Windows and doors can be finished in any RAL colour or combinations of colours.
To ensure the smooth operation and optimal performance, our windows have 3 coats of sprayed microporous water-based paint.
Deventer weather seals offer complete solutions for windows and doors. Wind, water, smoke and fire are the types of conditions these protect against. Not only do they protect against the elements but are also a useful addition to minimise energy waste by keeping warmth in and stopping draughts. With rainstorms and strong wind becoming more frequent, the functioning of your windows and doors can be easily affected so administering these seals will aid this.
