Frequently asked questions
Frequently asked questions about our shop
Which insulation is suitable for pouring?
For open, accessible areas such as timber joist ceilings or top-floor ceilings, loose cellulose and straw insulation is ideal. The specific choice depends on the structure, insulation thickness and use.
What makes up an airtightness system?
A complete system consists of a vapour barrier or airtightness membrane, suitable tapes, connection adhesive and grommets for penetrations. We stock coordinated systems from Targo and pro clima.
Which sealing is suitable for quick repairs?
For cracks, joints and smaller damage, depending on the surface, self-adhesive bitumen tapes or fibre-reinforced repair compounds such as Aqua-Dicht are suitable – ready to use immediately, even in wet conditions.
Do you also ship abroad?
Yes – we ship worldwide. Shipping costs for international deliveries are calculated during checkout. For larger quantities or questions about delivery to your country, please get in touch.
Are the products also suitable for DIY?
Yes. Alongside tradespeople and specialist contractors, we also supply private builders. Many products such as loose-fill cellulose insulation, bitumen tapes or liquid sealants can be applied without special machinery.
