Why Freres builds on SPEC
“We are very excited to be partnering with SPEC Toolbox. We hope that this is an avenue to remove a little bit of the enigma and the mystery around mass timber construction, to compare effectively against all the other building materials — to know that not only are we the best aesthetic, not only are we the best from a biophilic perspective, but we can also be the best when it comes to the competitive cost of our materials. So SPEC Toolbox for us is an educational instrument in which we can start to penetrate additional markets that so far have been a little bit leery about using this type of material.”
