Top quality epoxy resins are frequently utilized to combine softened wood and develop a seamless bond.
4. Glazing and Puttying
If the glass is broken or if the client chooses to update, the specialist will install brand-new panes. Numerous experts now provide "slimline double glazing," which fits into existing sash profiles while providing contemporary thermal insulation. Standard linseed oil putty is utilized to seal the glass, preserving the genuine appearance.

| Environmental Impact | Low-- reuses existing materials. | High-- manufacturing and disposal of plastics. |
| Thermal Efficiency | Exceptional with modern-day draught-proofing. | Excellent, however often visually jeopardized. |
