After using Conservation Joinery to upgrade and refurbish your windows our service will contribute to the energy efficiency of your property. Energy Performance Certificates are included within the packs to provide a simple means to compare properties based upon their energy efficiency and provide an A to G rating similar to white goods. If you produce this document and Conservation Joinery Guarantee to a H.I.P’s surveyor, it will assist him in his report to produce the certificate.
Draught proofing/upgrading your sash windows is up 80% energy efficient compared to double glazing. Energy efficiency rating is based on a “low cost” “high cost” or “further measures”. Due to the high cost of Double glazing it falls into the “further measures” category and has a 100 year payback period. Double glazing on a scale of 1-100 has a poor rating of 2-4 points. Therefore double glazed windows do not improve the energy efficiency as much as people are led to believe. Refurbishment of existing windows has 40 x less energy consumption than replacing with new windows. However the “u value” of a window only contributes to 20-30% of windows efficiency. Air leakage counts for up 70-80% of a windows efficiency this is greatly reduced by fitting “Conservation Joinery’s” draught proofing system and also Noise reduction is reduced by up 10 decibels. The draught proofing pile has a manufactures guarantee of 5 years, after 5 years an inspection can be done to check the serviceability of the pile. If the pile needs replacing due to wear and tear or excessive painting, Conservation joinery offers a Pile Replacement Service which is a fraction of the original cost of up-grading. However if during a Pile Replacement Service, any parts of the original box frame or any of Conservation Joinery’s repairs are found to be rotten due to the lack of re-decoration. We are not liable under the guarantee terms therefore we will quote for and carry out the repairs at an extra cost upon request.
