Designed for our systems. The EkoOknaTherm sill

Even the most energy-efficient, premium-class window will lose its properties if it's installed on a poor foundation. So that a faulty sill never ruins the results of your work, we have created EkoOknaTherm, a guarantee of solidity and real savings.

EkoOknaTherm – reliability for you, warmth for your client

The EkoOknaTherm sill, made of high-density rigid polyurethane, is a professional tool that protects your work and reputation. It gives you the arguments to convince any investor.

• Speed and precision of installation: forget about cutting and improvisation on the construction site. EkoOknaTherm features factory-made system grooves, guaranteeing a perfect fit for our window and door systems. It's clean, simple, and repeatable work.
• Guarantee of stability: confidently install even the heaviest HS sliding structures. The high compressive strength ensures a solid and durable support for the joinery for years, eliminating the risk of complaints.
• Order complexity: everything you need can be ordered in one place. When you order various products from Eko-Okna, including EkoOknaTherm, you can be sure that they are compatible and you are working with one entity instead of several.

Your client will benefit from lower heating bills, protection against moisture and mould, and peace of mind for decades, which for you will translate into no complaints and an unblemished reputation.

Don't let a random component ruin the effect of your work and the quality of our products. EkoOknaTherm is a logical addition to our offer and proof that we think about every detail of a project.

Protect your reputation and provide clients with the comfort they deserve. Ask your sales representative about the EkoOknaTherm sill base and order a free sample, or simply add it to your next order in the eko4u system.
