Fire Regulations Determined the Insulation Choice for the Garage

PAROC CGL 20cy is cost-effective, easy to install, and visually appealing

Located on Näätäkuja in Western Herttoniemi, Helsinki, this newly built detached house replaces an aging post-war home that was carefully dismantled due to its poor condition. The area’s zoning regulations required the new structure to reflect the original in both its size and architectural style. While the exterior respects the historical context, the home has been thoughtfully designed to meet current building standards and the specific requirements of its owners, Piia Hammaren-Luoso and Mikko Luoso.

According to Mikko Luoso, every aspect of the construction project – from planning to material selection – was guided by the goal of creating a functional, healthy, and energy-efficient home. The main structure was built by using cellular clay blocks, and the intermediate floor of the garage was constructed with hollow-core concrete slabs to maximize the ceiling height in the basement.

However, the hollow-core slab alone did not meet the fire compartmentation requirements specified for garages. A solution had to be found, as the garage was a non-negotiable part of functional living for Luoso. “My car is always in the garage,” he adds.

Discovered through online research, PAROC CGL 20cy stood out immediately. It fulfilled the needed fire protection regulation, and also impressed with its cost-efficiency, clean appearance, and effortless installation.

Mikko Luoso is looking at the ready ceiling with PAROC CGL 20cy lamellas installed and painted.

Fire tested and ETA-approved system consists of PAROC CGL 20cy lamellas and PAROC SW glue (XPG 001) for installation.

“Fire regulations were the decisive factor, but PAROC CGL 20cy is also cost-effective, quick and easy to install, and even looks great,” Luoso says.

The garage is now complete, and, according to Luoso, the installation of the roof insulation went exactly as planned. “The installation was smooth and efficient. It only took a few hours, even in a spacious 28 m² garage.”

The ceiling was also painted with silicate paint, which Luoso happened to have in storage. The use of silicate paint, in combination with PAROC CGL 20cy, is permitted from a fire safety perspective, which was confirmed before painting.

Luoso and Hammaren-Luoso are very pleased with the result.

“The garage looks fantastic. The acoustics in the space also changed noticeably after the installation,” Luoso notes.

The brand-new garage will soon be in use. The Näätäkuja house has been under construction for two and a half years, and Luoso has been actively involved on-site, especially since retiring last summer. The project is now finally nearing completion, and the couple is eagerly anticipating moving into their dream home.

“We plan to live there for the rest of our lives,” Luoso says.
