Find our Kensington HPP windows FAQ below. Here we’ll look at all of the common questions we get about Kensington HPP windows. If you have a question that isn’t answered we invite you to post a comment at the bottom to ask your question. We read all of the comments and will be happy to answer your question for everyone to see.

Is Kensington the same as Kensington HPP windows?

No. The old company called Kensington went out of business many years ago. Some of the management bought the assets out of bankruptcy, but they did not buy the liabilities. That means the old company called Kensington is gone and those old Kensington warranties are worthless.

The new company is called Kensington HPP and they very much want you to know that the two companies are different. Similar names, but different companies. Find reviews of Kensington and other window manufacturers here.

Are Kensington HPP windows any good?

Kensington HPP windows are perfectly fine but not particularly remarkable. The small manufacturers like this are inherently risky and I wouldn’t take the gamble of buying their products. This is made especially clear by the bankruptcy of the old company, Kensington. Everyone who bought Kensington windows was out of luck when they went out of business. All of those people now have no warranty.

Kensington HPP is a different company but the same risks remain. You can find similar windows from a more stable manufacturer and that’s what I would recommend.

Are Kensington HPP windows energy efficient?

Yes. Kensington HPP offers a range of efficiency options and they will generally offer choices that are as efficient as anything else you’ll see in the market. The most efficient product isn’t always the best choice as most customers will balance efficiency with cost to find a solution that makes sense for their project.

Why would anyone buy Kensington HPP windows?

I don’t know. The windows offered by Kensington HPP are perfectly nice, but I wouldn’t suggest taking the gamble on a small manufacturer like that. Especially since the last iteration of Kensington windows went bankrupt leaving all of their customers with no warranty.

I know the folks at Kensington HPP will be happy to tell you that they’re different and they’re super, but I just wouldn’t take the chance. You can find more replacement window reviews and info here.

Is the warranty on Kensington HPP windows any good?

The warranty from Kensington HPP is actually very strong. They have relatively few limitations. The screen frames are only covered for 1 year, the warranty is only transferable in the first 10 years and they do not cover labor for replacing any defective parts.

What does the HPP mean in Kensington HPP?

High Performance Products.

Will Kensington HPP honor Kensington window warranties?

No. The old company called Kensington is bankrupt and out of business. The new company, called Kensington HPP does have the ability to make replacement parts. Readers of the site have told us that Kensington HPP has made replacement parts for them for a cost.

It’s better to be able to get the parts, even if you need to pay for them, than to not be able to get them at all. If you have a problem with your older Kensington windows you should contact Kensington HPP to see if they can help you order replacement parts.

How long does it take to get Kensington HPP windows?

Kensington HPP windows are all custom made so it will take time to get your new windows. The exact time can vary based on the options you’ve picked and the demand at that time. We would expect orders to take 8-10 weeks to arrive after you’ve placed your order. You should check with with dealer on exact timing when you’re ready to place your order.

How much should Kensington HPP windows cost?

The windows are custom made so the pricing will depend in part on what you order. If you order more basic options the prices will be lower and if you order fancier options like the heat mirror glass the price will be higher. Find more info on 2022 replacement window prices here.

Does Kensington HPP use Heat Mirror glass?

Heat Mirror glass is an option in the Quantum 2 windows from Kensington HPP. In my opinion heat mirror isn’t really any better than regular triple pane glass so it’s a lot of sales pitch for little benefit. You’re likely to find a better value with a triple pane window.

Is Heat Mirror glass good?

In the past heat mirror glass had warranty issues, but they say that is now fixed and we don’t have any reason to believe otherwise. The efficiency ratings for heat mirror glass are generally similar to the ratings you’ll see on triple pane windows from many manufacturers. In my opinion heat mirror glass is not with the cost.

    I just had a demonstration yesterday where the rep used a heat lamp and BTU meter. He went through single pane, double pane, argon, insulation (!) between panes of glass and then the mirror technology. If this method is truly reliable, the mirror technology was impressive in blocking heat. We have west facing windows in New Hampshire so battle sun in the summer and cold in the winter. Do you know if this demonstration with the BTU meter is legit/accurate?

      Sure, it’s legit, but the results are very similar to what you’d see from any newer window design. They try to make things exciting and very qualitative so you think they’re the only people in town who offer this or that. Ever window will have efficiency ratings so you can compare more objectively. From what I’ve seen the ratings for heat mirror aren’t much different than the rantings for any triple pane window and the prices are often higher.

      Check out this video on the heat lamp demo. If you’re near Manchester we might be able to help with another option. Find recommended window companies all over the country here.
