Timber Products - Olsen Doors and Windows Ltd

Wood is a living material and is affected by changes in the weather. Temperature and humidity variations cause the timber to expand and contract. Unless this movement is allowed for in the design, windows and doors can take on their own lives with consequent problems in closing and sealing. 

To overcome this all of their windows and doors are made from laminated Swedish redwood. The wood is sawn into thin sections and glued together to make up the frame members. This process provides greater strength, and evens out the stresses in the timber which in turn reduces the risk of warping and results in a construction which is strong, stable and durable.

Olsen Doors and Windows Ltd timber products are made with laminated sections containing 2 sections of spruce to the outer 2 pieces and pine to the inner. The spruce has a more coarse grain, which in turn is more resilient to harsh weather. The pine on the inside is a slower grown variety offering a tighter grain that is sanded down to a higher level – after all you will spend the majority of your time looking out of a window, not in!

To prevent rot and decay, the finalised sections undergo a vacuum impregnation treatment, with clear preservative, which can then be over coated with a micro-porous paint or stain finish, either in the factory, or by the customer on site. Site finishing must be done in clean, dry conditions and prior to installation in the building.
