There is a frame insulator that covers a window or door frame. A door or window has one or more panels that are supported by frame members. The frame members have interior surfaces and exterior surfaces. The one or more panels are mounted on the frame members. The interior surfaces or the exterior surfaces or both are enclosed by sheets of cross-linked polyethylene foam extending adjacent to the one or more panels and forming frame insulators.

A fenestration assembly includes a glazing unit includes a pane spacer between exterior and interior panes proximate glazing unit edges. A fenestration frame is coupled around the glazing unit and includes a frame core extending around the glazing unit. The frame core includes a unitary core wall including a composite material that is hollow and extends continuously from a core interior face to a core exterior face. A metal glazing cap is coupled with the frame core. The metal glazing cap having a cap end indirectly engaged with the glazing unit along the interior pane, and the cap end is remote from the pane spacer. Each of the core exterior face, the pane spacer and the metal glazing cap are thermally isolated from each other with the frame core including the unitary core wall.

An integrated sash unit including a first sash portion. The first sash portion a first body portion and a first receiving wall extending inwardly from the first body portion. The first receiving wall has a first inner wall surface and a first peripheral wall surface opposing the first inner wall surface. The first body portion defines a first receiving surface and a first coupling surface and a first body peripheral surface opposite the first receiving surface and the first coupling surface. The integrated sash unit also includes a second sash portion forming a second body portion and a second receiving wall extending inwardly from the second body portion. The second receiving wall has a second inner wall surface and a second peripheral wall surface opposing the second inner wall surface. The second body portion defines a second receiving surface and a second coupling surface and a second body peripheral surface. The first coupling surface of the first sash portion is coupled to the second coupling surface of the second sash portion. The integrated sash unit also includes a first glazing panel supported by and coupled to the first inner wall surface of the first sash portion without being coupled to the second sash portion and a second glazing panel supported by and coupled to the second inner wall surface of the second sash portion without being coupled to the first sash portion.

The present invention describes a method for thermo-treatment of wood, where said method comprises the following steps: a) selecting the wood to be as free from knots as possible b) introducing the wood to a temperature increase up to approximately 173° C.; c) maintaining the wood at an ambient temperature of 173° C. for 3-5 hours; d) decreasing the temperature to approx. 20° C.; e) introducing the wood into an autoclave wherein a mixture of linseed oil and mineral oil is applied to the wood, and allowing the mixture to penetrate the wood f) retrieving and storing the treated wood. Furthermore a timber member made with wood treated according to the method is disclosed.

There is a frame insulator that covers a window or door frame. A door or window has one or more panels that are supported by frame members. The frame members have interior surfaces and exterior surfaces. The one or more panels are mounted on the frame members. The interior surfaces or the exterior surfaces or both are enclosed by sheets of cross-linked polyethylene foam extending adjacent to the one or more panels and forming frame insulators.

The process for the realization of reinforcing bars for door and window frames comprises: a step of providing a reinforcing bar (1) made of a metal material having a drillable face (2); and a step of drilling of the drillable face (2) to obtain a fixing hole (5) in the reinforcing bar (1) having a characteristic dimension (A) comprised between 2 mm and 5 mm, wherein the reinforcing bar (1) is insertable into a profiled element (4) made of plastic material and the fixing hole (5) is configured to be penetrated by the softened plastic material of the profiled element (4) to define a riveting portion (6) for fixing the profiled element (4) to the reinforcing bar (1).

An extrusion profile of, for example, a polymer material, such as PVC, for a door system and/or window system, may include at least one hollow chamber extending in the extrusion direction, which is delimited by profile walls; and an insulation core of foam arranged in the at least one hollow chamber. The foam may have a compression strength of at least 0.3 N/mm.sup.2.

There is a frame insulator that covers a window or door frame. A door or window has one or more panels that are supported by frame members. The frame members have interior surfaces and exterior surfaces. The one or more panels are mounted on the frame members. The interior surfaces or the exterior surfaces or both are enclosed by sheets of cross-linked polyethylene foam extending adjacent to the one or more panels and forming frame insulators.

Window and door opening assemblies are disclosed herein that incorporate one or more high-density insulation cores and methods for constructing thereof. The high-density insulation cores are comprised of polyurethane foam with uniform high density and high structural integrity.
