The efficiency of foam silicone profiles got a shining stamp of approval in a client test, where their foam silicone insulated front doors received CE certification with the best possible scores: Their doors were graded according to standards with a top grade of 9 for water resistance, and a top grade of 4 in air-tightness. But what is foam silicone, and why should you consider it for yourself?
The structure and properties
What makes foam silicone different from our other profiles is its “spongy”, closed cell silicone structure, that works almost like a foam mattress; it’s thick and sturdy, and holds its shape well, making it especially great for example insulating corners, where it provides support and keeps out the cold air and outside noise. Our foam silicone comes quite often as a co-extruded structure with two different grades of hardness, the soft, flexible round and insulating part, and the harder “spine” that settles into the groove and makes installation easy while keeping the seal from stretching. We can also provide threaded foam silicone, which absolutely prevents the silicone from stretching.
The properties of foam silicone aren’t too different from our other profiles, but there are some areas where it excels. Noise penetrates better than air, it will slip through even the smallest of cracks, but foam silicone has exceptional noise-canceling properties. For example, proofing your front door or balcony doors with foam silicone can notably muffle outside noise, something that people living in big city apartments are all too familiar with. We recommend installing the foam silicone on the warmer doorcase side, instead of the leaf, for best results.
Positive client feedback
A comment from one of our clients reported some very positive findings when they tried out our foam silicone on their front door:
Based on the client’s thermal camera images, they found that changing a regular pipe seal to a foam silicone seal raised the seal’s surface temperature by six degrees Celsius. The thermal camera image also showed a visible surface temperature difference on the door frame near the threshold that was proofed with pipe seal versus near the sides and top that were sealed with foam silicone.
Foam silicone is still criminally unrecognized, even when it has the potential to be a real game-changer for insulation, as well as for noise-canceling in big cities and homes near highways. If we have piqued your interest, feel free to contact our sales team to find out if foam silicone profiles are the best option for your needs.
