Repair professionals require a number of specifications for the mounting foam used to seal the gaps between the door or window frame and the building wall. They are concerned with the product’s secondary expansion, its elastic force, elasticity, coefficient of thermal conductivity, rate of cure and, of course, the product’s yield. Fome Flex 7 DOORS & WINDOWS ELASTIC PISTOL FOAM, a single-component polyurethane installation that combines the best of all these features. It is a unique product for professional sealing of windows and doors and provides the best thermal and acoustic insulation.
The market offers a wide range of options for window and door sealing professionals looking for a modern, high-quality, and reliable product for their work. However, Fome Flex 7 DOORS & WINDOWS ELASTIC PISTOL FOAM, a single-component polyurethane installation foam, outperforms its competitors in every respect.
Key Benefits: Flexibility, Thermal Insulation, and Movement Tolerance
In particular, the product’s permanent flexibility and lowest thermal conductivity of just 0.030W/mK ensure sustainability and excellent thermal insulation. In addition, the foam seam can withstand up to 25% displacement, making the product perfect for moving structures.
Fome Flex 7 DOORS & WINDOWS ELASTIC PISTOL FOAM also has a high Noise Reduction Index, which reduces the sound level to 63 dB. This figure is one of the best in the market. Regular foam reduces the sound level to 58–60 dB.
Low Secondary Expansion and Fast Curing Time for Efficient Installation
This foam also has a particularly low secondary expansion without the need for force to be applied to window and door frames. Certified product testing protocols confirm this. Note that the product also polymerises very quickly. The foam can be cut in as little as 25 minutes without damaging its structure and maintaining the best seam properties. This uniqueness of the Fome Flex 7 DOORS & WINDOWS ELASTIC PISTOL FOAM considerably speeds up and simplifies the craftsman’s work.
The product seals windows and doors without being weather-dependent. With an ambient temperature range of -5°C to +35°C, it works in rain or snow, so work doesn’t have to stop even in the coldest months.
These advantages are not the only relevant ones. With the rapid rise in the cost of building materials, many people are looking for a product with the highest possible yield. And the Fome Flex has a great one. The yield of this installation foam allows you to produce up to 40 metres of seams per bottle, enough for 7 standard doors.
Fome Flex 7 DOORS & WINDOWS ELASTIC PISTOL FOAM is an environmentally friendly product that is completely harmless to human health. It meets the requirements of the A+ French VOC Regulation and the Emicode EC1 Plus certificates.
Easy Application Instructions for Professional Results
The product is standardized and easy to use with numerous benefits:
- Vigorously shake the foam canister for 30 seconds before use.
- Firmly attach the application gun to the canister until it clicks.
- Clean the work surface thoroughly and dampen with water spray.
- Invert the canister completely (valve pointing downward).
- Fine-tune foam flow by adjusting the precision valve at the gun handle.
- Apply foam evenly, filling the cavity from bottom to top.
Tips for Optimal Performance in Various Conditions
- Cold weather application: pre-warm canister to +18°C by storing indoors or submerging in warm water for 15 minutes.
- For immediate cleanup: use Fome Flex Foam Cleaner on fresh, uncured foam residue.
- For cured foam: remove using Fome Flex Hardened Foam Cleaner or carefully using mechanical tools without damaging surrounding surfaces.
- Store unused portions upright in cool, dry conditions for maximum shelf life.
Frequently Asked Questions
While the foam can be cut after just 25 minutes, complete curing depends on environmental conditions, typically 12-24 hours for full hardening.
While specifically formulated for window and door installations, it can also be effectively used for sealing various gaps and insulating pipe penetrations in construction.
No primer is required. Simply ensure surfaces are clean and slightly dampened with water before application (no dampening needed when temperature is below 0°C.
The foam works optimally between -5°C and +35°C. Lower temperatures slow curing time while higher temperatures may accelerate it.
Fome Flex 7 DOORS & WINDOWS features minimal secondary expansion (about 30%) compared to standard foams, making it ideal for precision installations without frame distortion.
