New Passivhaus-certified timber window range
We have recently discontinued Optiwin sales and are in the process of moving over to an alternative supplier of Passivhaus certified A rated windows.
We are very excited about this positive development, which will offer a high quality, cost-effective option for leading edge projects and designers.
Please fill in the form below, if you would like to be kept informed about this new product development as soon as it is launched.
In addition, our Ecocontract ULTRA timber window & door range offers a great option for Passivhaus & low energy projects and includes a Passivhaus-certified version with insulated frame.
