving the room.

Will Low-E or argon gas filled glass change the way my window looks?

Yes, Low-E coating adds a slight tint to the glass. Argon has no appearance. We recommend they be used in conjunction with each other.

What are grids?

Grids, also referred to as mullions, are horizontal or vertical slats on, or in-between the glass. They simulate individual lites.

Why does any walk-through door or sidelite require safety glass?

According to 1977 Federal Glazing Standards, safety glazing materials must be used in any door or anything within 2 feet of a door. In addition, any glass that is within 18"of the floor must also be safety glass. This lessens the risk of injury should the glass break.

How does my insurance company get billed for the auto glass services?

Portland Glass® will process all of your insurance paperwork for you and direct bill your insurance company.

How long will the windshield replacement take?

A windshield replacement takes about 2 hours from start to finish. Due to the air bags and manufacturer requirements the car has to set for an hour after the installation to allow the adhesive to cure properly.

What happens to my State inspection sticker after the new windshield is installed?

If your current State inspection sticker is valid (not expired), it will be placed back on your new windshield. We are a State Sticker Replacement Station and have the authority to do this transfer. If your sticker is expired you will be given your expired sticker back with your paperwork.
