Window Weatherstrip Seal 5/16" Bulb Bubble Kerf Mount 4 Colors & 6 Length Options (25', White)

To reduce expenses and to help protect the environment, in early 2021 our household started taking a number of measures to cut our energy consumption. Those measures have proven successful: total 2021 electricity consumption in our single-family, detached home in the US SE was about 8,000 kWh (3,200 of which was for HVAC), compared to about 11,000 kWh annual average in previous years. [UPDATE on 1/1/23: our total electricity consumption in 2022 dropped even further to just 5,500 kWh (1,600 of which was for HVAC) for the year. We have HALVED our electricity consumption. Huge savings.]We are really happy with this weatherstrip seal. It was very easy to install and continues to be in great condition, having endured both very hot days and a cold winter.Here are some other products we purchased at Amazon that we can recommend to those interested in cutting home energy consumption:Aootek solar lights 120 LEDs with lights reflector, 270 degree Wide Angle, IP65 Waterproof, Security Lights for Front Door, Yard, Garage, Deck (4 pack): https://www.amazon.com/gp/product/B07NQ4L1SB , as well as Solar Lights Outdoor,WWimy 210 LED 2500LM Motion Sensor Lights with Remote Control, 3 Heads Security LED Flood Lights, IP65 Waterproof, 270° Wide Angle Illumination Wall Lights with 3 Modes (2 Packs): www.amazon.com/gp/product/B08T9F2MM1 Purchased in August 2021, these lights continue to work well here in the SE, saving us over 150 kWh/year.

It was thanks to this tool that we realized, for example, that our then uninsulated recessed lights were really problematic, prompting us to purchase the following.FF130E Recessed Light Cover: www.amazon.com/gp/product/B002XVPUAO If you have recessed lights and they’re not well insulated in the attic, energy wastage can be massive.

They allow us to monitor temperature and humidity in four places at once: outside, in our living room, in our crawlspace, and in our unfinished attic. Thanks to these readings, we have established a smarter, more energy-efficient way of ventilating our crawlspace. They also helped us see that our attic needed additional ventilation in the roof, prompting us to purchase the following.4 SEASONS Solar Powered Polycarbonate Vent, Weatherproof Design, Quietly Cools Up to 500 Sq Ft, 400 CFM: www.amazon.com/gp/product/B01DMSCPJARYB HOME Room Darkening Patio Door Curtain, Hanging Room Divider Screen Insulated Drapes Privacy Wall Panel: www.amazon.com/gp/product/B07D32DJ2V , as well as RYB HOME Blackout Curtains & Drapes - Total Privacy Thermal Efficiency Backdrop Curtains for Bedroom Room Divider Vertical Blind Living Room Patio Sliding Glass Door: www.amazon.com/gp/product/B077SZRBNJGrandekor Blackout Window Blinds and Shades Cordless Cellular Shades: www.amazon.com/gp/product/B07NWBGVL3

dust sticks to material, concerned about that, but maybe it is ok. this has no foam core, so is can squashed more, but provides less insolation. It will block air flow, but not so much radiant heat.

Worked great.

it is the cat's meow. worked great.

Perfect fit for I r the seals around my casement windows. Old ones were cracked and dried out. Like new again.

awesome

I purchased this to replace the weatherstripping for a Pella Proline sliding glass patio door. When a new door was installed, the old weatherstripping tore, and there was damage to the threshold. This seemed at 5/16 like it would be a decent replacement as measured for a little under a 5/16 inch gap.First, 5/16 is the max outside diameter, and the outer bulb material is extremely thin (maybe 1/32). After assessing the door damage, I decided to go with a different bottom weatherstripping, and use this to replace some of the damaged weatherstrip on the sides. In order to reinforce, I was thinking of stuffing the bulb with 1/4 inch caulk backing. Unfortunately, that would have taken 2 weeks to order and arrive (stores don't carry). Instead, I cut some of the bulbing, rolled over, and placed inside the other. That seemed to work good for the sides.So, in summary, I would advise you know your needs. If the gap is 1/4 inch or less (noi more), and needs compression flexibility, this will work fine. If you need something a bit more rigid, or a gap larger than 1/4 inch, you may want to look for something else.Pros: Seems good quality, kerfs are decent, pliable enough to cut and transition in with other weatherstrip, would be okay for anything compressing 1/4 inch or less.Cons: Very thin bulbing, not good for anything over 1/4 inch (in my opinion), may not be good for harsher weather conditions, needs internal reinforcement if the gap is even slightly over 1/4 inch.

This product was the perfect fit for my windows from 1992!
