Buying Guide – How to Choose the Best Keyboard Foam
Choosing the right keyboard foam requires understanding materials, thickness, and compatibility with your specific layout and build style.
Material Type
The most common materials for keyboard foam are PORON, EVA, and cotton sponge. PORON is a high-density polyurethane foam known for its excellent sound absorption and durability. It is often preferred by enthusiasts for its ability to produce a solid thock sound. EVA foam is a closed-cell material that is softer and more affordable but may not dampen sound as effectively. Cotton sponges are softer and easier to cut but may compress over time.
Always prioritize high-density materials like PORON if you want the best acoustic performance and longevity.
Thickness and Size
Thickness usually ranges from 1mm to 3mm depending on the specific application. A standard bottom case foam is often 3mm to fill the gap between the PCB and case. Switch pads are typically thinner, around 0.5mm, to sit between the switch and PCB without affecting actuation. Always measure your internal case cavity to ensure the foam will fit without pressing on components.
Verify the dimensions of the sheet or pre-cut pieces before buying to avoid fitting issues.
Keyboard Layout Compatibility
Not all foam products fit every keyboard layout. Some kits are designed specifically for 60% keyboards, while others are universal sheets that you must cut yourself. Check if the product lists compatibility with your layout, such as 61, 64, 75, or TKL. Universal sheets offer more flexibility but require manual trimming to match your PCB holes.
Choose pre-cut kits for specific layouts or large sheets for custom builds.
Installation Method
Foam products come with or without adhesive backing. Adhesive foam is easier to install but can be harder to remove later. Non-adhesive foam is ideal if you plan to disassemble your keyboard frequently. Some kits include tools like pry bars to help with removal and installation. Consider your comfort with DIY modifications when deciding on an adhesive option.
Non-adhesive foam is generally safer for your components and allows for future adjustments.
Target Noise Source
Determine where the noise comes from before buying. Spacebar foam targets the hollow sound of the spacebar, while bottom foam addresses general case resonance. Switch pads reduce the clack of individual switches against the PCB. Using multiple layers often yields the best results. If your issue is just the spacebar, buy a specific kit; if it is general resonance, buy a large sheet.
Identify the source of the noise to buy the correct type of foam.
Color and Aesthetics
Foam comes in black or white colors. White foam is often preferred for aesthetics if you leave your keyboard open or have an RGB build where the foam might show. Black foam blends in better with dark PCBs. While this does not affect sound performance, it is a factor if you care about the visual presentation of your build.
Select a color that matches your keyboard's internal components or your personal preference.
Price and Value
Prices vary significantly between small spacebar kits and full-board PORON sheets. Basic EVA kits can be very affordable, while premium kits with multiple layers cost more. Consider the number of pieces included and the quality of material when calculating value. A slightly more expensive PORON sheet might offer better longevity and sound quality than a cheaper EVA option.
Compare the amount of material and its quality to ensure you are getting value for your budget.
Brand Reputation
Reputable brands like DUROCK or KBDiy often ensure consistent quality and precise cutouts. Unbranded or generic brands may have inconsistent foam density or cut dimensions. Check user reviews to see if others faced fit issues. A reliable brand often means better customer support and quality assurance. This is especially important for pre-cut kits where errors are hard to fix.
Look for products from established keyboard accessory manufacturers to avoid fit problems.
How to Use and Care for Your Keyboard Foam
To install bottom case foam, start by disassembling your keyboard carefully. Use a prying tool to open the case and remove the PCB. Clean the bottom of the case to ensure no dust or debris is left. Cut the foam to match the internal dimensions of the case, leaving a small gap around the edges. Place the foam in the bottom cavity and secure the PCB and case back together.
For switch pads, peel the adhesive backing from the foam sheet. Align the cutouts with your switch positions on the PCB. Press down gently to secure the foam in place. Make sure the foam does not block any RGB LEDs or interfere with the switch stems. Once aligned, reassemble your keyboard and test the typing sound.
Care for your foam by avoiding excessive heat or pressure that might deform it. If you need to replace the foam later, remove it gently to avoid damaging your PCB. Dust can accumulate on the foam surface; use a soft brush or compressed air to clean it. Proper installation ensures your foam lasts as long as your keyboard.
Frequently Asked Questions
Does keyboard foam actually make a difference in sound?
Yes, keyboard foam significantly reduces the hollow and echoey sounds associated with mechanical keyboards. By filling empty cavities, it absorbs sound waves and vibrations, resulting in a thicker and more solid typing sound. Many users report a noticeable improvement after installing dampening foam.
What is the best material for keyboard foam?
PORON is widely considered the best material for keyboard foam due to its high density and excellent sound absorption properties. It is durable and does not compress easily, maintaining its performance over time. EVA foam is a cheaper alternative but is generally softer and less effective at dampening.
Will foam affect my keyboard lighting?
Most keyboard foams are designed to sit between the PCB and the case, so they do not obstruct LEDs. However, if you use switch pads or spacebar foam, ensure you align them carefully. Some foams are translucent to avoid blocking light, so check the product details before installing.
How thick should my keyboard foam be?
For bottom case dampening, 3mm is the standard thickness. For switch pads, 0.5mm is typical to avoid interference with the switches. Always measure the gap in your specific keyboard case to choose the right thickness. Too much foam can prevent the keyboard from closing properly.
Can I use keyboard foam on a non-mechanical keyboard?
Keyboard foam is primarily designed for mechanical keyboards with internal cavities. Membrane keyboards do not usually have the same PCB structure to accommodate foam. However, if your membrane keyboard has a large gap between the top and bottom cases, you might be able to add thin foam to reduce noise.
Is it difficult to install keyboard foam?
Installing keyboard foam is relatively easy and requires only basic tools like scissors and a screwdriver. Most kits come with instructions and sometimes include prying tools to open the case. If you are comfortable taking your keyboard apart, you can install foam in under thirty minutes.
Can I reuse old keyboard foam?
Reusing old foam is possible but may not provide the same performance as new foam. Over time, foam can compress or collect dust which reduces its effectiveness. If the foam is still clean and springy, it can be reinstalled. Otherwise, it is better to replace it with new foam for consistent results.
Does foam work on all keyboard sizes?
Universal sheets of foam can be cut to fit almost any keyboard size. However, pre-cut kits are often specific to layouts like 60% or 65%. Always check the compatibility of the product with your keyboard layout. If you have a unique or custom keyboard, buying a large sheet is usually the safest bet.
